Chlorine Dioxide Bleaching of Sulfite Bagasse Pulp

LI Guo-ding

Abstract

The main factors affecting ClO2 bleaching of sulfite bagasse pulp were studied in this paper,orthogonal analysis was also being analyzed.The 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.
