Second, the principle of operating room purification. Clean room is the equipment adopting HEPA and air environment purification technology, and its dust collection rate is as high as 99.97 ~ 99.99995%, so the air that needs to be filtered by this filter can be said to be very simple and clean. However, in a clean interior design, besides people, there are also dust sources such as machines. Once the dust in these problems spreads, it cannot be kept in a clean space. Therefore, enterprises must make full use of different airflow to discharge dust outdoors quickly and in time.
Three dusts in clean room of operating room. Clean room has three principles: dust-free, dust-free and dust-free. As one of the buffer channels to enter the clean room, the air shower room is one of the best cleaning equipment to control dust.
Clean room decoration
The two doors of the air shower room are interlocked and can be used as an air lock room to prevent polluted and unpurified air from entering the clean area.
Fourth, the main function of operating room purification Z is to control the cleanliness and temperature and humidity of the atmosphere contacted by technical products (such as silicon wafers), so that product enterprises can manufacture in such a good environment development space, which we can call a clean room. According to China's international trade practice, the level of dust-free purification is mainly determined by students according to the number of particles with a particle size larger than the division management standard per cubic meter of air. That is to say, the so-called dust-free, not 100% without its own dust, but should be controlled in a very important and trace unit design in a country. Of course, the particles that meet the dust standard in this industry standard are very small compared with the common dust in our life now. However, for some domestic optical structures, even a little dust will lead to very big negative factors, so dust-free is an inevitable requirement for the production of optical structure products.
5. The number of dust particles with a particle size less than 0.5 micron per cubic meter can be controlled below 3,500, which has reached the first class A of China international dust-free standard. At present, it is mainly used for the clean standard management of chip-level production and processing, which requires students to be above grade A. Such high standards are mainly used for the production of control chips with higher social level. The amount of dust is strictly controlled within 1000 per cubic meter, which is also commonly known as 1K in the industry.
