Sand blasting treatment is the use of compressed air as the power to form a high-speed injection beam, abrasives (steel sand, brown jade, glass beads, gold sand, etc.) and other high-speed injection to the surface of the work piece to be treated, usually, use sandblasting hose, so that the appearance of the outer surface of the work piece changes, due to the sand on the work surface of the work piece The impact and cutting effect, so that the surface of the work piece to obtain a certain degree of cleanliness and different roughness, so that the mechanical performance of the surface of the work piece is improved, thus improving the fatigue resistance of the work piece, increase the adhesion between it and the coating, extend the durability of the coating film, It is also conducive to the leveling and decoration of coatings.
Scope of application of blasters:
1, metal work parts, non-metallic work parts surface cleaning after heat treatment of oxidizing skin, residual salt, residual oil, etc.
2, clean the black (have) color casting parts of oxidizing skin, sand, etc.
3, clean up the residual processing precision castings of oxidizing skin, sand, etc.
4, clean up the residue of mechanical processing parts, micro burrs, etc. ;
6, clean cold, hot-rolled steel plate (type steel) oxidation skin, rust layer, etc.
7, clean up a variety of mold cavity release agent, sediment, etc.
8, clean up the surface of ceramic components sintering residues;
9, clean the flying edge of plastic molding parts;
10, cleaning the surface of the object radioactive elements;
- Clean up the surface residue on bridges, hydroelectric gates, ships and buildings;
12, clean up the rubber attachment layer of the airport runway;
13, clean up the car, train car on the rust cortical layer, old lacquer leather layer;
14, cleaning all kinds of pipes and containers;
15, clean up the oil of old parts, attachments, etc.
16, cleaning the container’s residual paint, rust layer and attachment, etc.
17, clean the porcelain on the wrong sintering layer;
18, clean the decorative surface scratches and other work parts surface pre-treatment;
19, clean the surface of various types of work, produce appropriate roughness and wool paint, paint before, before spraying, before metal spraying, galvanizing, chromium, nickel before, oxidation treatment before sand blasting treatment;
20, before the exploration to change the physical mechanical performance of the work piece to improve or reduce surface roughness;
21, change surface pull stress for pressure stress;
22, improve the lubrication state of the surface;
23, reduce the motion noise of the even parts;
24, improve the friction coefficient of the surface of the workpiece surface of the finish processing metal exterior decorative surface polishing;
25, obtain a bright or diffuse surface; - Cleaning and preserving the surfaces of cleaning brushes, contactors and wiring, etc. of polished parchment and other works of art on the surface of woodwork;
27, improve conductive performance compared with other pre-treatment processes (acid washing, tool cleaning).
