Self-assembly of alkyl chains of fatty acids in papermaking systems: A review of related pitch issues, hydrophobic sizing, and pH effects Open
This review article considers the role of fatty acids and the mutual association of their long-chain (e.g.C18) alkyl and alkenyl groups in some important aspects of papermaking.In particular, published findings suggest that interactions in…

Optimisation of froth flotation for removal of wood extractives in paper manufacture Open
A laboratory scale froth flotation batch process has been optimised for removal of wood extractives from Pinus radiata thermo-mechanical pulp (TMP) process water. This has provided insight into the mechanism of flotation and has potential …

The effect of pH disturbances on the colloidal structure and fibre adsorption of Pinus radiata wood extractives Open
Experiments have been undertaken to investigate the effect of pH disturbances on the colloidal stability and phase distribution of Prudiala wood extractives. Adsorption experiments found that a perturbation of the pH resulted in increased …

Examination of variables influencing the selective froth flotation of wood extractives from Pinus radiata TMP process water Open
Effective separation of wood extractives from thermo-mechanical pulp (TMP) process water by froth flotation involves optimisation of many variables that influence the removal efficiency. To this end, the effects of surfactant concentration…
