The frosting of the glass bottle of cosmetic packaging material knowledge
The frosting treatment in chemistry is to mechanically grind or manually grind the glass with abrasives such as emery, silica sand, pomegranate powder, etc., to make a uniform and rough surface, or use hydrofluoric acid solution to process the surface of glass and other objects. Products become frosted glass and other products. The airtight performance is better after frosting.
It refers to the process of processing the original smooth surface of ordinary glass to change its surface texture from smooth to rough (transparent to opaque). One or both sides of the plate glass are mechanically or manually ground with abrasives such as emery, silica sand, pomegranate powder, etc., to make a uniform and rough surface. The surface of the glass can also be processed with hydrofluoric acid solution, and the resulting product becomes frosted grass. The surface of the frosted glass is processed into a rough surface, which diffuses the penetrating light, and has the advantage of light transmission and opacity.
