Sand blasting machine in use, need to understand its process, so as to reduce equipment operation failure, promote the use of equipment efficiency, and for the convenience of more users to understand the use, the next detailed process is introduced to understand.

First, pretreatment.

Sandblasting machine for the workpiece in the spraying, spraying protective layer (paint or other anticorrosive materials), the surface of the workpiece should be seriously treated, known as pretreatment.

The quality of pretreatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating, because the better coating film (layer) is adhered to the surface that is carefully cleaned. If the pretreatment work is not good, the rust will continue to spread under the coating and make the coating flake off. After careful cleaning of the surface and the general simple (manual sandpaper or brush) cleaning of the workpiece, with exposure method for coating comparison, life can be 4-5 times. There are many methods of surface cleaning, but the most commonly accepted method is :A. solvent cleaning B. C. hand tools D. power tools

In these ways, each way has its own scope of application, but in all surface cleaning methods, sandblasting method is more thorough, bottom, more general, more extensive way, the reason is:

A, sandblasting is better than other ways to clean the surface of the workpiece.

B, No other process allows you to choose between four recognized, generally accepted cleanliness levels.

Second, the sand blasting.

Sandblasting machine is using compressed air as power to form high speed injection beam, the spraying material (copper ore, quartz sand, iron sand, sea sand, silicon carbide, etc.), such as high speed jet to need to deal with the surface, the surface appearance change of components, due to the abrasive effect on impact on the surface of the workpiece and cutting, make get some cleanliness and different roughness of workpiece surface, make the surface of the machinery Can be improved, so improve the fatigue of the workpiece, increase the adhesion between it and the coating, prolong the durability of the film, but also conducive to the flow of paint and decoration.
