【摘要】 减轻废纸在回收利用过程中的强度降低的趋势对废纸的再生循环利用有着极其重要的作用,本文对季铵型阳离子淀粉在废纸回用过程中的增强效果进行了初步研究。研究表明,当阳离子淀粉用量为1.0%,温度为60℃,反应时间为2.0h,pH值为5时增强效果最佳。更多还原

【Abstract】 It is very important to reduce the trendence that strenght of paper is lower and lower in the recycling of wastepaper. This paper preliminarily studied the strengthening of the quaternary ammonium type cationic starch on wastepaper recycling. The results showed that in the conditions of cationic starch charge of 1.0% and reacting temperature at 60℃ for 2.0 hours, it enhanced the best.更多还原
