(Summary description)
100000 clean workshop, as the name suggests, generally speaking, the production environment of the workshop should be very clean and tidy, which is the most basic element for general production plants. Below, we will introduce 100000 clean workshop in detail.
The whole vehicle room is clean and clean with complete electrostatic protection. It is equipped with central air conditioning in the whole workshop to control the cleanliness, temperature and humidity of the air contacted by the products, so that the patches can be produced, manufactured and tested in a good environment space, so as to improve the product quality.
However, since it is called a 100000 level clean workshop, the environmental parameters of the workshop must be strictly controlled
The first is the temperature and humidity control of the workshop. The temperature range is generally controlled between 18 ℃ and 28 ℃, and the humidity range is between 40% and 85%.
The second is the workshop air discharge and ventilation frequency. Fresh air volume ≥ 30 m3 / h / person, ventilation frequency ≥ 15 times / h.
Third, static pressure difference. Static pressure difference ≥ 5pa, static pressure difference ≥ 10Pa.
Fourth, the maximum allowable number of dust particles. ① 5 μ M: 3500000; ② ≥ 5 μ M: 20000.
Fifth, the number of floating / settling bacteria. ① The number of planktonic bacteria: ≤ 500 / m3; ② the number of settling bacteria: ≤ 10 / m3;
The last one is the test method. According to the implementation regulations of code for construction and acceptance of clean room (GB 50591-2010), check whether it meets the relevant national standards.
