Clean room/clean room refers to the removal of particulates, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, air flow velocity and airflow distribution, noise vibration and Lighting, static control is within a certain range of requirements, and a specially designed room is given. The clean room is characterized by the fact that the external air conditions change, and the interior can maintain the characteristics of cleanliness, temperature, humidity and pressure that were originally set. The main function of the clean room is to control the cleanliness day and temperature and humidity of the atmosphere that the product is in contact with, so that the product can be produced and manufactured in a good environment space. This space is called (clean room/clean room). . The number of air exchanges in different grades of clean room: 100000 grade ≥ 15 times; 10000 grade ≥ 20 times; 1000 ≥ 30 times. Pressure difference: the main workshop is adjacent to the room ≥5Pa
Average wind speed: 10, 100 0.3-0.5 m/s; temperature >16 °C in winter; <26 °C in summer; ±2 °C in fluctuation. The temperature is 45-65%; the humidity of the GMP powder workshop is about 50%; the humidity in the electronic workshop is slightly higher to avoid static electricity.
Noise ≤65dB (A); fresh air replenishment is 10%-30% of total air supply; illumination 300LX
Air flow → initial effect purification → air conditioning → medium efficiency purification → fan air supply → pipeline → high efficiency purification air outlet → blowing into the room → taking away particles such as dust bacteria → returning blinds → initial effect purification Repeat the above process to achieve purification purposes.
