摘要
本文对马尾松磨木浆(SGW)进行了单段H2O2漂白和两段H2O2漂白试验,确定了H2O2漂白的最佳工艺参数。当采用两段H2O2漂白时,纸浆白度可由原浆的47.8%提高到74.5%,从而使制得的漂白浆能满足低定量高白度胶印新闻纸和其它高级纸种的生产要求。
The one stage and two stages H2O2 bleaching of SGW from Masson Pine were investigated in this paper. Several parameters in H2O2 bleaching process were studied systematically.The results showed that a brightness of 74.5% (SBD) can be achieved by two stages H2O2 bleaching after pretreatment under the optimum conditions.
