摘　　要： 本文研究了挤压疏解、化学预处理、H2O2和NaOH用量等对粉单竹CTMP H2O2漂白的影响。结果表明,挤压疏解可以改善原料对药品的吸收,减少抽出物等杂质对H2O2漂白的影响,提高粉单竹CTMP的可漂性;合理地控制碱比可以提高H2O2的漂白效果,过多的NaOH用量会使浆料发生“碱促黑”,降低浆料白度。 Effect of squeezing extrusion , chemical pretreatment, the charge of H2O2 and NaOH on H2O2 bleaching of white powdery bamboo CTMP were studied in this paper. It was showed that squeezing extrusion could improve absorption of raw material for chemicals and reduce effect of extractive on H2O2 bleaching, of white powdery bamboo CTMP. The effect of H2O2 bleaching could be improved through tio. Too high dosage of alkali would decrease the brightness of pulp. so improve bleachability control H2O2 to alkali ratio. Too high dosage of alkali would decrease the brightness of pulp.
