In the intricate world of papermaking, achieving optimal efficiency, superior product quality, and minimized environmental impact requires precise chemical control. Polyacrylamide (PAM) flocculants are widely recognized for their significant contributions to the papermaking process, acting as retention aids, drainage aids, and strength enhancers. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, provides high-quality PAM solutions that are vital for modern paper mills.

Enhancing Retention and Drainage:

Effective retention and drainage are fundamental to efficient papermaking. PAM plays a crucial role in:

  • Improving Retention of Fines and Fillers: PAM helps to agglomerate fine fibers, fillers (like calcium carbonate or clay), and pigments, preventing them from passing through the forming fabric with the water. This increases the retention rate, leading to better material utilization and reduced raw material costs.
  • Accelerating Drainage: By forming larger, more porous flocs, PAM promotes faster dewatering of the paper web on the paper machine. This allows for higher machine speeds and increased production output, while also reducing the energy required for drying.
  • Reducing White Water Contamination: Enhanced retention means less fine material and filler enters the white water system, leading to clearer white water, reduced pollutant load, and improved recirculating water quality.

Boosting Paper Quality and Strength:

Beyond process efficiency, PAM contributes directly to the quality and strength of the finished paper product:

  • Dry Strength Enhancement: Certain types of PAM can improve the internal bonding between paper fibers, increasing the tensile strength, burst strength, and stiffness of the paper.
  • Wet Strength Improvement: Specialized PAM formulations can also enhance the paper's ability to retain its strength when wet, crucial for applications like paper towels, tissues, and packaging.
  • Improved Surface Properties: PAM can contribute to smoother paper surfaces and better printability by influencing the distribution of fillers and fines.

Choosing the Right Polyacrylamide for Papermaking:

The papermaking process often involves a complex interplay of fibers, fillers, and water chemistry. Typically, cationic and anionic PAM are used, often in combination, to achieve optimal results. Cationic PAM is frequently used as a retention and drainage aid, while anionic PAM can be effective in specific applications, such as sludge dewatering from wastewater treatment within the mill. The choice depends on the furnish composition, pH, and other additives used. Jar testing and consultation with experienced suppliers are essential to determine the most effective PAM type and dosage.
