| 摘 要： | 本文采用搅拌法测量氯化聚乙烯（ＣＰＥ）及氯化聚乙烯（ＣＰＥ）接枝（－ｇ－）氯乙烯（ＶＣ）悬浮液的粘度，与含固率建立关系，用Ｍｏｏｎｅｙ和Ｒｏｂｉｎｓｏｎ方程式进行关联。由悬浮液表观粘度ηａ与含固率ψｖ的关系曲线得出临界含固率ψｃ，结果发现ψｃ与悬浮液沉降层体积Ｖｐ呈线性关系：ＣＰＥ：ψｃ＝－０．４５５Ｖｐ＋１．４５６；ＣＰＥ－ｇ－ＶＣ：ψｃ＝－０．１８６Ｖｐ＋０．７５２

| Abstract: | Suspension viscosities of chlorinated polyethylene (CPE)and CPE-g-Vingl Cholride(VC)were determined by use of a definite agitator, which is considered to have the same Power Number(Np)Reynolds Number (N((Rc)) relation for various fluid systems.They were correlated with the solid phase fraction (v) and modelled by Mooney and Robinson equations.Critical solid phase fraction(c) was obtained and interrelated with precipitated phase volume (Vp) in CPE and CPE-g-VC suspension.Linear relationship between c and Vp was found as follows:CPE c=-0.455Vp+ 1.456CPE-g-VC c= 0.186Vp+ 0.752 |
