Protecting you from bacteria and viruses via a UV air purifier

With the development of technology, UV-C radiation has now become an increasingly popular function that is widely equipped in air purifier for consumers to have the better air quality in their indoor space.

Air purifier is a common air treatment device that is used to remove allergens in indoor air such as dust, pet fur, and pollen. Since the rising concerns about bacteria and virus transmission, many consumers have now mainly focused on the capacity of air purifier in eliminating germs when they deiced to choose a proper air purifier for their family. By scientific research, UV light has been known to be one of the effective ways to kill the bacteria and viruses in the atmosphere.  

In general, UV light can be divided by three types based on their wavelengths such as UV-A, UV-B, UV-C. In respect of air purifier, only UV-C would be more suitable to be applied for germicidal lights. With its wavelength of 100-279nm, artificial UV-C can highly be utilized in medical field to decrease the transmission of bacteria.

How does UV air purifier work?

The design of UV air purifier is to remained UV radiation within the air purifier. This would be safe for user to avoid the UV radiation as the UV light does not escape from device and air will be disinfected when it passes through the air purifier. When the bacteria and viruses are exposed to UV light, UV-C radiation damages the DNA of bacteria and viruses, which disables these bacteria and viruses from carrying out their normal functions. As the result, they lose their infectivity and die, but this might not be a quick process due to the fact that it has to take up to a few minutes of direct exposure to completely inactivate bacteria and viruses.

The concerns of using air purifier with UV function

As UV light is cable to damage the DNA, when user is accidently exposed to UV light, their skin and eye might be harm with certain degree. In order to avoid the damage, the following points need to be noted:

1. Ensure that the air purifier cover is securely closed to prevent any opening that exposes the UV light.

2. Ensure that the air purifier is not working when open the cover for filter change or cleaning

3. Ensure that the there is no big damage on cover of air purifier that close UV light. 

Vork has currently introduced a great number of air purifiers with different function such as UV light, ionizer and WIFI. It is guaranteed to provide best quality product alone with excellent customer service to the consumer for them to enjoy a better life.

 The Single-dose COVID-19 Vaccine Ad5-nCoV Suitable for Mass Vaccination Following the release of Phase III clinical data of two inactivated vaccines from Sinopharm Group and SINOVAC BIOTECH, the latest data of Ad5-nCoV, an adenovirus vector vaccine jointly developed by the team of Academician Chen Wei of the Academy of Military Sciences and Cansino Bio, was released on February 8.With only one injection, the protection rate can reach 74.8 %.Ad5-nCoV vaccine is the world's first COVID-19 vaccine to enter the clinical research phase which began on March 17 2020.And it is also one of the only two single-dose vaccines in the world that have released the Phase III trial data. Previously,the Johnson & Johnson in the United States announced the results of the its  adenovirus vaccine, with the overall protection rate of 66%.

The Phase III clinical trial of Ad5-nCoV was first launched in Pakistan on September 22, 2020.At present, clinical trials of the vaccine have been conducted in 78 clinical research centers in five countries on three continents and nearly 50,000 people have been vaccinated.In the results of the Phase III clinical trial conducted in Pakistan, 28 days after a single injection of the vaccine, the vaccine's protective efficacy against severe new coronary pneumonia was 100%, and the overall protective efficacy was 74.8%, without any serious adverse reactions related to the vaccine.

 Unlike inactivated and mRNA vaccines, this vaccine does not require two injections, and only one injection can be used for immunity, which is very important for the global promotion of vaccination. Although other countries in the world have successively developed COVID-19 vaccines and achieved some results, compared with international demand, it is still a drop in the bucket.

Ad5-nCoV is a single-dose vaccine so the procedure for vaccination is simple. It can vaccinate more people in the same period of time, which is beneficial to protect as many people as possible in the shortest time and can achieve rapid mass vaccination. It is reported that another advantage of the vaccine is that it only needs to be stored at 2 to 8 ℃, suitable for transportation and distribution.Mass vaccination requires a large number of refrigerators for vaccine storage.

The data have been submitted to the FDA to support a proposed update to the U.S. Emergency Use Authorization (EUA) Prescribing Information, which would allow for vaccine vials to be stored at these temperatures for a total of two weeks as an alternative or complement to storage in an ultra-low temperature freezer.

It is well known now that the Pfizer-BioNTech COVID-19 Vaccine can be stored in an ultra-cold freezer at temperatures between -80ºC and -60ºC (-112ºF to ‑76ºF) for up to 6 months. The vaccines are shipped in a specially-designed thermal container that can be used as temporary storage for a total of up to 30 days by refilling with dry ice every five days. Before mixing with a saline diluent, the vaccine may also be stored for up to five days at standard refrigerator temperature, between 2°C  and 8°C  (36°C  and 46°C ). If approved, the option to store at -25°C to -15°C (-13°F to 5°F) for two weeks would be in addition to this five-day option to store at standard refrigerator temperature. New storage option could offer pharmacies and vaccination centers greater flexibility in managing and maintaining vaccine distribution and supply. The vaccine is administered at room temperature by medical staff.

For new storage option,corresponding refrigerator is required. Actually,no matter which storage option you choose, Meling can provide you with suitable freezers and refrigerators.

Food hygiene directly affects people's health. Whether it is a processing workshop or a packaging workshop in a food factory, there are very high hygiene standards and requirements. Among them, microbial contamination is the most important factor affecting the quality of food, and it is also the focus of clean engineering in food packaging workshops and processing workshops. Therefore, in the field of food production, it must be clean and safe. According to national production standards, food clean rooms need to meet the 100,000-level air purification standard. The construction of clean workshops in food factories can effectively reduce the deterioration of the products produced, extend the shelf life of food, and improve production efficiency. As the largest manufacturer of cleanroom panels in China, Wiskind puts forward the following precautions for the construction of food cleanroom factories.

1. What is a clean room?

Clean room is also called dust-free workshop, clean room, and clean room. It refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, Air velocity and air distribution, noise, vibration, lighting, and static electricity are controlled within a certain range of requirements, and a specially designed room is given. No matter how the outside air conditions change, the room can maintain the originally set required performance characteristics such as cleanliness, temperature, humidity, and pressure.

What is a class 100,000 clean room?

There are no more than 3.52 million particles with a diameter of ≥0.5μm per cubic meter of air in the workshop. The fewer particles in the air, the less dust and microorganisms, and the cleaner the air. The 100,000-class clean room requires 15-19 air exchanges per hour in the workshop, and the air purification time after complete air exchange does not exceed 40 minutes.

How is the food clean room distributed?

General food clean room can be divided into three areas: non-clean area, quasi-clean area, clean operation area.

Non-clean areas: general storage areas for raw materials, finished products, tools, packaging and finished products transfer areas and other areas with low exposure risk of raw materials and finished products, such as outer packaging room, raw and auxiliary material warehouse, packaging material warehouse, outer packaging workshop, finished product warehouse, etc.

Quasi-clean area: no need for secondary dressing, such as raw material processing, packaging material processing, packaging, buffer room (unpacking room), general production and processing room, non-ready food inner packaging room and other finished product processing but not directly exposed areas.

Clean operation area: Refers to the highest sanitary environment requirements, personnel and environment requirements are high, and must be disinfected and changed before entering, such as: raw materials and finished products exposed processing areas, cold processing rooms for edible foods, cooling rooms for ready-to-eat foods, and waiting for packaging Storage room for instant food, inner packaging room for instant food, etc.

Points to note in clean room construction?

1. The calculation of air exchange rate in the workshop must have sufficient air exchange rate and ensure positive pressure.

2. The temperature and humidity control in the workshop has reached the requirements.

3. The locker room, buffer room, hand washing and disinfection, and other facilities for the staff's secondary change are designed to meet the requirements of the staff.

4. The design of the air shower room.

5. The installation of environmental disinfection facilities in the workshop, such as ultraviolet lamps.

6. The installation of anti-rodent and fly-proof facilities in the workshop, such as fly-killing lights.

7. The location of the air inlet of the workshop should be set up at the air inlet, and there should be a filter system, and should be closed when the machine is shut down.

8. The design of the return air outlet or the return air wall ensures easy cleaning.

9. Treatment of the workshop floor and sewers without stagnant water, and ensure that the sewers are deodorized.

10. The design of the safety door in the workshop to ensure the safety of employees.

1. What is FFU?

FFU is the English abbreviation, its full name is Fan FiIter Units, which means "fan filter unit" in Chinese. To be precise, it is a modularized terminal air supply device with its own power and filtering function. FFU keel is a modular ceiling material (FFU aluminum alloy keel) specially provided for this modularized terminal air supply device, mainly the main material of cleanroom blind ceiling.

The joints are connected by joints, including cross joints, T-shaped joints and corner joints. The entire FFU keel system is reinforced with some threads to form a whole.

2.Unique advantages:

1.The FFU keel is designed according to the characteristics of the clean room. It has a processing tube and is easy to assemble and disassemble, which is convenient for daily maintenance after the clean room is built.

2.The modular design of the ceiling system has large plasticity, which can be factory-produced and cut on site, which greatly reduces construction pollution.

3.The combination of this product is flexible, and a double-layer ceiling structure can be selected, or a single-layer ceiling with only the lower FFU keel can be used.

4.The system has high strength and can walk on the FFU aluminum alloy ceiling keel. It is suitable for local laminar flow systems, FFU systems and air purification systems of different cleanliness levels, and is suitable for electronics, semiconductors, and pharmaceutical industries.

5.The composition of the FFU keel system is also very diverse. You can install the sprinkler at the cross joint, or install some wires for the smoke detector and the lighting lamp. The clean room teardrop lighting can be installed below, and the FFU ceiling can be used with FFU at the same time. Use with fan filter unit.

In recent years, food safety issues have occurred frequently. An epidemic has made us feel the importance of food safety, especially the nutrition of students, and it has made countless parents full of worries. At present, students’ nutritional meals are uneven, the standards are not uniform, and the workshop design is backward. Looking at various conditions, it is difficult to meet the requirements of the new era for students’ nutritional meals.

In order to ensure risk-free of food safety, it is necessary to uniformly complete the procurement, storage, processing, packaging, sample retention, transportation, cleaning and disinfection of dishes in the central kitchen. Therefore, during the construction process, cleanroom wall panels need to have the advantages of corrosion resistance, high temperature resistance and easy cleaning.

Wiskind provides more than 20,000 square meters of stainless steel cleanroom panels for the Shizhicai Nutritional Catering Center, which fully meets the needs of food cleanroom wall panels. Shizhicai Nutritional Catering Center mainly serves the students of various campuses, employees of large,medium and small enterprises, providing professional nutrition, hygiene, and delicious food service, and providing consumers with healthier and nutritious fast food services.

Secondly, the key point in the construction of food workshops is waterproofing. Since processing utensils need to be cleaned and disinfected and cooking, etc., so they need to be washed frequently. Therefore, when installing cleanroom walll panels on the ground, they must be treated with waterproof floor groove. Wiskind has introduced a new stainless steel waterproof floor groove node to solve the waterproof problem. The new stainless steel  waterproof floor groove completely avoids the problem of corrosion and blistering of the panel surface due to washing, which affects the service life of the plant.

Wiskind starting from customer value, focusing on cleanroom enclosure system solutions, further exerting our own advantages, better serving customers, enhancing brand image, and making every effort to maintenance food safety and health.

In late-stage clinical trials in Brazil, Sinovac Biotech's vaccine has shown 78% effectiveness in fighting COVID-19, and 100% can prevent severe illness.

China Sinovac Biotech cooperated with Butanta Research Institute, Brazil's largest vaccine manufacturer, to conduct Phase III clinical research in Brazil. The agency said on Thursday that among the volunteers vaccinated, there were no severe cases. Although the effectiveness of Sinovac Biotech CoronaVac vaccine is not more than 90% like Moderna, this vaccine is easier to transport and can be stored at normal refrigerator temperature.

In December 2020, Sinovac Biotech announced that it is expected to produce 300 million doses of vaccine in 2020 and increase its production capacity to 600 million doses per year. Sinovac Biotech built a factory in Beijing for the production of COVID-19 vaccine. At present, Sinovac Biotech's vaccine research and development laboratory in China is provided by Wiskind with cleanroom materials, using a total of 15,000 square meters of cleanroom panels.

Clean room door and window gap treatment: Generally speaking, clean room doors and windows have three types of structural gaps. The first category is: the combined splicing and the installation gap between the door and the clean room door; the second category is: the overlap gap between the door and the opening fan; the third category is: the installation gap between the glass or other core boards. The nature is different and their proportions on the clean room doors and windows are also different. Therefore, the airtight measures adopted for the airtightness of clean room doors and windows are not completely the same.

  Fixed gap treatment: Not only is the number of installed gaps in each clean room relatively small nowadays, but the combination of the door and the opening is relatively hidden after decoration, and it is a fixed gap that is easier to seal. The connection between the rib and the periphery of the hole should be firm, not only for the closed clean room doors and windows, but also the requirements of the general clean room door structure. Due to the large and fierce force of the clean room door, special attention should be paid to the process and the fixing of the clean room door. Whether the fixed points around the opening are firm and stable, but for closed clean room doors and windows, it must also be emphasized that the gap between the chamber and the clean room door or the hole should be tightly filled, and then covered with indoor and outdoor wall decoration layers. The air tightness of this type of gap is basically guaranteed. The second type of fixed gap is the installation gap of glass or other core panel.

The treatment of the movable gap: How to overlap the opening fan of the clean room door and the frame material is the key to the design of the clean room door seal. The gap in the lap joint is different from the fixed gap. Because the movable fan needs to be opened, the wood can adopt the "one-and-for-all" sealing measures. Compared with Zhou, the opening fan of the clean room door is larger, and the movable gap occupies a larger proportion of the total structural gap of the clean room door. The number of openings of the clean room door is much more frequent than that of the clean room. The working conditions of the gaps around the door leaf are also more complicated. Take a single flat open clean room door as an example. The two sides along the vertical direction are small. The side with the handle is often subjected to various frictions or collisions during passage, and the side with the hinge is The direction of force applied to the bore due to the rotation of the fan is completely different from the other three sides.

We are professional manufacturers  of sliding doors clean room、clean room window、aluminium room door etc.

Operating room laminar flow air supply ceiling-clean air supply ceiling is the clean operating room, the purifying air supply end of the laminar flow ward, it has the functions of high efficiency filtration, flow sharing and air flow compensation. The rationality of the structure of the laminar flow purifying air supply ceiling directly affects the air supply effect and purification level of the operating room. KLCFILTER laminar flow air supply ceiling is the crystallization of the experience and practice of operating room air supply terminal in the past ten years. This type of terminal has been used in nearly a thousand operating rooms. Its superior performance and unique double-layer DPP flow-sharing network energy The airflow is evenly sent to the working area, and the central airflow compensation device can effectively eliminate the influence of updraft caused by the heating of personnel and equipment on the laminar flow. To Operating room laminar flow air supply ceiling-clean air supply ceiling Working principle: The air supply ceiling consists of a high-efficiency air disinfection and filtration system, a fan power system, a noise reduction system, and an operation control system. When working, the fan inhales ambient air, filters it into clean and sterile air through the air purification and disinfection system, and then delivers clean air to the hospital bed area in the cover in a laminar flow, while maintaining a positive pressure in the cover to prevent dust in the external space Particles and microorganisms enter the hood. With the rapid development of modern medical science and technology, surgical technology has increasingly higher requirements for the clean conditions of the operating room. The 100-level laminar flow operating room is currently the most ideal. However, how to effectively manage the number of air colonies in the laminar flow operating room to meet the air environmental hygiene standards issued by the Ministry of Health, and to meet the clean operating room grade standards, and to reduce it to a minimum. There are few domestic search documents and data. A new topic worth discussing in the management of clean operating room. Laminar flow air supply ceiling adopts air cleaning technology to control microbial pollution in different degrees to achieve the requirements of air cleanliness in the controlled space environment and suitable for various operations; and provide suitable temperature and humidity to create a clean and comfortable operating space surroundings.

Features of laminar flow ceiling:

The use of this equipment can reasonably distribute the air flow in the clean room and effectively ensure the indoor cleanliness (air supply surface level 100).

cleanrooms false ceiling

Hospital operating rooms have very high environmental requirements. How is the air filter installed in the hospital operating room? Today we will introduce the installation principle of the air filter in the hospital operating room.

To An air filter in a hospital operating room generally consists of two parts: three air conditioners and two purifiers. The working principle of medical air filters is divided into eight parts:

Part 1: Return air section The return air section means that the air volume sent by the exhaust fan reaches the specified air volume, and the recovery system of the medical air filter can send out air.

Part 2: Primary filtration Primary filtration is the first filtration procedure performed by non-wind. In this step, we need to replace or clean the equipment for a certain period of time.

Part 3: Heating process The heating process is generally an electric heating process used for heating in winter.

Part 4: The humidification stage of the medical air filter The humidification stage is mainly to humidify the blower unit through a humidifier, and then reach the temperature for people's affairs.

Part 5: Secondary Filtration This is the final filtration stage of the air filter in the hospital operating room. This stage is the final pass to ensure air quality. The air is filtered once, then humidified, and finally filtered again. This ensures the purity of the air and can achieve the medical air filtration effect. Then the filtered air is output.

Disinfectants and electronic sterilization devices are necessary daily cleaning items in every family. Especially in the season of a high incidence of influenza and other infectious diseases, the frequency of use of disinfection products will increase significantly. Home UV sterilizers are the most common electronic sterilization devices in modern homes, and because of this year's special circumstances, many new types of UV sterilization devices are being accepted by consumers faster, including home UVC Air sterilizers, UV cutting board sterilizer, etc.

So what are the advantages of UV sterilization? Why has it become the preferred method of disinfection?

Effective Against More Germs

UV sterilization is a physical sterilization method that directly acts on the genetic material in biological cells. It destroys DNA and RNA to achieve the purpose of killing bacteria and viruses. Therefore, except for a few rare super bacteria, UV sterilization can effectively kill most bacteria and viruses. For the common germs in the home environments, efficient UVC germicidal lights are enough to meet cleaning needs

Fast & Efficient

UV rays are very efficient at destroying DNA and RNA. UVC rays of sufficient intensity can even kill bacteria within 1 second. So UV sterilization is very fast, but the sterilization time preset in different UV sterilization device is usually different because of different cleaning needs. For example, a LED UV sterilizer boxthat for cleaning daily small items just needs 5 minutes to achieve the required sterilization rate, and a high-power UV sterilizer used for sterilizing the medical device usually rules the sterilization time as 30 to 60 minutes.

Non-contact, No chemical residue

UV sterilization is carried out by light irradiation, and the cleaning work can be completed without touching the objects, which is very sanitary and convenient for the operator. And because of the characteristics of light, it will not leave any chemical by-products on the object after sterilization. So, UV sterilization is more safe and friendly to both the environment and users.

Energy Saving

UV sterilizers are representative of low energy consumption in electronic disinfection equipment. The daily power consumption of some small UV light air purifieris even less than 0.2 kwh.

At present, UVC LEDs, which are more energy-efficient and efficient than traditional fluorescent tubes, have been widely used in more products. It is believed that many UV sterilizers will have better energy-saving performance in the near future.

Low Cost

The UV sterilizers are the disinfection equipment with a mature technology that has been used for many years. Most of the UV sterilizers just need simple maintenance and their service life can reach thousands to tens of thousands of hours. This is a cost-effective way of sterilization and cleaning method for most families.

Because it has so many obvious advantages, ultraviolet sterilization has become one of the most trusted and favorite methods of disinfection. However, it should be noted that UV also has some shortcomings, users still need to follow the instructions carefully to use them, to safely and effectively use UV to complete the sterilization work.

If we can turn container into homes, then surely we can turn shipping containers into one of our homes’ greatest accessories — pools. One company is doing just that-CBOX， who is a design company specializing in transforming containers into houses, and recently it has launched a project to transform containers into swimming pools.

The swimming pool has a built-in hot water system that can be raised by 10 degrees Celsius per hour, and the swimming pool can be divided into hot and cold water areas through a dedicated dividing plate to experience different water temperatures. Compared with traditional swimming pools that need to be dug, the installation method ofswimpoolsis much more flexible and does not have too high requirements on the soil. If you put it directly on the ground, you can also enjoy the scenery outside through the "window".

Shipping containers are naturally durable and structurally sound,Repurposing a shipping container cuts down the carbon footprint and turns something that may have not been useful into what we think is a lifestyle changing, modern asset.

Modpools are just 50 percent of the cost of conventional in-ground pools, and come with a hot tub and pool area that can be separated in the cold months. That means you can decide which portion to heat, and enjoy the separate benefits of both a pool and a hot tub, all for one comprehensive price.

shipping container pools would be easy to install ？

A pools ship completely ready to use with all the pool equipment built in. With some light ground prep, power and gas access, you can simply plug and play。which features a window on its side, can be installed where traditional in-ground pools can’t be. Many people have ground that is too hard because of rock or, alternatively, have ground that is too soft because of high water levels. We can be placed above ground with decks built around, partial in-ground behind retaining walls or completely in-ground. We find many of our customers want a pool but are unable to have a traditional pool installed.

And because it’s easy to install, it’s also easy to move — that means no more leaving your pool behind when you move. This is a vast departure from a traditional pool, and makes our pools a smart lifestyle and financial choice.

The hospital’s clean room is a biological clean room. The hospital’s biological clean room is airtight. After reasonable zoning, process design, air purification and other construction links, it can effectively reduce cross-infection and control the spread of bacteria and viruses in the air. During the construction, Wiskind Cleanroom discovered that the biological clean rooms of many hospitals have hidden dangers of congenital deficiencies, and there are many social problems such as concept, plan, design, equipment configuration, construction technology and so on.

1. Can the positive pressure clean operating room operate on patients infected by this epidemic?

The main route of transmission of this epidemic is droplets attacking the respiratory system and mucous membranes through the air. At the same time, droplets are also contaminated on the surface of objects and are transmitted through human contact . The transmission routes are multi-directional. It is recommended that such infected patients should be operated in a negative pressure operating room. However, if there is no negative pressure operating room in the operating department of some hospitals, and the patient must perform the operation, the operation should be arranged in an operating room with a separate area as much as possible.

2. If an operation is performed on a severely infectious patient in a positive pressure clean operating room, how to disinfect the purification unit system?

After the positive pressure clean operating room is operated on patients with severe infectious diseases, the disinfection requirements are the same as those of the negative pressure operating room. In addition to the operating room to cleanroom wall panels , roof, floor, cleanroom door, outlet and all indoor facilities and equipment to conduct a comprehensive, thorough, serious, no dead outside cleaning disinfection, but also carefully clean up all the gaps, strict disinfection.

In terms of purifying the air system, the professional team of professionals should replace the return air filter, the circulating unit filter, the air supply port (or air supply ceiling) high-efficiency filter, and the exhaust system filter under the premise of self-protection. , The replaced filter should also be disinfected, sealed and then disinfected.

Carry out careful and thorough disinfection of air ducts participating in circulation and discharge and fresh air supply ducts without check valves. It is best to use atomized hydrogen peroxide for air duct disinfection.

It is also necessary to carry out disinfection and sterilization measures for the participating unit systems, which mainly refer to the circulation unit, the inside and outside of the exhaust fan unit, and the computer room.

3. What is the main difference between a positive pressure clean operating room and a negative pressure operating room?

The positive pressure clean operating room is an operating room with clean levels (level I , II , III , IV ). Its air system is composed of treated clean fresh air + circulating clean air with different air changes + exhaust air , That is, there is fresh air, circulating air, and exhaust air. The starting sequence of the fan should be fresh air, circulation and exhaust air. The volume of fresh air sent to the operating room is greater than the volume of exhaust air. The relative pressure in the operating room is greater than the pressure in the adjacent room. Its protection objects are mainly surgical patients. Because the exhaust vent of the clean operating room is mostly designed on the top of the operating room, the exhaust fan is a single fan system, and the exhaust air does not need to be equipped with a high-efficiency filter, but only a junior high-efficiency filter.

The negative pressure operating room is generally an operating room with no cleanliness level. Its air system is composed of treated clean fresh air + exhaust air, that is, direct delivery and direct exhaust. The starting sequence of the fan should be exhaust air, fresh air, and the fresh air volume sent to the room is less than the exhaust air volume. The relative pressure in the operating room is less than the relative pressure in the adjacent room. Its protection objects are mainly medical staff and the surrounding environment. The air outlet of the negative pressure operating room should be located at the lower end of the side wall of the operating room close to the patient's head and on the side of the top anesthesia work area. The exhaust fan system is a double fan. The exhaust air must be equipped with a high-efficiency filter.

4. How can we know that the clean room and related controlled environment of our hospital are safe during use?

The main purpose is to be "controllable" and "knowable" for the key parameters designed in accordance with the relevant national standards for the clean room and related controlled environment of our hospital. That is to say, the use process of the clean room and related controlled environment in our hospital is a dynamic process (infection also occurs in the dynamic process), and various parameters of the environment are realized in the dynamic process. Real-time monitoring and management of parameters can realize whether the environment is safe or not. However, the clean rooms and related controlled environments of most hospitals in our country do not have real-time management configurations, so it is basically impossible to know whether our own clean rooms and related controlled environments are safe. This is a shortcoming in the construction and use of clean rooms and related controlled environments in our national hospitals.

Some hospitals now install pressure display devices in clean rooms, so that you can know whether the air in the clean room is leaking and the general situation of organized air flow. However, the pressure of many hospitals shows that the values displayed by the facilities are ridiculously deviated, which can mislead us.

At present, the method of bacterial sampling and culture readings in clean rooms and related controlled environments in hospitals can most directly reflect the safety status of hospital clean rooms and related controlled environments. Although there are many indicators for the safety factor of hospital clean rooms and related controlled environments, they are comprehensive, but the bacteria indicators are the most critical and important. However, it takes a long time for bacterial samples to be cultured and the feedback of safety information is delayed. If it is in an extraordinary period of the fight against the epidemic, it is recommended to increase the time density of bacterial sampling and analysis in key areas.

5. If the hospital is to rebuild some negative pressure isolation wards in the existing buildings, what aspects should be paid attention to?

MasterCard believes that the most critical issue in the construction of negative pressure isolation wards in hospitals is the concept. Although the negative pressure isolation ward of the hospital and the clean operating room, ICU , supply room, liquid distribution center, laboratory, etc. are all controlled environments, the negative pressure isolation ward is not a clean room and does not require expensive air purification systems.

Negative pressure isolation wards are mainly used to treat patients with respiratory infections. The principles that must be followed when designing are to control the air transmission of the virus, cut off the air transmission chain of the virus, and simultaneously implement physical separation and air isolation of the source of infection. When designing, we must insist on: zone prevention and control, layer by layer check; process safety, reasonable and convenient; isolate the source of disease and cut off transmission.

It is best to use a dual-channel mode for partitioning, which can be divided into clean area, semi-contaminated area (also regarded as a buffer zone), ward area (contaminated area), and other auxiliary areas. Each area can be an independent area, and each area is divided or connected in the form of a buffer.

The flow of people and things must be "buffered." Each area requires functional satisfaction and complete equipment. All items that need to be removed from the contaminated area and semi-contaminated area, especially patient excrement and medical waste, shall have special areas for disinfection, sorting and packaging, and re-sterilization.

The air isolation system uses an organized gas flow pattern. The air supply in polluted and semi-polluted areas adopts full delivery and full exhaust. The fresh air should be treated, with initial, medium and sub-high efficiency filter sections. The exhaust fan unit should be equipped with dual fans, one fan is used and one is prepared, and the standby fan can be quickly started. The external discharge of the exhaust system must pass through a high-efficiency filter section, and a qualified and effective check valve must be installed. The exhaust vent must have a certain height, and the discharge direction must be reasonable.

Arrangement of air supply and exhaust vents: The air supply vent of the isolation ward should be located at the top of the side where medical staff enter the operation area of the ward, and the exhaust vent should be located on the underside of the wall near the patient's head in the bed. The air outlet for the buffer zone should be located at the lower end of the wall near the isolation ward. The air outlets of the clean area are arranged according to the position of the air-conditioning outlets of the normal normal office area. The temperature of the isolation ward should be set not less than 22 ℃, and can be moderately higher if possible.

Pressure gradient setting: For the design of a completely independent indoor negative pressure isolation ward, it is best to have a positive pressure buffer channel at the beginning of entering the area, and use positive pressure to protect and separate other areas. The clean area is normal pressure Zone, the buffer zone starts as a negative pressure zone. The isolation ward and the sewage treatment and disinfection room are the main negative pressure area, and the pressure gradient is the highest negative pressure in the entire area.

The number of air changes is set to 12 , which does not mean that fresh air must be sent in 12 times and the air volume must be discharged 12 times. The American standard is also 12 times of air change, but they only send in fresh air for 2-4 times and discharge 12 times of air. The large amount of 8-10 times air volume is the air volume leaked from other areas. The door of the negative pressure isolation ward does not need an airtight door, and it is normal for other areas to vent into the air.

In addition, the operating parameters of the negative pressure isolation ward should be set to remote real-time monitoring mode. The isolation ward should be equipped with high-definition video screen equipment to remotely observe the patient's condition in real time. The sewage discharge from the negative pressure isolation ward is not allowed to be directly discharged to the corresponding sewage discharge system of the hospital. The sewage must be equipped with disinfection equipment and can be discharged after disinfection.

The use of negative pressure isolation wards to treat severely infected patients is an effective means to control the source of infection and cut off the air transmission chain. The hardware construction is one aspect, and the other aspect: use and management are equally important.

Through research over the past few months, many scientists from all over the world have proved that UV can effectively kill the COVID19. As recently as July, researchers from Columbia University said they had solid evidence that UV could effectively kill coronaviruses, including COVID19, H1N1 flu viruses etc. Scientists believe that this study provides a new weapon and theoretical basis for the fight against this epidemic.

Before this, many innovative companies invested their technological power in the innovative R&D of ultraviolet products ahead of time because of the prediction of the market and tech. Until now, there have been a number of new UV products on the market, and most of them have got positive feedback from the market.

Masks are important protective equipment that has attracted much attention in this epidemic. Recently, several new UV sterilization masks have displayed on some well-known online crowdfunding platforms. Tech companies combined UVC germicidal light into traditional filter masks to develop new products with disinfection and self-purification functions. These UV germicidal masks are popular with consumers while they just hit the market, raising millions of dollars each on crowdfunding platforms in just over a dozen days.

UV makeup brush sanitizer is also a kind of new product that is very popular in the market at present. Compared with the ultraviolet disinfection mask, the UV tool sterilizer box dryer is a micro-innovation of products by professional disinfector manufacturers. Combine the beautiful desktop storage box with UVC disinfection technology, with sufficient disinfection room, beautiful looks, unique germicidal drying function and clean storage function. The launch of this product not only meets the needs of disinfecting small daily items during the epidemic, but also meets the daily needs of many people to store clean items. So, this product has been included in the purchase list by many professional buyers as soon as it was launched.

Not only these, but also many innovative products using ultraviolet disinfection technology, such as UV air cleaner specializing in disinfection air, Smart elevator UV cleaner Light with automatic cleaning function, and so on, have become the most popular product choices in the current market. And it is believed that in the coming future, there will soon be more innovative UV devices recognized by consumers on the market.

With the development of computers, microelectronics and information technology, the rapid development of the electronics manufacturing industry has been promoted, and the development of clean room technology has also been promoted. At the same time, higher requirements have been put forward for the design of modular clean rooms. The clean room design of the electronics manufacturing industry is a comprehensive technology.

Only by fully understanding the design characteristics of the dust-free workshop of the electronics manufacturing industry and achieving reasonable design, can the product defect rate of the electronics manufacturing industry be reduced and production efficiency improved.

Features of electronic clean room

The cleanliness level is required to be high. The air volume, temperature, humidity, pressure difference, and equipment exhaust are controlled on demand. The illuminance and clean room section wind speed are controlled according to design or specifications. In addition, electronic clean rooms have extremely strict requirements for static electricity.

Among them, the requirements for humidity are strict, because static electricity is easily generated in an excessively dry plant, which can cause damage to the CMOS integration.

Generally speaking, the temperature of the electronic workshop should be controlled at about 22℃, and the relative humidity should be controlled between 50-60% (special clean workshops have relevant temperature and humidity regulations). At this time, static electricity can be effectively eliminated and people feel comfortable.

Chip production workshops, integrated circuit clean rooms and disk manufacturing workshops are important components of clean rooms in the electronics manufacturing industry.

Since electronic products have extremely strict requirements on the indoor air environment and quality during the manufacturing and production process, they mainly control particles and floating dust as the main object. At the same time, strict regulations are made on the temperature and humidity of the environment, the amount of fresh air, and noise.

Factors affecting cleanliness

As a huge purification system, the clean room has a large area, but also needs to be divided into complex functional partitions and corresponding buffer supporting rooms, which together constitute a complex air supply and return system.

Therefore, there are many factors that cause the cleanliness of the clean room to be unqualified. mainly includes:

(1) Design level and air conditioning layout

The design level of the clean room and the air conditioning layout are directly related to the cleanliness level of the clean room.

(2) Construction level

The overall construction quality of the plant, the installation quality of the air-conditioning system, air supply system, sewage system and other guarantee equipment are closely related to the cleanliness of the clean room.

(3) Airflow organization

If the airflow organization is unreasonable, the supply airflow cannot fully cover the work area.

The unreasonable position of the air supply and return air outlets will produce higher and larger eddy currents, and the air flow deflection angle of the unidirectional flow clean room is too large.

If the opening area of the return air grille is unreasonably arranged, the return air speed is too high and the return air is not smooth.

(4) High efficiency filter

High-efficiency filter quality problems or installation problems cause the air sent into the clean room to not be effectively filtered, and some dust particles suspended in the air are not filtered, resulting in unqualified clean room cleanliness.

(5) Number of air changes

Insufficient air changes will cause the polluted air in the clean room to not be quickly discharged from the clean room, and too low air changes will not be able to inhibit the pollution of dust sources.

(6) Static pressure difference

The unqualified static pressure difference makes the clean room unable to block the external pollutants from entering the clean room.

(7) Air shower

The air shower room is used as a necessary channel to enter the clean room to reduce pollution problems caused by entering and leaving the clean room. Therefore, its quality is closely related to the cleanliness of the clean room.

(8) Equipment placement

The unreasonable placement of indoor equipment will affect the air flow in the clean room from top to bottom, from the center to the surroundings, causing air turbulence and preventing pollutants from being effectively discharged from the clean room.

(9) New equipment moved in

The process of moving in new equipment needs to connect the clean room environment with the outside atmosphere. Therefore, it is necessary to strictly control the moving-in time and the transportation and installation process of the equipment. At the same time, the outer packaging of the equipment must be strictly wiped and cleaned before being moved in.

(10) Chemical substances

Chemical substances in raw materials and derivatives in the production process will produce certain volatiles, which will affect the cleanliness of the clean room.

(11) Cleaning level

Incomplete cleaning of the clean room will result in the accumulation of pollutants in the room, resulting in sanitary blind spots.

(12) Personnel and material operation

During the operation of the clean room, the movement of personnel and materials can easily produce air turbulence around pollution-sensitive activities, which is the main source of pollution for cleanliness.

Excessive material flow, excessive number of operators, and improper wearing of clean clothes will all cause excessive dust emission.

Accidents caused by static electricity in clean rooms frequently occur. Therefore, the anti-static ability of clean rooms has become an aspect that cannot be ignored in evaluating its quality. The so-called static electricity is that due to friction and other reasons, the uniform neutral state of the positive (+) and negative (-) charges in the object is destroyed, so that the charge is excessive and the object is in a charged state. Because these charges usually do not flow, so Called static electricity.

Accidents caused by static electricity in the clean room include the following aspects in the clean engineering field that has strict requirements for the indoor environment:

1. Electrostatic shock caused by static electricity can cause people's insecurity and fear, and can cause secondary injury.

For example, when a person falls due to an electric shock, he falls and causes injuries.

2. Discharge current caused by electrostatic discharge can cause damage and malfunctions such as semiconductor components.

For example, if 50 P-MOS circuits are placed in a plastic bag and shaken several times, 39 NAND gates have been severely broken down, with a failure rate of 78%. This is because semiconductor devices are very sensitive to electrostatic discharge.

3. Electromagnetic waves generated by electrostatic discharge can cause noise and malfunction of electronic instruments and devices.

4. The luminescence of electrostatic discharge can cause damage to the photosensitivity of photographs.

5. The mechanical phenomenon of static electricity can cause the sieve holes to be blocked by dust, the spinning yarn is chaotic, the printing depth is uneven and the product is contaminated.

6. The most dangerous disaster caused by electrostatic discharge is the explosion caused by the fire source well that becomes combustible.

For example, according to foreign literature statistics, among the 86,000 explosive anesthetics used in the operating room, 36 explosions occurred, of which 21 were caused by static electricity.

The occurrence of static electricity accidents mainly lies in the generation and accumulation of static electricity, and the flow of airflow, the friction between airflow and pipes, vents, filters, etc.

The friction between the human body and the clothes, the friction between the clothes, the grinding process, spraying, jetting, washing, stirring, bonding and peeling, all of which may generate static electricity.

In general, the smaller the conductivity of the non-conductor (insulator), the easier it is to be charged because the charge is not easy to flow after generation.

The problem of static electricity is particularly serious in clean rooms because it not only has the aforementioned various process factors that generate static electricity in the clean room.

Moreover, because many materials in the clean room, such as plastic floors, walls, nylon and other work clothes, have high resistivity, they are very easy to generate static electricity and accumulate static electricity. Before the static electricity disaster in the clean room was not taken seriously, these materials Is widely adopted.

With the development of science and technology, the requirements for antistatic, antibacterial and dustproof in the field of cleanroom engineering are getting higher and higher. Sparks caused by static electricity are prone to fire and explosion, and will affect the normal operation of electronic equipment; environmental pollution produces more bacteria, some (such as Staphylococcus aureus) antibiotics have been ineffectively suppressed, and pathogen infection makes people with weak resistance Life is threatened. In response to higher demands, Wiskind is the first to introduce high-efficiency anti-static, anti-bacterial and dust-proof cleanroom panels in the clean field.

The antistatic cleanroom panel uses the color board coating to add special conductive pigments to make the surface of the color board have a resistance of 10-100. Static electricity can be released through this to prevent dust adhesion and easy to remove. At the same time, the pane is resistant to chemicals, The advantages of wear resistance and pollution resistance. A special antibacterial agent is used in the color plate coating of the antibacterial cleanroom panel, which has a non-toxic and semi-permanent antibacterial effect and far-infrared radiation effect.

In the industrial society, standardization and industrialization have become a trend, and the industrialization of houses and modular container houses have been widely discussed in the world. In Europe and Japan,modular container houses have been applied in the middle of the last century. Since the beginning of the new century, China's huge demand for housing and tourism housing, with the research and implementation of housing boxes, modular container houses, and industrialized housing, whether it can alleviate the sensitive housing nerves of the Chinese is still unknown, but at least it is certain What's more, with the development of new materials and new processes, modular box houses or modular container houses will perform a wonderful future in the application fields mentioned above. At least in developed economies, it is no longer a low-end residential term.

Modular container houses are accepted by more and more people for their highly industrialized production methods, efficient on-site installation levels, excellent performance, and healthy home product concepts.

In 2020, a new type of coronavirus is coming, and Many people go to the scene to fight against the epidemic during the Spring Festival. modular container houses also participated. Completed two high-standard Vulcan Hill and Thor Mountain Hospitals in just 15 days.

The industrialized production characteristics of the modular housing system provide an effective carrier for this revolution. Government departments are also vigorously promoting the development of the construction industry towards industrialization and industrialization. modular container houses are more and more popular for their highly industrialized production methods, efficient field installation levels, excellent performance, and healthy home product concepts. Accepted by people.

The modular house system has complete energy-saving energy storage technology, and the energy-saving effect can reach more than 75%. modular container house sandwich panel walls use environmentally friendly renewable materials, which is conducive to environmental protection. At present, the multi-story residential structure system in China is mainly masonry structure and concrete frame structure. Portland cement material is widely used. Portland material is a non-renewable resource, and it will become a waste that is difficult to recycle and reuse after the building is disintegrated Things, causing great damage to the environment. In addition to the concrete structure of the foundation and core tube, the modular container houses use environmentally friendly and renewable materials, which greatly reduces the use of concrete.

A steel structure is a structure in which a stress member is made of steel. Steel structure housing is valued by all parties for its comprehensive advantages such as light weight, low foundation cost, suitable for weak foundations, easy installation, fast construction, short cycle, fast investment recovery, less pollution to the environment and good seismic performance.

WISKIND is the first grade enterprise of national qualification for steel structure manufacturing, the second grade enterprise enterprise of construction qualification and group member of China steel structure society.

Compared with other structures—brick-concrete structures and concrete structures, steel structures have advantages in terms of function, design, construction, and comprehensive economics. The advantages of using steel structures in residential buildings are mainly reflected in the following aspects:

1.Reasonable arrangement of functional intervals

Using the characteristics of high strength of steel, the design can adopt a large room layout, so that the building plane can be reasonably separated, flexible and convenient, and create an open house. The traditional structure (brick-concrete structure, concrete structure) restricts the freedom of space layout due to the material properties. In the past, the booths were usually 3.2 meters, 3.4 meters, and 3.6 meters. If it is too large, it will cause plate thickness, beam height, and column size. The phenomenon of "fat beam and fat column" appears, which not only affects the appearance, but also increases its own weight and increases the cost. Buyers often change the position of the wall by themselves during secondary decoration to increase hidden dangers.

2.Light weight, good seismic performance

The building floor of the same building area has a light weight steel structure. According to comparison, the weight of a six-story light steel structure house is only equivalent to that of a four-story brick-concrete structure house. Moreover, steel is ductile and can consume energy brought by earthquakes, so it has good seismic performance and high structural safety.

3.Convenient construction and short construction period

The structural components of Yansteel can be factory-manufactured and installed on site. Due to the small amount of work on the site, less pollution to the surrounding environment, at the same time, the degree of construction mechanization is high, and the construction speed is accelerated. According to statistics, the construction period of a steel structure of a building of the same area can be shortened by one third compared with that of a concrete structure, and the supporting material can be saved.

4.The comprehensive cost is low

Because of its light weight, reduced basic costs, reduced overall materials, reduced direct costs, short construction periods, and reduced indirect costs, the overall cost is low.

5. Meet the requirements of residential industrialization and sustainable development

The steel structure is suitable for large-scale production of factories, and has a high degree of industrialization. It can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows into a whole set of applications, integrate design, production, and construction, and improve the level of residential industrialization.

In summary, steel structure is suitable for innovative residential structure system. The steel structure can be designed with a variety of shapes, sizes, and spaces in accordance with different aesthetics and functional requirements. Manufacturers can complete with high precision, high quality, and high speed, so that the building can achieve both beautiful and economical results. With the development of high technology, people's concepts and lifestyles will also be continuously updated and changed, and the requirements for the overall quality of housing will continue to increase. For this reason, residential design must necessarily consider coordination and adaptation to these changing factors , And a new world of flexible design emerges. The steel structure is the most suitable structural system for the flexible design of the house.

When the resin drainage ditch is applied to the urban drainage system, if the color depth is different or the exchange capacity of the drainage is rapidly decreasing, the cleaning water is rising rapidly, and the water quality of the effluent is significantly deteriorated, then It can be judged that the resin drain is contaminated during use, and in order to solve the problem of contamination during the use of the product, the following reasons will be known.

1.The pollution caused by organic matter

Because the environment of professional resin drainage ditch is usually harsh, a large number of urban living polluted water sources will contain too much organic matter, and these organic substances can carry negative electricity in the water, becoming an anion,making it become the main substance that contaminate resin drain.Especially among these organic substances, may contain natural humic acid, organic impurities such as micelles, which adhere to the resin and occupy the active gene of the resin.Let it degrade the phenomenon of strong base active groups.Let it degrade the phenomenon of strong base active groups.

2.Suspended matter exceeds the standard

Secondly, when the resin drainage ditch is used, if there is too much suspended matter in the contaminated water, it will be tightly wrapped on the liquid film layer on the surface of the resin, so that the ion exchange process of the resin cannot be carried out normally. Let the resin drains have a certain impact during the course of use.

3.Excessive oil in contaminated water

Of course, no matter how powerful the resin drainage ditch is, it must not be able to compete with a large amount of oily substances in the polluted water. These oily substances will form a film on the surface of the resin drainage ditch, and even directly block the micro porous of the resin, hindering the normal operation of the resin drain.

In addition, when the resin drainage ditch is actually used, the contaminated water will contain bacteria, algae, amino acids, fluorine and other substances, which can also cause the resin drainage ditch to be polluted to varying degrees, and these pollution directly affect the comprehensive drainage. The ability to reduce the strength of its products in the process of use, increasing the burden of urban drainage systems, so be sure to avoid contamination when using.

Most of the components of resin concrete drainage ditch are taken from natural minerals such as quartz sand, basalt and granite.These grit as aggregates are screened and proportioned according to different sizes of particle, and mixed with synthetic resin used as cementing material,being produced new concrete with excellent properties.

Advantages of the product

The optimized raw material ratio and advanced production process make the resin concrete drainage product show excellent performance.
Bending strength: >22 N/mm2                           Pressure resistance: > 90 N/mm2                           Surface roughness: approx.25 μm
Modulus of elasticity: approx. 25 kN/mm2           Density: 2.1 -2.3 g/cm3
Water submerged erosion depth: 0 mm              Resistance to chemical attack: high

Weight of the product

The resin concrete drainage ditch has the advantages of high strength and light weight, and the weight of the member with the same pressure resistance level is significantly lower than that of the ordinary concrete, which makes the resin concrete member easier to manually operate during construction, and the cost is lowered.

Watertight performance

The water-inundation depth of the resin concrete drain is 0 mm, showing excellent water tightness and non-hydrophilic. The liquid falling on the surface does not penetrate and stay,decreasing the risk of the frost crack damage of the component.

Clean of the surface

The surface roughness of the resin concrete drainage ditch is small, and the smooth surface can quickly remove water and debris, which makes cleaning and maintenance work more convenient.

Chemical resistance

Resin concrete drainage ditch can effectively prevent a variety of aggressive chemical erosion without the need for additional protective layer. It can also be used for a long time under the complicated conditions of sewage composition.
