摘　　要：以胡麻皮为原料,进行了Soda-AQ法制浆和AS-AQ法制浆研究。研究结果表明:在Soda-AQ法制浆中,用碱量以22%为宜,AQ的最佳用量为0.1%,最佳CT-1用量为0.5%;在Soda-AQ法分级蒸煮中,第一级使用2%的NaOH、第二级使用18%的NaOH的两级蒸煮效果最佳,纸浆卡伯值可达到13.3,纸浆得率为54.9%。在AS-AQ法制浆中,保温5小时的蒸煮中增加Na2SO3用量对蒸煮有利,而当保温为7小时时这种影响很小,AQ的合理用量为0.15%;在其它条件相同时,保温7小时的浆料比保温5小时的浆料卡伯值低2～4,保温7小时的蒸煮效果好于保温5小时。This paper has studied the pulping properties of Soda-AQ and AS-AQ pulping with LinumUsitatissmus Linn's bark as material. As a result, the optimum dosage of NaOH, AQ and CT-1 in Soda-AQpulping is respectively 22%, 0.1% and 0.5%. In AS-AQ pulping, the optimum dosage of AQ is 0.15%; withthe same pulping conditions, the kappa number of the pulp with 7 hours heat preservation is 2-4 units lowerthan the pupl with 5 hours heat preservation.
