对漂白对全棉秆漂白化学浆尘埃度的影响进行了研究。结果表明,全棉秆漂白浆的尘埃主要来源于棉秆皮的黑色尘埃。由NaOH-AQ浆经氯化-碱抽提后的补充漂白可以看出,在白度相近的情况下,过氧化氢去除尘埃的能力稍优于次氯酸盐和二氧化氯,但3种漂剂去除尘埃的能力差别较小;漂白流程采用漂剂为氯气较氧气有较好的除尘埃效果。 The bleaching of cotton stalk bleaching chemical pulp dust degree was studied. The results showed that the dust of bleached pulp of cotton stalk mainly came from the black dust of cotton stalk bark. From the bleaching of NaOH-AQ pulp after chlorination-alkali extraction, it can be seen that the ability of hydrogen peroxide to remove dust is slightly better than that of hypochlorite and chlorine dioxide in the case of similar whiteness, but three Bleaching agent to remove the difference between the ability of dust smaller; bleaching process using bleaching agent for chlorine gas is better than oxygen dust effect.
