【摘要】：在正交实验的基础上,结合抄纸实验,运用坐标综合评定法确定了相思木硫酸盐法制浆的最佳蒸煮条件。实验结果表明,在用碱量15%(以Na2O计)、硫化度30%、液比1∶4、蒸煮最高温度165℃、升温时间60 min、保温时间120 min的条件下进行硫酸盐法蒸煮,所得纸浆得率52.25%,卡伯值17.9,黏度987.3 m L/g,裂断长9.32 km,抗张指数93.6 N·m/g,撕裂指数10.0 m N·m2/g,耐破指数5.34 k Pa·m2/g。
[Abstract]:On the basis of orthogonal experiment and combining with paper-making experiment, the optimum cooking conditions of Acacia wood pulping by Kraft process were determined by using coordinate comprehensive evaluation method. The results showed that Kraft cooking was carried out under the conditions of 15% alkali (calculated as Na2O), 30 degree of vulcanization, 1: 4 ratio of liquid to liquid, 165 鈩，
