摘　　要：研究了膨润土用量、pH值、电导率、剪切力对阳离子瓜尔胶/膨润土二元体系的助留助滤性能的影响。研究表明:二元体系比单元体系有更好的助留助滤性能,更能抗pH值、电导率、剪切力的干扰;且能提高成纸的强度。The factors affecting the drainability and retention of deinked pulp papermaking of the dual polymer retention system, such as bentonite dosage, pH, conductivity and shearing strength were studied. The results show that pH, conductivity and shearing strength have little effect on the dual polymer retention system compared to the CHPG single retention system. Furthermore, the dual system can also improve the breaking strength of the paper product.
