Alumina Bubble Brick Introduction
Alumina bubble brick adopt alumina hollow ball and alumina powder as main material, combined with other bonding agent, it belongs to one of the hyperthermal saving and insulating material. Alumina hollow ball bricks is kind of light weight refractory material with high temperature resistance and excellent energy saving, which are very stable in various atmospheres.
Alumina hollow ball insulating refractory brick is a kind of new high temperature insulating material,it is produced with smelted and blown in electric furnace, the crystal form is a-Al2O3 microcrystal. Take the alumina hollow sphere as the main body, and it can be made into various shapes. The highest use temperature is 1800 degrees, and the product has high mechanical strength.
Alumina Bubble Bricks Properties
- High operating temperature, which can reach above 1750 degree.
- Alumina bubble brick cam effectively reduce the weight of the furnace body.
- Good thermal insulation
- Low thermal conductivity
- Reduce heat emission and improve thermal efficiency, thereby realize the purpose of saving energy. The energy saving effect is more than 30%.
