The papermaking industry is a complex ecosystem where efficiency, quality, and cost-effectiveness are paramount. Among the myriad of chemical additives employed, polyacrylamide (PAM) plays a crucial role, significantly enhancing both the production process and the final product quality. As a key supplier of industrial chemicals, we understand the unique demands of the paper industry and offer tailored polyacrylamide solutions.

Polyacrylamide, particularly cationic and anionic variants, is widely utilized in papermaking for its ability to improve retention, drainage, and paper strength. In the wet end of the papermaking process, a slurry of pulp fibers, fillers (like calcium carbonate or clay), and other additives is formed. Efficiently retaining these valuable components within the paper sheet while rapidly draining water is essential for productivity and resource management.

Retention Aids: Cationic polyacrylamides, with their positive charge, are highly effective as retention aids. They adsorb onto the negatively charged surfaces of pulp fibers and fillers. This adsorption neutralizes surface charges and promotes bridging, causing smaller particles to aggregate with the larger fibers. As a result, more fines and fillers are retained in the sheet rather than being lost into the white water system, leading to:

  • Reduced material loss and improved yield.
  • Lower suspended solids in white water, simplifying water clarification and recycling.
  • Improved opacity and brightness of the paper.

Drainage Aids: PAM also acts as a drainage aid by enhancing flocculation of the fiber and filler components. The formation of larger flocs allows water to drain more freely through the forming sheet on the paper machine. This increased drainage rate leads to:

  • Higher machine speeds, boosting production output.
  • Reduced energy consumption in the drying section.
  • Improved sheet formation and uniformity.

Paper Strength Enhancement: In addition to retention and drainage, certain types of polyacrylamide can also improve the dry and wet strength of paper. By forming hydrogen bonds and physical entanglement with the cellulose fibers, PAM can act as a dry strength agent, increasing tensile strength, burst strength, and tear resistance. Wet strength agents are also critical for specific paper products.

For paper manufacturers, sourcing reliable and high-performance polyacrylamide is essential. We, as a dedicated manufacturer and supplier, ensure that our PAM products meet the stringent requirements of the paper industry. Our offerings include a range of cationic and anionic polyacrylamides specifically designed for retention, drainage, and strength improvement. We emphasize product consistency, competitive pricing, and timely delivery to support uninterrupted production cycles.

We understand that each mill has unique operating conditions and furnish types. Therefore, we offer technical support to help paper mills optimize their use of polyacrylamide, conducting trials and recommending the most suitable grades.
