Sand Blasting Metal Plate Production Process
- Aug 15, 2018 -

1 Blasting process pretreatment stage: Sand blasting process pretreatment stage refers to the workpiece in the spray, spraying protective layer before the workpiece surface should be processed. The pretreatment quality of the sand blasting process affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. The pretreatment work is not good, rust will continue to spread under the coating, so that coating flakes off. After careful cleaning of the surface and the general simple cleaning of the workpiece, using exposure method for coating comparison, life can be 4-5 times different. Surface cleaning methods are many, but the most commonly accepted methods are: solvent cleaning, pickling, hand tools, power tools.

2 Blasting Technology Stage: sandblasting process is the use of compressed air for the power to form a high-speed injection beam, metal signs will spray and other high-speed injection to deal with the workpiece surface, so that the outside surface of the workpiece changes, due to the impact of abrasive on the workpiece surface and cutting role, so that the workpiece surface to obtain a certain degree of cleanliness and different roughness, The mechanical properties of the workpiece surface are improved.
