Sandblasting

       Sandblasting, also known as shot peening, is a common surface treatment process for the workpiece, which uses compressed air as a driving force, which is sprayed through high-speed jet (common such as copper ore, quartz sand, Iron sand, sea sand, etc.) high-speed jet to handle the workpiece surface. During this period, the abrasive impact on the surface of the workpiece and the cutting effect, making the workpiece outside the surface or shape changes, to obtain a certain degree of roughness and cleanliness. In addition, the sandblasting treatment also improves the fatigue resistance and mechanical properties of the workpiece, to a certain extent, also increased its adhesion with the coating, effectively improving the durability of the coating, conducive to the leveling and decoration of paint The At present, sandblasting is mainly used for mechanical rust and polishing.
