Ozone bleaching and nano‐filler loading for enhanced reed fiber papermaking

ملخص البحث

It is aimed in this work to explore the possibility of using the reed stalks for the production of pulp suitable for papermaking. To attain this goal, chemical kraft pulping followed by a number of bleaching sequences was implemented. We bleached a reed kraft pulp using H1H2, D0EOD1 and ZEOD sequences (where H, D, EO and Z represent hypochlorite, chlorine-dioxide, alkaline extraction, and ozone respectively) to attain considerably good quality pulp that boosts the brightness and brings high mechanical strength. The elementary chlorine-free (ECF) light bleaching sequences (ZEOD) include an ozone stage which results in imparting a pulp quality to be better than the conventional ECF procedure (D0EOD1) and (H1H2). Furthermore, to determine the optical, physical, and mechanical properties of reed pulp and paper, the impact of filler retention regarding the properties of paper that incorporates fibers from nano-filler (CaCO3) loading was investigated and compared with the conventional filler loading. The same amount of nano calcium carbonate additive helps impart optical and mechanical properties compared against the paper manufactured by conventional calcium carbonate.
