麦草化机浆制浆及漂白的研究

Wheat Straw CMP Pulping Technology and Bleaching with CH3COOOH and H2O2

对麦草化机浆生产过程中预处理时的主要影响因素用碱量、温度、时间进行了研究,并对过氧乙酸与过氧化氢组合漂白的效果进行了分析。结果显示,预处理段较优的条件为:用碱量6%,温度110℃,保温时间60 min。组合漂白效果显著,Pa置于首段时漂白效果较好。

The main pretrcatmental parameters of wheat straw CMP including the charge of NaOH, temperature, and time as well as the bleaching of the pulp with CH3 COOOH and H2O2 combination were investigated in this paper. The results showed that the suitable pretreatment conditions are as follows： the charge of NaOH is 6% , temperature is 110℃, time is 60 min. And the effect of the combination bleaching is good, particularly when CH3 COOOH is used for the first stage.
