Papermaking polyacrylamide is used as retention aid, filter aid, leveling agent, etc. in the papermaking industry. The function of polyacrylamide used in papermaking can improve the strength of paper, improve the dehydration performance of slurry, increase the retention rate of fibers and fillers, and reduce the loss of raw materials and pollution to the environment.

The effect of use in papermaking depends on the average molecular weight, ionic properties, ionic strength and other copolymer characteristics of polyacrylamide. Nonionic polyacrylamide for papermaking is mainly used to improve the filterability of paper pulp, increase the paper strength of dry paper, and improve the retention rate of paper fibers and fillers; anionic polyacrylamide for papermaking is mainly used for dry and wet reinforcement of paper Agent and retention agent; cationic polyacrylamide for papermaking is mainly used for papermaking wastewater treatment and filter aid. In addition, special polyacrylamide for papermaking also has a good effect on improving the retention rate of fillers. In addition, papermaking-specific polyacrylamide is also used in papermaking wastewater treatment.
