Scrub process of emulsion bottle
2022-08-23
Scrub is the process by which,for example,cosmetic lotion bottles become smooth and non-smooth,with light shining on the surface to form a diffuse reflection.In chemical frosts,glass is mechanically or manually ground with emery,silica sand,pomegranate powder,and other abrassers to form a uniform rough surface,or glass and other objects can be treated with hydrofluoric acid solution to form frosted glass. Both matte and sandblast are used to cover the glass surface,allowing light to scatter relatively evenly through the lamp shade.It is difficult for the average user to distinguish between these two technologies.The following describes how each of these technologies is manufactured and how to identify them. 
Sanding is when glass is dipped into a prepared acidic liquid(or coated with an acidic paste),and the surface of the glass is corroded with a strong acid.The ammonia fluoride in the strong acid solution makes the surface of the glass crystal.Therefore,if the sanding process is done well,the surface of the frosted glass is very smooth,and the crystals formed by scattering produce a hazy effect.If Cosmetic Glass Lotion Bottle have a relatively rough surface,this indicates that the acid is eating away at the glass heavily,or that some of them are still crystal-free.The process is characterized by the appearance of shiny crystals on the surface of glass formed under critical conditions.The main reason is that ammonia fluoride has almost run out.In order to achieve this state,many manufacturers have done many attempts and studies,but have not been able to overcome this difficulty.
