Talk about the wall standard of the purification project and its purification principle and other knowledge

Jun 20, 2019

First of all, regarding the wall standard of purification engineering, we should pay attention to the five average values of its multiple detection, that is, it will be less than three times, or, for the three benzene series, when it is less than three times, use the wall product MA. In the implementation of purification project, if the average value of five items tested is more than three times but not more than five times, we should pay attention to the use of wall product YA.

 

Next, we should pay attention to the fact that when implementing the purification project, the average value of five items detected is more than five times, or any one of the benzene series is more than five times, or because the wall decoration is carried out in wallpaper environment, we will use YAB.

 

Next, when we talk about the purification principle of the purification project, we should pay attention to it, including the 10,000-class dust-free workshop and its purification project, and the number of air exchange in its clean room, which is about 30 times per hour. In terms of the workshop temperature, the requirement is 23 degrees plus or minus 2 degrees, and the humidity requirement is 40% - 60%. Then, the dilution principle of air will be used to filter indoor air continuously, so that in fact, the number of particles that can reach more than 0.5 microns will be less than 350/liter.

 

Including 10,000-class dust-free workshop and its purification engineering and cleaning room purification principle, first is air flow, then primary purification air conditioning intermediate purification, then, the use of fans for air supply pipeline high-efficiency purification vent, which will be blown into the room dust bacteria and other particles return air shutter primary effect purification, so repeat the above. Cheng, will be able to achieve the purpose of purification.

 

Finally, we should pay attention to the purification of Engineering floors, which generally use epoxy self-flow floor or high-grade wear-resistant plastic floors. There are certain anti-static requirements in the purification project. In fact, we can choose anti-static type, specific, that is, to determine the actual situation.www.wxrfcleanroom.com
