Abstract

The invention relates to a high-alumina glass frosting powder, a frosting method for high-alumina glass, and a frosted glass and application. In parts by mass, the above-mentioned high alumina glass frosting powder includes the following components: 40-50 parts of ammonium fluoride, 40-50 parts of glucose, 1-5 parts of zinc chloride, and 5-10 parts of solid dispersed particles parts, 1 to 5 parts of alkali metal fluoride salts, 1 part of alkali metal chloride salts, and 60 to 70 parts of citric acid. The components in the above-mentioned frosting powder are coordinated so that the frosting powder can be used for high-alumina glass frosting with good frosting effect and high yield.

Description

technical field [0001] The invention relates to the field of glass surface processing, in particular to a high-alumina glass frosting powder, a frosting method for high-alumina glass, and a frosted glass and application. Background technique [0002] Frosting refers to a method of treating the glass surface with a solution made of frosting powder. Through the frosting treatment, the glass surface has certain effects such as surface roughness and gloss. However, the current frosting process is mostly used for soda lime glass, not suitable for high alumina glass. High alumina glass refers to glass with alumina content greater than 12%. It has the advantages of high hardness, good chemical stability and high mechanical strength, and is widely used. The alumina content of high-alumina glass is much higher than that of soda-lime glass, almost no calcium element, and very low sodium content. Due to the large difference in glass composition, the frosting powder that can be used fo...
