Pulping properties of bleached chemimechanical pulps from poplar-wood processing residues and properties of Munken paper made from this pulp as blend were investigated.Results show that the optimized conditions were as follows: the dosages of H2O2 5.0 % and NaOH 4.5 %.Under these conditions the brightness level of the bleached chemimechanical pulps was 78 %(ISO).At the freeness level of 100 mL(CSF),pulps bulkiness and tensile strength of the pulp could reach 2.1 cm3/g and 38 N·m/g,respectively… CONTINUE READING
