Surface treatment is a surface protection technology that improves the corrosion and wear resistance of products by changing the mechanical, physical and chemical properties of the surface layer of the substrate. The following is an explanation of sandblasting and powder coating in surface treatment

Sand Blast
Main application areas

1. workpiece coating, workpiece bonding pretreatment sandblasting can remove all the dirt from the surface of the workpiece, such as rust, and establish a basic pattern on the surface of the workpiece, and can achieve different degrees of roughness through the exchange of abrasives of different grain sizes to improve the bonding force between the workpiece and the coating, plating materials.

2.casting parts burr surface, heat treatment after the workpiece cleaning and polishing sandblasting can clean the casting and forging parts, heat treatment after the workpiece surface of all the dirt (such as oxidation, oil and other residues), and the workpiece surface polishing to improve the workpiece finish, so that the workpiece appearance more beautiful.

3. machined parts burr cleaning and surface sandblasting can clean the workpiece surface of the tiny burr, and make the workpiece surface more flat.

4.the role of finishing for some special purpose workpiece, sandblasting can achieve different reflective or matte at will.

Powder Coating

Powder coating is used in powder coating, the process used is electrostatic spraying, the use of abrasive spray gun, under the influence of accelerating wind, so that the powder particles sprayed out of the gun body when carrying a positive charge, and negatively charged profiles in contact with the electrostatic adsorption, and then after high temperature curing. It also enhances the adsorption strength of the paint and prevents the paint film from falling off.

From the viewpoint of the process itself, it has quite a high technological component, and the deployment of different colors of paint produces decorative effects of different colors, making it more fashionable and trendy, which makes the powder spraying profiles have a greater space for development and is irreplaceable by the profiles produced by other treatment methods.
