NINGBO INNO PHARMCHEM CO.,LTD. recognizes the critical demands of the papermaking industry for efficiency, quality, and environmental sustainability. Our high molecular weight Anionic Polyacrylamide (APAM) is a sophisticated chemical solution engineered to meet these challenges head-on. In the fast-paced world of paper production, precise control over fiber and filler retention, drainage, and overall paper strength is paramount, and APAM delivers exceptional performance in these areas.

The papermaking process involves a complex slurry of fibers, fillers (such as clay or calcium carbonate), and other additives suspended in water. Efficiently retaining these fine particles within the paper web while allowing water to drain rapidly is a key challenge. APAM acts as a powerful retention and drainage aid. Its long, anionic polymer chains bridge the gap between fine particles, including cellulose fibers and mineral fillers, forming larger, more robust flocs. This improved flocculation enhances the retention of these valuable components within the forming paper sheet, minimizing their loss into the white water system. This not only leads to higher material utilization but also reduces the solids load in the wastewater, easing the burden on effluent treatment.

Beyond retention, APAM significantly improves drainage rates. As water is removed from the forming paper web through screens and vacuum systems, APAM-induced flocs create larger voids within the sheet structure. This increased porosity allows water to escape more easily, accelerating the dewatering process. Faster drainage means higher machine speeds, increased production output, and potentially reduced energy consumption in the drying sections of the paper machine. The efficiency of APAM as a papermaking additive directly translates into tangible economic benefits for manufacturers.

Furthermore, APAM contributes to the overall quality and strength of the finished paper. By promoting better integration of fibers and fillers, it can enhance dry strength properties like tensile strength and burst strength. In certain applications, it can also function as a sizing agent, improving the paper's resistance to water penetration, which is crucial for printability and durability. The ability of APAM to form dense films with fibers also contributes to finer water-proofing characteristics, extending the shelf life and usability of the paper products.

The effectiveness of APAM can be further optimized when used in conjunction with other papermaking chemicals, such as cationic coagulants. This synergistic approach, leveraging the different charge characteristics of polymers, can lead to even more pronounced improvements in retention, drainage, and effluent clarity. NINGBO INNO PHARMCHEM CO.,LTD. offers expert technical support to help clients tailor the application of APAM to their specific machine conditions and furnish compositions, ensuring optimal performance and cost-effectiveness.
