Sažetak
This study investigated the effects of E-48 borax pentahydrate (A), E-67 agro boron (B), and Ground Colemanite (C) on properties of kraft pulp-paper obtained from European black pine and European aspen. The highest screened pulp yield values were determined by adding 8 % B during cooking of both species. The best pulp strength increases were determined by adding 8 % B during cooking of European aspen. Likewise, compared to control samples, the stability of Xylose, Mannose and 4-0-MeGlcA units was increased in European black pine kraft pulp after adding 8 % B. Furthermore, in producing the European aspen pulp, adding of 8 % A during cooking positively affected the total amount of hemicelluloses.
