摘　　要：氧脱木素后的麦草浆,通过AP段不同时间和不同温度下处理,探讨纸浆的己烯糖醛酸、卡伯值、黏度、白度等指标确定最佳工艺条件,并且在最佳工艺条件下测定纸浆的金属离子、木素含量的变化情况。实验得出OP漂后麦草浆AP处理的最佳工艺条件为:pH3.0,温度90℃,保温时间180min,浆浓5%。Hydrogen peroxide enforced acid sequence treating wheat straw bleaching with oxygen delignification through different time and different temperature processing, Different bleaching variables were studied, especially determining the best condition including pulp hexenuronic acid, kappa number, viscosity, brightness and the metal ions, lignin content changes at the optimum conditions. Finally the experiments showed that optimum conditions of A P treatment of wheat straw after oxygen bleaching is the temperature is 90 ℃ , holding time of 180min, pulp consistency of 5% at pH 3.0.
