Preparation of Light-Weight Forsterite Insulation Materials Through Extrusion Processing

摘要：

　　Light-weight insulation materials were prepared by extrusion processing using forsterite raw tailings,light-burned magnesia and fused magnesia as main raw materials with addition of rice hull powder as a pore-forming agent.The results show that the plasticity of green compact and the cold compressive strength of bricks are improved with the addition of 2-3 wt% dextrin as plasticizer.Light weight insulation materials,which meet different application requirements,were prepared by controlling the addition amount of rice hull powder by firing at 1550 ℃ with volume weight of obtained materials varies from 1.4-1.8 g/cm3,thermal conductivity at 600 ℃ is less than 0.48 W/(m·K),cold compressive strength varies from 8-24MPa and reheating linear change rate is less than 1% (1400℃ × 6h).
