The papermaking industry relies heavily on chemical additives to enhance product quality, optimize production processes, and manage water usage effectively. Polyacrylamide (PAM), a versatile polyelectrolyte, plays a crucial role in these aspects. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality polyacrylamide, with cationic polyacrylamide (CPAM) being particularly beneficial for the demanding requirements of modern paper mills. This water treatment chemical not only aids in water clarification but also significantly improves paper properties.

In the papermaking process, maintaining optimal retention of fine fibers and fillers is critical for both product quality and economic efficiency. CPAM functions as an excellent retention aid by effectively bridging these small particles. Its cationic charge attracts negatively charged fibers and fillers, forming larger agglomerates that are retained within the paper sheet rather than being lost in the white water. This improves the yield of valuable materials and reduces the load on wastewater treatment systems. The use of CPAM as a papermaking retention aid directly translates to improved paper quality and reduced material costs.

Beyond retention, CPAM also acts as a dry strength agent. By promoting better fiber-to-fiber bonding, it enhances the overall physical strength of the paper, including tensile strength, burst strength, and fold endurance. This allows manufacturers to potentially reduce the use of other, more expensive strength additives or to achieve higher strength specifications with the same fiber furnish. This is a key advantage for efficient industrial solid liquid separation within the papermaking cycle.

The role of polyacrylamide extends to water management within the mill. CPAM is instrumental in treating white water, which is water recycled from the paper machine. By flocculating suspended solids in the white water, CPAM improves its clarity, allowing for greater reuse within the process. This not only conserves water resources but also reduces the volume of effluent that needs to be discharged. For sectors like mining or oil and gas, where water is also a critical resource, similar flocculation principles apply.

The efficient application of CPAM in papermaking also involves its use as a sludge dewatering agent for the sludges generated during the paper manufacturing process. This ensures that waste streams are managed efficiently, further contributing to the sustainability of papermaking operations. As a highly effective flocculant, it simplifies many of the complex separation challenges faced daily.
