摘　　要：研究了聚氧化乙烯与五种不同辅助剂--凹凸棒黏土、锂基膨润土、镁铝硅酸凝胶、酚醛树脂、硅溶胶组成的二元助留体系的助留助滤性能。结果表明:当聚氧化乙烯用量为0.01%时,五种不同辅助剂对浆料打浆度、细小组分留着率、填料留着率及其抗剪切性能、纸浆白度的影响是,PEO-硅溶胶体系、PEO-酚醛树脂体系性能最好,PEO-锂基膨润土、PEO-硅酸镁铝凝胶次之,PEO-凹凸棒黏土最差。The retention and drainage performance of a dual system were studied. The system was composed of PEO and five additive materials-- attapulgite, lithium base bentonite, aluminum-magnesium silicate gel, phenolic resin and silica sol. The results show that when PEO dosage is 0.01, the effects on beating degree, retention rate of fines and fillers, anti-shear properties and whiteness of bleached pulp are ranked with phenolic resin system and silica sol system being most effective, then lithium base bentonite system, and attapulgite system least effective.
