100,000 cleanroom standards are clean room the number of air changes .
1, 100,000 clean room air change times not less than 15 times / h.
2, 10,000 clean room air change times not less than 25 times / h.
3, 1,000 clean room air change times not less than 50 times / h.
10,000 level purification, mainly by the clean air flow constantly dilute the indoor air, will be indoor pollution gradually Discharge, to realize the clean effect.
Physical purification:
1, adsorptive filtration-activated carbonActivated carbon is a kind of porous charcoal-containing material, which has highly developed pore structure. The porous structure of the activated carbon provides a large amount of surface area, which can be fully contacted with the gas (impurities), thus giving the activated carbon the unique adsorption properties, making it very easy to achieve the purpose of absorbing and collecting impurities. Like magnetism, all molecules have a mutual gravitational attraction to each other.
2, mechanical filtration - HEPA mesh?HEPA, meaning high-efficiency air filter, to achieve the HEPA standard filter, for 0.3 micron efficiency of 99.998%, HEPA mesh is characterized by the air can be passed, but fine particles can not be passed.HEPA filters are composed of a stack of continuous before and after the folding of the sub-glass fiber membrane to form a wave-shaped Gaskets are used to place and support the filter boundary mass.
