At NINGBO INNO PHARMCHEM CO.,LTD, we are committed to providing chemical solutions that drive innovation and efficiency across industries. The papermaking sector, in particular, benefits immensely from the specialized properties of Polyacrylamide (PAM) when utilized as a retention aid.

The papermaking process involves complex interactions between fibers, fillers, and chemical additives. Ensuring that these components are retained effectively within the paper web is crucial for both product quality and economic viability. This is where PAM, as a high-performance papermaking retention aid, plays a pivotal role. Its polymeric structure allows it to bridge and flocculate fine particles, such as cellulose fibers and mineral fillers, preventing them from escaping the forming paper sheet and entering the process water stream.

The effectiveness of PAM in this application stems from its ability to modify the colloidal properties of the pulp slurry. By adsorbing onto the surfaces of fibers and fillers, PAM alters their surface charge and creates inter-particle bridges. This aggregation process leads to improved drainage on the paper machine, faster sheet formation, and a more uniform distribution of components within the final paper product. Consequently, manufacturers can achieve enhanced paper strength, improved opacity, and better printability, all while reducing the loss of valuable materials.

Beyond its retention capabilities, PAM also contributes to improved water management within the paper mill. By promoting the settling of fines and fillers in the white water system, it facilitates cleaner process water, which can be recirculated more effectively. This not only conserves water resources but also reduces the load on effluent treatment systems. The precise selection of PAM type – whether anionic, cationic, or nonionic, and its specific molecular weight – is critical to achieving optimal results, depending on the unique furnish composition and machine conditions. For paper manufacturers looking to boost efficiency and product quality, incorporating advanced polyacrylamide solutions is a proven strategy.
