Slurry viscosity testing
WebbMeasuring the viscosity of pastes, slurries, gels and suspensions can be a real challenge without the right equipment. The non-Newtonian behaviour of these materials presents a number of challenges to a simple viscometer: Multiple viscosity readings must be taken at different shear rates to characterise degree of non-Newtonian behaviour. Webb16 sep. 2024 · The slurries produced by the two dispersion methods were then characterized by their low and high-shear viscosities, particle size distribution, surface area, and their composition. Table I shows the results of the viscosity measurements for the different high-viscosity clay samples dispersed using the two different dispersion …
