What is sandblasting

【China Aluminum Network】 Blasting is the use of compressed air as the power to form a high-speed jet beam, the abrasive (steel sand, corundum, glass beads, corundum, etc.) high-speed jet to the surface of the workpiece to be processed, so that the outer surface of the workpiece Changes occur due to the impact of sand on the surface of the workpiece and the cutting action, so that the surface of the workpiece has a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface is improved, thus improving the fatigue resistance of the workpiece, increasing it The adhesion between the coating and the coating prolongs the durability of the coating and also facilitates the leveling and decoration of the coating.

Sand blasting is the use of compressed air as the motive force to form a high-speed jet beam, and the abrasive is jetted to the surface of the workpiece to be processed at a high speed, so that the appearance of the external surface of the workpiece physically changes to meet the quality requirements.

Sandblasting machine application scope:

1. Clean the surface of metal workpieces and non-metal workpieces to remove oxide scales, residual salts and residual oils after heat treatment;

2. Clean oxide scale, sand, etc. of black (or any) colored castings;

3. Clean oxided sand, molding sand, etc. of non-refined precision castings;

4. Clean up residues, micro-burrs, etc. of the machined parts;

5. Clean oxide scale and welding slag of welding parts;

6. Clean the scale and rust layer of cold and hot-rolled steel (steel);

7. Clean mold release agents, deposits, etc. of various mold cavities;

8. Clean the sintered residue on the surface of the ceramic component;

9. Clean the flash of plastic molded parts;

10. Clean up the radioactive elements on the surface of the object;

11. Clear the surface residues on bridges, hydropower stations, ships, and buildings;

12. Clean the rubber adhesion layer of the airport runway;

13. Clean the rust skin and old paint skin on the cars and trains;

14, clear all kinds of pipes and containers;

15. Clean up the old parts of the oil, attachments, etc.;

16, clear the container's residual paint, rust layer and attachments, etc.;

17. Clean the wrong sinter layer on the porcelain;

18, cleaning the surface of the decorative surface scratches and other pre-treatment;

19. Clean the surface of all kinds of workpieces, produce proper roughness and rough surface painting, paint before; before spray; before metal spraying; before galvanizing, chromium, nickel; sandblasting before oxidation treatment;

20. Change the physical and mechanical properties of the workpiece before flaw detection to increase or decrease the surface roughness;

21, change the surface tensile stress to compressive stress;

22, improve the surface lubrication;

23. Reduce the motion noise of the coupling parts;

24, to improve the surface friction coefficient of the workpiece surface finishing metal surface polishing;

25. Obtain a matt or diffuse reflective surface;

26. Cleaning and preservation of polished parchment and other artwork on the surface of wood products Cleaning the surface of brushes, contactors and wiring;

27. Improve conductivity comparison with other pre-treatment processes (pickling, tool cleaning).

Sandblasting features:

1) Sandblasting is a more thorough, more versatile, faster, and more efficient cleaning method.

2) Sandblasting can choose between different roughnesses, but other processes can not achieve this, manual grinding can make rough surface but the speed is too slow, chemical solvent cleaning is too smooth surface cleaning is not conducive to coating Bonding.

The role of sandblasting:

Surface cleaning, surface hardening, and surface beautification of metal workpieces and non-metal workpieces;

1. Surface pre-treatment processing: plating, painting, Teflon, PU, ​​rubber and plastic coating, metal spray welding, titanium plating and other prior treatment and increase the surface adhesion;

2. Surface beautification processing: various metal products of decorative processing and electroplating products extinction and soft matte surface treatment and non-metallic products such as: acrylic, Boli, crystal glass and other surface atomization;

3. Surface cleaning process: removal of metal oxidized or heat-treated black skin, surface pores, surface rust of metals or non-metals, removal of black and pigmented spots on ceramic surfaces or painting regeneration, oxides, residues of rubber molds and gravity die castings Removal of the agent;

4. Surface head removal processing: removal of the heads of plastics, bakelite products, zinc-aluminum die-cast products, etc., and surface trimming of electronic or other parts;

5. Electronic parts processing: surface impurity removal after diffusion of germanium chips, sandblast cutting into small round grains, etching of electronic parts packaging industry, removal of oversized flashes of electronic parts packaging, removal of printed surface of finished electronic parts, and cleaning of ceramic heating materials ;

6. Surface etching: precious metal jewelry, precious stones, glass, stone, stone seals, ceramics, wood and other surface modification etching;

7. Workpiece stress relief processing: parts of the aerospace industry are cleaned and stress relieved, or the refurbishment of defense weapons and extinction rust removal paint;

8. Mold processing: mold surface pears processing (blasting) mold bite flowers and matte surface treatment, increase the adhesion of the mold coating PU, shoe mold, conductive rubber mold, tire mold and electronic product mold cleaning and matte surface treatment.
