摘要：在对海泡石进行超细加工和粒度分析的基础上，利用X射线分析、红外光谱分析研究了高速气流对撞冲击式超细加工对海泡石的晶体结构所产生的影响。研究发现：高速气流对撞冲击式超细粉碎在完成海泡石纤维束分离的同时，也将对海泡石的晶体结构产生一定的破坏作用，导致海泡石的晶胞参数a、b的减小，基本结构单元间以连续点为支点发生一定程度的旋转，从而产生结构孔道畸变。

Abstract：On the basis of ultrafine processing and size analysis to sepiolite. this paper studiesthat ultrafine processing of high speed air current lash made effect of sepiolite crystal structure byX一ray and IR analysis. We found that ultrafine processing of high speed air current wounddamag crystal structure meanwhile sripping sepiolite fibre. and resulted in crystal constant a、bdccreasing. basic structural unit happened turning. so produced structural channel distortion.
