What to pay attention to after wearing clean clothes in a clean room
do you know? In addition to wearing dust-free antistatic clothing, shoes, and masks, people working in clean rooms must also slow down and handle lightly. Speaking of which, some people may not understand, why is this? There are three main reasons:
1.Friction electrification
Dust-free antistatic overalls can effectively prevent the accumulation of static electricity and introduce static electricity to the ground, but this cannot prevent the generation of static electricity. Many people know that friction will generate electricity, so if you walk or even run fast in a clean room, the soles will rub against the ground, which will cause static electricity.
Bring up the dust
It is understood that most domestic clean rooms are in the thousands, 10,000, or even 100,000 levels. Although the clean room is a relatively clean space, it still has dust particles. These dust particles are often attached to the ground, and some are relatively still in the air. When people walk, the bigger and faster the movement, the more dust particles on the ground will be driven to float in the air, while the movement of other limbs is too large and too fast, the relatively stationary dust particles in the air will float to the In the production of the product, it will affect the quality of the product and even cause harm.
3.Human comfort
I remember seeing a test: In a small, confined space, let a group of people exercise for five minutes. After five minutes, the indoor temperature was high by 6 ° C. It can be said that the temperature will increase with exercise. The dust-free clean room is also a similar enclosed space. Imagine if the operators are exercising vigorously, will this space become a hot and hot environment?
Combining these three points, we can realize that, from the perspective of products and personal comfort, it is not possible to walk and run quickly in a clean room.
