| 摘 要： | 金洋、蒙西和雪纳高岭土化学成分以SiO2和Al2O3为主，K、Na、Ca、Mg含量低，而Fe、Ti含量较高；矿物成分以高岭石为主，还含有少量一水软铝石、石英、蒙脱石等。XRD和IR分析结果表明，金洋和蒙西高岭石的有序度较高，HI结晶指数分别为1.19和1.23，而雪纳高岭石的衍射峰峰形弥散，对称程度差，HI结晶指数仅有0.56。二甲基亚砜和甲酰胺与煤系高岭土相互作用后均能进入高岭石层间并撑大其晶面间距，其中金洋高岭土的插层率最高，雪纳次之，蒙西高岭土的插层效果最差。

| Abstract: | The chemical composition of kaolin in coal measures of Jinyang, Mengxi and Xuena is SiO2 and Al2O3 with low content of K, Na, Ca and Mg and relatively high content of Fe and Ti. The mineral composition is mainly kaolinite with minor boehmite, quartz and montmorillonite. The XRD and IR analytical results reveal that kaolinite in Jinyang and Mengxi exhibits a highly ordered structure with HI index being 1.19 and 1.23, while kaolin from Xuena shows dispersed and low symmetry diffraction peaks, with HI index being only 0.56. On such a basis, kaolin_dimethyl sulfoxide and kaolin_formide intercalation composite was prepared. The XRD patterns indicate that dimethyl sulfoxide and formide can insert into the inter layer of kaolinite and increase the interplanar spacing. Kaolin from Jinyang has the best intercalation ratio, kaolin from Xuena takes the second place, and kaolin from Mengxi is the worst. |
