Sandblasting is a surface treatment process for workpieces. Compressed air is used as power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, causing the appearance or shape of the workpiece surface to change.
Due to the impact and cutting effect of abrasives on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, which improves the mechanical properties of the surface of the workpiece, thereby improving the fatigue resistance of the workpiece and increasing its and coating The adhesion between them extends the durability of the paint film and is also beneficial to the leveling and decoration of the paint.
