摘要
进行了尾叶桉木片硫酸盐法蒸煮,纸浆无元素氯漂白、打浆及配抄性能的探索,得出较合适的蒸煮条件为:用碱量(Na2O计)18%,硫化度25%,液比1∶4,升温1.75h,保温2.5h,最高温度168℃(120℃小放气),成浆卡伯值为22.58,得率45.2%。漂白采用ODQP四段漂,成浆白度达87.2%ISO。经瓦利打浆机打浆55m in可以打到35°SR。漂白桉木浆与甘化浆板配比为3∶7时,配抄70 g/m2的胶印书刊纸,可以达到A等的强度、白度和不透明度等指标的要求。
Eucalytus urophylla characteristics of pulping and papermaking were studied. As the kraft cooking conditions were alkali charge （ Na20） 18% , sulfidity 25%, wood to liquor ratio 1 ： 4,max temperature 168℃ for 2.5h, temperature rising period 1.75h,the pulp with Kappa number of 22.5 and yield of 45.2% was obtained. ODQP 4 stages ECF bleaching was used, the brightness of 87.2% ISO was reached. It took 55 minutes to reach 35°SR by Valley beater. At the furnish of eucalyptus pulp to bagasse mixed Chinese silver grass pulp of 3 ： 7 to make 70g/m^2 offset paper, the quality of the paper can reach A degree.
