摘要

形态特征和化学近似值分析表明，它是书写和印刷级纸的合适原料。在活性碱(如Na2O)用量为12%、制浆温度为130℃、蒸煮时间为120 min、料液比为1:4的条件下，kappa值为17.38、筛选废品率为0.9%，制浆率为43.58%。生物碱法制浆时，纸浆得率略有下降，但纸浆亮度、拉伸指数、破裂指数和双折次数分别比纯碱法制浆提高4.1%、24.94%、14.03%和48.45%。在乙醇-纯碱法制浆过程中，纸浆得率、纸浆亮度、拉伸指数、破裂指数和双折次数分别比纯碱法制浆提高3.9%、6.6%、32.18%、35.40%和77.31%。

Effects of Ethanol Addition and Biological Pretreatment on Soda Pulping of Eulaliopsis binata

Morphological characteristics and proximate chemical analysis of E. binata showed it as a suitable raw material for writing and printing grade paper. Maximum pulp yield (43.58%) of kappa number 17.38 with 0.9% screening rejects was obtained at 12% of active alkali (as Na2O) pulping temperature 130°C, cooking time 120 min and solid to liquor ratio 1:4. During bio-soda pulping of E. binata, pulp yield decreased slightly while pulp brightness, tensile index, burst index and double fold numbers were improved by 4.1%, 24.94%, 14.03% and 48.45% respectively compared to soda pulping. During ethanol-soda pulping of E. binata, pulp yield, pulp brightness, tensile index, burst index and double fold numbers were improved by 3.9%, 6.6%, 32.18%, 35.40% and 77.31% respectively compared to soda pulping.
