Sandblasting room is widely used in ship industrial, military and construction machinery , petrochemical machinery, hydraulic machinery and bridge components , machinery and other locomotives of large metal structures, suitable for sand-blasting and shot peening front surface coating strengthening treatment .� After sandblasting able to completely remove the workpiece surface welding slag , rust , oxide skin , oil, etc. , to improve the surface adhesion of the coating to achieve long-term preservation purposes. Furthermore, for shot peening treatment, the surface stress of the workpiece can be eliminated to improve the strength of the workpiece . Sand blasting booths is a closed space, includes blasting system, abrasive circulatory system and rust removal system, etc. Sand blasting booths is mainly used for surface cleaning and strengthening of steel, castings, aluminum alloy parts and other parts. Through the shot blasting can remove the complex work piece surface contamination, the oxide skin, welding slag, the waste paint and so on, causes the work piece surface to be bright and clean, simultaneously reduce the work piece internal stress, enables the work piece surface to obtain the strengthening, thus achieves enhances the work piece surface and the intrinsic quality goal.
