| 摘要:本研究通过分级分离得到由纤维细胞（BF）和薄壁细胞（PC）组成的不同组织并分别进行碱法蒸煮，讨论了不同组织成浆过程的差异性。结果表明，在105~195 min内，卡伯值、黑液木质素浓度及木质素脱除率等存在显著差异。在最高蒸煮温度160 ℃时，维管束组织和薄壁组织的脱木质素转折点分别出现在155 min（脱除率71.3%）和135 min（脱除率78.4%），表明薄壁组织更易成浆。木质素荧光分布显示：维管束次生壁木质素优先脱除，而初生壁、胞间层和细胞角隅区域木质素浓度先增后减；薄壁组织初生壁和胞间层木质素浓度优先减少，细胞角隅区域也呈现先增后减趋势。根据蔗渣不同组织脱木质素差异性，在预处理或分段蒸煮进行调控为提高蔗渣浆质量提供参考。 |
| Abstract:The tissue heterogeneity of bagasse raw materials significantly affects the pulping performance. Different tissues composed of bagasse fiber cells (BF) and parenchyma cells (PC) were obtained by fractional separation and alkali cooking was carried out respectively to discuss the difference of cooking process in different tissue. The results showed that there were significant differences in Kappa value， black liquor lignin concentration， and delignification rate between 105 and 195 min. When the maximum cooking temperature was 160 ℃， the delignification turning points of vascular bundle tissue and parenchyma tissues appeared at 155 min (delignification rate of 71.34%) and 135 min (delignification rate of 78.45%)， respectively， indicating that parenchyma tissue was easier to form pulp. The fluorescence distribution of lignin showed that the lignin in the secondary wall of the vascular bundle tissue was preferentially removed， while the lignin concentration in the primary wall， intercellular layer and cell corner area increased first and then decreased. The lignin concentration in the primary wall and intercellular layer of the parenchyma tissue decreased preferentially， and the cell corner area also increased first and then decreased. According to the difference of delignification in different tissue of bagasse， the regulation of pretreatment or segmented cooking provides data reference for improving the quality of bagasse pulp. |
