蒙脱石

It is found that quaternary ammonium salt and alkylamine can react with montmorillonite and rectorite via cation exchange reaction and the resulting OMMT and OREC can act as nano-scale filler to PPC materials due to its increasingly swollen gallery spacing.

主要研究结果如下：(1)采用阳离子交换法，制备了不同的有机胺改性的有机蒙脱土和有机累托石，用XRD， FTIR， TGA表征了插层效果。

Over the pillared saponite by the impulse reaction, while it was only ～4％ for the pillared montmorillonite, indicating that the substitutions in the tetrahedral sheets played an important role in the development of Bronsted acidity of the catalyst.

层柱皂石的异丙苯裂解转化率达到了65％；而层柱蒙脱土的转化率只有4％。这说明层材料的四面体取代对于层柱粘土Bronsted酸位的形成具有重要的决定作用。

The experimental method and reaction conditions for synthesis of acetals and ketals on more than 40 catalysts such as solid superacids、 heteropoly acids、 con-exchange、 resins、 molecular sieves、 niobic acid、 vitamin C、 iodine、 sulfate、 chloride、 montmorillonite and etc.

综述了固体超强酸、杂多酸、固载杂多酸、脱铝超稳沸石、树脂、分子筛、铌酸、漆酚衍生物、维生素C、碘、硫酸盐、氯化物、蒙脱土等40多种催化剂催化合成缩醛的方法和反应条件。

I produced magnesium silicate gel inorganic mineral is magnesium-rich smectite and montmorillonite by the exploitation of special purification, modified, modified from refined processing.

我公司生产的硅酸铝镁盐无机矿物凝胶是由富镁蒙皂石和特殊的蒙脱石经开采纯化，改型，改性加工精制而成。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
