Abstract:

Diatomite as a kind of biogenic siliceous sedimentary rock is widely distributed in the world, but less with high economic values. China, abundant in diatomite resource, is one of major diatomite producers. In diatomite product structures, however, China has a big gap. As power saving and environment requires, China's diatomite product structures will be largely improved. The dominant developing trends for the diatomite industry include top-quality diatomite filtration, functional fillings and compound materials, insulation materials, water treatment agents and absorbent, and purification materials. China's diatomite industry must focus on extensive utilization, renovation and industrial platform construction.

摘要：

硅藻土是一种生物成因的硅质沉积岩，在世界上广泛分布。但是，可供直接开发利用、经济价值较高的矿床却很有限。中国硅藻土资源优势明显、储量丰富，是硅藻土的主要生产国。在硅藻土产品结构上，中国与国外还有相当大的差距，随着全球性节能、环保要求的提高以及中国工业的发展和硅藻土产业自身的技术进步，中国硅藻土的产品结构必将发生重大变化；主导性的产业发展方向有主流型——高质量的硅藻土助滤剂、高效型——功能性填料和复合材料、节能型——中高档保温隔热材料、环保型——水处理剂和吸附剂与潜力型——原土提纯系列。中国硅藻土产业发展要重视以下几点对策与建议：①坚持集约增效，促进持续发展；②依托科技创新，实施品牌战略；③实施系统工程，加强平台建设。
