Production process of AG (anti-glare) glass

Abstract

The invention provides a production process of AG (anti-glare) glass. The process comprises the following steps of smelting glass raw materials by utilizing a smelting furnace so as to form glass fluid; then enabling glass to be molded through a fusion tin chamber by using a float glass process to form an earlier-stage glass pane; then annealing the earlier-stage glass pane by utilizing an annealing chamber to form a finished glass pane; then cutting and edging the finished glass pane to make a glass template; then polishing the glass template; then washing the glass template; then making hardmasking film; then making an ultraviolet curing polymer layer; then making a model; then making a curing layer with the model; then demolding; then etching the glass template by using one of reactiveion etching or inductive coupling plasma etching or using both, wherein the etching speed of the hard masking film is lower than the etching speed of the glass template. Compared with the prior art,the production process of the AG glass can be used for high-efficiency and high-quality production of the AG glass, and the AG glass has excellent performance.

Description

technical field [0001] The invention relates to the field of glass processing technology, in particular to a production technology of AG glass. Background technique [0002] AG glass, also known as anti-reflection glass and anti-glare glass, is called Anti-glareglass in English, which is a kind of glass that is specially processed on the glass surface. Its characteristic is to change the reflective surface of the original glass into a matte non-reflective surface (uneven surface). The principle is to process the double or single side of the high-quality glass formwork through special processing. Compared with ordinary glass, it has a lower reflectance, and the reflectance of light is reduced from 8% to less than 1%. Using technology to create a clear and transparent visual effect, so that viewers can experience better sensory vision. [0003] AG glass can also be produced by the float method, and the forming process of the float glass production is completed in a tin bath ...

AI Technical Summary

Problems solved by technology

However, photovoltaic glass has higher requirements on glass surface quality, while molten tin must be used in the production of float glass, and in order to improve the fluidity of the glass fluid, which is more conducive to the flattening of the glass fluid and improve efficiency, the temperature of the molten tin must be at a certain level. The higher the range is required, the better, so there is a contradiction. The higher the temperature of the molten tin liquid, the more tin vapor will appear. When the tin vapor reaches a certain concentration, it will gather into tin liquid droplets and fall on the glass ribbon. Adhesion in the form of oxides will cause damage to the glass and seriously affect the quality of the glass

Moreover, the performance of AG glass needs to be improved.
