摘要
探究了添加非离子型和阳离子型瓜尔胶复配在卷烟纸网下白水封闭循环回用过程中对卷烟纸物理性能的影响。实验结果表明:适当的白水循环能够提高填料的留着率,当白水封闭程度为40%时,填料的留着率达到最理想的41.3%;然而,随着封闭程度进一步加深,纸机环境变得恶劣,留着率最终下降到33.0%,纸张的机械强度、白度及不透明度也随之下降。而在白水回用过程中加入非离子和阳离子型瓜尔胶可明显提高卷烟纸的物理强度,当它们的添加量分别为0.3%和0.1%时,助留和增强效果最优,填料的留着提升至51.4%,卷烟纸的抗张强度和撕裂指数分别达到为46.7 N.m/g和1.98 mN.m2/g。
This paper investigated the effect of the proportion of white water circulation and the amount of non-ionic and cationic guar gum on filler retention.The results showed that proper white water circulation can improve the retention of fillers.When the sealing degree of white water is 40%,the retention rate of fillers reached the optimal 41.3%.However,further deepening the sealing degree made the paper machine environment harsh,and the filler retention rate eventually dropped to 33%.The mechanical strength,whiteness and opacity of the paper also decreased.When non-ionic and cationic guar gum were used as additives,various properties of the paper were optimized.The retention and reinforcement effects were achieved best when their addition amounts were 0.3%and 0.1%,respectively.The retention of filler was increased to 51.4%,and the tensile strength and tear index was 46.7 N·m/g and 1.98 mN·m2/g,respectively.
