Purification engineering principle of electronics factory
Air flow - primary air purification - air conditioning - secondary air purification - fan supply - air duct - efficient air purifier - air into the room - dust - carrying bacteria
The above process can be repeated by the granule - the return air louver - the primary effluent purification.
Purification engineering parameters of electronics factory
Ventilation rate: 100,000 or more than 15 times; 10000 is greater than or equal to 20 times; 30 1000 or greater. Pressure difference: the main workshop is equal to more than 5Pa for adjacent rooms
Average wind speed: level 10, level 100 0.3-0.5m/s; Temperature 16 ℃; winter > Summer < 26 ℃; Fluctuation plus or minus 2 ℃.
Temperature: 45-65%; GMP powder workshop humidity should be around 50%; The humidity in the electronics workshop is slightly higher to avoid static electricity.
Noise is less than or equal to 65dB (A); The fresh air supplement is 10%-30% of the total air supply. Illumination 300 lx.
Purification engineering structure material of electronics factory
1. The purification workshop walls and roof plates of electronics factory are mostly made of 50mm color sandwich steel plate, which is characterized by beauty and strong rigidity. Arc wall Angle, doors, window frames and other general use of special aluminum oxide profile manufacturing.
2. The ground of the electronics factory can adopt epoxy self-current floor or high-class wear-resistant plastic floor.
3. Made of hot-cross zinc plate for the return air pipe of the electronics factory, put on the flame-retardant PF foam plastic plate with good purification and heat preservation effect.
4. The efficient air supply port of the electronics factory is made of stainless steel frame, beautiful and clean; the perforated screen is made of painted aluminum plate, free from rust and dust, and suitable for cleaning.
