we often say that the shot blasting, shot peening.

Analysis sandblasting process has the advantage
Sandblasting is an abrasive with compressed air as the driving force to promote the work surface for processing, that is, we often say that the shot blasting, shot peening.
Sandblasting is an abrasive with compressed air as the driving force to promote the work surface for processing, that is, we often say that the shot blasting, shot peening. Because there early blasting technology, the sand is the only abrasive used, therefore, for a long time and later period of time, sand blasting has been known.
In fact blasting (shot peening) is widespread, in nature, sand, gravel and dirt in incessantly hitting the mountains, its abrasive slowly away, but this process was very slow and not easy to be aware of our Bale.
In a variety of surface preparation methods, blasting (shot blasting) the effect of the most thorough, most adaptable, widest range of applications, this is because: cleaned steel surfaces fastest and most tungsten carbide inserts; blasting can only have develop acceptable to all four kinds of cleaning performance levels; blast cleaned often difficult to clean the surface, use some special tools to clean the inner surface of the pipe, blasting the lowest cost.
Sandblasting the surface can be cleaned at the same time to obtain the desired cleanliness and the surface roughness of a certain, improve the coating adhesion on the surface of the base two effects. Even the paint is not a good time for the surface treatment is not attached to the surface of the workpiece. The role of surface preparation is to clean the surface and on the surface generation used to "lock" the required coating roughness. After blasting of the surface coating with good performance industrial coatings, the coating life can be compared to other treatment of the same quality on the rear surface of the coating was 3.5 times higher. Blasting (shot blasting) Another advantage is that the surface roughness can be determined in advance upon request, and in the clean-up process is easy to reach.
