ELECTROKINETICS.

Abstract

There has been a great deal of information published regarding the relationship between electrokinetic properties of a paper system and the interaction of components in a paper stock, the properties of the forming sheet, and the properties of the finished sheet. Most of this information is empirical, often indicating that approaching zero point of charge is the desired point for maximum effect, but at times other responses are indicated. Empiricism can be extremely useful and necessary, but conceptual understanding must be sought in order to broaden application and to identify empirical directions. The purpose of this chapter is to outline the conceptual foundations of the electrokinetic phenomena, to discuss the instruments used to measure the electrokinetic properties of paper systems, and to comment on the validity of electrokinetic measurements. Details of the measuring system are given.
