| 摘 要： | 通过线性膨胀、粒度分布和Zeta电势的测定，研究了聚乙二醇(PEG)、十二烷基苯磺酸钠(SDBS)及其复配体系对蒙脱土水化膨胀和分散作用的影响．结果表明，PEG／SDBS复配体系具有显著的抑制蒙脱土水化膨胀和分散的能力，改善并降低了温度对蒙脱土水化膨胀和分散的影响；结果还表明，线性膨胀实验和粒度分布实验具有同一性;即抑制性越强，越容易使蒙脱土颗粒聚集．

| Abstract: | The inhibition of polyethylene glycol (PEG), sodium dodecylbenzylsulfonate (SDBS) and their complexes on aqueous montmorillonite dispersions was investigated by linear swelling, size distribution and Zeta potential measurements. It is concluded that PEG/?SDBS complexes have excellent ability to inhibit swelling and dispersion of montmorillonite, reduced the effect of temperature. It is also shown that linear swelling and size distribution experiments have good identity; that is, the stronger the inhibition is, the easier it is to make montmorillonite particles aggregate. |
