以杨木P-RC APMP为原料,对其进行筛分,并对P-RC APMP细小纤维与碳酸钙进行絮聚。在CPAM与CPAM/膨润土两种体系下,研究不同CPAM添加量对细小纤维-碳酸钙浆料的电性、共絮聚团表面电荷、白水阳离子需求量、留着性能的影响,并研究CPAM添加量与膨润土用量对细小纤维-碳酸钙共絮聚团的大小及分布的影响。结果表明:与CPAM单元体系相比,CPAM/膨润土微粒助留体系的Zeta电位变化幅度更小、共絮聚团的表面电荷更低;在CPAM单元体系与CPAM/膨润土微粒助留体系中,随着CPAM添加量与膨润土添加量的不断增加,共絮聚团的平均弦长都在不断增大。
Poplar P-RC APMP was used as raw material to sieve it, and the P-RC APMP fines and calcium carbonate were flocculated. Under CPAM / CPAM / Bentonite system, the effect of different CPAM dosage on the electrical properties, the surface charge of co-flocculation, the demand of white water cation and retention properties of finer fiber-calcium carbonate slurries were investigated. Effect of Amount and Bentonite on the Size and Distribution of Co - agglomeration of Fine Fibers - Calcium Carbonate. The results showed that compared with the CPAM unit system, the change of Zeta potential of the CPAM / bentonite particle retention system was smaller and the surface charge of co-flocculation was lower. In CPAM unit system and CPAM / bentonite particle retention system, With the increasing amount of CPAM and the amount of bentonite added, the average chord length of co-flocculation is continuously increasing.
