摘要
该文研究了表面活性剂与分散蒽醌（AQ）复配，作为尾巨桉碱性亚钠制浆的蒸煮助剂的应用效果。实验表明：分散AQ用量0．06％，表面活性剂SA用量0．15％，二者复配后在蒸煮过程中作用效果最佳；与桉木AS-AQ（晶体AQ）相比，在相同卡伯值下制浆得率可以提高2％-3％，同时浆料中有机溶剂抽出物下降。
The performance of surfactant used together with dispersible AQ as a cooking additive in E. urophylla grandis, UG cooking was investigated. The results show that when the dosages of the surfactant and dispersible AQ are 0.06% and 0.15% respectively, the two show best synergistic effect on the cooking. The yield can be increased by 2% - 3% compared with that of AS-crystal AQ pulping at the same kappa number, while the organic solvent extracts in pulp are decreased.
