Sandblast

sandblast

The process of cleaning and coarsening the surface of the matrix by the impact of high-speed sand flow. The compressed air is used as the power to form a high-speed jet beam to spray the spray material (copper ore, quartz sand, emery, iron sand, Hainan sand) at high speed to the surface of the workpiece that needs to be treated, so that the appearance or shape of the outer surface of the workpiece surface changes, due to the impact of abrasive on the surface of the workpiece and cutting action, so that the surface of the workpiece to obtain a certain degree of cleanliness and different roughness, The mechanical properties of the workpiece surface are improved, so the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating is extended, and the flow and decoration of the coating are also beneficial.
