The pulp and paper industry relies on specialized chemicals to optimize production processes and ensure high-quality output. Polyacrylamide (PAM), a versatile water-soluble polymer, plays a significant role in papermaking, primarily as a retention aid, drainage aid, and strength enhancer. NINGBO INNO PHARMCHEM CO.,LTD., a trusted PAM manufacturer, provides high-quality solutions to boost efficiency and product quality in paper mills.

PAM as a Retention Aid:

During the papermaking process, fine fibers, fillers (like calcium carbonate or clay), and sizing agents are suspended in water. Without effective retention aids, a significant portion of these valuable materials can be lost with the water that drains away, known as white water. PAM, when added to the pulp slurry, helps to aggregate these fines and fillers, causing them to attach more readily to the larger pulp fibers. This improved retention leads to:

  • Reduced loss of raw materials, translating to cost savings.
  • Enhanced opacity and brightness of the paper.
  • Improved formation of the paper sheet.

PAM as a Drainage Aid:

Efficient dewatering of the pulp slurry on the paper machine is critical for energy savings and increased production speed. PAM aids in drainage by bridging the suspended particles, creating larger flocs that allow water to pass through the forming paper web and drainage screens more quickly. This results in:

  • Faster drying times, leading to increased machine speed.
  • Reduced energy consumption in the drying section.
  • Improved dewatering performance of the pulp.

PAM as a Strength Enhancer:

PAM can also improve both the dry and wet strength of paper. By reinforcing the fiber network and improving the bonding between fibers and fillers, PAM contributes to stronger, more durable paper products. This is particularly beneficial for specialty papers or packaging grades that require enhanced physical properties.

Choosing the Right PAM for Papermaking:

The choice of PAM type and grade in papermaking depends on factors such as furnish composition, pH, and the specific paper machine conditions. Anionic PAM is often used for retention and drainage, while cationic PAM can be effective in deinking processes and for improving wet strength. As a leading anionic polyacrylamide supplier and a comprehensive PAM supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. offers a range of products to meet the diverse needs of the paper industry.
