Stability for dispersions : Determining the effects of PVP upon sedimentation of clay suspensions

For certain coatings applications, it is important to maintain the stability of fine particles in aqueous suspension. The theoretical effects of pH on the suspension stability of china clay in water were evaluated, and practical (centrifuge) tests were used to determine the effects of adding different molecular weights of the polymer polyvinylpyrrolidone (PVP) at constant pH....
