Effect of eucalypt pulp extractives on the retention performance of polyethylene oxide and phenolformaldehyde resin






Appita Journal 45(3): 189-192

Effect of eucalypt pulp extractives on the retention performance of polyethylene oxide and phenolformaldehyde resin

Variations in the polyphenolic content pH and ionic strength of pulp have been found to affect the retention performance of the dual retention aid system of polyethylene oxide (PEO) and phenolformaldehyde resin (PFR). Polyphenolics from unbleached eucalypt pulp interfere with the mechanism by which the polymers improve fibre retention.
