Plasma cleaning before glass coating

In the process of glass manufacturing, there are often oil, wax, fingerprints, grease and other organic pollutants on the surface. The existence of these residual pollutants is not conducive to coating, spraying, printing, bonding, welding and other processes. Therefore, before the next step, these pollutants need to be cleaned to ensure the subsequent process quality.

Plasma cleaning in AF, AS, AG, AR coating (spraying) process before fine cleaning, etching and activation of the substrate surface, can get a very thin high tension coating surface, is conducive to the adhesion of the spraying potion firm and uniform thickness.

1. Cleaning: Remove organic matter, resin, dust, oil, impurities and so on from the surface to increase the surface energy

2. Etching: the surface of the material is modified and coarsened. After etching, the protruding objects on the surface increase and the surface area increases

3. Activation: the introduction of oxygen containing polar groups, such as hydroxyl and carboxyl and other active molecules
