摘要
本文研究了聚氧化乙烯(PEO)和改性酚醛树脂所组成的双元助留助滤系统在新闻纸中应用工艺。研究表明,体系pH值为5.0左右时,聚氧化乙烯(PEO)用量O.06％-0.08％,改性酚醛树脂用量为1.0％时,助留助滤效果最好,并且对纸张裂断长的提高有一定好处。
The applied processes that PEO/(polyethylene oxide)/modified phenolic resins usnig in newsprint as retention and drainage aid were studied in this paper. The best effect of retention and drainage was achieved when pH5.0,PEO and modified phenolic resins dosage was 0.06%-0.08% and 1.0% respectively.
