1-2mm Alumina Bubble Brick Thermal Insulation Filling Material

bubble alumina brick alumina refractory bubble products thermal insulation filling material

Product name:alumina bubble

Specification:0.2-1mm

Properties of alumina hollow spheres :
1, the use of high temperature : the use of temperature up to 1750 degrees or more, good thermal stability. The change rate of reburning line is small and the service life is longer.
2.Saving energy : alumina hollow spheres have good thermal insulation properties, low thermal conductivity, can play a good thermal insulation effect, reduce heat dissipation, improve thermal efficiency, energy saving effect can reach more than 30 %.
3.Saving materials : to achieve the same temperature, the use of alumina hollow balls, per cubic meter can save 1.1-1.9 tons of heavy bricks, but also save 80 % of the refractory insulation materials.
4.Optimize the structure and reduce the weight of the furnace : the alumina hollow ball brick is only 1.1 ~ 1.5g / cm, the same one cubic meter volume, the use of alumina hollow ball brick can reduce 1.1-1.9 tons of weight.

Product Uses
Alumina hollow spheres are high temperature resistant thermal insulation materials, which can be used as raw materials for manufacturing thermal insulation products or directly used as thermal insulation layers for high temperature kilns. Alumina hollow sphere products are made of 70 % alumina hollow sphere and 30 % α-alumina fine powder as raw materials, aluminum sulfate solution as binder, and the body is made by vibration molding. After drying, high temperature firing or light firing products are used according to different conditions. It can be used as high temperature furnace lining, back socks, furnace tubes, trays, and protective covers that are in direct contact with the flame.
