Abstract

Recently, using chitosan-nanosilica system in papermaking has been considered in several investigations. In the present research, confirming the performance of this nanoparticle system in producing paperboard from recycled old corrugated container pulp, the electrostatic performance of chitosan polyelectrolyte in process and product properties was investigated. In this respect, pH of pulp suspension, as one of the main factors affecting the chitosan electrostatic charge, was considered. The pH adjustment (5, 7 and 9) was done by hydrogen chloride and sodium hydroxide. The results indicated that the process properties (drainage and first pass retention) have been experienced better situation affected by chitosan electrostatic charge in neutral and alkaline conditions. It seems that by changing the pulp suspension pH to neutral and alkaline conditions, the chitosan positive electrostatic charge and its solubility decreases and in contrast, the fiber's negative charge increases. This condition probably affected the chitosan polymer attachment and adsorption status on fibers surface (loop and tail position) in a way that they performed more effectively in floc formation. Therefore, drainage and retention increased about 37. 5 and 36. 5%, respectively, compared with the control sample and 34 and 7%, respectively, in comparison with the acidic condition. Although the mentioned system was successful in increasing the mechanical strength compared with the control samples, but the electrostatic charge changes in different pH conditions had less positive impact on these properties (except internal bonding strength).
