New information on the role of cofactor in PEO-type retention aid systems
Abstract
The flocculation of three colloidal dispersions (precipitated calcium carbonate (PCC), TiO2 and a calcined clay) using a combination of polymeric flocculants and cofactors was investigated. The flocculants used were PEO (MW = 9×106). CPAM (a cationic copolymer of acrylamide) and POLYPAM-CO-PEG (a non-ionic comb copolymer (MW = 5×106) consisting of a polyacrylamide backbone with ∼ 1mole % pendent PEG chains). The cofactors were based on …
