双元助剂强化慈竹蒸煮

Reinforcement of Neosinocalamus Cooking Using Dual Cooking Aids

研究双元蒸煮助剂在慈竹硫酸盐蒸煮过程中的应用。结果表明,添加改性蒽醌对蒸煮的强化脱木素作用效果明显。巴克曼蒸煮渗透剂 A、B、C 分别单独使用时不仅没有强化脱木素作用,而且会使黑液残碱降低、纸浆得率下降。巴克曼蒸煮渗透剂 A、B、C 与改性 AQ 双元复配使用时均可提高蒸煮效果,使得成浆卡伯值下降、细浆得率提高。其中巴克曼蒸煮渗透剂 A 与改性 AQ 双元复配使用时效果最好。改性 AQ 与巴克曼蒸煮渗透剂 A 双元复配使用时:当改性 AQ 用量 0.05%,巴克曼蒸煮渗透剂 A 用量 0.03%,成浆得率提高 1.31%,卡伯值下降 4.0;当改性AQ 用量 0.06%,巴克曼蒸煮渗透剂 A 用量 0.03%,成浆卡伯值降低了 6.4,细浆得率基本不变。

It was studied that dual cooking aids on bamboo pulping. Modified AQand infiltration aids were used to improve the cooking technology. The results showed that modified AQ_could strengthen the cooking, but infiltration aids couldn＇t reach the good expect in cooking. When the modified AQand infiltration aids were used together in cooking, it could obviously decrease the kappa number of the pulp and enhance the yield of pulp. Infiltration aids Busperse 2806 was the best choose to use in cooking with modified AQ,. When the dosage of modified AQ 0.05%, Infiltration aids 0.03%, the yield of pulps increased 1.31%, kappa number decreased 4.0, and the dosage of modified A0..0.06%, Infiltration aids 0.03%, kappa number decreased 6.4 and the yield was the same level.
