摘要
对红麻酸法制浆生产文化用纸进行了研究。通过对红麻的全秆 芯秆和韧皮部进行化学成分分析及正交试验确定出红麻全秆亚硫酸氢镁法蒸煮的最佳工艺条件 :总酸 5 .6 % ,最高温度 16 0℃ ,保温时间 12 0min ,酸比 1.5 ,液比 1∶5。在此条件下蒸煮所得浆料的细浆得率 4 8.3% ,卡伯值 4 2 .1,粘度 94 8.6mL/g ,原浆白度为5 1.4
How to produce kenaf pulp by bisulfite was studied in this paper. The stalk, phloem, xylem of kenaf were analyzed and a series of experiments were done . The optimum parameters for pulping were gotten as follows: TA 5.6%, temperature 160℃, heat preservation time 120min, CA/FA 1.5, liquor ratio 1∶5, and the yield of screened pulp 48.3%, kappa number 42.1, viscosity 948.6mL/g, rightness 51.4%ISO.
