Sandblasting is another spraying process besides spray coating and painting. This process can be divided into two stages, namely the pre-processing stage and the process stage, which achieve different effects in different ways. The quality and performance of the surface of the workpiece after sandblasting has changed.

Vacuum plating UV primer In the pre-treatment stage of sandblasting, it is necessary to ensure that the surface of the workpiece is treated correspondingly before being sprayed and sprayed to meet the basic requirements of sandblasting. The quality of the treatment before sandblasting affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating.

That is to say, if the pre-treatment of the blasting process is not good, the rust on the surface of the workpiece will continue to spread under the coating, causing the coating to fall off. The carefully cleaned surface and the generally cleaned workpiece are compared by the exposure method, and the service life is also significantly extended.

There are many methods for surface cleaning involved in sandblasting, but it is generally accepted and applied by solvent cleaning, pickling, manual tools or power tools. The surface-cleaned workpiece has a good foundation and is ready for subsequent sandblasting.

The blasting of the workpiece is carried out by using compressed air as a power to form a high-speed jet beam, which sprays the spray material at a high speed to the surface of the workpiece to be processed, so that the appearance of the outer surface of the workpiece changes. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece can be given a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece are improved.
