The papermaking industry is a significant consumer of specialty chemicals, with Polyacrylamide (PAM) playing a pivotal role in optimizing various stages of production. From enhancing paper strength and quality to improving process efficiency and reducing environmental impact, PAM is an indispensable additive for modern paper mills. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier of industrial chemicals, is proud to offer high-grade Polyacrylamide designed to meet the stringent demands of the papermaking sector.

For papermaking professionals, understanding the specific functions of PAM can lead to significant improvements in product quality and operational cost-effectiveness. Let's explore how this versatile polymer contributes to the industry.

Key Applications of Polyacrylamide in Papermaking:

PAM's effectiveness in papermaking stems from its ability to influence the behavior of fibers, fillers, and other components within the paper slurry. Its high molecular weight and specific ionic properties allow it to act as:

  • Retention Aid: PAM significantly improves the retention of fine fibers and fillers (such as clay or titanium dioxide) within the paper sheet. By bridging these smaller particles, it prevents them from passing through the forming fabric, leading to reduced raw material loss and improved paper opacity and brightness.
  • Drainage Aid: It enhances the dewatering of the paper slurry on the paper machine, allowing water to be removed more quickly and efficiently. This leads to faster machine speeds, increased production capacity, and reduced energy consumption in the drying section.
  • Dry Strength Agent: PAM can improve the internal bonding of paper fibers, thereby increasing the dry strength of the finished paper. This translates to improved tensile strength, burst strength, and folding endurance.
  • Flocculant for Wastewater Treatment: Papermaking processes generate significant volumes of wastewater. PAM is widely used as a flocculant in the treatment of papermaking wastewater and white water, aiding in the removal of suspended solids and improving water recycling efficiency.

Types of PAM for Papermaking:

While different types of PAM can be used, specific grades are often preferred depending on the application:

  • Cationic Polyacrylamide (CPAM): Often favored for retention and drainage due to the negative charge of cellulose fibers. It effectively neutralizes these charges, promoting better interaction and retention.
  • Anionic Polyacrylamide (APAM): Can be used as a dispersant and also in specific retention and drainage applications, sometimes in conjunction with other aids.
  • Non-ionic Polyacrylamide (NPAM): Useful in applications where minimal charge interference is desired.

Procurement managers and R&D scientists in the papermaking industry should consider the specific requirements of their process. Factors like pulp type, filler used, and desired paper properties will influence the optimal PAM selection. Sourcing from a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures you receive products that meet stringent quality standards for consistent performance.
