摘要
本试验以苇叶部分代表细小纤维和杂细胞样品,以苇秆部份代表较长纤维样品,进行硫酸盐法常规蒸煮,文章第一部分探讨了两组样品原料形态和化学组成的差异,第二部分为蒸煮中耗碱与得率的差异。
In this study, reed leaf portion rich in nonfiber cells such as parenchyma and epidermis cells etc. and reed stalk portion rich in fiber cells are kraft-cooked scpcratcly. The cell morphology and chemical composition , the characteristics of alkaline consumption arc compared. The result showed that hcmi-cellulose acid-soluble lignin, ash, silicon, 1% NaOH extract of leaf portion are higher and the cellulose content is lower than stalk portion. Main alkaline consumption reaction took place at initial stage of cooking for leaf portion, but for stalk portion it took place at second stage. The dclignification and carbohydrates dissolving are discussed.
