| 摘 要： | 为了获得层间距较大的有机蛭石,将蛭石在酸介质中,用十六烷基三甲基溴化铵(CTAB)作阳离子交换剂,以1.5倍阳离子交换容量与蛭石进行阳离子交换反应。通过X衍射实验,将有机化蛭石前后情况进行对比分析。结果表明:蛭石通过有机化之后,层间距由1.76 nm增大至4.01 nm。通过分析之后得出,蛭石有机化的影响因素主要是有机化环境的和蛭石原料形态。

| Abstract: | In order to obtain the layer spacing larger organic vermiculite,the vermiculite in acid medium,using CTAB as cation exchange agent,with 1.5 times the cation exchange capacity of vermiculite and the cationic exchange reaction.Through the X diffraction experiments,will be organic vermiculite and condition carries on the contrast analysis.The results showed that： the organic vermiculite,spacing of layers increases to 4.01 nm by 1.76 nm.Through the analysis that,the main influence factors of vermiculite organic organic environments and vermiculite raw material shape. |
