Abstract

Production of test liner and fluting paper from OLD CORRUGATED CONTAINERs is one of the most common paper recycling processes in Iran. This type of papers are among the high basis weight papers and also contain significant fine fibrous and non-fibrous materials. Hence, the drainage and in addition, the retention of fine materials, are the obstacles for the paper mills. In these cases, usually application of drainage/retention aids, such as nanoparticle systems can be of good help. In this respect, colloidal silica and bentonite are the two most commonly used nanoparticles with polyelectrolytes in papermaking wet-end. Therefore, in this research, the effect of bentonite and silica sol nano-particles on the performance of CATIONIC STARCH was compared in terms of DRAINABILITY, retention and strength properties of paperboard from recycled OLD CORRUGATED CONTAINERs.The analysis of the particle size for these two nanoparticles showed that although the thickness of bentonite platelets (maximum 22 nm) was less than NANOSILICA dimensions (less than 50 nm), the effect of bentonite-cationic starch was not significant in terms of retention, against the NANOSILICA. Regarding the DRAINABILITY, following dosing of both silica and bentonite, the parameter much improved (up to 186% in the case of NANOSILICA). On the other hand, application of CATIONIC STARCH containing systems in paper hand sheets resulted in the improvement of tensile and tear indices. However, these properties decreased following addition of nano-particles. Also, internal bonding (Scott- type) incredibly increased (up to 354%) by application of CATIONIC STARCH and NANOSILICA. Finally, generally in the case of OCC furnish, the NANOSILICA-cationic starch system had a better performance in terms of DRAINABILITY, retention of fine materials and fiber fines and also strength properties, rather than CATIONIC STARCH-bentonite.
