Hubbe, Auteur ; Soheila Izadyar, Auteur Année de publication : 2008 Article en page(s) : p. 4302–4307 Note générale : Bibliogr. p. 4307 Langues : Anglais (eng) Mots-clés : Poly-aluminum  chloride-rosin;  Sizing  variables Résumé : The effects of process variables, including poly-aluminum chloride (PAC) and rosin levels and equilibration time on PAC−rosin sizing performance, were investigated for three alternative sizing processes, include conventional, reverse sizing, and premixing under neutral papermaking conditions. The individual and interaction effects of sizing variables were determined. It was found that, in contrast to conventional sizing, the sizing efficiency increased with increasing equilibration time when reverse and premixing processes were used for the sizing treatment. In both processes, increasing equilibration time can lead to potential savings in PAC or rosin. Finally, the optimum conditions for more cost-effective sizing were determined for the three sizing processes.
