The papermaking process is a complex operation that involves the suspension and formation of cellulose fibers and various additives into a cohesive sheet. Efficient retention of fine fibers, fillers, and sizing agents is vital for both product quality and economic viability. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes the significant contribution of Polyacrylamide (PAM) as a high-performance retention aid, improving drainage and overall paper strength.

In papermaking, retention aids are chemical additives that promote the retention of fine particles, such as cellulose fibers, pigments, and fillers, within the paper sheet during formation and dewatering. Polyacrylamide, particularly cationic PAM, is highly effective in this role. Its positively charged polymer chains interact with the negatively charged surfaces of fibers and fillers, forming micro-flocs that are more easily retained on the forming fabric. This improves the efficiency of the dewatering process, allowing water to drain more quickly from the paper web, which in turn increases the machine speed and reduces energy consumption in the drying section. As a premier paper making retention aid, PAM is indispensable for modern paper production.

The benefits of incorporating Polyacrylamide into the papermaking process extend beyond improved retention and drainage. Enhanced filler retention, for instance, leads to better opacity and printability of the final paper product. Furthermore, PAM can significantly improve the dry strength properties of paper, such as tensile strength and burst strength, by promoting better fiber-to-fiber bonding. This can allow for the use of less fiber or lower-grade fibers, leading to cost savings. The selection of the appropriate molecular weight and charge density of PAM is critical for optimizing these outcomes, and NINGBO INNO PHARMCHEM CO.,LTD. offers a diverse portfolio to meet these needs.
