The papermaking industry is a cornerstone of modern communication and packaging, demanding high standards for product quality and operational efficiency. Achieving these goals often involves the use of specialized chemical additives, with Polyacrylamide (PAM) being one of the most effective. NINGBO INNO PHARMCHEM CO., LTD. highlights the critical functions of PAM in optimizing papermaking processes and enhancing sustainability.

In papermaking, PAM primarily functions as a retention and drainage aid. During the formation of paper sheets on the wire, fine cellulose fibers, fillers (like calcium carbonate or clay), and sizing agents need to be retained within the sheet structure. Without effective retention, these valuable components pass through the forming fabric with the water, leading to material loss, reduced paper quality, and increased effluent load. PAM, through its bridging and flocculation mechanisms, aggregates these fine particles, helping them to bond with the larger fibers. This results in:

  • Improved Retention Rate: Higher retention of fibers and fillers leads to better opacity, brightness, and strength of the final paper product. It also reduces the amount of solids in the process water, which are then carried into the wastewater.
  • Enhanced Drainage: PAM also aids in the dewatering of the paper web on the paper machine. Faster drainage means the sheet can be processed at higher speeds, increasing production efficiency. It also reduces the energy required for drying the paper.

The effectiveness of PAM in these roles is directly linked to its molecular structure and charge. NINGBO INNO PHARMCHEM CO., LTD. offers a range of PAM products, including anionic (APAM), cationic (CPAM), and non-ionic (NPAM) types, each suited for different types of pulp and processing conditions. The correct selection ensures optimal performance for specific papermaking needs.

Furthermore, the papermaking process generates significant volumes of wastewater. This wastewater often contains suspended solids, dissolved organic matter, and residual chemicals. PAM plays a vital role in treating this effluent. By flocculating the suspended particles in the wastewater, PAM facilitates their removal, thereby reducing the organic load and turbidity of the discharged water. This contributes to the industry's efforts in environmental protection effects and compliance with discharge regulations.

The use of PAM in papermaking not only enhances product quality and production efficiency but also supports environmental sustainability by improving wastewater treatment. As the industry continues to innovate, the role of advanced chemical solutions like Polyacrylamide will remain indispensable for meeting both performance and environmental objectives. NINGBO INNO PHARMCHEM CO., LTD. is proud to be a supplier of these essential materials, supporting the growth and sustainability of the global paper industry.
