碱法麦草浆漂段间配合及优化的研究

The Complementation of Bleaching Agents and Optimization of Bleaching Conditions of Wheat Straw Soda_AQ Pulp

用单段最佳条件分析中，麦草烧碱ＡＱ浆在氧脱木素条件以用碱量为３％时，后续Ｈ２Ｏ２漂白时，Ｈ２Ｏ２用量２．５％，纸浆的白度可达到６５％（ＩＳＯ）以上，而作为整体探讨时发现，在氧脱木素条件以用碱量为２．５％时，后续Ｈ２Ｏ２漂白时，Ｈ２Ｏ２用量为２．５％，纸浆的白度可达到６６％（ＩＳＯ）以上。

We used a new method to analyse the optimal conditions in wheat straw Soda_AQ pulp bleaching.From the seperated stage analysis, the optimal condition of alkali charge is 3% in oxygen delignification and hydrogen peroxide is 2.5% in hydrogen peroxide bleaching stage,the brightness of the pulp could be above 65%(ISO). From the complemental stage analysis, the optimal condition of alkali usage is 2.5% in oxygen delignification and hydrogen peroxide is 2.5% in hydrogen peroxide bleaching stage. The brightness of the pulp could be above 66% (ISO).
