Sandblasting process in sandblasted glass
Sandblasting glass is a process that uses compressed air as a power to push abrasives to the surface of the workpiece for processing. It is called shot peening, which is what we often call shot peening. Since sand was an abrasive that could be used in the early days of shot peening technology, shot peening was always called sandblasting glass at that time and for a long time afterward.
The phenomenon of sandblasting (shot peening) is common. In nature, sand, gravel, and dust constantly impact mountains and slowly wear them away, but this process is quite slow and not easy for us to notice.
Among various surface pretreatment methods, sandblasting (shot peening) has a more complete effect, stronger adaptability, and a wider range of applications. This is because: it can clean the surface of steel faster and more completely; only sandblasting can be identified with 4 established finishing grades that we can all bear; sandblasting can clean surfaces that are usually difficult to clean, and some special tools can be used to clean the inner and outer surfaces of pipes, and the cost of sandblasting is relatively low.
Sandblasting glass can achieve the required cleanliness and a certain roughness on the surface to be treated, and improve the adhesion of the coating on the basic surface. No matter how good the coating is, it cannot adhere well to the surface of the workpiece that has not been treated for a long time. The purpose of surface pretreatment is to clean the surface and generate the required roughness on the surface to "lock" the coating. After the surface of the workpiece treated with sandblasted glass is coated with a high-performance industrial coating, the coating life can be more than 3.5 times longer than the same quality coating on the surface treated by other methods. Another advantage of sandblasting glass (shot peening finishing) is that the surface roughness can be determined in advance according to requirements and easily achieved during the finishing process.
