Performance and application of mullite insulation brick:
This series of products adopt high purity raw materials and unique manufacturing technology to avoid the influence of impurities and structural defects on the properties of the products to the maximum extent. It has excellent high temperature volume stability and thermal shock stability, and has high strength and low thermal conductivity. It can be used in metallurgical, mechanical, ceramic, chemical and other industries, such as kiln lining (not to be corroded by molten liquid) and insulation layer. It is an ideal product.
Features:
1.Low thermal conductivity, good thermal insulation effect;
2.Refractoriness is as high as 1750 ºC
3.Mullite Insulating bricks can save you heat and a lot of money.
4.Mullite insulation brick can lighten the weight.
5.It can be processed into special shape to reduce the number of bricks and joints.
