阳离子石油树脂施胶剂留着效率及影响因素的研究

Study on the Factors Affecting Retention of Cationic Petroleum Resin Sizes

本文利用Britt动态滤水仪与紫外分光光度计相配合,测定了阳离子石油树脂施胶剂在漂白麦草浆中的留着效率,初步探讨了pH值、胶料用量、明矾用量、PAE用量、碳酸钙加填量、剪切力等因素的影响。实验结果表明,在加入适量PAE的情况下,该施胶剂在中性条件下有较好的留着率。

The retention of dispersed cationic petroleum resin size in bleached wheat straw pulp was determined by DDJ and ultraviolet spectrophotometer. The affecting factors such as pH value, shearing force , the dosages of size, aluminum sulphate, PAE and calcium carbonate were discussed, and the result indicated that the size had high retention in the above pulp at neutral condition with the addition of PAE.
