摘要
采用ＢｒｏｏｋｆｉｅｌｄＲＶＴ型旋转粘度计测定粘度，研究缔合型增稠剂的流变性。将粘度数据进行计算机处理，回归出Ｃａｓｓｏｎ方程，获得屈服值和无穷大剪切粘度，以描述增稠体系的遮盖力、稳定性、流平性、抗流挂性、抗沉降等，并测定了耐电解质性和后增稠性。通过对粘度的测定，提供了一种综合评价增稠剂应用性能的途径。
AbstractThe rheology of the associated thickeners has been in-vestigated by use of Brookfield RVT viscometer forviscosity measurement. The data of viscosity wasprocessed with computer and a regression Cassonequation was derived to calculate the yield value andinfinitive shear viscosity that can be used to featurethe hiding power, stability, leveling, sagging andsedimentation of viscous liquids. The electrolyte re-sistance and after viscosity increase were determined.The study has provided a comprehensive evaluationapproach for the performance of thickeners.
