Sandblasting is one of the surface treatment of aluminum profile
Sandblasting is to use compressed air as the power to form a high-speed jet beam, spraying the abrasive (steel sand, brown corundum, glass beads, emery, etc.) to the surface of the workpiece to be processed at high speed.
Due to the impact and cutting action of sand, the workpiece surface has a certain degree of cleanliness and different roughness.
Benefits of sandblasting aluminum
The mechanical properties of the aluminum profile surface were improved after sandblasting. It improves the fatigue resistance of aluminum profile, increases the adhesion between it and the coating, prolongs the durability of the coating, and also beneficial to the flow of paint and decoration.
