The paper industry is a sector where the precise application of chemical additives can dramatically influence product quality, production efficiency, and operational costs. Among these vital chemicals, cationic polyacrylamide (CPAM) stands out for its multifaceted benefits, particularly in enhancing retention and drainage. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-quality CPAM tailored for the demanding needs of the paper making retention aid sector.

Cationic polyacrylamide is a synthetic polymer with a high molecular weight and positively charged functional groups. In the papermaking process, pulp slurry contains fine fibers, fillers (like calcium carbonate or clay), and other additives. These components often possess a negative surface charge, which can lead to their loss during the sheet formation and dewatering stages. CPAM acts as a flocculant and retention aid by neutralizing these negative charges and forming bridges between particles. This aggregation traps finer particles and fillers within the fiber matrix, significantly improving retention rates.

The benefits of using CPAM as a retention and drainage aid are substantial. Firstly, it leads to improved retention of fines and fillers. This not only reduces material loss into the whitewater system but also contributes to better sheet formation, increased paper strength (both wet and dry), and improved optical properties like brightness and opacity. Secondly, CPAM enhances drainage. By forming larger, more permeable flocs, it allows water to escape more easily during the pressing and drying stages. This faster drainage can lead to increased machine speed and reduced energy consumption in the drying process, boosting overall production efficiency.

Beyond retention and drainage, CPAM also plays a role in wastewater treatment within paper mills. The whitewater generated during production contains residual fibers and fillers. CPAM can be used to clarify this whitewater, allowing for its recycling back into the process, which conserves water and reduces the effluent load. This demonstrates the versatility of polyacrylamide for paper making beyond its direct role in sheet formation.
