Pass all sorts of establishment of project technology respect and rigorous management, make content of indoor small particle, air current, pressure also control inside certain limits, space of this kind of room weighs clean room.
2, of clean technology apply
1 microelectronics industry
Microelectronics industry is current highest to clean room demand industry is clean course of study. In addition, the production that if modern industry is medium liquid crystal, fiber-optic,waits, all have likewise clean spent requirement.
2 medicine industry
(1) of drug production our country " drug production management is normative " (weigh GMP again) already carried out inside countrywide limits, put forward to ask at the different and clean level of process accordingly to producing an environment. Besides the size of particle of the dust in demarcate air and content, opposite content particle (the bacterium is counted) also have clear limitation.
(2) ward of the remedial room of hospital leukaemia, burn, surgical surgery, prevent the bacterial infection in air according to the condition with corresponding clean technology, ensure action to the environment arriving since cure.
(3) medical science experiment to experimental animal raise, the course test project such as genetic engineering, also should have clean environment, ability obtains significant gain.
The asepsis of 3 food is packed, in maintain the food quality, respect such as sweet, flavour, nutrition also the canister with antiseptic high temperature of be superior to installs food.
4 other, if space navigation industry, nicety is mechanical industry, instrument bearing industry, careful chemical industry, use clean technology.
3, the sort of the contaminant in air?
1, bacterium
This one term included the bacterium to be comprised by thousands of kinds of monad one big microbial kind group. The bacterium is nowhere is absent: Air medium, water medium, soil is medium, vivid or outside body is being reached inside dead more advanced organism. Bacterium already in consist in surroundings, also inside consist in human body. The bacterium is clean room prevailing is microbial contaminant.
2, alga
Alga with its he differs microbially at at, it can undertake photosynthesis. Alga is controlled in pollution and clean room is not a problem commonly, but the recycle system to resembling water, alga causes an influence possibly.
3, true fungus
In contaminative control and clean room domain, fungus is source of the 2nd big microbial pollution, can become a kind of serious menace. Fungus and most bacterium photograph are compared, simpler to the requirement of nutrient, can be below the condition that does not have a large number of water grow. Microzyme becomes the contaminant in polluting control and clean room rarely. But, they may go up in certain carbohydrate and grow on the product with water high content.
