摘要

浓悬浮体广泛出现于石油、化工、材料、食品等工业领域中

例如煤浆、油墨、涂料、填充高分子、果酱等.为了解决这些材料的某些工艺问题

常需要了解其流变性质.另一方面

悬浮体理论的发展始于只适用于稀悬浮体的Einstein方程

人们对浓悬浮体复杂的流变行为尚缺乏全面和规律的认识.本文通过对碳酸钙悬浮体流变性能的研究

讨论了分散相浓度和表面改性的影响

得到粒子悬浮体流变性的一些基本认识

亦为各种工业悬浮体的流变表征提供了一种实验方法.

Abstract

A study of the effects of particle content and surface treatment on the rheological properties for calcium carbonate suspensions in a mineral oil was carried out. The result shows that the addition of uncoated particles only increases the viscosity whereas the increase in elasticity

viscoelasticity and non-Newtonian properties is mainly due to the surface modification.
