摘要
桉木是造纸工业生产的重要原料,具有优良的制浆造纸性能,本研究首次采用粗皮桉为原料,研究其制浆性能,为造纸工业生产提供理论数据。实验的主要结果如下:家系123粗皮桉AS-AQ法蒸煮最佳工艺条件为总碱量(以Na2O计)25%,亚硫酸化度(以Na2O计)0.5,蒽醌0.08%,NP-10用量0.3%,保温时间160min,最高蒸煮温度170℃,液比1∶4.5,家系200的最佳工艺条件为总碱量(以Na2O计)23%,亚硫酸化度(以Na2O计)0.50,蒽醌0.08%,NP-10用量0.3%,保温时间150min,最高蒸煮温度170℃,液比1∶4.5。
Eucalyptus pellita is an important raw material in papermaking industry. This research discussed the AS - AQ pulping performance of Eucalyptus pellita as a new resource in papermaking industry. The optimal pulping conditions are as follows： for family 123 ： dosage of alkali （as Na20） is 25% ; sulfitation is 0. 50 ; dosage of NP - 10 is 0.3 % ;dosage of AQ is 0.08% ; time to maximum temperatare is 160min;maximum temperature is 170~C ; liquor to wood ratio is 4.5：1 ; for family 200 ： dosage of alkali （ as Na20） is 23% ; sulfitation is 0.50 ;dosage of NP - 10 is 0.3 % ;dosage of AQ is 0.08% ; time to maximum temperature is 150min;maximum temperature is 170°C ; liquor to wood ratio is 4.5： 1.
