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.
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 ...

Clean air-conditioning technology is also called clean room technology. The definition of clean room: In addition to meeting the general requirements for temperature and humidity in air-conditioned rooms, through various facilities and strict management in engineering technology, the indoor particulate content, air flow, pressure, etc. are also controlled to a certain range. Inside, this particular space is called a clean room. Typical application areas of clean air-conditioning technology include: microelectronics industry, pharmaceutical industry, food industry, etc. 1) Microelectronics industry The microelectronics industry is currently the industry with the highest requirements for clean rooms. The production and development of large-scale and ultra-large-scale integrated circuits (LSI and LSI) and liquid crystal displays (LCD) have increasingly higher requirements for dust control. In addition, modern industry In the production of liquid crystal and optical fiber, there are also high requirements for cleanliness. 2) Pharmaceutical industry Pharmaceutical production: The National "GMP" sets different requirements for the cleanliness of the pharmaceutical production environment. For the preparation of bulk drugs, powders, injections, tablets, large infusion production, filling and other processes, clean standards for clean areas and control areas have been formulated. Hospitals: Leukemia treatment rooms, burn wards, prevention of acute infectious diseases, and surgical operating rooms must also adopt clean technologies according to specific conditions to prevent bacterial infections in the air and play an environmental protection role in treatment. Medical scientific experiments: For the scientific scientific experimental processes such as breeding of experimental animals and genetic engineering, a clean environment is also required to obtain effective results. 3) Food industry Food aseptic packaging (such as flexible packaging of fresh fruit juice, milk, etc.) needs to complete the packaging process in a clean environment. 4) other Such as aerospace industry, precision machinery industry, instrumentation industry, fine chemical industry, etc., all have widely applied clean technology.
Clean workshops are generally closed, with few doors and windows. In the event of a fire, the heat of the flue gas is not easy to radiate outward, resulting in the retention of flue gas, a sharp increase in heat, and more likely to cause injuries and deaths due to high temperature and hypoxia. Therefore, it is important to take fire safety measures. Clean workshop Note 1: In the decoration of clean workshops, we must pay attention to the combustion performance of the decoration materials and minimize the use of some polymer synthetic materials to avoid the generation of a large amount of smoke during the fire, which is not conducive to escape. Note 2: Strict requirements are imposed on the electrical pipelines, and steel pipes should be used wherever possible to ensure that electrical circuits do not become a way for fire to spread. Note 3: Keep the environment clean in the clean workshop. Keep all materials neat and away from heat sources. Pay attention to indoor ventilation. At the same time, ensure that the fire prevention passage in the workshop is unblocked. No items are allowed to be placed at the exits and walkways. Note 4: In the clean workshop, it is not allowed to privately pull the power and wires. If it is really needed, it must be reported to the manager of the production department for approval. It should be handled by the power equipment room and removed in time after use. Note 5: During the operation of oil-fired boilers, inspections should be strengthened, and abnormalities should be handled in time. Note 6: Avoid all kinds of electrical equipment and lines from being wet and overloaded to prevent short circuits from causing accidents. The use of various equipment must strictly abide by the operating regulations, and illegal operations are strictly prohibited. Note 7: The use of open flames is prohibited in clean workshops. If it is really necessary, the consent of the Security Department must be obtained, and it can only be used after effective security measures have been taken. Special persons shall be responsible during the use, and ensure that it is handled properly without hidden dangers after use. Note 8: The clean workshop should be equipped with a gas alarm device, and a gas detector should be installed in the storage and use place. When the gas alarm sends out an alarm signal, it should immediately cut off the supply source, issue an alarm to the site staff, and open the exhaust equipment to exhaust air.
