钼尾矿和粉煤灰属大宗固体废弃物,长期大量堆存对生态环境危害巨大.为解决此问题,以钼尾矿和粉煤灰为原料,偏高岭土为调节剂,碱激发制备无机矿物聚合物材料,旨在实现这两种固体废弃物的高附加值利用,并降低其对生态环境的破坏和污染.通过单因素试验确定了无机矿物聚合物的最佳配比和制备工艺,所制备的无机矿物聚合物材料的 7d抗压强度为 27.79 MPa,吸水率为 2.18%,密度为 2.34 g/cm3.XRD图谱分析结果表明,制得的聚合物材料中,无机矿物聚合物占一定比例.聚合物材料在免烧砖、人造石装饰材料、基材修补材料等方面具有广阔应用前景.
Preparation of Inorganic Mineral Polymer Materials from Molybdenum Tailings and Fly Ash
Molybdenum tailings and fly ash pertain to bulk solid waste,which pose great harm to the ecological environment due to long-term and large-scale storage.Research has been conducted on the preparation of inorganic mineral polymer materials using molybdenum tailings and fly ash as raw materials,metakaolin as a regulator,and alkaline activation.The aim is to achieve high value-added utilization of these two solid wastes and reduce their damage and pollution to the ecological environment.The optimal ratio and preparation process of inorganic mineral polymers were determined through single factor experiments.The 7 d compressive strength,water absorption ratio,and density of the prepared inorganic mineral polymer material were 27.79 MPa,2.18%,and 2.34 g/cm3,respectively.The XRD pattern analysis results showed that a composite material with a certain proportion of inorganic mineral polymers was prepared,which has broad application prospects in non-fired bricks,artificial stone decorative materials,substrate repair materials,and other fields.
