The introduction of sand blasting
The sand blasting is also a surface treatment of steel products, which is a process of cleaning and roughening the surface of the matrix by the impact of high-speed sand flow. It uses compressed air as the power to form a high-speed jet jet to spray the material to the surface of the workpiece to be treated, so that the appearance or shape of the surface of the workpiece surface changes. Due to the impact and cutting effect of abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface can be improved. Therefore, it improves the fatigue resistance of the workpiece, increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the flow and decoration of the coating.
The sand blasting is widely used in the surface treatment of steel products. It is mainly used in the following aspects:
The workpiece processing before plating, adhesive workpiece sandblasting to scale on the surface of the workpiece and all dirt removed, and the surface it is very important to set up the basis of the schema (usually the so-called hair side), but also by changing different particle size of abrasive, such as flying abrasives abrasive to different degree of roughness, greatly improve the workpiece and the adhesion strength of the coating, plating materials.Or make the adhesive bonding more solid, better quality.
Cleaning and polishing of casting parts and workpieces after heat treatment sandblasting can clean all dirt (such as residue such as oxide skin and oil) on the surface of castings and forging parts and workpieces after heat treatment, and polish the surface of workpieces to improve the smoothness of the workpieces, which can make the workpieces show uniform and consistent metallic colors, and make the appearance of workpieces more beautiful and beautiful.
Burr cleaning of machined parts and surface beautification Sandblasting can clean the tiny burrs on the surface of the workpiece, make the surface of the workpiece more even, eliminate the harm of burrs, and improve the grade of the workpiece.And sand blasting can hit a small corner at the junction of the workpiece surface, so that the workpiece appears more beautiful, more precise.
Improve the mechanical properties of the parts, the mechanical parts after sandblasting, can produce uniform fine concave and convex surface on the surface of the parts, 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 machinery.
Finishing action For some special purpose work pieces, sandblasting can achieve different reflective or matte light at will.Such as the grinding of stainless steel workpiece, plastic, polished jade, wooden furniture surface matte, ground glass surface pattern, and cloth surface wool processing.
