The paper industry relies on a sophisticated blend of raw materials and chemical additives to produce high-quality paper products efficiently. Among these, Polyaluminium Chloride (PAC) plays a multifaceted and vital role, acting not only as a vital sizing agent but also as an effective retention aid and effluent treatment chemical. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated supplier of specialty chemicals, highlights the significant contributions of PAC to modern paper manufacturing.

PAC as a Sizing Agent in Papermaking

Sizing is a critical process in papermaking that imparts resistance to liquid penetration, such as ink or water. Traditionally, rosin-alum systems were used, but these often presented issues with pH control and corrosion. Polyaluminium Chloride offers a superior alternative. As a chemical auxiliary agent, PAC works by hydrolyzing to form positively charged polymeric species that interact with anionic colloidal species (like rosin or synthetic sizing agents) and cellulose fibers. This interaction helps to fix the sizing agent onto the fiber surface, improving the paper's resistance to water and ink. When you buy PAC for this application, you are investing in enhanced paper quality and production efficiency.

Improving Retention and Drainage with PAC

Beyond sizing, PAC also functions as an effective retention aid and drainage enhancer. In the papermaking process, fine particles and fillers need to be retained within the paper sheet to maintain strength and opacity. PAC helps to aggregate these fines and fillers, promoting their retention on the wire. Simultaneously, it improves drainage – the rate at which water is removed from the pulp slurry. Faster drainage leads to increased machine speed and production output, a key benefit for paper mills sourcing their chemicals.

Effluent Treatment in the Paper Industry

The paper industry is also a significant consumer of water, and treating its wastewater is essential for environmental sustainability. PAC is highly effective in treating the effluent generated by paper mills. It efficiently removes suspended solids, color, and organic pollutants from the wastewater, helping mills meet discharge standards. As a supplier of water treatment chemicals, we recognize the dual benefit of PAC – improving product quality and facilitating environmental responsibility.
