The paper industry relies heavily on a range of chemical additives to optimize production processes and product quality. Among these, polyacrylamide (PAM) has proven to be a remarkably versatile and effective material, particularly cationic polyacrylamide (CPAM). CPAM acts as a key additive in papermaking, enhancing crucial aspects like paper strength, fiber retention, and water management within the mill.

In papermaking, efficient retention of fine fibers and fillers is vital for both product quality and economic viability. Fines and fillers, if not retained, are lost into the whitewater system, leading to material waste and increased effluent load. CPAM, with its positively charged polymer chains, effectively neutralizes the negative charges present on cellulose fibers and fillers. This electrostatic interaction, along with bridging mechanisms, helps these small particles to agglomerate into larger flocs that are more easily retained within the paper web. This improves the overall efficiency of the papermaking process, reduces raw material consumption, and minimizes environmental pollution from whitewater discharge.

Furthermore, CPAM plays a significant role in improving the physical properties of the paper itself. As a paper strengthener, it forms bonds that enhance both the dry and wet strength of the paper. This is crucial for producing durable paper products that can withstand various handling and application conditions. The additive also acts as a drainage aid, facilitating the rapid removal of water from the pulp slurry during sheet formation. This faster dewatering leads to increased production speeds and reduced energy consumption in the drying stages.

Beyond its direct role in paper formation, CPAM is also instrumental in managing water within the mill. In the deinking process for recycled paper, CPAM helps in flocculating ink particles, making them easier to remove and improving the brightness and cleanliness of the recycled pulp. Effective water management, including the treatment of whitewater and the reduction of suspended solids, is critical for sustainability and cost reduction in the paper industry. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality CPAM that meets the demanding requirements of modern paper mills, contributing to both superior product output and more efficient resource utilization.
