The papermaking industry relies on efficient processes and high-quality raw materials to produce superior paper products. Polyacrylamide (PAM) plays a significant role as a functional additive, enhancing key stages of paper production, from pulp processing to finished paper quality. As a leading supplier of specialty chemicals, we understand the critical need for effective papermaking aids like PAM.

How PAM Benefits the Paper Industry

PAM acts primarily as a retention and drainage aid in the papermaking process. Its high molecular weight and charge characteristics allow it to interact with cellulose fibers, fillers, and pigments:

  • Retention Aid: PAM helps to retain fine fibers and fillers within the paper web during formation. This improves the yield of raw materials, reduces losses into the white water system, and enhances the opacity and brightness of the final paper. Anionic and cationic PAM are often used, sometimes in combination, depending on the pulp and filler characteristics.
  • Drainage Aid: By promoting flocculation of the pulp slurry, PAM facilitates faster dewatering of the paper web on the paper machine. This allows for higher machine speeds and reduced energy consumption in the drying stages.
  • Dry and Wet Strength Enhancement: PAM can improve the internal bonding of fibers, leading to increased tensile strength, bursting strength, and folding endurance of the paper. Certain formulations also contribute to improved wet strength.
  • Sludge Dewatering: In the paper mill's wastewater treatment plant, PAM is crucial for dewatering the generated sludge, similar to its application in other industries.

Choosing the Right PAM for Papermaking

The selection of PAM for papermaking applications often depends on the specific papermaking conditions, including the type of pulp, fillers used, water chemistry, and desired paper properties. While cationic PAM is often favored for its strong interaction with negatively charged cellulose fibers and fillers, anionic and nonionic PAM may also be employed depending on the process requirements.
