Product description of JM23 mullite insulation brick
JM23 mullite insulation brick is made of high-purity mullite, aluminum oxide powder is added according to different models and sintered at high temperature. JM23 mullite insulating brick is a new type of insulating and energy-saving material. JM23 mullite insulating bricks are produced according to German industrial standards, and are particularly suitable for export abroad.
Performance Characters of JM23 mullite insulation brick
- Low thermal conductivity and good thermal insulation effect
- The mullite insulating brick has low heat fusibility. Due to the low thermal conductivity, mullite series lightweight insulating bricks have less heat energy stored and have obvious energy-saving effect in intermittent operation.
- The content of impurities is low, and the content of iron box alkali metal and other oxides is extremely low, so the fire resistance is high; High aluminum content, which makes it maintain good performance in reducing atmosphere
Application of JM23 mullite insulation brick
JM23 mullite insulation bricks are widely used for insulation of various industrial furnaces. Such as electric furnaces, metallurgical furnaces, petroleum cracking furnaces, metallurgical hot blast furnaces, ceramic roller kilns, tunnel kilns, electric porcelain shuttle kilns, glass industry kilns, various electric furnaces and linings of high-temperature equipment.
