The papermaking industry is constantly seeking ways to improve efficiency, product quality, and environmental sustainability. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize Polyacrylamide (PAM) as a pivotal chemical additive that addresses these very needs within the papermaking process. PAM's unique properties as a polymer flocculant and functional additive make it invaluable for enhancing fiber retention, improving drainage, and contributing to a more sustainable manufacturing cycle.

In the intricate process of papermaking, maintaining fine fibers and fillers within the paper sheet is crucial for both the quality of the final product and the economic viability of the operation. This is where PAM, particularly anionic and cationic types, plays a significant role as a retention aid. By bridging the gap between fibers and fillers, PAM causes them to aggregate, preventing their loss into the white water system. This leads to higher material utilization, reduced waste, and improved opacity and smoothness of the paper. For instance, anionic polyacrylamide for papermaking is often favored for its strong bridging capabilities with positively charged fibers and additives.

Beyond retention, PAM functions as a highly effective drainage aid. During the papermaking process, rapid removal of water from the pulp slurry is essential for increasing production speeds and reducing energy consumption in drying stages. PAM helps to flocculate the fibers, creating a more open structure that allows water to drain more freely. This improved drainage not only boosts machine speed but also results in a more uniform sheet formation and better dewatering of the resulting paper web.

Furthermore, PAM contributes to the overall strength of the paper. By promoting better fiber bonding and retention, it enhances both the dry and wet strength of the paper. This means the paper is more durable, resists tearing, and maintains its integrity even when exposed to moisture, which is critical for various paper applications, from packaging to printing.

The application of PAM in papermaking also addresses environmental concerns. By improving the efficiency of fiber and filler retention, it reduces the amount of fine materials discharged into the wastewater. This minimizes the organic load on effluent treatment systems and reduces the need for extensive water purification. The use of PAM can, therefore, lead to a lower environmental footprint for paper mills.

At NINGBO INNO PHARMCHEM CO.,LTD., we offer a range of specialized PAM products tailored for the papermaking industry. Understanding the specific needs of each mill—whether it's improving retention of fine particles, accelerating drainage, or enhancing paper strength—allows us to recommend the most effective PAM grade. The correct selection and application of polyacrylamide in papermaking can lead to significant improvements in product quality, process efficiency, and environmental performance, making it a key component in modern, sustainable paper manufacturing.
