4) selectivity of delignification
脱木素选择性
1.

针对过氧乙酸脱木素选择性进行了研究:由二氧化氯、次氯酸盐和过氧乙酸漂白浆的卡伯值降低程度、黏度以及脱木素选择性综合分析可得,过氧乙酸漂白脱木素选择性略优于二氧化氯,明显优于次氯酸盐。
2.
The results show that after the pretreatment of sodium sulfide solution, the speed of delignification was much greater than conventional kraft pulping, and the selectivity of delignification was improved.
大叶相思树木片用硫化钠溶液预处理后进行硫酸盐法蒸煮的结果表明,用硫化钠溶液预处理后,脱木素速率较常规硫酸盐法蒸煮快得多,脱木素选择性也明显提高,浆料卡伯值较低时(低于145),硫化钠预处理硫酸盐法蒸煮浆料得率较常规硫酸盐法蒸煮高。
5) delignification selectivity
脱木质素选择性
1.
Then ozonic-hydrogen peroxide bleaching were carried out and the results show that the higher of Kappa number, the poor of the delignification selectivity and the lower of brightness rising.
