Chrysotile tailing microcrystal glass and preparation method thereof

Abstract

The invention discloses chrysotile tailing microcrystal glass and a preparation method thereof and belongs to the technical field of chrysotile tailing control and comprehensive utilization. The chrysotile tailing microcrystal glass comprises the following raw materials in percentage by weight: 30 to 50 percent of chrysotile tailing, 27 to 50 percent of fly ash, 9 to 10 percent of limestone, 0 to 4 percent of industrial barium nitrate, 0 to 4 percent of industrial fluorite and 4 to 6 percent of industry pure alkali. The preparation method comprises the following steps of: 1) performing pre-homogenizing treatment on the chrysotile tailing; 2) preparing a mixture; 3) melting glass liquid; 4) performing water quenching and preparing powder; 5) performing press forming; 6) performing crystallization and sintering; and 7) performing demoulding and post-processing. The microcrystal glass prepared by the method is applicable to building, chemical anticorrosion, wear resistant lining for mine and the like. The chrysotile tailing microcrystal glass and the preparation method have a reasonable formula, can effectively improve the comprehensive utilization rate of the chrysotile tailing and reduce environment pollution, and, through harmless phase inversion to the chrysotile tailing, lower the cost for treating chrysotile tailing waste and are beneficial for popularization and application.

Description

technical field

[0001] The invention relates to a glass-ceramic and a preparation method thereof, in particular to a glass-ceramic of chrysotile tailings and a preparation method thereof, belonging to the technical field of treatment and comprehensive utilization of chrysotile tailings. Background technique

[0002] Chrysotile tailings are a kind of waste rock tailings discharged in the process of chrysotile asbestos mining, the main component is serpentine. Due to the low grade of asbestos ore, dozens of cubic meters of tailings must be discharged for every ton of chrysotile produced, which has been stored for a long time and has not been utilized. As we all know, asbestos is a carcinogen, and chrysotile tailings are very harmful to the environment and human body. At present, asbestos waste and asbestos tailings are generally treated by concrete curing, vitrification and sintering curing, etc., and then buried deep after curing. The comprehensive utilization rate of tailin...
