ChinaMulliteInsulationBrick Description K23 JM23 Mullite Insulation Brick uses high-purity mullite as raw material, and adds different amounts of aluminum oxide powder according to different types. The product is calcined at high temperature, so it has excellent high temperature resistance. This brick is a new type of energy-saving and thermal insulation material, which will not volatilize toxic and harmful substances even in high temperature, so you can use it safely. The product has high hot compressive strength and low thermal conductivity, so it has good thermal insulation effect. The product contains less impurities, so it has high fire resistance. Due to the low thermal conductivity, the product has less heat energy accumulation, so the energy-saving effect is obvious. Features 1. The product has light weight and high dimensional uniformity, so it can greatly accelerate the masonry speed and reduce the use of refractory mud. 2. The product has high hardness and strength, so it can ensure the strength and stability of the masonry, thus extending the service life of the furnace and other equipment. 3. K23 JM23 Mullite Insulation Brick is mainly used in hot blast furnaces, glass furnace regenerators, ceramic sintering kilns, petroleum cracking systems, etc. 4. The low thermal conductivity makes the product have good thermal insulation effect and high fire resistance. The high aluminum content makes it still maintain good performance in reducing atmosphere.
