Using the SZP-04 or SZP-06 electrodes to reverse the charge of a kaolin slurry by adding polyvinylamine.
Method Determination of Zeta Potential
Sample Highly anionic dispersion of kaolin
Solid content approx. 28%
Sample preparation A 10% solution (referring to commercial base) of the polyvinylamine is prepared by dilution with tap water. This solution is added stepwise to 100 ml of the kaolin slurry. Stir the mixture properly before determining the zeta potential.
Equipment SZP-04 or SZP-06, special electrodes for pigment slurries, filter circle (white ribbon)
