JM28 Insulation Brick

Description

JM28 Insulation Brick Introduce
 
JM28 Insulation Bricks are made from high purity materials by unique technics, so they have a lot of advantages such as stable volume, excellent thermal stability, high intensity, and low thermal conductivity. They are an ideal kind of energy-conserving products, which can be widely used as linings or as thermal preservations layes in various industrial furnaces and kilns in metallurgical industry, ceramic industry, chemical industry and machinery industry.
 
Application of JM28 Insulation Brick
 
.Glass industries iron & steel industries;
.Ceramics industries non-ferrous metals industries;
.Electrolytic Aluminum industries power generation industries;
.Heat surface fireproof lining other fire-proof back lining.
