Sandblasting process is using compressed air as the power, the high-speed beam will be sprayed iron sand, ceramic sand and other abrasive shot to the surface of the workpiece for treatment.

Allow the workpiece surface treatment to change. Such abrasive is used to impact and cut the workpiece, so that the surface of the workpiece to a certain degree of cleanliness and different roughness, so that the mechanical properties of the surface of the workpiece to improve.

The pre-treatment stage of sandblasting process refers to the treatment of the workpiece surface before it is sprayed and coated with protective coating. 

The pretreatment quality of sandblasting technology affects the adhesion, appearance, moisture and corrosion resistance of the coating. 

If the pretreated workpiece is not done well, the corrosion will continue to spread under the coating, making the coating flake off. 

After careful cleaning of the surface and general cleaning of the workpiece, with the sun method for coating comparison, the life difference can be 4-5 times. 

There are many ways to clean surfaces in sandblasting processes, but the most commonly accepted methods are: solvent cleaning, pickling, hand tools, and power tools.
