Pre-spraying treatment-----sand blasting

       A sandblaster is a mechanical device that can use various abrasives (metallic and non-metallic abrasives) to spray onto the surface of a workpiece with the help of compressed air power. The abrasive is sprayed onto the surface of the workpiece for impact grinding to remove impurities, variegated colors and oxide layers on the surface, and at the same time roughen the surface of the medium and increase the surface area, which can improve the adhesion of the coating and enable the coating to produce the strongest Acid and alkali resistance, improve the coating quality, reduce the residual stress on the surface of the substrate and improve the surface hardness of the substrate.



According to the injection principle, the sandblasting machine can be divided into pressure feeding type and suction feeding type. Because the compressed air and abrasive are mixed and sprayed in the same container, the compressed air can be fully utilized, and the air flow and sand flow are easy to adjust, which is suitable for large-area treatment and small-scale treatment. Parts sandblasting treatment, the XPB series and AC series sandblasting machines currently produced by Xinye Company are pressure-feeding sandblasting machines. The control methods are divided into three series: manual control, pneumatic control and electric control. In addition, there are pressure-feeding and suction-feeding box-type sandblasting machines used in light industry, as well as various non-standard automatic sandblasting machines customized according to user requirements.



 



Typical applications: rust removal, scale removal, oil removal, residual stress removal, increase workpiece surface roughness...



Typical application of mold cleaning: high cleaning efficiency, thorough, uniform and fine.



Typical application for post-processing of garments: The impact of sandblasting is used to remove the dyed layer on the surface of the fabric, which is more efficient than any method
