摘　　要：为了改善陶瓷固废资源制备的耐火材料抗碱侵蚀性能,实现固废资源的高值利用,本文研究了废高铝瓷球原料与碳酸钾的作用行为,分析了铝硅系材料碱侵蚀机理,重点探讨了在以废高铝瓷球为主的免烧浇注料中,添加不同量废棚板对其抗碱侵蚀性能的影响。研究结果表明:由于废棚板细粉的引入,在以废高铝瓷球为主的免烧耐火材料基质中形成屏蔽结构,将骨料包覆起来,与渗透的碱相隔离,起到了有效抵抗碱侵蚀作用。并且随着废硼板加入量的增加,以废高铝瓷球为主的免烧耐火材料的抗碱侵蚀性能更优。In order to improve the alkali erosion resistance of refractories prepared from ceramic solid waste resources and realize the high-value utilization of solid waste resources, the action behavior of waste high alumina ball raw material and potassium carbonate was studied, and the alkali erosion mechanism of aluminum silicon materials was analyzed. The relationship between the amount of waste shed board and the resistance to alkali corrosion was discussed. The results show that due to the introduction of fine powder of waste shed board, a shielding structure is formed in the matrix of unburned refractory mainly composed of waste high alumina ceramic balls, which covers the aggregate and separates it from the penetrated alkali, so as to effectively resist alkali erosion. With the increase of the addition amount of waste shed board, the alkali attack resistance is better.
