摘要:

采用低铝莫来石及高压废电瓷为主要原料,添加石英砂粉等外加剂,以纸浆废液为结合剂,通过合理的颗粒级配制成混合物料,经高压成型干燥后于1 400℃烧成制备了低铝莫来石砖。将研制的新型低铝莫来石砖与目前普通的硅莫砖进行性能对比,分析了高压电瓷加入量对烧成试样性能的影响。结果表明:低铝莫来石砖具有低导热性和耐碱性能,更适用于水泥回转窑预热分解带;同时该产品以废高压电瓷为主要原料,对资源的合理利用也有现实意义。

Abstract:

Low aluminum mullite brick was prepared with low aluminum mullite and high-voltage insulator waste as raw materials,quartz powder as additive and pulp waste liquid as binder.The above-mentioned materials were mixed in proper particle size distribution,formed under high pressure,dried and fired at 1 400℃.In the paper,the performances of this new type bricks were compared with normal silica mullite bricks and the effects of the high-voltage insulators waste addition amount on the properties of sintered samples were investigated.The results showed that low aluminum mullite brick has excellent alkali resistant and low thermal conductivity,which is appropriate for the preheating and calcining zone of cement rotary kiln.Meanwhile,the production of the bricks has practical significance for rational utilization of resource as recycling high-voltage insulator waste as raw material.
