研究阳离子瓜尔胶单元、二元、三元体系对碳酸钙和滑石粉加填的高得率浆造纸的助留助滤体系及剪切速率对三元体系的影响。结果表明,三元体系的助留助滤能力优于单元和二元;随着剪切速率的上升,助留效果变差;助滤效果先变差之后再提高。此外,滑石粉的留着效果比碳酸钙好。 The cationic guar gum unit, binary and ternary system of calcium carbonate and talc filled with high yield pulp papermaking filter aid retention and drainage system and the impact of the ternary system. The results show that the retention capacity of the ternary system is better than that of the unit and the binary system. With the increase of the shear rate, the effect of retention and retention becomes worse. The filter aid effect first deteriorates and then increases. In addition, talcum retention effect better than calcium carbonate.
