Clean the vacuum coating machine

Before proceeding with the vacuum technology should be vacuum cleaning materials, material surface to remove pollutants from the artifacts or system; Light coating machine parts surface cleaning processing also is very be necessary, because caused by pollutant gas, steam source will not only make the vacuum system cannot obtain the required degree of vacuum. And because of the existence of pollutants at the same t...ime can also affect the strength of the joint vacuum components and sealing performance.
Pollutants can be defined as "any kind of useless matter or energy, multi arc ion coating machine according to the physical state of pollutants can be divided into solid, gas and liquid, they exist in membrane or grain form. The chemical characteristics, it can be in ionic or covalent states, can be inorganic or organic matter.
Exposed to the surface the most vulnerable to pollution in the air, there are many sources of pollution, the original pollution is usually part of the process of forming surface itself. Phenomenon of adsorption, chemical reaction, leaching and drying process, mechanical processing and diffusion and segregation are increase the components of surface contaminants.
