The temperature and thermal shock resistance are relatively good. 1. High temperature strength; 2. Good insulation performance; 3. Resistant to corrosion in various atmospheres; 4. Significant energy-saving effects and other characteristics; 5. Excellent thermal shock stability performance. It is an ideal energy-saving product for kiln linings (not corroded by solutions) and insulation layers used in industries such as metallurgy, machinery, ceramics, and chemical engineering. Its operating temperature is below 1350C Body embarrassment, dense load, Qinhua enlightenment, heat education WM K degree temperature storage and H strong weight change initial temperature grade s FE2034E G/CM3l degree MPA, ℃ 4629% 6% c0.1MPA) 8ooc p 200c 400c method PD-o.86o1 0.8 1400x12 0.32 1400c PD-1.06o116.5 1400x12O.28 0.3 0.35 1400c PD-1.26ol 8 1400x12 0.38 0.4 0.44 1450c high alumina polyimide insulation brick has an AL203 content of over 48%, mainly composed of mullite and glass phase or corundum as a lightweight refractory material. The volume density is 04~135glom3, the gas content is B6%~73%, the compressive strength is 1~AMPa, and the refractory temperature is 1500. High alumina lightweight insulation bricks, also known as high alumina lightweight ball bricks, are produced using special grade blast furnace materials as the main raw materials, supplemented by appropriate admixtures, and the poly light burning loss method. The product has advantages such as high strength, good thermal stability, small changes in heavy burned fibers, and low thermal conductivity. High alumina polylight bricks are used. High alumina polylight bricks have reached various technical indicators of similar products and are currently a necessary new material in industrial kiln design.
