Method for reducing microbubbles of alumina silicate glass

Abstract

The invention relates to a method for reducing microbubbles of a piece of alumina silicate glass. The optimal founding and homogenization effects are realized by special grain size distribution of glass batch, the alumina silicate glass with fewer bubbles and small diameter bubbles is obtained, and the use requirement of the special glass for electronic information display is met. Specifically, the granular size of the glass batch such as feldspar, silica sand, dolomite, limestone, sodium carbonate and mirabilite is controlled to be in a specific range, due to the optimization and matching of larger granular raw materials and smaller granular raw materials, the reaction homogeneity and completeness of the batch are realized, the optimal founding effect is realized, and the excellent alumina silicate glass with fewer bubbles and small diameter bubbles is obtained.

Description

technical field

[0001] The invention relates to a method for preparing aluminosilicate glass, in particular to a method for reducing microbubbles in aluminosilicate glass by controlling the specific particle size gradation mode of batch materials. Background technique

[0002] Bubbles are the most common defects in the glass melting process, which will affect the appearance, transparency, mechanical strength and hardness of glass products. When the glass with a certain amount of microbubbles is used for electronic information display, it will be deadly. Contents of the invention

[0003] The purpose of this invention is to solve the defect of a certain number of microbubbles existing in the existing aluminosilicate glass, and propose a technical solution to achieve better melting and homogenization effects by using a specific particle size gradation of the batch material to obtain bubbles Aluminosilicate glass with small quantity and small cell diameter.
