(1) the workpiece coating and the  workpiece processing before bonding to the surface of the workpiece sandblasting  rust and all dirt removal, and the basic schema is very important in  establishing the workpiece surface (usually called the hair surface), but also  through the exchange of different size abrasive, achieve different degrees of  roughness, greatly improve the adhesion of plating the workpiece material and  paint. Or make the adhesive bonding firmer, better quality.    
(2) casting and forging and heat treatment of hair surface cleaning and  polishing the workpiece can clean up sand casting and forging, heat treatment of  the workpiece surface after all contaminants (such as oxide, oil and other  residues), and will improve the workpiece surface polishing finish, to beautify  the role of workpiece. Sand blasting can make the work piece show uniform and  uniform metal color, so that the appearance of the workpiece is more beautiful,  so as to achieve the function of beautifying and decorating.    
(3 the deburring of the machined parts and the surface of the sand can be used  to clean the surface of the workpiece, so that the surface of the workpiece is  more smooth, the harm of the burr is eliminated, and the grade of the workpiece  is improved. And sandblasting at the surface of the workpiece at the junction of  a small rounded corners, so that the workpiece is more beautiful, more precise.     
(4) improving the mechanical properties of mechanical parts by sandblasting, can  produce fine uniform convex surface on the surface of parts (basic schema),  storing the lubricating oil, so that the lubrication condition is improved, and  reduce the noise and increase the service life of the machine.    
(5) the role of light decoration 1, a variety of workpiece surface polishing, so  that the surface of the workpiece more beautiful. 2, so that the workpiece to  achieve smooth and reflective requirements. For some special purpose parts,  sandblasting can be achieved at any time to reflect different or sub light. Such  as stainless steel and wooden furniture surface actinic, frosted glass surface  pattern, and fabric surface texturing etc..    
(6) eliminate stress and surface strengthening to the surface of the workpiece  through the sand ball, eliminate stress and increase the surface strength of the  workpiece, such as the surface treatment of the workpiece, such as the spring,  the machine tool and the aircraft blade. As a conventional sandblasting abrasive  jet technology through continuous development, improvement and perfection, with  its unique processing mechanism and extensive processing and application in  surface treatment industry to make it more and more popular in nowadays, has  been widely used in machinery manufacturing, instrumentation, medical equipment,  electronic appliances, textile printing and dyeing machinery, machinery,  chemical machinery, food machinery, tools, cutting tools, measuring tools, mold,  glass, ceramics, handicrafts, machinery repair and so on many fields.

1, the work should be done before the personal protection
2, shall not use the work pressure higher than the license
3, the use of abrasive cleaning, to prevent the spray plug
4, after the end of the tank should be unloaded to zero
