摘要
探讨了预处理和过氧化氢强化氧漂对氧脱木素的影响:结果表明:氧漂前用NO2预处理能显著提高氧脱木素的选择性和脱木素程度,而对漂后浆的白度影响较小,预处理后,添加0.5%~0.8%的H2O2,能大幅度提高氧漂后纸浆的白度,而纸浆的卡伯值和粘度相对下降较小。
The Effect of NO 2 pretreatment and H 2O 2 reinforcement on oxygen deliginification of Eucalyptus AS AQ pulping was invesigated.The results indicated that pretreatment with nitrogen dioxide(NO 2)would remarkably improve oxygen deliginificatiion selectivity and increase deliginification degree.A high brightness of the pulp could be achieved when the pulp was pretreated with nitrogen dioxide and further deliginified.
