| 摘 要： | 针对麦草高得率制浆废液中有机物的活泼性羟基等进行季铵化改性,并对改性条件(如pH、醚化剂用量、时间、温度及改性产物的浆内添加量)进行了正交实验,考察应用于OCC废纸浆浆内添加后成纸的物理性能,探究改性产物的颗粒电荷需求量及对细小纤维首程留着率的影响。结果显示,季铵化改性的最佳工艺条件为:pH11,醚化剂用量30%(对绝干废液固含量),反应时间2h,温度70℃;当改性产物浆内添加量提高到12%时,成纸的各项物理强度性能均有明显的增强,且对提高浆料的细小纤维留着率有着积极的作用。

| Abstract: | The quaternized reaction was carried out between hydroxyl group of organics in wheat straw high yield pulping wastewater and CHPTMAC.And the modification factors of pH,etherizing agent dosage,reaction time,temperature and internal adding dosage were studied by orthogonal experiment through the test of paper physical properties.At the same time,colloid titration of modifier and the effects of internal adding dosage on fines' retention were discussed.The results showed that the optimum quaternized modificatio... |
