The paper industry relies on advanced chemical additives to optimize production processes and ensure high-quality output. Polyacrylamide (PAM), particularly anionic and cationic variants, plays a crucial role as a retention aid, drainage aid, and strength enhancer. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted polyacrylamide supplier, providing essential solutions for the papermaking sector.

The Importance of PAM in Papermaking

In the papermaking process, fine fibers, fillers (like calcium carbonate or kaolin), and other additives are suspended in water to form a slurry. Efficiently retaining these valuable components on the paper machine wire and ensuring good drainage are vital for product quality and economic viability. PAM contributes significantly to these aspects:

Retention Aid

PAM acts as a retention aid by bridging the fine particles (fibers and fillers) together. These bridged particles are larger and less likely to pass through the forming fabric of the paper machine. This leads to:

  • Improved Retention of Fines and Fillers: Maximizing the amount of valuable material that stays in the paper sheet.
  • Reduced Chemical Consumption: Less filler and fiber loss means lower raw material costs.
  • Cleaner White Water: Improved retention results in cleaner process water, which can be more effectively recycled.

Drainage Aid

By promoting flocculation and particle aggregation, PAM helps to create a more open sheet structure, allowing water to drain more rapidly from the forming paper web. This facilitates faster machine speeds and improves energy efficiency in the drying section.

Strength Enhancer

PAM can also improve the dry and wet strength of the paper by forming strong bonds between fibers. This is particularly important for specialized paper grades.

Choosing the Right PAM for Papermaking

The choice between anionic, cationic, or nonionic PAM depends on the specific furnish (pulp type and additives used) and desired paper properties:

  • Cationic PAM (CPAM): Often preferred due to the negative charge of cellulose fibers. CPAM effectively bridges fibers and fillers, enhancing retention and drainage.
  • Anionic PAM (APAM): Can be used in conjunction with cationic additives or in specific formulations where its properties are beneficial.
  • Amphoteric PAM: Offers versatility for complex furnishes.

We recommend performing trials to determine the optimal PAM type and dosage for your specific papermaking process. As a reliable supplier for water treatment chemicals and papermaking additives, we can assist with product selection.
