摘要/Abstract

摘要： 为优化烟梗氧碱制浆工艺条件，在单因素试验基础上，通过Box-behnken响应面分析优化碱用量、保温温度和保温时间对细浆得率的影响。结果表明：碱用量及碱用量和温度之间的交互作用对烟梗细浆得率影响极显著，在较优的工艺条件（碱用量15.5%、保温温度75℃、保温时间45 min）下细浆得率为29.35%，与预测值29.48%接近。通过分析对比烟梗机械浆与烟梗氧碱浆纤维的显微结构发现，烟梗经过氧碱制浆后，纤维的分丝帚化程度较好，纤维表面也比较光滑，纤维既细且长，两端尖削，且烟梗中非纤维细胞较多。

Abstract: The alkali-oxygen pulping for tobacco stem were optimized in present study. Based on the results of single factor screening experiments, the impacts of alkali dosage, pulping temperature and holding time on screened pulp yield were analyzed by using the Box-Behnken experimental design and the response surface methodology. The results showed that the pulp yield was significantly affected by the alkali dosage and cooking temperature. The optimum pulping was realized as the tobacco stem was treated by 15.5% alkali dosage (on basis of tobacco stem mass) at 75℃ for 45 min. The screened pulp yield of tobacco stem alkali-oxygen pulping was 29.35% under these conditions, which was closed to the predictive value. By contrasting the microscopic structure of fibers of alkali-oxygen tobacco stem pulp and mechanical one, it was found that the former was well fibrillated, smoother, thinner and longer fibers with tapered ends were observed. In addition, much more non-fibrous cells were involved in the cooked tobacco stem pulp.

Key words: tobacco stem, alkali-oxygen pulping, fiber, response surface analysis
