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.
Die Refraktärität von JM26 liegt über 1430℃. Die Feuerfestigkeit und der Druck von JM26 sind etwas höher als die von JM23. Es wird üblicherweise für die Auskleidung und Isolierung einiger großer Industrieöfen verwendet.
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.
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!
