The papermaking industry relies on a sophisticated array of chemicals to transform raw pulp into high-quality paper products. Among these essential chemicals, Polyaluminum Chloride (PAC) plays a multifaceted role, acting as a crucial agent that enhances both product quality and process efficiency. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of PAC solutions that are instrumental to modern papermaking operations.

In papermaking, PAC is primarily utilized as a coagulant and flocculant. During the pulping and paper formation stages, various additives and fine particles are introduced to the pulp slurry. PAC helps to efficiently bind these components together, improving the retention of fillers and fibers on the forming fabric. This leads to a more uniform sheet structure, reduced material loss, and ultimately, better paper quality, including improved strength and brightness.

Furthermore, PAC serves as an effective precipitant for improving water clarification within the papermaking process. Closed-loop water systems are common in paper mills to conserve water and reduce effluent. However, these systems can accumulate fines and dissolved substances that affect water clarity and machine runnability. PAC helps to remove these impurities, ensuring that the process water remains clean and efficient. This also contributes to reduced load on wastewater treatment facilities.

Another significant application of PAC in the paper industry is its use as a sizing agent or a component in sizing formulations. Sizing agents control the paper's absorbency, preventing ink feathering and improving printability. PAC's chemical properties allow it to interact with cellulose fibers and sizing agents, enhancing the overall sizing efficiency and performance of the final paper product.

NINGBO INNO PHARMCHEM CO.,LTD. understands the specific demands of the papermaking sector and provides PAC that is optimized for these applications. Their commitment to delivering consistent quality ensures that paper manufacturers can rely on their PAC products to achieve superior paper quality, optimize resource usage, and maintain efficient production cycles. The strategic use of PAC by NINGBO INNO PHARMCHEM CO.,LTD. contributes significantly to the innovation and sustainability of the global paper industry.
