| 摘 要： | 白水封闭循环会引起阴离子干扰物及无机盐积累,使湿部环境恶化,导致助留助滤体系效能降低。实验比较了三种助留助滤体系在白水内部循环情况下的助留助滤性能及一些湿部参数的变化情况,结果表明：白水多次循环使用后,造纸湿部化学环境恶化,纸料的留着及滤水性能快速下降。相比较之下,采用MPAM与ACS组成的絮聚体系由于兼有捕集阴离子垃圾和软化硬水的功能,阳电荷需求量下降明显,并且能保持相对稳定的助留助滤效果。

| Abstract: | Closed circulation of white water will cause anionic dis-turbance and salt accumulation,it can make the environment of wet-end worse,and will make the retention and drainage aid sys-tem lose effectiveness.Three kinds of retention and drainage aid systems were compared in this paper for the retention and drain-age effects and some parameter variation in wet-end environment.The applying results show that after the imitation of white water recycle,the retention and drainage effects of pulp declines because of ... |
