Sandblasting, a process of surface treatment of workpieces.
The compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore sand, quartz sand, diamond sand, iron sand, sea sand) at high speed to the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface is improved, thus improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating film, but also conducive to the smoothness and decoration of the coating.
