The difference of sand blasting treatment compare with other surface treatment
Sand blasting and anodizing surface treatment is widely used,especially sandblasting oxidation what the effect is very good. It is the use of compressed air as the power to form a high-speed jet beam, spray (copper sand, quartz sand, iron sand, sea sand, emery, etc.) and other high-speed injection to the surface of the workpiece to be treated, so that the appearance of the outer surface of the workpiece changes, due to the mechanical properties of the workpiece surface are improved, thus improving the fatigue of the workpiece, increasing the adhesion between it and the coating, prolonging the durability of the coating film, but also conducive to the peaceful decoration of the paint.
Compare with other pretreatment processes such as pickling and tool cleaning
1) Sand blasting treatment is a more thorough, more general, faster and more efficient cleaning method.
2) Sand blasting treatment can be arbitrarily selected between different roughness, and other processes are not able to achieve this, manual polishing can hit the wool but the speed is too slow action, chemical solvent cleaning clean surface is too smooth is not conducive to coating bonding.
