Experimental Study on Electrokinetic of Kaolinite Particles in Aqueous Suspensions
Influence of aqueous phase properties and process parameters on kaolinite particle zeta potential was quantified by electrophoresis experiments. The results indicated that pH strongly altered the zeta potential of kaolinite and it decreases at the beginning and then increases in the range of pH = 2–13. The activity of different cations changes the zeta potential and has the following tendency o...
متن کاملPreparation of Stable Suspensions of Delaminated Kaolinite by Combined Dimethylsulfoxide-ammonium Fluoride Treatment
The separation of kaolinite crystallites into their layer components involves two problems, namely, overcoming the bonding energy which holds these layers together, and imparting the latter with a new surface potential that prevents their reunion, once they are separated. To chemical this author's knowledge, the separation of kaolinite into its lamellae to form a stable suspension has never bee...
متن کاملThe Effect of Electrolyte Concentration and Ph on the Flocculation and Rheological Behaviour of Kaolinite Suspensions
The effects of the electrolyte concentration and pH on the settling behaviour, floc sizes and rheological behaviour of kaolinite suspensions were investigated. The results show that the settling behaviour of kaolinite changes with the ionic strength and pH of the suspension. In the acidic pH range, (pH 2) particles settle in flocculated form regardless of electrolyte concentration, however, in ...
متن کاملInstability regimes in flowing suspensions of swimming micro-organisms
The effects of an external shear flow on the dynamics and pattern formation in a dilute suspension of swimming micro-organisms are investigated using a linear stability analysis and three-dimensional numerical simulations, based on the kinetic model previously developed by D. Saintillan and M. J. Shelley, Phys. Fluids 20, 123304 2008 . The external shear flow is found to damp the instabilities ...
متن کاملModeling product variations in hard disk drive micro-actuator suspensions
The increase in aerial storage capacities of future magnetic hard disk drives has fostered the use of dual-stage actuators for high track density data recording. In a hard disk drive with a dual-stage actuator the standard rotary actuation of the voice coil motor is combined with an additional micro or milli actuation to accomplish high-bandwidth and highly accurate track following. In order to...
