摘　　要：为了提高化学浆得率,提出黑液循环蒸煮木片制浆方法。通过基础实验和工业生产试验研究,得到结果:黑液循环制备化学浆的基础实验用碱量为木片的26%,浆得率为63.6%,比传统碱法制浆工艺得率50.0%提高13.6%;在工业生产试验中,用碱量为木片的18%,结合蒸煮压力波动变化,纸浆平均得率为63.9%,比传统蒸煮制浆工艺得率50%提高13.9%。此外,循环蒸煮获得的纸浆性能良好,从而证明黑液循环蒸煮木片的制浆方法是可行的。In order to improve the chemical pulp yield,a pulping method of black liquor circular cooking was proposed.The results showed that the amount of alkali used in the basic experiment of black liquor circular cooking is 26%of that of traditional pulping,and the pulp yield is 63.6%,13.6%higher than the traditional alkali pulping process.In the industrial production test,the amount of alkali used was 18%of the traditional pulping method,and the average pulp yield was 63.9%,13.9%higher than the traditional pulping process.In addition,the pulp obtained by the circulating cooking method has good performance,proving that the pulping method of black liquor circular cooking is feasible.
