Lepidolite-containing composite glass flux and preparation method thereof

Abstract

The invention relates to a lepidolite-containing composite glass flux, which is prepared from the following raw materials by weight: 2-2.5 parts of cerium nitrate, an appropriate amount of distilled water, 1-1.5 parts of porous nanometer carbon balls, 6-7 parts of lepidolite, 2-3 parts of sodium bicarbonate, 40-45 parts of bismuth oxide, 4-5 parts of boron oxide, 1.5-2 parts of silica sol, and a proper amount of ammonia water. According to the present invention, with the flux, the matching material melting is easily achieved, the melting temperature can be reduced, and the energy source consumption can be reduced; the lepidolite is added, such that the melting temperature can be reduced, the appearance defect of the prepared glass is less, and the yield is high; and with the process, the nano-scale cerium oxide is wrapped on the particle surface while the porous nanometer carbon balls are added so as to progressively clarify and quickly and completely eliminate the gas seeds.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a composite glass flux containing lepidolite and a preparation method thereof. Background technique [0002] Float glass is a method of flat glass production. In the production of float glass, a very important link is to continuously put the batch materials into the melting furnace through the feeder for melting, and heat them at high temperature to form uniform, pure and transparent glass. And meet the molding requirements, it is a continuous and single liquid phase process of glass, which is one of the main stages in the glass manufacturing process. The melting speed and the rationality of melting have a great impact on the output, quality, qualification rate, production cost and fuel consumption of glass. It has a great influence on the life of the tank and kiln. The glass melting process includes 5 stages, namely the formation of silicate, glass formation, glass clarificat...

AI Technical Summary

Problems solved by technology

When fluorite is used, the glass melting process in the kiln is a high-temperature reaction, and the use of glass liquid containing fluorine will cause serious erosion of the kiln pool wall, reducing the service life of the kiln and the safety of production

Moreover, a large amount of fluoride produced in the production process is discharged into the atmosphere along with the flue gas, resulting in air pollution
