摘要:研究了漂白助剂在次氯酸盐漂白浆生产中的应用效果。结果表明，漂白助剂对竹浆、蔗渣浆与竹桉混合浆纤维都有较好的保护作用，能提高漂白浆的得率、黏度，在漂白助剂用量较低的情况下漂白浆的质量稳定，而且生产成本有一定程度的降低。

Abstract:Utilization of bleaching additives in production practice was studied, the results showed that, bleaching additives have good protection effect on the fibers of bamboo pulp, bagasse pulp or mixed pulp of bamboo and eucalyptus. And adding bleaching additives is helpful for the improvement of the yield of H stage, viscosity and whiteness of CEH bleaced pulp. The bleached pulp quality can be stable when small amount of bleaching additives are used in H stage.Furthermore, production cost can be reduced to certain degree.
