What are the applications of the sandblasting process?
The blasting process is a surface treatment process that allows other coatings to be better absorbed on the surface of the material,and also produces a special metallic flash effect on the surface of the workpiece.Many people understand the blasting process as well.The application of sandblasting technology is far more than two points.What are the specific applications of sandblasting technology?
(1)Workpiece coating,pre-bonding treatment
Sand blasting can remove all dirt such as scale on the surface of the workpiece,and establish a very important basic pattern on the surface of the workpiece(the so-called rough surface),and can achieve different degrees of roughness by changing abrasives of different sizes.Degree,greatly improve the bonding force of the workpiece with paint and plating.Or make the bonding part stronger and better quality.
(2)Cleaning and polishing of the surface of the casting and forging,and the workpiece after heat treatment
Sand blasting can clean all the dirt on the surface of the workpiece after casting and forging,heat treatment(such as oxide scale,oil stains,etc.),and polish the surface of the workpiece to improve the smoothness of the workpiece,and to beautify the workpiece.Sandblasting can expose the workpiece to a uniform and uniform metallic color,which makes the appearance of the workpiece more beautiful and achieves the effect of beautifying the decoration.
(3)Machining parts burr cleaning and surface beautification
Sand blasting can clean the surface of the workpiece and make the surface of the workpiece smoother,eliminating the damage of the burr and improving the grade of the workpiece.And sand blasting can make small rounded corners at the intersection of the workpiece surface,making the workpiece look more beautiful and more precise.
(4)Improve the mechanical properties of the parts
After the sandblasting of mechanical parts,it can produce uniform and fine concave and convex surface(base pattern)on the surface of the part,so that the lubricating oil can be stored,so that the lubrication condition can be improved,and the noise can be reduced to improve the service life of the machine.
(5)Light decoration
1.Polish the surface of various workpieces to make the surface of the workpiece more beautiful.
2.Make the workpiece smooth and non-reflective.
For certain special-purpose workpieces,sandblasting can be used to achieve different reflections or matt.Such as stainless steel workpieces,matt surface of wooden furniture,patterns on frosted glass surfaces,and texturing on the surface of fabrics.
(6)Stress relief and surface strengthening
The surface of the workpiece is struck by sand pills to eliminate stress and increase the surface strength of the workpiece,such as the surface treatment of workpieces such as springs,machined tools and aircraft blades.
