The papermaking industry relies on a sophisticated interplay of chemicals and processes to transform raw materials into high-quality paper products. Among the essential chemical additives, Polyacrylamide (PAM) plays a crucial role, significantly impacting retention, drainage, and overall paper quality. NINGBO INNO PHARMCHEM CO.,LTD. provides specialized PAM solutions tailored for the unique demands of the papermaking sector.

In papermaking, PAM functions primarily as a retention and drainage aid. During the papermaking process, pulp slurry contains fine fibers, fillers (like calcium carbonate or clay), and other additives. Without effective aids, a significant portion of these valuable materials can be lost with the water during the sheet formation and dewatering stages. PAM, with its high molecular weight and ability to bridge particles, effectively binds these fine materials together. This bridging action, often combined with charge neutralization, creates larger flocs within the pulp slurry.

The benefits of using PAM in papermaking are substantial. Firstly, improved retention means that more fibers and fillers are kept within the paper sheet, leading to better paper strength, opacity, and smoothness. Secondly, enhanced drainage allows water to be removed more efficiently from the pulp. This speeds up the overall papermaking process, reduces energy consumption in drying, and can increase machine speeds. NINGBO INNO PHARMCHEM CO.,LTD. offers specific grades of polyacrylamide, including anionic and cationic types, that are optimized for these functions, ensuring superior performance in retention and drainage.

The selection of the appropriate type of PAM depends on the specific furnish conditions, such as pH and the charge characteristics of the other components in the pulp. Anionic PAM is often used as a retention aid for many paper grades, while cationic PAM can be particularly effective in improving drainage and retention, especially in systems with a neutral to alkaline pH. Understanding these nuances of polyacrylamide applications is key to maximizing efficiency and paper quality.

Furthermore, PAM can also function as a dry strength agent, improving the internal bonding of the paper sheet, and as a flocculant in the treatment of papermaking wastewater. By treating the wastewater, PAM helps to clarify the water, allowing for its reuse and reducing the environmental impact of the mill's operations. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing innovative polyacrylamide solutions that not only enhance paper production but also contribute to sustainable papermaking practices.
