Abstract

This work investigates the interaction of a common anionic polyacrylamide flocculant with a typical paper filler precipitated calcium carbonate over a range of suspension solids, polymer level, conductivity and calcium hardness. The approach involves monitoring the interaction by measurement of heat by solution microcalorimetry and particle chargeby electrophoretic and electroacoustic analysis. The study clearly shows the importance of polymer level and contact time control at low solids paper furnish conditions where the desired bridging interactions are generally at a disadvantage.
