High Temperature Insulating Fire Brick J26 Jm32 Thermal Lightweight Refractory Insulation Brick¹

Product Description Product DescriptionMullite insulation bricks are high alumina refractory materials with mullite (3Al2O3·2SiO2) as the main crystal phase. Generally, the alumina content is between 65% and 75%. In addition to mullite, the mineral composition contains a small amount of glass phase and cristobalite in the lower alumina content, and a small amount of corundum in the higher alumina content.Mullite insulation bricks can be directly used in the lining of high-temperature kilns. At present, they have been widely used in the lining of shuttle kilns, roller kilns, glass and petrochemical kilns.Features1. Low thermal conductivity, good thermal insulation effect;2. Low thermal fusion, due to the low thermal conductivity, the mullite series light insulation bricks accumulate little heat energy, and the energy saving effect is obvious in intermittent operation;3. The low impurity content has a very low content of oxides such as alkali metal in the iron box, so the refractoriness is high; the high aluminum content makes it maintain good performance under a reducing atmosphere;4. High compressive strength in hot state;5. Accurate appearance and size, speed up the masonry speed, reduce the amount of refractory mud, ensure the strength and stability of the masonry, and thereby extend the life of the lining;6. Can be processed into special shapes to reduce the number of bricks and the joints.BrandPropertiesJM-23LDJM-23JM-26JM-28JM-30JM-32              Classification temperature (oC)130013001400150015501600                        Bulk Density (g/cm3)0.550.60.80.91.01.1                 Cold Crushing Strength (MPa)1.01.21.82.53.33.5                   Modulus of rupture (MPa)1.01.01.72.33.13.2  (CToCX24h) Permanent Linear Change (%)      -0.40.60.60.80.91.01@ 1,100oC  Thermal Linear Expansion (%) 0.500.500.520.520.530.7Thermal conductivity (W/m.k)350oC0.140.180.270.320.380.49400oC0.150.200.290.340.400.5600oC0.170.240.320.360.420.51 (%) Chemical Analysis Al2O3384056677377Fe2O30.8 (CaO12%)1.00.80.70.70.5Q1 : How can you control your quality?A1 : For each production processing, we have complete QC system for the chemical composition and Physical properties.
