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.
