摘    要:研究了在氨水中添加少量钾碱作为蒸煮剂的稳麦草制浆新工艺,讨论了蒸煮剂的用量和配比,液固比,蒸煮最高温度,升温时间和保温时间对蒸煮效果的影响,继而确定了适宜的工艺条件,结果表明,该蒸煮体系对稻,麦草木素的脱除率达到85%。纸浆得率为稻草38.12%(细浆得率)和麦草49.65%(粗浆得率)。通过红外光谱(IR)测定了稻草蒸煮过程中木质素的结构变化。

关 键 词:稻麦草  氨法制浆  木素  农用资源化  蒸煮剂  升温时间  保温时间  制浆工艺

Abstract:An advanced pulping technology which use aqueous ammonia added a little potash as cooking liquor on rice straw and wheat straw was studie d in the paper.The effects of the composition of cooking liquor,liquor to soli d ratio,the maximum temperature of cooking, time to maximum temperature and time at maximum temperature on cooking were discusse d systematically by experiment, and the optimum technological conditions were de termined. The results indicate that the rate of delignification of two raw mater ials were approximately 85%. The screen yield of rice straw was 38.12% and unscr e ened of wheat straw was 49.65% in the pulping process. The structural changes of lignin were detected by IR. Advantages of NH 4OH KOH pulping were discussed a nd utilization prospect of ammoniacal black liquor for agricultural resources wa s forecasted.
Keywords:rice and wheat straw  ammoniated pulping  lignin  agricultur al resources
