1.Bubble Alumina Brick Description

Bubble Alumina Brick is a kind of energy-saving heat insulation material of ultra-high temperature material. It is made of alumina hollow ball and alumina powder as the main raw materials, combined with other binders, and fired at a high temperature of 1750 degrees.

 

  1. Bubble Alumina Brick Feature

(1)The temperature can reach above 1750 degrees, and the thermal stability is good.

(2)The reheating line has a small change rate and can be used for longer.

(3)It has obvious thermal insulation properties and low thermal conductivity

(4)Reduce heat dissipation and improve thermal efficiency
