摘要
研究了不同黑液预处理条件对硫酸盐蒸煮黑液预处理桦木 ,硫酸盐蒸煮的影响。结果表明 ,经过适当的工艺处理后 ,脱木素的选择性较常规硫酸盐蒸煮有显著作用 ;所得的浆卡伯值低 ,而其粘度损失较小。
The influence of different black liquor pretreatment conditions on the birch kraft pulping was studied. The results show that delignification selectivity of pulping can be improved,the pulp with lower kappa number but less viscosity loss can be produced by using rational technology and condition of black liquor pretreatment.
