摘要
通过XRD、SEM和强度测试技术等分析手段探讨了炉渣、废玻璃、糖滤泥不同固体废弃物对保温材料形成和性能的影响。结果表明,以炉渣质量分数25%、糖滤泥质量分数28%、废玻璃质量分数14%、水曲柳质量分数33%,在成型压力为20MPa、烧成温度1 060℃、保温时间0.5h下,可制备出抗折强度大于14MPa、密度为1.204g/cm3、孔隙率达到35%、导热系数小于0.40 W/(m.K)的陶瓷保温材料。物相组成分析其制品成分主要晶相为莫来石、方石英,同时存在玻璃相、气相以及少量钙长石相。SEM观察其微观结构制品中有大量气孔存在,气孔所占体积比可达35%,气孔呈封闭状态。
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%.
