Problems solved by technology

Disadvantages are long melting time, complex process, long nucleation and crystallization time, long production cycle, high production cost, because it needs to add 6% to 10% (mass fraction) fluorine as a crystal nucleating agent, which causes its influence on glass ceramics melting. The kiln is highly corrosive, and the calendered glass-ceramic has very high requirements for the refractory materials of the glass-ceramic furnace. The construction cost of the calendered glass-ceramic furnace is 150,000 to 200,000 to 200,000 per square meter higher than that of the sintering method.

Abstract

The invention discloses a microcrystalline glass aggregate raw material, a method and a raw material and method for preparing a low-fluorine high-strength microcrystalline glass plate. The microcrystalline glass aggregate raw material comprises 2-mesh glass ceramic granules, 8-mesh glass ceramic granules, 10-mesh glass ceramic granules and 20-mesh glass ceramic granules. Granules are used as raw materials, nucleation treatment, crystallization treatment and sintering treatment are carried out on the granules, and melting treatment for forming is not needed any more, so that the process of preparing the low-fluorine high-strength microcrystalline glass plate is optimized.

Description

technical field [0001] The invention relates to a raw material and a method, in particular to a raw material and method for glass-ceramic pellets and a raw material and method for preparing low-fluorine and high-strength glass-ceramic plates. Background technique [0002] Glass-ceramics is a mixture of microcrystals and glass made of appropriate glass particles through sintering and crystallization. It is hard, dense and uniform, and has no pollution in the production process. The product itself has no radioactive pollution. A new type of environmentally friendly green material is widely used on interior and exterior walls. Therefore, the raw material and method of glass-ceramic pellets and the raw material and method of preparing low-fluorine and high-strength glass-ceramic plates are important building materials. Among the raw materials and methods of glass-ceramic pellets and the raw materials and methods of preparing low-fluorine and high-strength glass-ceramic plates, t...
