After the vacuum coating machine has been used for a long time, it should be cleaned regularly. Why? What problems will occur if you do not clean often?
Before coating process, simple surface cleaning of the coating material can prolong the service life of the coating machine, because various pollutants not only impede the obtaining of required vacuum degree of the vacuum system, but also affect the strength and sealing performance of connection of the vacuum parts.
Common contaminants in vacuum coating machines are:
1. Grease includes the lubricants, cutting fluids, vacuum greases, etc. that are contaminated during processing, assembly, and operation.
2. Hand sweat during operation, water vapor and saliva when blowing, etc., residual substances in the cleaning of acid, alkali and salt substances, hand sweat, minerals in water, etc., and polishing residue, ambient air dust and other organic matter.
The purpose of cleaning these contaminants is to improve the working stability of the vacuum coating machine and make the coating work smoother.
