摘要
本文通过采用基于透光脉动原理自制的PDA(Photometric Dispersion Analyzer)系统,研究了常用的助留剂,如阳离子聚丙烯酰胺,在新闻纸浆料悬浮液中所形成的絮团絮凝大小与新闻纸的留着、滤水及与新闻纸手抄纸匀度的关系。
In this paper, the flocculate size of several retention aids, such as polyacrylamide, formed in suspension of newspaper pulp was investigated and its effects on the retention, drainage and formation of newsprint furnish were also studied using self-made Photometric Dispersion Analyzer, a transmitted light fluctuation-based PDA system.
