What's The Sand Blasting

- Jul 13, 2020-

The process of cleaning and roughening the surface of the substrate using the impact of high-speed sand flow. Using compressed air as the power to form a high-speed jet beam to spray the spray material (copper ore sand, quartz sand, emery sand, iron sand, Hainan sand) to the surface of the workpiece to be processed at high speed, so that the appearance or shape of the outer surface of the workpiece surface changes Because of the impact and cutting effect of the abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved, and its coating is increased. The adhesion between the layers extends the durability of the coating film, and is also beneficial for the leveling and decoration of the coating.
