Principle of Glass Sand Blasting Process Operation

Sand blasting is a process that takes compressed air as motive to push abrasive grains on workpiece surface finishing. This is what we usually call shot-blasting or shot peening treatment. Because sand was the only material available at the initial stage of shot blasting technology, at that time and even now shot blasting is called sand blasting.

Sanding blasting is a common phenomena. In nature, sand, macadam and dust are impacting the mountains, the gradual abrasion is so slow that human could hardly perceive. Among all kinds of surface sanding blasting processes, sand blasting is most complete in effect, has best adaptability and widest applications. Only sanding blasting can be evaluated by the four acceptable standards.

Sand blasting can be adopted to surfaces that are hard to clean, some special tools can be employed to clean the inner surface of tubes, and sand blasting costs the least. Besides, sandd blasting process can make the surface both clean and maintain certain roughness, namely, to achieve coating's adhesive force on the surface.
