| Abstract: | Effect of slag,sugar mud and waste glass on the properties of insulation material were discussed by XRD,SEM and proof tester.The insulation material is prepared that flexural strength,density,pore rate and coefficient of heat conductivity is more than 14 MPa,1.204 g/cm3,35% and less than 0.40 W/(m·K) respectively in the condition of slag 25%,sugar mud 28%,waste glass 14%,clay 33% with forming pressure 20 MPa,firing temperature 1 060 ℃ for 0.5 h.The main crystalling phase in product is mullite and cristobalite and glass phase,gas phase and some anorthite phase were observed.The ratio of closed holes was up to 35%. |
