Abstract

The invention relates to a high-alumina glass frosting powder and a use method thereof. The high-aluminum glass frosting powder is prepared from the following components in percentage by mass: 30 to 35 percent of ammonium fluoride, 15 to 20 percent of potassium bifluoride, 15 to 25 percent of sulfamic acid, 8 to 10 percent of precipitated barium sulfate, 5 to 8 percent of magnesium fluoride, 5 to8 percent of sodium fluosilicate, 8 to 10 percent of potassium fluoroaluminate, 2 to 3 percent of starch and 0.1 to 0.5 percent of carboxymethyl cellulose. Sulfamic acid is used as an acidity regulator; the formula is further optimized and limited; the problems of corrosivity, safety, environmental friendliness and the like caused by traditional inorganic strong acid curing are avoided; in addition, the frosting liquid cured by adding water has the advantages of proper acidity and uniform and stable system, the surface roughness Ra of the high-aluminum glass is controlled between 0.1 [mu]m and2.0 [mu]m, the effective frosting and control effects of the high-aluminum glass are realized, and the high-alumina glass frosting powder has wide applicability.

Description

technical field [0001] The invention relates to the technical field of glass surface treatment, in particular to a high-alumina glass frosting powder and a use method thereof. Background technique [0002] Glass has unique advantages such as good transparency, high mechanical strength, uniform texture and smooth surface, and is widely used in construction, decoration, instruments, daily necessities, electronics and other industries. Among them, glass has achieved ultra-large-scale applications in electronic industries such as televisions, computers, and mobile phones, forming an industrialized production system for related industries. However, due to the imperfection of glass products, high-intensity light pollution is caused, which makes electronic products a threat to people's vision health. Therefore, how to eliminate the light pollution of glass products has become a research hotspot in the international scientific community. At present, glass frosting is generally use...
