摘　　要：研究亚硫酸盐蔗渣浆二氧化氯漂白的主要影响因素,并对其进行正交分析。结果表明:二氧化氯漂白较适的条件为:二氧化氯用量2.4%,漂白时间30～60min,漂白温度50～60℃,浆浓6%～14%,pH2或4;漂后浆卡伯值5.15,白度55.9%ISO。继续采用过氧化氢漂白较易实现80%ISO以上的浆白度。The main factors affecting C102 bleaching of sulfite bagasse pulp were studied in this paper, orthogonal analysis was also being analyzed.T he results showed that the optimized bleaching conditions were ClO2 dosage at 2.4% and pH number at 2-4 with pulp consistency of 6%-14% at temperature of 50-60℃ for 30-60min. The pulp with kappa number of 5.15 and the brightness of 55.9%ISO after ClO2 bleaching can easily reach high brightness over 80%ISO using H2O2 bleaching.
