Water Soluble Polymer Flocculants: Synthesis, Characterization,

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

flocculation of pcc filler in papermaking: influence of the particle

Flocculation of PCC filler in papermaking: Influence of the particle

Flocculation was carried out in the presence of a high molecular weight CPAM (cationic polyacrylamide) with very high charge density. The light diffraction scattering (LDS) technique was used to monitor flocculation, deflocculation and reflocculation by measuring the flocs size distribution with flocculation time ( ISO 13320-1, 1999 , Rasteiro et al., 2008 ).

Cationic cellulosic derivatives as flocculants in papermaking

The flocculant with the highest degree of polymerization and charge originated the best results, particularly when the filler used was kaolin, proving that water-soluble cationic cellulose derivatives can aid in the flocculation of fillers used in papermaking. On the contrary, the shortest-chained derivative was not effective.

Effect of Shearing Forces and Flocculant Overdose on Filler

The flocculation by cationic polyacrylamide (CPAM) or poly (aluminum chloride) (PAC) was determined using a focused beam reflectance probe. The effect of shear forces on aggregation kinetics depends on particle size. PAC produces soft flocs.
