Mullite insulation bricks, also known as mullite lightweight bricks, are refractory materials with aluminum silicate as the main component. The alumina content is between 40% and 77%, and it has excellent thermal insulation performance. Mullite bricks can directly contact flames, with a volume density of 0.55~1.35g/cm3 and a compressive strength of 1.2~4.5Mpa.
Mullite insulation brick is mainly composed of mullite and a small amount of binder, it is white, the alumina content is between 38% and 44%, and the refractoriness is 1350°C. It is used as the inner lining and insulation layer of small and medium-sized industrial kilns.
The refractoriness of JM26 is above 1430℃. The refractoriness and pressure of JM26 are slightly higher than that of JM23. It is commonly used in the lining and insulation layer of some large industrial kilns.
JM28 使用高纯度材料，添加了高温稳定剂和耐腐蚀材料。从而进一步提高了密度和抗压强度。它常用于高温工业窑炉的内衬和隔热层。
JM30 has the highest density and the highest service temperature is 1650℃, which is suitable for some extremely high-temperature industrial kilns. Kerui provides various types of mullite insulation bricks. Welcome to inquire!
