悬浮液的粘度受多种因素的影响，包括固体的形状、尺寸、尺寸分布、浓度、密度和表面特性以及悬浮介质的粘度。报道了颗粒浓度“2”~形状“~”~“~”、粒径“~*”分布和剪切速率“~”对悬浮液粘度的影响。在适当的环境中，表面电荷会产生zeta电位，并且在确定悬浮液的粘度方面具有重要意义。然而，另一个重要的表面特征——界面张力——似乎没有引起太多关注。本文介绍了一项这样的初步研究的结果，在该研究中，固体表面的接触角通过涂上防水硅+一种油而发生变化，并注意到相应的表观粘度变化。对其他一些参数也进行了研究。
The viscosity of a suspension is influenced by several factors which include shape, size, size distribution, concentration, density and surface characteristics of the solids and viscosity of the suspending medium. Effects of particle concentration"'2'~ hape'~'~', ize'~*''size distribution and shear rate (') on the viscosity of suspensions have been reported. Surface charge gives rise to zeta potential in a suitable environment and has been to be of great consequence in determining the viscosity of suspensions. However, another important surface characteristic-interfacial tension-does not seem to have attracted much attention. This note presents the results of one such preliminary study" o'where the contact angle of the solid surfitce was varied by coating it with a water repellent silic+ one oil and the corresponding change in apparent viscosity was noted. Some of the other parameters were also studied.
