Application of clean technology
Clean technology has experienced more than half a century, and its application range is increasingly wide, and technical requirements are more complicated. Currently, its representative application is the microelectronics industry, medical and health and electronic industries. Its application area is:
01. Microelectronics industry
02. Semiconductor manufacturing
03. Pharmaceutical industry
04. Optical Industry
05. Biotechnology Industry
06. Pure chemical reagent manufacturing
07. Micromechanical processing industry
08. Hospitals and other health care organizations
09. Production and packaging industry of medical devices and transplanted devices
10. Food & Beverage Industry
The microelectronics industry is currently the highest in the clean room. The development of large-scale and large-scale integrated circuits (LSI, VLSI) is increasingly high. In the integrated circuit manufacturing process, the larger the integration, the finer graphics size (represented by line width), the smaller the size of the cleansing chamber control particle size (usually 1/10 of the line width), and the dust The lower the requirements. In addition, the production of liquid crystals, fibers, etc. in modern industries also has a cleanliness requirement.
2. Medical industry
1) Drug production my country's \"Pharmaceutical Production Management Specification\" (also known as GMP) has been implemented nationwide, and the requirements for different clean levels have been put forward in the corresponding process and production environment. Clean areas and control zones have been developed for the production, filling of powder, powder, needles, tablets, large infusion production, filling. In addition to defining the size and content of dust particles in the air, there is also a clear limit on bio-particles (bacteria).
2) Hospital leukemia treatment room, burn ward, surgery room, must also use air clean technology according to specific conditions to prevent bacterial infection in the air, and control the treatment environment.
In genetic engineering, drugs and pathological inspections, biomogenesis, national defense scientific research, often need to operate in a sterile dust-free environment, on the one hand, ask the test piece from being contaminated by its microbial contamination, on the other hand, the material is required. Such as tumor viruses, high-risk pathogens, radioactive substances, etc., such as radioactive materials, etc., harmful operators' health and pollution. For such experimental operations, it is generally required to isolate two levels. The first-level common biosafety wrap cabinet isolates the staff and pathogens; the second level is to isolate the experimental work area with other environment. This type of laboratory is different from the general laboratory, which is in a negative pressure state.
Air clean technology is also widely used in biological experiments, food processing, aerospace, precision machinery, instrumentation, fine chemistry and other industries.
