Clean room, also known as clean room or clean room. It is the basis of pollution control. Without a clean room, it is impossible to produce sensitive components on a large scale. In fed-std-2, a clean room is defined as a room with air filtration, distribution, optimization, building materials and installation, in which specific adjustment procedures are used to control the concentration of aerosols in the air in order to achieve an appropriate level of particle cleanliness. Dust-free room is a specially designed room that removes particulate matter, harmful air, bacteria and other pollutants in the air in a certain space, and controls indoor temperature, cleanliness, indoor pressure, airflow velocity and distribution, noise, vibration, lighting, static electricity and other pollutants within a certain range of requirements.
There are different types of cleanrooms in different industries, such as industrial Cleanrooms and biological cleanrooms.
Industrial Cleaning Room:
The control object of inanimate particles in industrial clean room. Clean shed mainly controls the pollution of dust particles in the air to work objects, usually maintaining positive pressure. Applicable to precision machinery industry, electronic industry, semiconductor, integrated circuit, etc.) aerospace industry, high-purity magnetic products, atomic energy industry, chemical industry, light industry (CD, tape, film production), LCD (liquid crystal glass), computer hard disk head production and other industries.
Biological clean rooms mainly control the pollution of living particles (bacteria) and non-living particles (dust). The working objects can be divided into: 1. General biological cleanroom: Mainly control contaminated microorganisms (bacteria). At the same time, its internal materials need to be able to withstand the erosion of various fungicides, and the internal pressure is generally guaranteed. Its internal materials can essentially withstand the disinfection treatment of various industrial cleanrooms. Food, cosmetics, beverage production, animal laboratories, physical and chemical laboratories, blood stations, etc. Biosafety Cleaning Room: The main control object of particle pollution and the external and human life. Internal maintenance and negative pressure atmosphere. Examples: Bacteriology Laboratory, Physical Engineering, Biology.
