CONTRIBUTION OF HIGH TEMPERATURE IN CHLORINE DIOXIDE BLEACHING

摘要：

High temperature in D0-stage of chlorine dioxide bleaching is beneficial for saving chemical charge and improving fibers quality. This paper researched the influence of 90℃ instead of 65℃ in D0-stage on chlorine dioxide charge and fibers quality. The bleaching sequence of D0EopD1 was adopted to bleach oxygen delignified kraft eucalyptus pulp. To achieve the same brightness of 90％ ISO, the bleaching process with high temperature saved 11.7％ chlorine dioxide charge at laboratory scale, and the viscosity of pulp from high temperature bleaching process was increased 11.5％ compared with that from routine temperature bleaching process. Simultaneously the handsheets made by pulp from high temperature bleaching process showed better strength properties.
