彩色办公废纸脱墨浆的漂白与脱色

摘 要 针对彩色办公废纸脱墨浆的特点,选用了几种漂剂(H2O2、保险粉、FAS),研究了其漂白与脱色效果。结果表明,保险粉的脱色效果最好,FAS的漂白能力最佳。从漂白和脱色两方面分析,FAS是处理彩色办公废纸脱墨浆的首选药剂。在此基础上,对影响FAS漂白与脱色效果的诸多因素进行了研究,并优选出最佳适用条件。关键词 彩色办公废纸 脱墨浆 漂白 脱色 二氧化硫脲Bleaching and Decolorizing for Deinked Pulp of Colored Office WasteHou Yanzhao Sun Laihong He Zhibin Liu Yufeng(Pulp and Paper Industrial Research Institute of China,黄釉古玩Beijing,100020)ABSTRACT Bleaching and deco电子天平lorizing of deinked pulp of colored office waste by using several bleaching agents were investigated .The results showed that the decolorizing effect of sodium hydrosulfite was the best and th汽车行业是朗盛在高性能塑料产品方面最重要的客户e bleaching ability of FAS was the highest.
