摘　　要：对桉木磺化化机浆ＣＨ３ＣＯＯＯＨ、Ｈ２Ｏ２漂白的主要影响因素：药品用量、温度、时间、ｐＨ值、浆浓进行了研究，并对ＣＨ３ＣＯＯＯＨ、Ｈ２Ｏ２组合漂白程序进行了优化选择，得出了较佳工艺条件及较佳的组合程序Ｐａ－Ｐ及Ｐ－Ｐａ－Ｐ，同时对漂白前后纸浆红外光谱的变化进行了分析，初步探索了反应机理。The main bleaching parameters including the charge of peracetic acid,temperature,time and pH etc.in the bleaching process of eucalyptus SCMP were investigated in this paper.The different bleaching sequences were studied and the results showed that Pa P,P Pa P are the optimal bleaching sequences.
