1. Overview of glass coating technology
Glass coating technology is a process of depositing thin film materials on the surface of glass to meet different application requirements by changing the optical, thermal and electrical properties of glass. Glass coating technology is widely used in architecture, automobiles, optical instruments, electronic equipment and other fields, which plays a vital role in improving the functionality and aesthetics of products.
2. operation steps of glass coating technology
2.1 surface treatment
before glass coating, the glass surface needs to be treated first to ensure that the film can be firmly attached. Common surface treatment methods include mechanical grinding, chemical corrosion and plasma treatment.
2.2 thin film deposition
thin film deposition is the core step of glass coating technology. The common thin film deposition methods are physical vapor deposition (PVD) and chemical vapor deposition (CVD).
2.3 thin film modulation
The purpose of thin film modulation is to change the optical properties of thin films. Common methods include multilayer film structure design, doping and controlling deposition rate.
2.4 surface treatment
after the film is deposited, the glass surface needs to be treated to improve the wear resistance and corrosion resistance of the film. Common surface treatment methods include heat treatment, ion implantation and sputtering.
