The papermaking industry relies on a range of chemical additives to optimize product quality, process efficiency, and environmental compliance. Polyacrylamide (PAM) is a vital component, playing a crucial role in improving filler retention, enhancing paper strength, and managing wastewater. As a dedicated Polyacrylamide supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality PAM tailored for the unique demands of the paper industry.

PAM's effectiveness in papermaking stems from its ability to act as a flocculant and bridging agent. In the papermaking process, fine fibers and fillers are suspended in water. PAM helps to aggregate these components, leading to significant improvements in various aspects of production.

Enhancing Filler and Fiber Retention

Fillers (like calcium carbonate or kaolin clay) and fine fibers are essential for paper properties such as opacity, brightness, and smoothness. However, they can easily be lost with the water during the sheet formation and dewatering process. PAM, particularly cationic or high molecular weight anionic types, acts as a retention aid:

  • Bridging Mechanism: PAM polymer chains adsorb onto the surface of fibers and fillers. These long chains then bridge between multiple particles, forming larger, more complex flocs.
  • Improved Retention: These larger flocs are more easily retained on the forming paper web, reducing the loss of valuable fillers and fines into the white water system. This leads to better material utilization and can reduce effluent load.
  • Enhanced Drainage: By promoting the formation of larger particles, PAM can also improve the drainage of water from the paper web on the paper machine, leading to higher machine speeds and reduced energy consumption in drying.

When seeking to buy Polyacrylamide for retention aids, consider the specific paper grade and furnish being used. Consulting with a knowledgeable Polyacrylamide manufacturer like us can help identify the optimal product. We offer various grades suitable for improving your paper retention performance.

Improving Paper Strength

PAM can also contribute to the dry and wet strength of paper:

  • Dry Strength: By bridging fibers more effectively, PAM can enhance the inter-fiber bonding, leading to increased tensile strength, burst strength, and stiffness in the final paper product.
  • Wet Strength: Certain modified PAMs can also impart wet strength properties, making paper more resistant to disintegration when wet.

Wastewater Treatment in Papermaking

The papermaking process generates significant wastewater containing residual fibers, fillers, and dissolved organic matter. PAM plays a crucial role in treating this effluent:

  • Flocculation of Solids: PAM efficiently flocculates suspended solids in paper mill wastewater, allowing for their removal through sedimentation or filtration. This is vital for meeting environmental discharge regulations.
  • Sludge Dewatering: The sludge generated from paper mill wastewater treatment can also be dewatered effectively using appropriate grades of CPAM or APAM.
