Abstract

The invention belongs to the field of refractory, especially relates to a mullite light-weight micropore thermal insulation brick and provides a new formula of the mullite light-weight micropore thermal insulation brick. The constituents of the mullite light-weight micropore thermal insulation brick include Guangxi mud, kyanite, alumina powder, a scrap material of the same type, carbon black and anthracite. The compressive strength of the product with the same bulk density is about 25% higher than that of the like product, and the thermal conductivity is lower than that of the like product by more than 50%. The insulation effect is better, thereby being conducive to energy-saving and emission reduction. At the same time, the new formula of the mullite light-weight micropore thermal insulation brick provided by the invention is more conducive to the control of the technical process and the product quality compared with other formulas.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a formula of mullite lightweight microporous thermal insulation brick. Background technique [0002] Mullite is a kind of aluminum-rich mullite, colorless, columnar or needle-shaped crystals, melting temperature is 1840 ° C, mullite is mainly aluminosilicate minerals, and its natural minerals rarely exist in the earth's crust, because first It was found in the Isle of Mullite, Scotland, so it is called mullite. However, artificial mullite is indeed a common and widely used mineral. The chemical composition of mullite is not stable. The common one is 3Al 2 o 3 .2SiO2 2 and 2Al 2 o 3 .SiO 2 Two forms. Mullite is a high-quality refractory material, which has the characteristics of uniform expansion, excellent thermal shock stability, high load softening point, small high temperature creep value, high hardness, and good chemical corrosion resistance. The tradit...
