Modification and Deep Progressing of Diatomite and Its Applications

本文介绍了硅藻土的起源、结构、性质,综述了国内外硅藻土产品在助滤剂、填料、建筑材料与保温隔热材料、载体方面的应用现状。重点从水处理、橡胶、多孔陶瓷、沥青、造纸、新型建筑材料等方面对硅藻土的深加工利用研究进展进行了综述,并对硅藻土的未来发展进行了展望。

This paper simply introduced the origin, structure and properties of the diatomite, and reviewed the present domestic and international application of the diatomite from the filter aid agent, packing, building materials, thermal insulation materials and carrier aspects. Moreover this paper mainly reviewed the application progress of the modified diatomite and the research progress of deep progressed diatomite from the preparation of rubber, porous ceramics, asphalt, paper and new building materials aspects. Finally we look forward to the future of development prospects of the diatomite.
