摘　　要：以杨木加工剩余物为原料，进行了漂白化学机械法制浆性能及配抄轻型纸的研究。研究结果表明：H2O2用量5．0％，NaOH用量4．5％，在此条件下制得的漂白化机浆白度可以达到78％（ISO）以上；加拿大游离度为100mL（CSF）时，纸浆的松厚度达到2．1cm^3／g以上，抗张强度达38N·m／g以上，以该条件制得的漂白化机浆配以10％。20％的漂白针叶木浆，抄造的轻型纸质量指标可以达到轻工行业标准（QB／T2809-2006）中轻型纸的质量指标要求。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 cm^3/g and 38 N-m/g, respectively. Munken paper products were manufactured by using this pulp blended with 10 %-20 % soft bleached kraft pulp. The quality of Munken paper could meet the requirements of the standard （ QB/T 2809 - 2006）.
