摘要 我国的层状硅酸盐含量丰富,据探明我国仅膨润土含量就达23亿吨,分布在十几个省份的400多个矿点。现年开采量仅为200万吨左右。但由于我国工艺技术水平不高、专用设备不配套、产品质量不稳定等原因导致我国的膨润土开发程度低、利用效率低,因此在国际市场上呈现一种"低出高进"的局面,即出口低级产品,进口高级产品。我国出口的钙基膨润土价格为200-300元/t,而进口的有机膨润土价格为1500元/t。因此对我国所有的膨润土进行深度开发是摆在众多科研工作者面前的问题。近年来,我国对层状硅酸盐开发取得了长足的进步。我国科研工作者对其开发主要集中在有机插层、无机插层和聚合物插层三类,在这里对这三种插层、柱撑反应进行一定的分析与研究。 There are a great deal of phyllosilicates, however, because the simple level exploiting and available for a long time, the energy of phyllosilicate don't enough exhibit. The article include the researching resuit of intercalation and pillar supporting of phyllosilicate. So the intercalation phyllosilieates include orangic intercalation,inorangie intercalation and poly intercalation phyllosilieates.
