The papermaking industry relies on a complex array of chemicals to produce high-quality paper efficiently and sustainably. Among these essential additives, Polyacrylamide (PAM) stands out for its multifaceted role in enhancing crucial aspects of the papermaking process. NINGBO INNO PHARMCHEM CO.,LTD. discusses the significant impact of PAM, especially cationic polyacrylamide (CPAM), on papermaking efficiency.

In the papermaking process, the retention of fine fibers, fillers, and pigments within the paper web is critical for both product quality and economic viability. Inefficient retention leads to material loss and affects the optical and physical properties of the paper. CPAM acts as a highly effective retention aid. Its cationic charge attracts and binds negatively charged cellulose fibers and fillers, forming larger particles that are less likely to pass through the forming wire. This results in improved retention rates, reduced material waste, and a cleaner white water system.

Furthermore, PAM plays a vital role in improving drainage. As the wet paper web moves along the papermaking machine, rapid and efficient removal of water is essential for high production speeds. CPAM helps to flocculate the fines and fillers in a way that opens up the fiber network, allowing water to drain more freely. This enhanced drainage capability contributes to increased machine speed and reduced energy consumption in the drying sections.

Beyond retention and drainage, PAM is also employed as a dry strength agent. By promoting interfiber bonding, it increases the tensile strength, burst strength, and stiffness of the final paper product. This allows papermakers to potentially reduce the amount of expensive virgin fiber used or to achieve higher performance characteristics with recycled fiber inputs.

The versatility of PAM in papermaking also extends to its use in sizing, as a coating additive, and in wastewater treatment for the mill itself. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the importance of selecting the right grade of PAM – whether it's a CPAM with specific charge density or molecular weight – to optimize performance for particular grades of paper and machine conditions. For papermaking operations looking to boost their production efficiency, improve paper quality, and manage resources effectively, incorporating advanced polyacrylamide powder solutions from NINGBO INNO PHARMCHEM CO.,LTD. is a strategic advantage.
