摘要: 以桉木热磨机械浆(TMP浆)为研究对象, 探讨了非硅过氧化氢漂白稳定剂G1、G56替代硅酸钠用于桉木TMP浆漂白的可行性, 并对漂白工艺条件进行了优化。结果表明:桉木TMP浆过氧化氢漂白采用稳定剂G1、G56替代硅酸钠是可行的。在浆浓(质量分数)20%、H2O2用量9.0%(以绝干浆质量计,下同)条件下优化的漂白工艺条件为:G1用量0.5%, G56用量0.5%, NaOH用量5.85%, 温度90 ℃和时间30 min。在此工艺条件下桉木TMP浆单段过氧化氢漂白后, 浆的白度达到77.47% (ISO), 比原浆白度高38.89个百分点, 比2%硅酸钠用量下漂后浆的白度高1.75个百分点, 与2%硅酸钠和2%DTPA同时用作稳定剂的白度(79.88%(ISO))相当。

Abstract: The feasibility of non-silicon stabilizer G1 and G56 applied in hydrogen peroxide bleaching TMP pulp of Eucalyptus was investigated and the bleaching conditions were optimized.The results showed that the substitution of sodium silicate with G1 and G56 as the stabilizer in hydrogen peroxide bleaching for TMP pulp was technically feasible.Under the conditions of mass fraction of pulp 20 %,H2O2 9.0 %,temperature 90 ℃,time 30 min,the optimal bleaching chemicals charge were G1 0.5 %,G56 0.5 %,and NaOH 5.85 %.After single hydrogen peroxide bleaching stage,the brightness of bleached TMP pulp could increase more than 38.89 %ISO compared with the unbleached pulp and more than 1.75 %ISO compared with 2 % of sodium silicate.This brightness was similar to that by 2 % sodium silicate and 2 % DTPA (79.88 % ISO).
