摘要
结合工厂生产实际研究了脱墨浆生产中甲脒亚磺酸 (FAS)漂白的影响因素及其漂白时的注意事项 ,并探讨了漂白后酸化的重要性及其酸化所带来的影响。研究结果表明 ,FAS的合适用量为0 4%～ 0 5 % ,FAS与NaOH加入比例为 1∶1 ;在生产上 ,时间对FAS漂白的影响不是很大 ;漂白后进行酸化是有必要的 ,但会带来白度的降低 ,而化机浆则出现相反的情况。
In this article, the factors affecting formamidine sulfinic acid (FAS) bleaching of DIP were studied; the importance and necessity of acidifying after bleaching and the effect of acidifying on DIP were also discussed. The results showed that brightness of DIP increases with the amount of FAS when its dosage is in between 0.25%～0.5%, the optimum dosage of FAS is 0.4%～0.5%, the optimum ratio of FAS and NaOH is 1:1, bleaching time has no significant effect on the resultant pulp. Acidifying after bleaching is necessary but can result in the brightness decrease of the pulp, however it is not the case for APMP.
