What are the consequences of static electricity in a clean room
Clean room refers to the removal of particles, harmful air, bacteria and other pollutants in the air within a certain space, and the indoor temperature, cleanliness, indoor pressure, air velocity and air distribution, noise vibration and lighting, static control Within a certain range of needs, and given a specially designed room. That is to say, no matter how the external air conditions change, the indoor can maintain the characteristics of the cleanliness, temperature, humidity and pressure required by the original settings.
According to international practice, the dust-free purification level is mainly based on the number of particles per cubic meter of air whose particle diameter is greater than the classification standard. In other words, the so-called dust-free is not 100% without a little dust, but controlled in a very small amount of units. Of course, the particles that meet the dust standard in this standard are already very small compared to our common dust, but for the optical structure, even a little bit of dust will have a very large negative impact, so in the production of optical structure products , Dust-free is an inevitable requirement. Electrostatic charge will adsorb tiny particles in the air, the main ways come from:
1) Dust generation: Dust generation mainly comes from people, accounting for about 90%. The dust generated during the transportation of products, materials, etc. is generally very small compared to the amount of human dust, which can be ignored.
2) Bacterial germs: Pollution caused by staff, hair, skin, clothes will be contaminated with bacteria.
The anti-static products used in the clean room are as follows:
1. Dust-free workshop consumables: dust-free cloth, dust-free paper, non-woven masks, dust-free gloves. dust-free finger covers, shoe covers, clean cotton swabs, sticky pads, sticky rollers, purifier pens, purifiers This, clean copy paper, clean room vacuum cleaner.
2. Air filter: primary effect filter, primary effect plate filter, primary effect dense pleated filter, primary effect bag filter, intermediate effect filter, intermediate effect bag filter, intermediate efficiency filter with separator Filter, plate-type medium-efficiency filter, V-shaped large-volume medium-efficiency filter, high-efficiency filter, high-efficiency filter without partition, high-efficiency filter with partition, high-efficiency filter with large airflow, chemical filter, cylindrical filter, filter sponge.
3. Anti-static products: anti-static curtains, anti-static table mats, anti-static clothing, anti-static shoes, anti-static dust-free masks, anti-static gloves, anti-static wrist straps, anti-static turnover boxes, anti-static bags, anti-static chairs , Anti-static brush, anti-static tweezers, anti-static tester
