The pretreatment stage refers to the surface treatment of the workpiece before it is sprayed and coated.
The quality of sandblasting pretreatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. If the pretreatment is not done well, the corrosion will continue to spread under the coating, so that the coating will fall off. Comparing the coating life of the surface cleaned carefully with that of the workpiece cleaned simply, the coating life can be 4-5 times longer than that of the workpiece cleaned simply. There are many methods of surface cleaning, but the most commonly accepted ones are solvent cleaning, pickling, manual tools, power tools.
Sand blasting machine stage
Sandblasting machine adopts compressed air as power to form a high-speed spray beam, and sprays the spraying material and other high-speed spraying to the surface of the workpiece to be treated, so that the surface of the workpiece changes. Because of the impact of abrasive on the surface of the workpiece and the cutting effect, the workpiece surface gets a certain degree of cleanliness and different roughness, so that the surface of the workpiece. Mechanical properties have been improved.
