Description
Technical Field
The invention belongs to the field of building materials, and particularly relates to a composite insulating brick.
Background
The heat efficiency of industrial activation furnaces in developed countries in the west is generally 30% -40%, while the heat efficiency of industrial activation furnaces in China is only 25% -35% on average, so that the heat efficiency of the activation furnaces is improved, and the realization of energy conservation and emission reduction has important significance for reducing energy pressure, reducing production cost and protecting environment. The commonly used materials of the present activation furnace include a silicon-aluminum sintered refractory material and an electric melting zirconia corundum refractory material. The silicon-aluminum refractory material has light dead weight, effectively reduces the load bearing, but has poor heat preservation effect, is easy to delaminate and peel off, pollutes glass liquid, influences the product quality, and has great harm to high-quality products; the fused zirconia corundum refractory material has the advantages of high temperature resistance, chemical erosion resistance, stripping resistance and long service life, but has the defects of heat dissipation, no heat preservation, large self weight and increased load bearing.
At present, in order to pursue a large heat insulation effect, a heat insulation material in the prior art generally achieves the purpose of reducing heat conductivity and realizing heat preservation by increasing the porosity and porosity of the material. However, the high porosity and porosity inevitably result in lower strength of the material, which is not only easy to damage and dissipate in use, affecting the service life of the material, but also easily causes impurity elements in the product, affecting the quality of the product. It is common in the prior art to develop different types of refractory materials, such as selected from siliceous, aluminous, magnesian materials; meanwhile, the strength and the heat-insulating property of the material are balanced by various compounding formulas. However, in order to achieve a certain strength in the actual production process, a part of the porosity and the air porosity has to be lost, which in turn reduces the heat insulation effect.
