The papermaking industry relies on a sophisticated array of chemical additives to produce high-quality paper products efficiently and sustainably. Among these, Polyacrylamide (PAM) plays a vital role, contributing significantly to improved retention, enhanced paper strength, and effective wastewater management. As a dedicated manufacturer and supplier of industrial chemicals, NINGBO INNO PHARMCHEM CO.,LTD. provides premium PAM solutions tailored for the unique demands of the paper industry.

PAM as a Retention Aid: Maximizing Fiber and Filler Efficiency

In the papermaking process, fine fibers, fillers (like clay or calcium carbonate), and sizing agents need to be retained within the paper sheet during formation. Without effective retention, these valuable materials are lost into the white water system, leading to:

  • Material Loss: Increased consumption of raw materials and higher production costs.
  • Environmental Impact: Increased solids load in wastewater, requiring more intensive treatment.
  • Reduced Paper Quality: Lower opacity, brightness, and strength in the final paper product.

PAM, particularly cationic PAM (CPAM) and certain amphoteric formulations, acts as an excellent retention aid. Its polymer chains bridge the gap between fine particles and fibers, creating larger agglomerates that are efficiently retained on the forming fabric. This not only improves the yield of valuable materials but also enhances the formation and quality of the paper. By partnering with us, paper manufacturers can purchase a consistent supply of high-performance PAM to optimize their retention efficiency.

Enhancing Paper Strength with PAM

Beyond retention, PAM can also function as a strength additive, improving both the dry and wet strength of paper. The polymer chains can bind to the cellulose fibers, reinforcing the inter-fiber hydrogen bonding network. This leads to:

  • Improved Tensile Strength: Resistance to pulling forces.
  • Enhanced Burst Strength: Resistance to pressure.
  • Increased Wet Strength: The ability of paper to maintain its integrity when wet, crucial for products like paper towels or packaging.

The specific grade of PAM used for strength enhancement is carefully selected based on the desired properties and the paper machine conditions. We are committed to providing paper mills with the technical expertise needed to select and apply the most effective PAM grades.

PAM for Papermaking Wastewater Treatment

The papermaking process generates significant volumes of wastewater, often containing suspended fibers, fillers, and organic materials. PAM is indispensable for treating this wastewater:

  • Clarification: PAM effectively flocculates suspended solids in white water and effluent streams, clarifying the water for recycling or safe discharge.
  • Sludge Dewatering: PAM significantly improves the dewatering of sludge generated from wastewater treatment processes, reducing its volume and disposal costs.

As a leading chemical supplier, we understand the critical importance of environmental compliance for the paper industry. Our PAM solutions are designed to meet these needs efficiently and cost-effectively.
