【摘要】:在正交實(shí)驗(yàn)的基礎(chǔ)上,結(jié)合抄紙實(shí)驗(yàn),運(yùn)用坐標(biāo)綜合評(píng)定法確定了相思木硫酸鹽法制漿的最佳蒸煮條件。實(shí)驗(yàn)結(jié)果表明,在用堿量15%(以Na2O計(jì))、硫化度30%、液比1∶4、蒸煮最高溫度165℃、升溫時(shí)間60 min、保溫時(shí)間120 min的條件下進(jìn)行硫酸鹽法蒸煮,所得紙漿得率52.25%,卡伯值17.9,黏度987.3 m L/g,裂斷長(zhǎng)9.32 km,抗張指數(shù)93.6 N·m/g,撕裂指數(shù)10.0 m N·m2/g,耐破指數(shù)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,
