环境友好型耐火材料的研究进展

Progress in Research on Environment-Friendly Refractories

随着我国环保意识的日益增强,一些性能优良但是对人体和环境会产生不利影响的传统耐火材料受到挑战。近年来,提出了环境友好型耐火材料这一崭新的理念。环境友好型耐火材料就是要求耐火材料在生产过程中不使用有损于环境和人体的致癌物质和有毒物质,施工过程中不产生大量的粉尘,使用过程中不产生有害气体和有毒物质,使用后的残留材料应具有再生价值,不能成为工业垃圾。主要针对国内外近年来在环境友好型耐火材料的开发上取得的进展进行了汇总,综述了新型无氟耐酸料、无铬耐火材料、新型生物可溶性耐火纤维、低温碳素捣打料和湿法无尘喷涂料等环境友好型耐火材料,以推进我国耐火材料行业的发展。

With enhanced increasing of environmental protection consciousness in China, some traditional refractories with good performance but bad for human beings and environment were challenged. The new idea of environment-friendly refractories was put forward in recent years. Environment-friendly refractories meant that carcinogenic substance and toxic substance which were bad for environment and human beings were not used in the production process, lots of dust were not produced in construction process, harmful gas and toxic substance were not produced in application process, and used re- sidual materials should be with recycle value and not be as a kind of industrial refuse. Progress of development of environ- ment-friendly refractories at home and abroad was collected in this paper, and the current status of some environment- friendly refractories such as new fluoride-free acid resistant material, chrome-free refractories, new bio-soluble refractory fiber, low temperature carbon ramming mix and wet and dust-free gunning mix were overviewed, in order to promote the development of refractory industries in China.
