The electrokinetic influence of an anti-linting Fisher-Tropsch wax emulsion on Newsprint

Madelyn Bekker, Nicolaas Roussouw Louw and Glenda Vanessa Webber .

Zeta potential is the parameter that determines the electrical interaction between particles, a high value, positive or negative, prevents flocculation. When a chemical additive (such as a cationic emulsion) is absorbed on the particle surface the size of the double layer is compressed. This will manifest in a lower (negative or positive) zeta potential. Zeta potential is a sensitive measure to determine the amount of an additive absorbed on the fibre surface. The objectives of this work were to investigate electrokinetic influences in papermaking and to measure the electrokinetic influence (zeta potential, electrophoretic mobility and cationic demand) on fibres and fine particles of a cationic Fischer-Tropsch wax emulsion added to newsprint pulp for anti-linting purposes.
