摘要
粉煤灰磁珠具有较强的磁性,同时又具有特殊的多孔微珠结构,因而拥有较高的资源化利用价值。在对粉煤灰磁珠的微观结构及理化性质总结的基础上,对粉煤灰磁珠在重介质选煤、污水处理、功能复合材料等领域中的应用研究进行了综述。进而提出磁珠精细分级、分类资源化的新思路,并分析了磁珠资源化研究的发展方向。
Fly ash magnetic micro-spheres have great resource utilization potential for their ferromagnetism and special micro-sphere structures.The research progress of the fly ash magnetic micro-spheres applications in dense medium separation,wastewater treatment,and functional composite are reviewed,based on the summarization of the microstructure and the physico-chemical property of fly ash magnetic micro-spheres.Furthermore,apromising utilization method of magnetic micro-spheres based on fine classifying and classified application are proposed.The development orientation of magnetic micro-spheres resource utilizations is discussed.
