Detailed Description

Classification Temperature: 1600℃ Description: mullite crystal fiber needle-punching blanket is made of pure mullite fiber through double-sided needle-punching. The product does not contain any bond or other compositions. The temperature can reach to 1450℃ for a long time operating. At this temperature for a long time under oxidizing, neutral or more reducing conditions, mullite crystal fiber needle-punching blanket can still keep its former flexibility, strength, softness and fiber structure. mullite crystal fiber needle-punching blanket has a stronger resistance against acid/alkali-corrosion than common ceramic fiber blanket. 1.Classification Temperature 1600 2.Shrinkage on Heating (%) 1500℃×24h≤-3 3.Thermal conductivity (hot surface 1000℃) W/(m·.k) ≤0.20 4.Density (kg/m3) 96±15;128±15 5.Specification (mm) 7200/3600×610×20/25 other according to customer's requirement 6.AL2O3 (%) 71—73 7.AL2O3+SiO2 (%) ≤99 8.Fe2O3 (%) ≤0.2 9.K2O+Na2O (%) ≤0.2 Packaging Carton Product Characteristics: For it has microcrystal structure, the temperature of mullite crystal fiber blanket can reach to 1450℃ for a long time operating. Low thermal conductivity Little shrinkage below 145℃ Thermal shock resistant mullite crystal fiber blanket is the perfect material to make folding modules; it can still keep flexibility when the temperature is higher than 1450℃. Low heat storage Excellent sound insulation High strength, easy to be processed, No tearing and punching on accessories of anchor parts; Stable chemical properties and anti-corrosive Application: Furnace lining or furnace lining Heat-treatment furnace Ceramic rapid fire furnace High-temperature seal mat Sealing of furnace door High-temperature filtering medium
