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。 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 Q Op, 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.
