【摘要】 通过实验探讨了三倍体毛白杨低硬度NaOH-AQ浆(卡伯值13．5,粘度851 mL／g, 白度37％,ISO)H2O2强化氧脱木质素(QOP)的工艺条件,在此基础上提出了QOP、QP全无氯 漂白的漂序,此漂序可以把该纸浆漂至82．0％(ISO),粘度保持在716 mL／g,漂后纸浆得率 91．78％．而且该漂序可操作性强,是一种适合低硬度NaOH-AQ浆的全无氯漂白新工艺。更多还原

【Abstract】 Strengthened-oxygen total-chlorine-free(TCF) bleaching of NaOH-AQ pulp of low Kappa number from the triploid of Chinese white poplar(Populus tomentosa Carr.) with brightness 37 % (ISO),Kappa number 13.5,viscosity 851 mL/g was bleached with a TCF process-QOP,QP sequence in the laboratory.The bleached pulp with brightness 82.0%(ISO),viscosity 716 mL/g at bleached pulp yield 91.78% was obtained after QOP,QP bleaching.The data presented in the paper are useful for developing TCF bleaching sequence for the triploid of Chinese white poplar NaOH-AQ pulp of low Kappa number.更多还原
