摘　　要：针对在采用造纸法抄造无石棉密封材料过程中纸料留着及滤水困难,进行研究发现:硫酸铝体系能有效地提高体系细小组分的留着,改善浆料滤水,但随着添加量增加,体系有由碱性向酸性过渡的趋势;CPAM单组分体系中,添加量在0.08%时助留助滤效果最好;在CPAM/膨润土微粒体系中,CPAM添加量0.12%、膨润土添加量0.2%时,体系助留助滤效果最佳。且在较高的CPAM用量下,CPAM/膨润土微粒体系能更有效地改善浆料的滤水性能。Investigation in accordance with bad retention and drainage performance in the papermaking process for forming nonasbestos sealants found that aluminum sulfate system effectively improved the retention and drainage performance of the slurry, but as the charge of aluminum sulfate increased, there was a tendency of the system turning from alkaline to acidity; in the CPAM onecomponent system, the addition amount of 0.08% was the best for the system; in CPAM/ bentonite particle system, when the CPAM addition reaches 0.12% and the bentonite 0.2%, the effect of retention and drainage attained the best. Meanwhile, under a higher dosage of CPAM, the CPAM/bentonite particle system had a better improvement on the pulp drainage performance.
