摘要
在D0 段采用高温 (95℃ )二氧化氯漂白 (总漂序为D0 EPD1)比在低温下二氧化氯流程 (D0 EPD1D2 )具有更高的漂白效率。对卡伯值 10 2的经氧脱木素后的硫酸盐阔叶木纸浆来说 ,在相同的终漂白度要求(88%ISO)时 ,前者可以节约 2 0
High temperature ClO 2 bleaching (D0EPD1) has higher bleaching efficiency than the low temperature conventional sequence For the oxygen delignified kraft pulps(kappa number 10 2),the former sequence saves more than 20% chlorine dioxide charge compared to the later one when reaching the same high brightness(88%ISO) Low pH value in D0 stage of high temperature bleaching will promote the delignification and hydrolysis processes HuA is thus removed in D0 stage,and the bleaching efficiency is improved in subsequent stages
