摘要
对落叶松的多硫化钠法(简称PS)与硫酸盐法(简称KP)纸浆得率进行比较,发现在本实验的条件下,特别是正交实验时,多硫化钠法的纸浆得率有效显著的提高。另外,残碱中硫化钠浓度分析说明,多硫化钠法和硫酸盐法有截然不同的变化规律。
The research has been done on the pulp yield increase of PS cooking compared to KP cooking with larch. Besides, the analysis of sulfide concentration in black liquor indicated that PS cooking is very different from that of KP cooking.
