Problems solved by technology

The strain point of most silicate glasses increases with the increase of the glass former content and the decrease of the modifier content. At the same time, it will bring difficulties to high-temperature melting and clarification, resulting in intensified erosion of refractory materials, increasing energy consumption and production costs.
Such batches are relatively refractory, so it is necessary to increase the melting temperature or take a long time to melt

Abstract

The invention relates to the field of glass manufacturing, and discloses a glass composition, aluminosilicate glass, a preparation method and application thereof. Based on the total weight of the glass composition, the glass composition includes 50-90% by weight of glass powder and 10-50% by weight of cullet. The aluminosilicate glass prepared by the method of the invention has a relatively low melting temperature and good toughness, the product yield rate is high, and the production cost is low, which is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a composition for glass, aluminosilicate glass and a preparation method and application thereof. Background technique [0002] With the development of display technology and the popularity of smart phones and tablet computers, the performance of smart devices such as smart phones and tablet computers allows people to enjoy high-level business and entertainment activities with the convenience of wireless communication. Under such a trend, displays are constantly updated, and people's performance requirements for displays are also constantly improving. At the same time, in order to reduce the burden of using handheld devices, products are becoming lighter and thinner. Under the guidance of this development trend, the display panel is developing towards thinner and ultra-high-definition display, and the panel manufacturing process is developing towards higher processing temperatur...
