研究了水解聚丙烯腈铵盐（ＮＰＡＮ）对粘土颗粒、ＭＭＨ胶体粒子和ＭＭＨ／粘土复合体粒子电泳淌度的影响，发现ＮＰＡＮ能极大地增加粘土颗粒的负电性，说明ＮＰＡＮ在粘土颗粒表面发生了吸附作用；ＮＰＡＮ不仅能够削弱ＭＭＨ胶粒的正电性能，浓度足够大时甚至使ＭＭＨ胶粒由荷正电变为荷负电；ＭＭＨ／粘土复合体粒子电泳淌度的变化则是由于ＮＰＡＮ在粘土颗粒和ＭＭＨ胶粒上的共同吸附引起的。本文还研究了ＮＰＡＮ对ＭＭＨ／粘土体系流变性能的影响，认为ＮＰＡＮ在ＭＭＨ胶粒和粘土颗粒上的强吸附作用拆散了ＭＭＨ／粘土体系的网架结构，导致体系ＡＶ和ＹＰ降低。ＮＰＡＮ虽然能增加粘土颗粒的负电性，但是ＭＭＨ对含ＮＰＡＮ的粘土体系的增稠作用随ＮＰＡＮ加量的增加而削弱，说明ＭＭＨ胶粒与粘土颗粒的相互作用不宜简单地看作静电相互作用。
The effect of NPAN on the particle electrophoretic mobility of clay particles, MMH colloidal particles and MMH / clay composites was investigated. It was found that NPAN greatly increased the negative charge of clay particles, indicating that NPAN occurred on the surface of clay particles NPAN can not only weaken the positive charge of MMH colloidal particles, but also make MMH micelles change from negative charge to negative charge when the concentration is large enough. The variation of particle electrophoretic mobility of MMH / clay complex is due to NPAN Clay particles and MMH colloidal particles caused by co-adsorption. The effect of NPAN on the rheological properties of MMH / clay system was also studied in this paper. The strong adsorption of NPAN on MMH colloids and clay particles dismantled the network structure of MMH / clay system, resulting in the decrease of AV and YP. Although NPAN can increase the negative charge of clay particles, the thickening effect of MMH on the NPAN-containing clay system is weakened with the increase of NPAN content, indicating that the interaction between MMH particles and clay particles should not simply be regarded as electrostatic interaction.
