摘要
以脂肪酸、树脂酸、三油酸甘油脂为模型物,模拟了马尾松TMP造纸过程中造成树脂障碍的主要成分。通过对比研究马尾松TMP树脂和混合树脂模型物的胶体粒径分布与Zeta电位特性,对模型物的模拟可行性进行了评价。分析了各组分模型物的胶体粒径,重点探讨了pH值、温度、电解质浓度对各模型物胶体颗粒表面电荷、分散质粒子的存在形式和稳定性的影响。
The main components which can cause pitch trouble in the process of paper making with Masson pine TMP was simulated by using fatty acid, resin acid and oleic triglyceride as model materials. The feasibility of using mixed resin model materials to simulate Masson TMP resin was evaluated based on the comparison of colloidal particle size distribution and zeta potential between mixed resin model materials and TMP resin. The particle size of models of different component was analyzed and the effect of pH value ,temperature and consistency of electrolyte on the stability ,being form and surface change of the colloidal particles of each models was discussed.
