Stabilization of a Concentrated Suspension of Calcium Carbonate with Cationic Praestol

摘要

The sedimentation stability of a 60 suspension of calcium carbonate in the presence of various commercial samples of cationic Praestol was studied, using a torsion balance, in relation to the concentration and molecular weight of the polymer, concentrations of NaCl and CaCl_2, and particle size of calcium carbonate.
