SAND BLASTING PROCESS

Sand blasting process is the use of compressed air as the power to form a high-speed jet beam, spray material and other high-speed jet to the need to deal with the workpiece surface, so that the surface of the workpiece surface changes, due to the impact of abrasive on the workpiece surface and cutting action, so that the workpiece surface to obtain a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface is improved. so as to improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, extend the durability of the coating film, but also conducive to the flow and decoration of the coating.

Characteristics:
(1)the workpiece coating, the workpiece bonding before sandblasting can remove all the dirt on the surface of the workpiece rust, and establish a very important basic pattern on the surface of the workpiece (usually called the wool surface), and can be placed by different particle size abrasive, to achieve different degrees of roughness, greatly improve the workpiece and coating, plating bonding force.Or make the bonding piece bonding more firm, better quality.
(2) Cleaning and polishing of the wool surface of the cast and forged parts and the workpiece after heat treatment sandblasting can clean up all the dirt on the surface of the cast and forged parts and the workpiece after heat treatment (such as oxide skin, oil and other residues), and polish the surface of the workpiece to improve the finish of the workpiece, so that the workpiece can show uniform metal color, make the workpiece appearance more beautiful, to
beautify the role of decoration.
(3) Machining parts burr cleaning and surface beautification sandblasting can clean the tiny burr on the surface of the workpiece, and make the surface of the workpiece more flat, eliminate the harm of the burr, improve the grade of the workpiece.And sandblasting can play a small rounded corner at the junction of the workpiece surface, so that the workpiece appears more beautiful and more precise. (four) Improve the mechanical properties of the parts after sandblasting, mechanical parts can produce uniform fine
concave and convex surface on the surface of the parts (basic schema), so that the lubricating oil can be stored, so as to improve the lubrication conditions, and reduce noise to improve the service life of the machine. (five) the effect of lighting for some special purposes of the workpiece, sandblasting can be free to achieve different reflective or matte.Such as stainless steel workpiece, wooden furniture surface matte, frosted glass surface of the pattern, as well as the surface of the cloth wool processing.
