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 is an important raw material in the paper industry and has excellent pulping and papermaking performance. The eucalyptus is used for the first time to study its pulping performance and provide theoretical data for the paper industry. The main results of the experiment are as follows: The optimum conditions for AS-AQ cooking of Family 123 were as follows: 25% of total alkalinity (calculated as Na2O), 0.5 of sulfation degree (calculated as Na2O), 0.08% of anthraquinone, The optimum conditions were as follows: dosage of 0.3%, holding time of 160 min, maximum cooking temperature of 170 ℃ and liquid ratio of 1: 4.5. The optimum conditions of family 200 were as follows: total alkalinity (calculated as Na2O) 23%, sulfitation degree (calculated as Na2O) Anthraquinone 0.08%, NP-10 dosage 0.3%, holding time 150min, the maximum cooking temperature 170 ℃, liquid ratio 1: 4.5.
