Embodiment 1

[0033] Take sodium fluoride, potassium fluoride, ammonium sulfate, and potassium sulfate to make A powder in a weight ratio of 8.0:6.0:4.0:1.0, and make B powder with calcium fluoride and barium sulfate in a weight ratio of 5.0:5.0. A powder, B powder and ultrapure water are made into a solution in a weight ratio of 75:10:1000, and the pH is adjusted to 3.0 with sulfuric acid to make a frosting solution. Put the pretreated glass sample into the frosting solution, take it out after frosting for 2.0min under the condition of 25°C magneton rotation speed 120r / min, wash it with pure water and dry it, measure its roughness Ra and gloss Gs, Taking microscope pictures such as figure 1 .

[0034] Pretreatment steps: glass sample—washing with chromic acid lotion—washing with ultrapure water—drying—applying protective film.

[0035] Such as figure 1 , it was found that the surface of the frosted glass sample was not uniform, and the size gap of ultrafine crystal grains was too larg...

Abstract

The invention relates to glass frosting technologies in the field of chemical processing and particularly relates to an ultracrystallite anti-glare frosting solution for colored glass and a frosting method for the colored glass. The method comprises the steps of preparing powder A from sodium fluoride, potassium fluoride, ammonium sulfate and potassium sulfate which are in the weight ratio of (7.0 to 8.2): (3.5 to 4.5): (1.8 to 2.2): (0.8 to 1.3), preparing powder B from calcium fluoride and barium sulfate which are in the weight ratio of (4.7 to 5.2): (5.8 to 6.3), adding the powder A and the powder B into ultrapure water according to the weight ratio of 75.0: 11.0 so as to prepare a solution, adding a dispersant into the solution, adjusting the pH to 3.0 with sulfuric acid so as to prepare the frosting solution, and carrying out frosting on the glass. Frosted inorganic glass has superior anti-glare effect compared with that of the traditional methods, the roughness Ra and glossiness Gs of the frosted inorganic glass are controllable in size, and the product quality is of uniformity and consistency.

Description
