While polyacrylamide (PAM) is widely recognized for its critical roles as a retention and drainage aid in the papermaking industry, its utility extends far beyond these primary functions. NINGBO INNO PHARMCHEM CO.,LTD. provides advanced PAM solutions that offer a comprehensive suite of benefits, addressing multiple challenges within the paper manufacturing lifecycle.

One of the significant, yet often understated, roles of PAM is its function as a dispersant. In paper production, ensuring an even distribution of fibers and fillers is essential for a uniform sheet. PAM, particularly certain low molecular weight cationic variants, effectively prevents the agglomeration of fibers, leading to improved sheet formation. This contributes to enhanced paper softness and a more consistent surface finish, which are crucial for high-quality printing and writing papers, as well as for the tactile qualities of tissue products. This aspect directly supports optimizing wet end chemical efficiency and improving overall paper uniformity.

Furthermore, PAM serves as an effective dry strength agent. By promoting better interfiber bonding, it can significantly increase the tensile strength, burst strength, and tear resistance of the paper. This is particularly valuable when aiming to enhance paper strength with polymers, allowing for the reduction of more expensive strength additives or the use of lower basis weights without compromising performance. This capability is vital for packaging materials and specialty papers that require robust physical properties.

The papermaking process also generates considerable wastewater, and here too, PAM proves invaluable. As a flocculant, it is highly effective in treating the effluent from paper mills. By aggregating suspended solids, fines, and other pollutants in the wastewater, PAM facilitates their removal through sedimentation or filtration. This not only helps paper mills meet environmental discharge regulations but also allows for more efficient water recycling within the mill, contributing to water conservation and reduced environmental impact. This application underscores the role of PAM in making paper production more sustainable.
