Abstract

Paper recycling is one of the valuable conventional processes in the worlds. But in this process, some of recycled paper faces reduction in some of mechanical properties. Using different additives such as lignocellulosic nanofibers (LCNF) is one of the main solutions for improving these mechanical properties. In contrast with some other additives, the special physical and chemical structure of LCNF seems to be effective in its distribution in pulp suspension and also its performance. For this purpose, in this study, two mixing methods, conventional mixing (with mechanical stirrer) and intense mixing (with disintegrator) were considered. The results showed that increasing the mixing intensity of this mixture caused better dispersion of LCNF and the tensile index increased from 21 N.m/g in conventional mixing to 30 N.m/g in intensive mixing. In addition, considering the decreasing effect of LCNF application in pulp on its drainability, so after determination of proper mixing method, the effect of applying bentonite-chitosan microparticle system on its drainage was considered. The results indicated that this system could improve the drainage from 132 ml CSF in treatment containing only LCNF to 189 ml CSF in the treatment containing LCNF/ microparticle system with no effect on mechanical properties of final paper or even improving them.
