Sand blasting is a process of workpiece surface treatment, that adopts compressed air as the power to form a high-speed jet beam to spray the sprayed material to the workpiece surface to be treated at high speed, so as to change the appearance or shape of the workpiece surface. The compressed air is used as the power to form a high-speed jet beam to spray the sprayed material to the workpiece surface to be treated at high speed, so as to change the appearance or shape of the outer surface of the workpiece surface, Due to the impact and cutting effect of abrasive on the workpiece surface, the workpiece surface can obtain certain cleanliness and different roughness, and the mechanical properties of the workpiece surface can be improved.

Advantages of silicon carbide sand blasting abrasive:

1. The fastest and most thorough cleaning of steel surface; Only sand blasting can be evaluated with 4 cleaning grades that are acceptable to everyone;
2. Sand blasting can clean the surface that is usually difficult to clean. Some special tools can be used to clean the inner surface of the pipeline, and the cost of sand blasting is the lowest.
3. Silicon carbide sand blasting can make the cleaned surface obtain the required cleanliness and roughness at the same time, and improve the adhesion of the coating on the basic surface.
No matter how good the coating is, it can not be well attached to the workpiece surface without surface treatment for a long time. The function of surface pretreatment is to clean the surface and generate the roughness required to "lock" the coating on the surface.
4. After silicon carbide sandblasting, the surface of the workpiece is coated with industrial coating with good performance, and the service life of the coating can be more than 3.5 times higher than that of the same quality coating on the surface treated by other methods. Another advantage of sand blasting is that the surface roughness can be determined in advance according to the requirements and can be easily achieved in the cleaning process.

Sand blasting Types with different particle sizes shall be selected according to the hardness and planeness. Types of silicon carbide for sandblasting abrasive commonly used by customers: 24 # / 30 # / 36 # / 40 # / 46 # / 54 # / 60#.
