Glass coating is a kind of chemical polymer material. Because of its high-density chemical properties, it is used in the field of car beauty. At the same time, glass coating has the characteristics of high gloss, anti-oxidation, acid and alkali resistance, and anti-ultraviolet rays. After being used to coat the paint surface, the gloss of the paint surface is very good, and the paint surface is isolated from the outside world, which has a good protective effect.
The main production process of coated glass
1. Chemical vapor deposition method
Chemical vapor deposition is a process technology in which one or several compounds or elemental gases containing film elements are supplied to the substrate, and the required solid film is deposited on the surface of the substrate by gas-phase reaction. This technology has become the production of coated glass. The main preparation technology. Online CVD coating technology is a CVD process technology for continuously depositing compound films in the production process of float glass. It is currently the world's most advanced coating glass production technology.
2. Vacuum evaporation method
Vacuum evaporation coating method refers to the use of high temperature heating evaporation material (metal alloy or metal oxide) to a certain temperature under certain vacuum conditions, so that atoms or molecules vaporize and escape from the surface to form a vapor stream and fly Sputtering on the surface of the glass substrate to condense to form a solid thin film.
3. Solid powder spraying method
The spray coating technology is a process in which one or more reactive gases or atomized particles with a solution of a metal salt compound or a powder of a metal salt are sprayed on the surface of the hot glass to form a film by thermal decomposition. The solid powder spraying method is a coating method applied to the float production line by Ford Motor Company of the United States in the early 1980s, and the process flow of the solid powder spraying method.
