    The density of insulation firebrick is 0.60~1.25g/cm3, and the working temperature is 900°C to 1600°C. Insulation firebrick can reduce the cost of the foundation, reduce the cross-section of the frame, and save reinforced concrete can significantly save the comprehensive cost of the building. Compared with solid clay bricks, the overall cost of using lightweight bricks can be reduced by more than 5%. Lightweight bricks have good work ability and are easy to construct.

  • Alumina bubble brick

    Alumina bubble brick

    Alumina bubble brick is one of the ultra-high temperature material energy-saving insulation materials. It uses alumina hollow spheres as the main raw material and combines with other binders to fire alumina hollow spheres in a high temperature furnace at 1750. Alumina bubble brick has the characteristics of low thermal conductivity, good heat preservation, high compressive strength, and can work at temperatures below 1800°C. It has excellent heat resistance and heat insulation properties, and excellent energy saving.
