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 uses high-purity materials, adding high-temperature stabilizers and corrosion-resistant materials. Thus further increasing the density and compressive strength. It is often used in lining and insulation layers of high-temperature industrial kilns.
