Sandblasting process of cosmetic glass bottles
2022-09-05
Sandblasting is a kind of work that uses compressed air as the power to push abrasive to the surface of the workpiece for treatment.This is known as sandblasting,also known as shot blasting cleaning.Because sand was the abrasive that could be used in the early days of shot peening,shot peening was known as sandblasting at the time and for a long time thereafter. Sandblasting can give the surface to be cleaned the desired cleanliness and a certain roughness,and improve the adhesion of the coating on the base surface.No matter how good the coating is,it will not adhere to the workpiece surface without a long time of surface treatment.The purpose of surface pretreatment is to clean the surface and produce the roughness required to"lock"the coating to the surface.When the surface of the sandblasted workpiece is coated with a good industrial coating,the service life of the coating is 3.5 times longer than that of the same quality coating on the surface treated by other methods.Another advantage of sandblasting(shot peening)is that the surface roughness can be predetermined on request and can be achieved during the cleaning process. It uses the sand particles ejected from the spray gun at high speed to hit the glass surface,forming fine concave and convex surface,so as to achieve the effect of scattering light,light through the formation of hazy feeling.The surface feel of Cosmetic Glass Bottle Set produced by sandblasting process is rough.Because the glass surface is damaged,it looks like white glass on the light sensitivity of the original transparent glass.
