摘要
采用核微孔滤膜过滤实验、落球粘度计及动态光散射法,研究了非离子型Gemini表面活性剂(GS420)对交联聚合物溶液(LPS)的封堵性能、粘度及交联聚合物线团(LPC)大小的影响。结果表明,加入表面活性剂后,LPS体系对核微孔滤膜的封堵性能降低,但是还能对孔径为1.2μm的核孔膜产生封堵。LPS-GS420复合体系的粘度低于不加表面活性剂的LPS溶液的粘度。动态光散射法测得LPS-GS420复合体系中LPC的平均流体力学半径为190nm,比不加表面活性剂的LPS中的LPC的粒径小。
The influences of nonionic Gemini surfactant（GS420） on the plugging performance, viscosity, and size of the linked polymer coils （LPC） in linked polymer solution （LPS） were investigated by nuclear pore membrane test, dynamic light scattering and dynamic viscosity determination. The results indicated that plugging performance of LPS decreased after addition of GS420, though it was still effective in 1.2 μm nuclepore membrane. Viscosity of LPS-GS420 system was lower than that of LPS. The average hydrodynamic radius （Rh） of the linked polymer coils （LPC） in LPS-GS420 system was 190nm, smaller than that of LPS.
