对残余木素含量不同的浆料的碱抽提(E)段条件进行了分析,测定了O2和H2O2的添加效果,分析E段中替代NaOH和提高浆料白度的可能性。NaOH用量和采用更剧烈的条件取决于进浆的卡伯值。
The condition of alkali extraction (E) of pulp with different residual lignin content was analyzed. The effect of adding O2 and H2O2 was determined. The possibility of substituting NaOH and improving the whiteness of pulp was analyzed. NaOH dosage and the use of more severe conditions depends on the kcal into the pulp.
