Thread Forming Property of Slurries and Aggregated Structure of Nanoparticles

Abstract

Aggregate structure of fine particles and thread forming property of thick slurry was investigated. Slurries could be classified into three states of aggregate structure depending on the dispersant concentration. The rheological behavior of slurries was determined by the aggregate structure of fine particles. The relationship between the dispersion state of particles and the surface tension were measured by a drop weight method. As a result, the thread forming property of thick slurry is reflected on the surface tension and apparent viscosity, and therefore measurement of surface tension and apparent viscosity may give the information on particle dispersion state.
