Tairong the electronic industry clean room engineering

Electronic clean room construction materials: 1, purification plant wall, the top sheet generally use more steel plate 50mm thick sandwich of color, which is characterized by beautiful, strong rigidity. Arc corner, doors, window frames and other general uses special aluminum oxide manufacture. 2, the ground floor can be used epoxy floor gravity or advanced wear-resistant plastic flooring, anti-static requirements, the choice of anti-static type. 3, return air duct made of hot galvanized plate, affixed purifying effect of a good fire-retardant insulation foam plastic plate PF. 4, HEPA stainless steel frame, beautiful and clean, perforated metal mesh plate with aluminum paint, no rust dust free, appropriate cleaning. Electronic clean room clean parameters: ventilation frequency: 100 000 ≥15 times; 10000 ≥20 times; 1000 ≥30 times. Pressure: the main workshop adjacent room ≥5Pa. Average wind speed: 10, 100 0.3-0.5m / s; winter temperatures> 16 ℃; summer <26 ℃; fluctuation ± 2 ℃. Humidity 45-65%; GMP powder workshop humidity around 50% is appropriate; electronic workshop slightly higher humidity to avoid static electricity. Noise ≤65dB (A). Fresh air replenishment is 10% -30% of the total air volume; illumination 300LX. Electronic clean room design: For conventional electronic factory clean room air-conditioning design, should be based on the production process requirements and economic conditions Party to choose which electronic factory air-conditioning design programs to meet production requirements as a prerequisite. Based on past experience, for demanding air conditioning program can choose to focus on air handling units; for less demanding, but also a low initial investment, you can choose Guiji + FFU. In short, the specific program selected according to specific circumstances.
