The papermaking industry relies on precise chemical formulations to achieve high-quality paper products efficiently. Anionic Polyacrylamide (APAM) plays a crucial role as a functional additive, significantly enhancing key aspects of the papermaking process, including retention, drainage, and paper strength. As a leading manufacturer and supplier, we provide high-performance APAM tailored for the unique demands of paper mills.

The Function of APAM in Papermaking
In the papermaking process, APAM is primarily utilized for its ability to:

  • Improve Retention: APAM acts as a retention aid, helping to retain fine fibers, fillers (like clay and calcium carbonate), and other additives within the paper sheet. This is achieved through flocculation, where APAM bridges these small particles, preventing them from passing through the forming wire with the water. Enhanced retention leads to reduced material loss, improved paper formation, and cleaner white water systems.
  • Enhance Drainage: By promoting flocculation, APAM also facilitates the rapid release of water from the paper stock. This improved drainage allows for higher machine speeds and reduced energy consumption in the drying sections.
  • Increase Paper Strength: APAM can contribute to both the dry and wet strength of paper. By forming strong bonds with fibers, it reinforces the paper structure, improving its tensile strength, burst strength, and tear resistance. It can also act as a sizing agent, improving the paper's resistance to water penetration.
  • Aid in White Water Treatment: APAM helps clarify the white water loops in paper machines by flocculating suspended solids, allowing for efficient water recycling and reducing effluent discharge.

Choosing the Right APAM for Papermaking

The selection of APAM for papermaking applications depends on several factors:

  • Molecular Weight: A medium to high molecular weight APAM is typically preferred for retention and drainage aids, as it provides effective bridging between particles.
  • Charge Density: The anionic charge density needs to be compatible with the charge characteristics of the furnish (fibers, fillers, and other additives) used in the paper machine.
  • Product Purity: Ensuring low residual monomer content is vital for maintaining product quality and meeting environmental regulations.
