Refractory high-alumina insulation bricks are a high-quality building material with high thermal insulation performance and good fire resistance. They are widely used in various high-temperature furnaces, heat treatment equipment, industrial furnaces and other places. It is a kind of insulation material made of high-purity bauxite as the basic material. It has the characteristics of light weight, high strength, corrosion resistance and excellent heat insulation performance. It is an indispensable building material in the field of modern construction.
The main components of refractory high-aluminum insulation bricks are high-purity alumina and silicon oxide. These components have strong fire resistance, good high temperature resistance, and can withstand high temperature erosion and the effects of hot and cold cycles. In addition, high-purity alumina and silicon oxide also have good thermal insulation properties, which can effectively reduce heat loss. Therefore, refractory high-alumina insulation bricks are widely used in various high-temperature process industries, such as steel, building materials, metallurgy, chemical industry and other fields, which can effectively improve production efficiency and reduce production costs.
The main features of refractory high alumina insulation bricks are as follows.
Good thermal insulation properties
Refractory high-alumina insulation bricks have good thermal insulation properties, which can effectively reduce heat loss and improve thermal efficiency. At the same time, its density is smaller and its weight is lighter, making it easier to construct and transport.
Outstanding fire resistance
The main components of refractory high-aluminum insulation bricks are high-purity alumina and silicon oxide. These ingredients are non-flammable substances. Therefore, refractory high-aluminum insulation bricks have good fire resistance, can withstand high temperatures, and effectively protect equipment. Extended service life.
Excellent mechanical strength
The material composition of refractory high-alumina insulation bricks is very uniform, its homogeneity is relatively high, and after high-temperature heating treatment, it has good stability and durability. At the same time, its compressive strength and flexural strength are high, and it can withstand certain mechanical shock and vibration.
Good wear resistance and corrosion resistance
The surface of the refractory high-aluminum insulation bricks has been specially treated and has good wear resistance and corrosion resistance. It is not prone to slag, cracking and burning during use, which reduces the frequency of maintenance and replacement, and reduces the cost of cost.
