摘　　要：现代抄纸是一个水循环过程。助留剂直接改变白水的性质,对抄纸过程和成纸性质有十分重要的影响。常用助留剂已从单一聚丙烯酰胺逐渐过渡到微粒和超微粒系统。应用方面出现新的发展趋势:追求性价比更高的助留剂产品及系统、助留剂系统组份增多、助留系统化学品分别采购、加入点向网部移动等。Modern papermaking is a water circulation process. The retention aid affects the quality of white water and hence has an important impact on the papermaking process and paper quality. The retention system has also shifted from single polyacrylamide to microparticle reten- tion systems. New trend of development appears in the application： seeking for higher performance-price ratio retention aid product and system, increase in compositions in retention aid system, separate purchasing of retention system chemicals and shift of the addition points to the wire part.
