Description

technical field [0001] The invention belongs to the technical field of performance design of high aluminosilicate glass, and in particular relates to a method for determining an ideal chemical strengthening process of high aluminosilicate glass and its application. Background technique [0002] In order to improve the mechanical strength of glass, especially the microhardness, two methods of physical strengthening and chemical strengthening are usually used. Physically strengthened glass is mainly used for window glass of vehicles and ships, and exterior glass of buildings. Physically strengthened glass has low cost, large output, high mechanical strength, good thermal shock resistance, and the highest safe working temperature can reach 287.78°C. However, the deformation problem inherent in the strengthening process of physically strengthened glass limits its application in fields that require high optical quality. The application of chemically strengthened glass is more ex...
