Inhoud:
To use an automatic sedimentometer for suspension stability measurement, we compared the results given by this technique to other, more conventional, measurements of suspension properties: sediment volume, sedimentation rate, viscosity. The study was conducted with aqueous dispersions of synthetic calcium carbonate in the presence of sodium polyacrylate as a dispersing agent. Besides a very good correlation between all techniques, the combination of measurements gives an analysis of the polymer action process. There is first a step where bulky floes are disintegrated into dense aggregates, then the breaking up of aggregates into fine particles. The limit between both steps is sharply defined at a polymer concentration 830 mg/1.
