利用不锈钢渣制备微晶玻璃的研究进展

Research Progress on Preparation of Glass-Ceramics from Stainless Steel Slag

工业的快速发展导致固体废弃物逐年增加,由其带来的环境与资源问题不容忽视。利用工业固体废弃物制备微晶玻璃材料是固废资源化利用的重要途径之一,同时,该方法还可实现有害重金属元素的固化,减少环境危害。本文基于不锈钢渣的来源与特性,对比分析了不锈钢渣无害化处理的常见方法。针对不锈钢渣的无害化处理和资源化利用问题,重点综述了利用不锈钢渣制备微晶玻璃过程中主要成分对材料结构与性能的影响;另外,基于微晶玻璃对重金属元素的固化研究现状,重点讨论了微晶玻璃对不锈钢渣中Cr、Ni、Mn重金属元素的固化;最后对不锈钢渣无害化处理与资源化利用的未来研究方向进行了展望。

The rapid development of industry leads an increase in solid waste production year by year,and the environmental and resource issues it brings cannot be ignored.Using industrial solid waste in the form of glass-ceramics is one of the important ways of solid waste resource utilization.At the same time,this method can also reduce environmental damage by solidifying heavy metals.Based on the sources and characteristics of stainless steel slag,the common methods of harmless treatment of stainless steel slag are compared and analyzed.In view of the harmless treatment and resource utilization of stainless steel slag,this paper focuses on the influences of main components on the structure and properties of glass-ceramics in the process of preparing glass-ceramics materials from stainless steel slag.In addition,based on the research status of solidification of heavy metals by glass-ceramics,the harmless treatment of Cr,Ni and Mn in stainless steel slag cured by glass-ceramics is analyzed and discussed.Finally,the future research directions of harmless treatment and resource utilization of stainless steel slag are prospected.
