The paper industry relies on a variety of chemical additives to optimize production processes and enhance the quality of the final product. Polyacrylamide (PAM), a highly effective water-soluble polymer, plays a crucial role in several stages of papermaking, primarily as a retention aid, drainage aid, and flocculant. As a prominent manufacturer and supplier of organic chemicals, NINGBO INNO PHARMCHEM CO.,LTD. offers high-performance polyacrylamide solutions tailored for the unique demands of the paper industry.

Polyacrylamide as a Retention and Drainage Aid

In the papermaking process, particularly on the paper machine, fine cellulose fibers, fillers (like calcium carbonate or kaolin clay), and sizing agents are suspended in water. Efficiently retaining these components and promoting rapid water drainage are critical for both product quality and machine efficiency. Polyacrylamide, especially cationic polyacrylamide (CPAM) and some anionic variants, excels in these roles:

  • Retention Aid: PAM acts by flocculating the fine particles and fillers, binding them to the larger cellulose fibers. This prevents these valuable materials from passing through the wire mesh of the paper machine, thus improving yield and reducing the load on the wastewater treatment system.
  • Drainage Aid: By forming larger flocs, PAM also enhances the rate at which water drains from the forming paper web. This allows for higher machine speeds, increased production output, and reduced energy consumption in the drying section.

Improving Water Clarification in Paper Mills

Beyond the paper machine, polyacrylamide is also vital for clarifying process water and treating mill effluent. It effectively removes suspended solids and fines from white water, allowing for recirculation and reducing freshwater intake. This not only conserves water but also recovers valuable materials that would otherwise be lost. Anionic polyacrylamide (APAM) is particularly effective in these clarification steps for its ability to flocculate positively charged or neutral suspended matter found in paper mill circuits.

Choosing the Right Polyacrylamide for Paper Making

The selection of polyacrylamide for papermaking depends on the specific stage and the type of fines and fillers used. Factors such as furnish composition, pH, and the desired performance (retention, drainage, or clarification) guide the choice between anionic, cationic, or sometimes non-ionic types. We offer a range of polyacrylamide products with varying molecular weights and charge densities to optimize performance in your paper mill. When you decide to buy polyacrylamide for paper applications, consider our high-purity grades for consistent results.
