Treatment of gaps between clean room doors and windows:Generally speaking, clean room doors and windows have three types of structural gaps. The first type is the assembly and splicing gap between the door and the clean room door opening; the second type is the overlap gap between the door and the opening fan; the third type is the installation gap between the glass or other core boards. Generally speaking, the air leakage of the clean room door is nothing more than the problem caused by the above-mentioned three kinds of gaps. Among the three structural gaps, the first and third types are fixed gaps, and the second type is movable gaps. 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. Treatment of fixed gaps:The installed gaps examined are not only relatively small in the number of doors and windows in each clean room today, 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 airtight clean room doors and windows, but also for the general clean room door structure. Due to the strong 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. Basically ensure the air tightness of this type of gap; the second type of fixed gap is the installation gap of glass or other core boards. The number of gaps in the door of an orange clean room is relatively small, but the structural gaps in the one chamber are often the main part. Especially for the outer universe, they are exposed to the atmosphere and affected by the outdoor climate. It must be handled carefully. On the one hand, it is necessary to minimize the installation gap of the core strip glass, and on the other hand, it is necessary to carefully choose the fortification structure. Handle the movement gap:How to overlap the opening fan and frame material of the clean room door is the key to the design of the clean room door seal. The gap at the lap joint is different from the fixed gap. Because the movable fan needs to be opened, the wood can take 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 in 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 gap around the door ...

The concentration of suspended particles in the clean room is controlled, and its construction and use method is to minimize the particles that enter, produce, and stay in the room; other indoor parameters, such as temperature, humidity, and air pressure, are controlled as needed. The first half of the definition basically describes what is clean, which is a room that minimizes the entry, generation, and retention of particles. To achieve this, first, a very large amount of supply air must be filtered through a high-efficiency filter. The purpose of this air supply is: (1)Dilute and remove particles and bacteria emitted by indoor personnel and equipment; (2) Pressurize the room to ensure that dirty air does not flow into the clean room. Secondly, the building materials of the clean room do not produce particles and are easy to clean. Finally, clean room personnel use clothing to cover their bodies to minimize the particles and microorganisms they emit. These measures and other similar measures to minimize the pollution introduced, generated, and retained using clean rooms. The clean room can also control temperature, humidity, sound, lighting, and vibration. But these characteristics are not exclusive to clean rooms. The clean room is a modern thing. Although the source of clean room design and management can be traced back to anti-infection measures in hospitals more than 100 years ago. However, the demand for a clean environment in the manufacturing industry was only put forward in modern society. The reason why the manufacturing industry needs a clean room is because people, production equipment, and buildings all produce pollution. As explained, people and equipment can produce millions of particles, and general building materials are also easily broken. But the clean room can control the spread of particles, so that the production can be carried out in a clean environment. We are clean room equipment manufacturers.Welcome inquiry.
Since the Spring Festival, the whole country has been shrouded in the heavy atmosphere brought by the new coronavirus pneumonia. Wuhan is closed and new cases have appeared in other parts of the country. Viruses are raging, touching people, preventing and controlling epidemics. The medical industry is always at the forefront. As the upstream industry of the medical industry, the clean room industry has also stepped onto the battlefield of epidemic prevention. The clean room industry mainly serves the design and construction of wards, laboratories, testing rooms, and operating rooms in the medical system. This article will discuss how the clean isolation ward plays a role in the prevention of epidemic viruses in the case of this new coronavirus. First, we must clarify the concept of isolation wards and general clean room wards. Isolation ward refers to a ward that gathers patients diagnosed with infectious diseases and uses physical measures to isolate them from other patients, thereby preventing pathogenic microorganisms from spreading through the air and protecting uninfected people from the threat of air pollution. Compared with ordinary wards, isolation wards have more guarantees in terms of manpower, material resources and technology to ensure good and timely treatment of patients diagnosed with infectious diseases. 1. Strict zoning. The clean area, semi-contaminated area, and contaminated area of the infectious isolation ward are strictly partitioned and rationally arranged. A contaminated area is an area where there are patients or patient secretions, such as wards, toilets, bathrooms, toilets, and dirt clothes storage. The clean area refers to the area without the above pollution, such as the warehouse, pharmacy, sterilization room and duty room in the isolation area. The semi-polluted zone refers to the transition zone between the two, such as buffer rooms, isolation corridors, and preparation rooms. The three areas are well divided and have clear isolation signs and functional attributes. After this step is completed, the air will not be cross-contaminated by technology, equipment, personnel control, etc. 2. Differential pressure control. Air flows from a high place to a low place. After the functional zoning of the isolation zone is planned, the pressure difference control is done to effectively prevent the air in the isolation ward from flowing out of the isolation zone. According to the air pressure difference between the isolation room and the neighboring room or outside, the isolation ward can be classified as follows: Class S (standard pressure difference): used for isolation through contact transmission and mouth foam transmission. Type N (negative pressure difference): used for isolation of airborne diseases. Type P (positive pressure difference): used for isolation of patients with low immunity, such as: organ transplant patients As we all know, this new coronavirus is spread by mouth-foam transmission and contact transmission. ...

The electronics industry's requirements for clean rooms in cleanrooms need to be equipped with air showers, clean sheds, FFU purification units, high-efficiency filters, high-efficiency air outlets, and transfer windows. Your requirements are up to standard if these equipments are not equipped. The electronics industry's requirements for clean rooms in clean rooms: clean rooms are also called clean workshops, clean rooms, clean rooms. There are many types of production processes in electronics factories, and integrated circuit production (divided into photomasks, front processes, and rear processes) Process), Pingnan display production (divided into LCD, PDP, TFT, VFD, picture tube), silicon material production (monocrystalline silicon, polysilicon), optical fiber production, card manufacturing, surface mount (SMT), separation device production ( Power first, second and third level tubes, capacitors, resistors), complete machine assembly production (set-top box, digital projector, electronic digital camera), automatic control component production (sensors, actuators), etc. Due to the variety of production processes, the requirements for cleanliness levels are different, high is high, and low is low; the requirements for particle size control are also different, ranging from about 0.1 to 5um; the requirements for temperature and humidity control are relatively high For example, the previous steps of integrated circuits generally require a base temperature of 22 ° C (accuracy ± 0.1 to ± 1 ° C) and a relative humidity base of 40% (accuracy ± 2 to ± 5 ° C; the gradient level required for positive pressure values is The degree of cleanliness changes from high to low, the difference is 5 ~ 10Pa. The cooling load of the dust-free workshop in the electronics industry is much larger than that in other industries, and the unit cooling load is 400 ~ 500W / ㎡. Due to the large cooling load, cooling is also generally required in winter, which is a characteristic of the electronics industry. There are many types of harmful gases generated in the production process of the electronics industry, and the quantities are also large, so the amount of exhaust air and fresh air required is also large. The energy saving measures of new exhaust air are also one of the industry's characteristics. Before discharge, treatment should be done to make the exhaust air load environmentally friendly. The production process of the electronics industry requires antistatic and anti-vibration requirements, and there are many types of bulk gases and special gases, which require high purity and cleanliness: 1. Noise level (empty state) of 10,000-level clean room in electronics factory: should not be greater than 65dB (A) 2. The clean room in the electronics factory's clean room should not be less than 60% full, and the horizontal unidirectional flow clean room should not be less than 40%, otherwise it will be a partial unidirectional flow. 3. The static pressure difference between the ...
