Our company is engaged in sand-blasting, the company has united construction team, exploration and research of high-tech, the introduction of high-tech production equipment and a new management model, develop scientific research, production, sales and construction of a large number of persons are welcome We came to visit the negotiations. What is the use of a blast of compressed air as a driving force, to form a high-speed jet beam the spray material (copper sand, quartz sand, silicon carbide, iron ore, Hainan sand) high-speed jet to the surface to be treated, so that appearance or shape of the outer surface of the workpiece surface changes, due to impact and cutting action of the abrasive on the surface, the surface of the workpiece to obtain a certain cleanliness and different roughness, the mechanical properties of the workpiece surface is improved, thereby increasing fatigue resistance, increases the adhesion between it and the coating, extending the coating durability, but also conducive to the paint flow and decorative artifacts.
