摘要
以工业垃圾废岩棉和废玻璃为原料,以CaCO3为发泡剂制备出高强度泡沫玻璃陶瓷.研究了废岩棉和废玻璃的添加量及烧结温度对泡沫玻璃陶瓷材料性能的影响.结果表明:随着废岩棉添加量的增加和烧结温度的提高,熔体黏度会降低,不利于气泡结构的稳定;在废岩棉添加量为40%、750℃烧结温度下得到的样品容重为0.54 g/cm3、孔隙率为62.5%、抗压强度为4.76 MPa;样品主晶相为亚硅酸钙和石英晶相,加入TiO2作为晶核剂后主晶相改变为榍石;TiO2掺量为10%时,在750℃烧结20 min更经济,所得样品容重为0.82 g/cm3、孔隙率为50%、抗压强度为7.76 MPa.
Abstract
High strength foam glass ceramic were prepared with industrial waste rock wool and glass as raw materials and CaCO3 as foaming agent.The effects of the proportion of waste rock wool and waste glass and sintering temperature on the properties of foam glass ceramic were studied.The results showed that the melt viscosity was decreased with the increase of waste rock wool and sintering temperature,which was not conducive to the stability of the bubble structure.At a 40%waste rock wool content and a sintering temperature of 750℃,the sample was obtained with a bulk density of 0.54 g/cm3,a poros-ity of 62.5%,and a compressive strength of 4.76 MPa.The samples were mainly formed into wollastonite and quartz crystal phases.After adding TiO2 as the nucleating agent,the main crystal phase was changed to titanite.When TiO2 content was 10%,it was more economical to sintering at 750℃for 20 min.The bulk density of the sample was 0.82 g/cm3,the porosity was 50%,and the compressive strength was 7.76 MPa.
