对合成的乙烯基甲酰胺阳离子高聚物在碱性条件下作为新型助剂的施胶效果进行了研究,采用凝胶渗透色谱法(GPC)和聚电解质滴定法标定;通过电子扫描显微镜(SEM)和化学分析电子光谱(ESCA)分析,观测到该聚合物的分子能够与松香胶形成一种含特殊结构的物质,该结构能够使松香胶粒子在碱性条件下稳定存在。研究结果说明该聚合物可以作为碱性条件下松香胶的助留剂。
The sizing effect of the synthesized vinylformamide cationic polymer as a new additive under alkaline conditions was studied, and it was determined by gel permeation chromatography (GPC) and polyelectrolyte titration. The scanning electron microscopy (SEM) ) And chemical analysis of electron spectroscopy (ESCA) analysis. It is observed that the polymer molecules can form a special structure with rosin gum, which can make the rosin particles stably exist under alkaline conditions. The results show that the polymer can be used as retention aid for rosin gum under alkaline conditions.
