摘　　要：研究了剪切力和CPAM、阳离子淀粉、硼改性硅溶胶用量对硼改性硅溶胶与阳离子淀粉或CPAM组成不同助留助滤体系的助留助滤效果的影响;同时研究了硫酸铝用量、pH值及电解质用量对助留助滤效果的影响。研究结果发现:阳离子淀粉/硼改性硅溶胶微粒助留体系的抗剪切能力优于阳离子淀粉一元助留体系。阳离子聚合物/硼改性硅溶胶微粒助留助滤体系的助留助滤效果优于一元助留助滤体系,同时大大地改善了纸页的匀度。阳离子淀粉/硼改性硅溶胶微粒助留助滤体系在pH值4～8时,以及在松香施胶体系中硫酸铝用量≤3%时较为适用,该体系抗电解质干扰能力强。The paper investigates the influence of shearing force and CPAM, cationic starch and the dosage of boron modified silica sol on the retention and drainage effect in different retention and drainage systems by boron modified silica sol and cationic starch or CPAM; it also investigates the influence of the dosage of aluminum sulfate, pH value and the dosage of electrolyte on the retention and drainage effect. The findings show that the sheer resistant performance of the cationic starch/boron modified silica sol particulate retention system surpasses that of the sole cationic starch system. The retention and drainage effect of cationic polymer / boron modified silica sol particulate retention and drainage system surpassed that of the sole retention and drainage system and the formation of the paper sheet was improved remarkably. When the pH value of cationic starch boron modified silica sol particulate retention and drainage system was between 4 and 8 and the dosage of aluminum sulfate was≤3% in the colophony sizing system the result was the best. The electrolyte disturbance resistance performance of the cationic starch / boron modified silica sol particulate retention and drainage system was desirable.
