Description

technical field [0001] The invention relates to the technical field of glass, in particular to a high strain point aluminosilicate glass with high resistance characteristics. Background technique [0002] With the continuous development of technology in industries such as thin-film solar cells, electronic displays and high-rise buildings, higher and higher requirements are placed on the mechanical and thermodynamic properties of glass original sheets used in these fields. Aluminosilicate glass is used in these fields The best choice for applications. However, the viscosity of aluminosilicate glass is high, and the molding material needs to be stably prepared at a relatively high temperature. At present, the gas combustion method is mostly used in the industrial field, and the batch material is heated and melted through indirect modes such as radiation heat exchange, and its thermal efficiency is low. As a result, a large number of production lines have begun to melt high-vi...
