Fluid Behaviors of Kaolin Slurry - AIChE

Kaolin slurry was prepared by mixing kaolin clay (Suzhou kaolin clay) and water. In slurry, pH was controlled by adding acid and base. There were different kinds of dispersants including anionic organic dispersants (e.g.PN), cationic organic dispersants (e.g. BO) and non-ionic organic dispersants (e.g. VD).The rheology was measured by Rotovisco ...

Maintaining Kaolin Storage Tanks - Thiele Kaolin

Treatment of Contaminated Kaolin Slurry Hydrogen peroxide is used to treat slurry spoilage. Begin with 100 ppm active peroxide per slurry ton of clay and agitate for four hours to allow the peroxide to dissipate. This equates to one gallon of peroxide per ten dry tons of clay. One application should be
