90% Al2O3 White high strengh Alumina bubble Insulating refractory brick for
high temperature kilns
Alumina bubble bases on alumina bubble as the main body and can be made into various shapes, the highest operating temperature can reach 1800 ℃, the product with high mechanical strength which is general light products several times, and the bulk density is only half of the corundum products. Alumina bubble is a new kind of high temperature heat insulation material.
Alumina bubble Insulating refractory brick uses alumina bubble and alumina powder as the main raw material, combined with other binder, through 1750 degrees high temperature firing which is a kind of ultra-high temperature energy-saving insulation materials. Alumina bubble brick can be used for high temperature kilns such as shuttle kiln.
Alumina bubble Insulating refractory brick Features:
1. High operating temperature can reach over 1750 degrees.
2, Good thermal shock resistance, small reheat linear change and durability.
3, Small volume density: Commonly used refractory materials belong to heavy bricks with volume density generally 2.6-3.0 g/cm3, alumina bubble brick only 1.1-1.5 g/cm3, thus reducing 1.1-1.9 tons per volume.
4, Obvious thermal insulation properties, low thermal conductivity which have very good heat preservation effect and can increase thermal efficiency.
5, Reduce heat dissipation,, thereby achieve the purpose of saving energy. The energy saving effect can reach more than 30%.
