设计制作了一种用聚四氟乙烯毛细管组成的 Ubbelodhe式粘度计 .将该粘度计试用于测量一个部分水解聚丙烯酰胺试样水溶液在较宽浓度区间直至极稀浓度时的粘度 .与常规玻璃粘度计相比 ,新粘度计避免了在普通玻璃粘度计中测量粘度时由于高分子吸附在毛细管管壁表面引起的干扰 .实验结果表明 ,高分子溶液粘度的所谓“聚电解质效应”仅仅是溶质吸附而引起的表观现象 A Ubbelodhe viscometer with a polytetrafluoroethylene capillary was designed and manufactured.This viscometer was used to measure the viscosity of a partially hydrolyzed polyacrylamide sample aqueous solution over a wide range of concentrations up to a very dilute concentration.Compared with the conventional glass Viscometer compared to the new viscometer to avoid viscosity measurement in the ordinary glass viscometer due to polymer adsorption on the capillary wall surface caused by interference.The experimental results show that the so-called “polyelectrolyte effect” of the viscosity of the polymer solution is only solute Absorption caused by the apparent phenomenon
