Why Should LiBr Absorption Unit be Shot Blasting?
The principle of shot blasting is to use an electric motor to drive the impeller body to rotate, relying on the role of centrifugal force, the diameter of about 0.2 ~ 3.0 of the projectile (cast steel shot, steel wire cut shot, stainless steel shot and other different types) thrown to the surface of the workpiece, so that the surface of the workpiece to achieve a certain degree of roughness.
The role of shot blasting:
1. Initial cleaning of the LiBr absorption unit surface
All LiBr absorption units are subject to shot blasting. This is not only to remove the unit surface oxidized skin and sticky sand, but also to find the unit surface defects. And shot blasting can also improve the surface finish of the unit which also improve the adhesion of the paint film of the subsequent painting of the unit.
2. Reinforcement of the LiBr absorption unit as a whole
Shot blasting can improve the service life of the unit by changing the welding tensile stress to compressive stress.
