Problems solved by technology

High borosilicate and high aluminosilicate glass have very low coefficient of thermal expansion, high temperature resistance, 200 degree temperature drastic change resistance, acid resistance, alkali resistance and water resistance, and excellent corrosion resistance. These characteristics of high borosilicate and high aluminosilicate glass determine its It is more difficult to process and handle than ordinary sodium silicate glass. Etching with general frosting method will result in poor frosting effect and uneven frosting particles.
There are many methods and techniques for making anti-glare glass in China, but they are mainly aimed at ordinary soda-lime-silicate glass, and there are no patents on the anti-glare effect of superhard glass such as high borosilicate, such as CN201010270000.5 One-step method of manufacturing low-reflection glass. This patent is mainly aimed at ordinary soda-lime-silica glass. Secondly, the anti-glare glass produced by the patented method can only have a small range of technical parameters such as gloss and light transmittance. Internal changes, can not meet the needs of customers, another example is CN200810038886.3 is anti-glare treatment for ordinary soda-lime-silica glass, through its solution ratio frosted high borosilicate glass, the anti-glare effect is not good and the surface frosted particles uneven
