Problems solved by technology

However, the mixing ratio of waste cullet is also different. If the mixing amount is too large, the quality of the glass will be reduced, the glass will become brittle, and the mechanical strength will decrease; if the mixing amount is too small, the effect of mixing will not be achieved.

Abstract

The invention discloses a plate glass highly doped with broken glass. The plate glass contains broken glass and auxiliaries in a mass fraction ratio of (70 to 30)-(90 to 10), wherein the auxiliaries include silica sand, fluorite, dolomite, limestone, calcined soda, mirabilite, a crystallization agent and coal powder. By substantially increasing the adding amount of the broken glass, the efficient utilization of waste is realized, and meanwhile, the problem of clarifying of the glass in a secondary re-melting process can be solved. Meanwhile, the invention further discloses a preparation method of the plate glass highly doped with the broken glass. The preparation method comprises the following steps: preprocessing, examination, mixing, smelting, forming and the like. The preparation method is applied to cooperative preparation of the plate glass highly doped with the broken glass, the highest melting temperature of the plate glass is decreased, the service life of a kiln is prolonged, and the melting efficiency is improved.

Description

technical field [0001] The invention belongs to the field of chemical metallurgy, in particular to flat glass highly mixed with cullet and a preparation method thereof. Background technique [0002] With the development of science and technology and the progress of society, a large amount of cullet will be produced in the process of glass production, processing and use, and the waste of glass in society will also produce a large amount of waste cullet. According to the survey, there are hundreds of glass production enterprises in my country, and the damage of daily-use glass alone is about 2 million tons every year, while the recycling rate of cullet in my country is only about 20%. In recent years, with the mature development of glass production process control means and the fierce competition in the glass market. Reducing production costs and improving market competitiveness are issues that every enterprise must face squarely. There are many ways to reduce production cos...
