摘要 介绍了荧光增白剂(OBA)在高得率浆H2O2漂白中的两种应用方式,即"漂中加入OBA"和"漂后加入OBA";探讨高得率浆的"H2O2/OBA"漂白工艺与传统H2O2漂白工艺的优缺点。结果表明,与高得率浆传统的H2O2"化学漂白"相比,这种"H2O2/OBA"的"化学/物理"漂(增)白相结合的方式更能保持高得率浆的特性;"漂中加入OBA"的方式要优于"漂后加入OBA"的方式。 In this study, two application modes of optical brightening agent （OBA） in peroxide bleaching of HYP, OBA was applied with bleach liquor and OBA was applied after bleaching, were compared. Also, the advantages and disadvantages of peroxide/OBA bleaching and traditional peroxide bleaching were investigated. The results showed that, compared with conventional peroxide bleaching process, the unique properties of HYP could be maintained by both application modes of peroxide/OBA bleaching efficiently. Moreover, the application mode of adding OBA with bleach liquor was better than the counterpart （ adding OBA after bleaching）.
