Kaolin Pigment - Latex Interactions During Coating, 1994 Coating Conference Proceedings
K. R. Hase, D. W. Bousfield
The motion of disk and spherically shaped particles in shear fields is modeled using a modified Stokesian dynamics technique. Disk shaped particles are used to represent delaminated kaolin pigments, and spherically shaped particles are used to represent latex or other pigments. Expressions found in the literature for hydrodynamic interactions between nonspherical particles are used. Colloidal forces are included in the model. The viscosity of the suspension is calculated by the model. The model is compared to experimental data for monosized glass plates, kaolin pigments, and a mixture of kaolin and latex.
