本文讨论了用三种仪器(落球粘度计,圆筒式旋转粘度计,毛细管挤出流变仪)相结合的方法,在γ=0—10~4(秒~(-1))范围内准确测定非牛顿流体粘度的方法。选用聚甲基丙烯酸甲酯、聚苯乙烯、聚丙烯酰胺等高分子溶液为样品,得到连贯的粘度一切速率曲线,强调了为得到准确的结果须特别注意的试验及数据处理的要点及各种方法的适用范围。 This article discusses the combination of three instruments (falling ball viscometer, cylindrical rotating viscometer, capillary extrusion rheometer) in the range of γ = 0-10 ~ 4 (s -1) Methods for determining the viscosity of non-Newtonian fluids. The selection of polymethyl methacrylate, polystyrene, polyacrylamide and other polymer solution as a sample to obtain a consistent viscosity of all rate curves, stressed the precise results to be paid special attention to the test and data processing points and various The scope of the method.
