First, what is glass frosting powder?
Glass frosting powder, usually fluoride (such as ammonium fluoride, potassium fluoride, calcium fluoride) as the main component, and then add ammonium sulfate, barium sulfate, potassium sulfate and other additives to prepare frosted powder.
When used, sulfuric acid or hydrochloric acid is added to prepare frosting liquid, glass products are placed in this frosting liquid, and the hydrofluoric acid generated by the reaction of frosting powder and acid erodes glass products to achieve frosting effect.
Second, what is the difference between frosted powder and etching cream?
Glass frosting is a method of treating the glass surface with a solution or other chemical raw materials formulated with glass frosting powder. Frosting is one of the methods of glass deep processing, which can increase the added value of glass and thus increase the value of glass products. At present, many art glasses on the market are processed by glass frosting and then coloring.
Glass etching cream and glass frosting powder are relatively good materials for frosting glass products, but they are suitable for different operation methods. At the same time, their role in the glass industry is complementary and complementary.
Frosting cream is mostly suitable for partial frosting of glass products, which is more convenient to operate; However, frosting paste is not very suitable for large-area glass etching, the main reason is that when it is used for large-area glass etching, it is easy to produce uneven frosting surface and other phenomena. Masking paste is commonly used in screen printing.
Compared with frosting paste, the operation process is slightly more complicated with frosting powder, that is, it is necessary to prepare the frosting powder into a solution. However, frosting powder is suitable for almost all glass products. It can not only frost glass products such as glasses, glass bottles, glass lighting, etc. that can be soaked into the solution; It can also be sanded for glass products such as flat glass and sliding door glass that should not be soaked in frosting liquid, but need frosting. There are two ways to frost glass products with frosting powder: soaking and sanding.
