The papermaking industry relies heavily on efficient chemical processes to produce high-quality paper products. Among the critical additives used, Polyacrylamide (PAM) plays a vital role, particularly as a retention aid and drainage enhancer. Its ability to flocculate fine particles and improve water removal makes it indispensable for optimizing paper machine performance and product quality. As a leading polyacrylamide manufacturer and supplier in China, we provide tailored PAM solutions for the papermaking sector.

In papermaking, fine fibers, fillers (like clay and calcium carbonate), and other additives are suspended in water to form a slurry. The goal is to retain as much of these valuable components as possible within the paper sheet while efficiently removing water. This is where PAM demonstrates its significant value:

  • Retention Aid: PAM, especially anionic and cationic varieties, acts as a flocculant for the fine particles in the pulp slurry. By forming larger, more stable flocs, it increases the probability that these fine particles, including fibers and fillers, will be retained on the forming wire of the paper machine. This leads to:
    • Reduced loss of valuable raw materials, contributing to cost savings.
    • Improved opacity and brightness of the final paper product.
    • Cleaner white water systems, reducing effluent load and pollution.
  • Drainage Enhancer: The flocculation action of PAM also helps to release water from the pulp slurry more rapidly. As water drains from the forming sheet, the flocs created by PAM create preferential pathways, allowing water to escape more easily. This results in:
    • Faster machine speeds, increasing production output.
    • Reduced energy consumption in the drying section.
    • Improved sheet formation and consolidation.

The choice between anionic, cationic, or non-ionic PAM often depends on the specific characteristics of the pulp furnish, the type of paper being produced, and the existing chemical additives in the process. Cationic PAM is often favored for its strong affinity to negatively charged cellulose fibers and fillers. However, anionic and non-ionic PAM can also be effective, sometimes used in combination or in specific process conditions.
