Cleanroom classification
Dust-free cleanroom can be divided into the following levels:
1. Level 1. The level 1 dust-free room is mainly suitable for the microelectronics industry where integrated circuits are made. The precision requirement for integrated circuits is sub-micron.
2. Level 10. Class 10 cleanroom is mainly used in semiconductor industry with bandwidth less than two microns.
3. Grade 100. Class 100 cleanroom are commonly used in the medical industry for aseptic processes such as surgery, including transplantation, synthesizer manufacturing, and isolation of patients susceptible to bacterial infections, such as bone marrow transplant patients after isolation
Heal.
4. Thousand level. Thousands of cleanroom is mainly used for the production of dry high-quality optical products, and for the installation of testing, installation of aircraft snake instrument, installation of high quality micro bearings, etc
5. Class ten thousand. Ten thousand cleanroom mainly uses the installation of dry hydraulic equipment or pneumatic equipment, but also can be used in the dry food and beverage industry, in addition, ten thousand cleanroom is also very commonly used in the medical industry
Class of 600, 000. One hundred thousand grade cleanroom is mostly used in industrial sectors, such as the production of optical goods, the production of large electronic systems, hydraulic or pneumatic systems for smaller components, the production of food and beverage, and the pharmaceutical industry often uses this grade of cleanroom.
Two, dust-free clean rate design requirements
1. Select the appropriate environment and construction area. Cleanroom should be built in areas with appropriate temperature and humidity and good ventilation effect as far as possible, and the ground should be kept level as far as possible.
2 Choose reasonable supporting clean equipment, the entrance of the fine air shower room, the flow of dust and personnel carried by the dust effectively removed, the double door interlock to form a closed space, to prevent dust and other wine floating objects from the air shower door into the clean area
3, choose reasonable air purification ventilation equipment, according to the cleanliness level of the cleanroom, reasonable planning of air conditioning purification and air intake and exhaust system, to ensure the stability of positive and negative pressure value in the clean rate, to ensure the proportion of internal fresh air.
4 Choose live building materials, according to different needs, such as to adapt to strong alkali and acid abrasion resistance scratch, etc., the transfer window equipped with stainless steel optional material, mechanical co-marketing control, with sterilization
