没有了！ Development and influence factors of vacuum coating UV prime
The so-called vacuum coating is to place the material to be plated and the substrate to be plated in the vacuum chamber. A certain method is adopted to heat the material to be plated, to vaporize or sublimate it, and to process the film on the surface of the plated substrate by fly sputtering. In the condition of vacuum film can reduce the collision of atoms and molecules to the substrate material in the evaporation process in the molecule, reduce the chemical reactivity of the molecules in a gas and steam source between materials (such as oxidation), and reduce gas molecules in membrane process into the films become the amount of impurities, so as to provide film the density and purity, deposition rate and adhesion with the substrate. Generally, vacuum evaporation requires that the pressure in the film is equal to or lower than 10-2Pa. The pressure is lower when the evaporation source is far away from the substrate and the quality of the film is very high.
