Glass etching method

Abstract

According to the glass etching method provided by the invention, the solution of the alkali and the alcohol organic matter with the carbon atom number of less than or equal to 10 is adopted as the etching solution, and ultrasonic waves are adopted in an assisted manner, so that the roughness of the inner wall of the etched glass is greatly reduced and can reach less than or equal to 6nm, and the glass etching method can be widely applied to etching of various kinds of glass and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of etching, in particular to a glass etching method. Background technique [0002] Glass is a transparent solid at room temperature. It forms a continuous network structure when it melts. It is a silicate non-metallic material that gradually increases in viscosity and hardens during cooling. The main component of ordinary glass is silicon dioxide. Etching of glass can make ordinary glass appear in front of the public in a graceful shape and texture of ice sculpture and jade carving, and it can also provide conditions for new uses of glass. Traditional glass etching uses fluorine-containing etchant. [0003] CN104341111A provides a glass etching solution regeneration method and a glass etching method, using a potassium ion compound to react with aged glass etching solution by stirring, and removing soluble glass slag in the aged solution by filtering. Perform ion exchange treatment on the aging solution, m...

Problems solved by technology

[0004] CN104926145A discloses a glass etching process, wherein the etching solution used includes water, hydrofluoric acid, sulfuric acid, nitric acid, sodium nitrite and acetic acid, but does not involve the problem of surface finish after etching, and uses hydrogen Hydrofluoric acid, more serious toxicity and environmental pollution

CN111116047A discloses a method for manufacturing frosted glass, which uses a fluorine-free alkaline etching solution with a catalyst to etch the atomized layer; strengthens the etched glass substrate, but the obtained It is atomized glass, which cannot guarantee the surface finish after etching

[0007] Therefore, there is an urgent need to develop a glass etching method to solve the problem of the surface finish of the existing glass etching
