example 1

[0037] 60kg of gold mine tailings, 10kg of glass-ceramic frit water crushed material, 24kg of nepheline, 5kg of soda ash, and 1.0kg of silicon carbide are mixed and dry-milled until the particle size of the powder is ≤120 mesh. Fill these processed batch materials into refractory containers, and then heat them to 1160°C at a heating rate of 2-4°C / min in the kiln for 40 minutes of heat preservation and foaming; then heat them at a temperature of 10°C / min The temperature is lowered to 950°C at a cooling rate of 1°C / min, then to 550°C at a cooling rate of 1°C / min, and finally to room temperature at a cooling rate of 1-3°C / min.

[0038] The obtained product has an apparent density of 310g / m 3 , the compressive strength is 3.0Mpa, and the thermal conductivity is ≤0.10w / m.k. Finished products cut into standard sizes are packaged for storage.

Abstract

The invention relates to a manufacturing method of a foamed microcrystalline material product by a sintering method. Its technical feature is that the raw material of foamed microcrystalline material products by sintering method is inorganic non-metallic solid waste as the main raw material, which is mixed with additional components such as microcrystalline glass frit water scrap containing crystal nucleating agent. In the production process, firstly, the mixture containing the crystal nucleating agent and foaming agent is prepared by means of mixed grinding, secondly, foaming is performed at high temperature during the firing process, and then the crystallization of the glass phase in the product is controlled by adjusting the cooling curve. The residual glass phase in the foamed microcrystalline material by the sintering method is greatly reduced, so that the material product has sufficient strength. The prepared sintered foamed microcrystalline material has the characteristics of light weight, heat insulation, sound absorption, high strength, etc., and can be widely used in the heat preservation needs of building walls and industrial equipment, and can realize industrial production.

Description
