摘　　要：研究了麦草生物化机浆CH3COOOH漂白条件以及CH3COOOH与H2O2的组合漂白。结果表明:麦草生物化机浆过氧乙酸适宜漂白条件为:3%CH3COOOH、90min、50℃、pH5。经PaP3P3a和PaP5P5a漂白,麦草生物化机浆的白度分别可达61.9%和72.1%(ISO)。The bleaching of wheat straw bio-chemimechanical pulp CH3COOOH and the combining bleaching of CH3COOOH and H2O2 were investigated in the trials. The results show that the optimal conditions of peroxyacetic acid bleaching was 3% CH3COOOH, 50 C, 90 min, pH O 5. The pulp could be bleached to 61.9%ISO and 72.1%ISO brightness level respectively by using PaP3P3a and P5PaP5a, bleaching procedures.
