Clean clothes and shoes must be static after cleaning
Dust-free suits and dust-free shoes used in dust-free workshops must be professionally cleaned and cleaned before they can be recycled in a clean environment in a clean room.
As the production requirements for dust-free environments are getting higher and higher, the factory attaches great importance to the dust-receiving rate of cleaned dust-free coveralls and dust-free shoes. After each cleaning, it will require dust-free coveralls and dust-free. The dust rate of the shoes is tested. However, some factories have ignored the anti-static test of jumpsuits and shoes.
In fact, this still has a lot of hidden dangers. Imagine that if a dust-free coverall and shoes have poor anti-static performance, even if the dusting rate is qualified, a large electrostatic voltage will be generated during wearing and use, which is a great safety hazard for some sensitive devices. It is very likely to cause fatal damage to the final product quality. In addition, a large electrostatic voltage can absorb dust and cause great damage to the clean environment of the clean room. Therefore, dust-free coveralls and shoes after dust-free cleaning must be tested periodically for static parameters.
