该文介绍了聚丙烯酰胺(PAM)类增强剂的技术演变和通过新的聚合方法使聚合物的相对分子质量分布变得狭窄的新型PAM类纸张增强剂;同时介绍了将具有不同絮凝性能的PAM类增强剂合用而使匀度和絮凝性能够兼顾的新型配方(即2液混合配方)。
This paper describes the technological evolution of polyacrylamide (PAM) reinforcements and the new type of PAM paper enhancer that narrows the relative molecular mass distribution of the polymer by a new polymerization method. At the same time, PAM class enhancer combination of formation and flocculation can take into account the new formula (that is, two-liquid mixing formula).
