Problems solved by technology

However, this kind of tempered glass also has its own inherent shortcomings. Compared with ordinary glass, the concept of self-explosion of tempered glass has greatly increased; this is reflected in the fact that tempered glass will spontaneously appear cracks or bursts under the condition of no load and no external impact. Case
This not only affects the performance of tempered glass, but may also cause harm to human body or building safety

Abstract

The invention relates to the technical field of glass processing, in particular to a self-bursting resistant microcrystalline glass. The modified microcrystalline glass comprises the following raw materials: 15-20 parts of fluorite, 10-15 parts of dolomite, 10-13 parts of calcite, 30-35 parts of vanadium-titanium-iron ore, 5-8 parts of soda ash, 4-6 parts of silicon phosphate, 0.17-0.24 part of boron oxide, 0.05-0.12 part of tin oxide, 01-0.03 part of a lanthanide series trace additive. Specifically, the lanthanide series trace additive contains lanthanum, praseodymium and neodymium three elements. The preparation process of the glass includes compounding, melting, clarifying, forming, toughening treatment, homogenizing treatment and other steps. The glass treated by the process has very stable internal and external stress distribution, can maintain good strength, hardness and impact resistance, and also can reduce the self-bursting rate of glass.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a self-explosion-proof glass-ceramic. Background technique [0002] Glass is a non-metallic solid material prepared from inorganic mineral raw materials such as quartz sand, barite, barium carbonate, limestone, feldspar, soda ash; this material has good insulation and light transmission, high strength and high hardness , excellent processing characteristics, is a very good building material. [0003] In order to further improve the strength, toughness and impact strength of glass, people use physical or chemical methods to form compressive stress on the glass surface and tensile stress inside the glass. This strengthened glass is called tempered glass. However, this kind of tempered glass also has its own inherent shortcomings. Compared with ordinary glass, the concept of self-explosion of tempered glass has greatly increased; this is reflected in the fact that tempered...
