Problems solved by technology
[0003] At present, most of the second-strong OGS factories in the same industry use ordinary single hydrofluoric acid to dilute it as a chemical strengthening solution. Fluorosilicic acid is easily produced in the chemical reaction, which affects the strength of the OGS glass after secondary strengthening, and chemical etching " In the process of "aluminosilicate glass material", glass powder will adhere to the edge of the glass, which will block the etching glass and easily cause bumps

The invention provides OGS (One Glass Solution) glass secondary intensifying liquid. The OGS glass secondary intensifying liquid comprises 2.5%-3.5% of hydrofluoric acid, 4.5%-8% of hydrochloric acid, 3.5%-5% of nitric acid and the balance of water and is prepared by mixing the components. The OGS glass secondary intensifying liquid provided by the invention is capable of stabilizing etching rate, softening glass powder, inhibiting generation of fluosilicic acid, greatly increasing the strength of OGS glass and timely removing glass powder adhered to the edges of the glass in a process of etching the aluminum-etching glass so as to reduce the blockage of the glass powder to the etching glass, so that convex points do not occur on the glass, the yield of the OGS glass is increased, the quality requirements on the secondary intensifying of the OGS glass are met, and the demands of customers are satisfied.
Description
technical field [0001] The invention relates to the technical field of chemical etching, in particular to a secondary strengthening liquid for OGS glass and a preparation method thereof, and also relates to a secondary strengthening process for OGS glass. Background technique [0002] The secondary strengthening process of OGS glass is a necessary process in the production of touch screens of mobile phones or tablet computers, and chemical etching is an important process in the secondary strengthening of OGS glass. Make the micro-cracks on the edge of OGS glass products disappear, so as to achieve the purpose of improving glass strength. [0003] At present, most of the OGS second-strength factories in the same industry use ordinary single hydrofluoric acid as a chemical strengthening solution. It is easy to generate fluorosilicic acid in the chemical reaction, which affects the strength of the OGS glass after secondary strengthening, and chemical etching " In the process o...
