  • The Role of Ionic Charge in Polyacrylamide's Performance in Papermaking

    Polyacrylamide (PAM) is a critical component in modern papermaking, widely used for its ability to act as a retention agent, filter aid, and leveling agent. While its general benefits are well-known—such as improving paper quality, enhancing pulp dewaterability, and reducing raw material consumption—one aspect that plays a particularly pivotal role in its performance is the ionic charge. The ionic...
