Principle of abrasive blasting

Sandblasting is powered by compressed air, to form the appearance of high-speed jet beam will spray material (copper sand, quartz sand, silicon carbide, iron ore, Hainan sand) high-speed jet to the surface to be processed, so that the outer surface of the workpiece surface or shape changes due to impact and abrasive cutting action on the workpiece steel fiber for concrete steel fiber for concrete  surface, the surface of the workpiece to obtain a different cleanliness and roughness, so that the mechanical properties of the surface is improved, thereby improving the fatigue resistance of the workpiece, increasing the it and the adhesion between the coating to extend the durability of the coating, but also conducive to peace and decorative paint flow
