Polydadmac: A Cornerstone in Modern Chemical Applications for Superior Water Treatment and Beyond

Polydiallyldimethylammonium Chloride, commonly known as PolyDADMAC or PDADMAC, stands as a highly effective and versatile cationic polymer with extensive applications across numerous industries. Produced by NINGBO INNO PHARMCHEM CO.,LTD., this water-soluble macromolecule is instrumental in processes requiring efficient charge neutralization, flocculation, and coagulation. Available in both liquid and powder forms, PolyDADMAC offers robust solutions for critical challenges, particularly in environmental and industrial settings.

Chemically, PolyDADMAC (CAS No. 26062-79-3) is a homopolymer of diallyldimethylammonium chloride (DADMAC), characterized by its strong cationic charge density. This inherent positive charge allows it to effectively interact with and neutralize negatively charged colloidal materials and suspended solids present in various aqueous systems. With a molecular formula of (C8H16NCl)n, its molecular weight typically ranges from hundreds of thousands to a million grams per mole, contributing to its diverse performance capabilities. PolyDADMAC exhibits excellent stability across a wide pH range, generally effective from pH 4 to 10, or even 0.5 to 14 depending on the specific application, and is known for being unhydrolyzed, non-flammable, and possessing low toxicity, making it a safe and reliable choice for numerous uses.

The primary and most impactful application of PolyDADMAC is in water treatment. It serves as a superior coagulant and flocculant for purifying both industrial wastewater and surface water, as well as crucial in drinking water clarification processes. Its high activity accelerates the sedimentation rate of impurities, significantly improving water clarity even at relatively low doses. PolyDADMAC is highly effective in reducing turbidity, removing natural organic matter such as humic and fulvic acids, and aiding in the removal of algae, bacteria, and viruses. Furthermore, in wastewater treatment, it plays a vital role in sludge thickening and dewatering, leading to reduced sludge volume and improved management efficiency compared to traditional inorganic coagulants.

Beyond water purification, PolyDADMAC from NINGBO INNO PHARMCHEM CO.,LTD. finds critical roles in several other sectors. In the pulp and paper industry, it is used for controlling disturbing substances, enhancing retention and dewatering in paper production, providing superior fixing of pitch and latex, and improving the efficiency of disk filters and flotators. For the textile industry, it acts as an advanced formaldehyde-free color-fixing agent, improving fabric color fastness and imparting a desirable stiffness. The oil field industry leverages PolyDADMAC as a clay stabilizer, an acid fracturing cationic additive, a mud treatment agent, an oily wastewater treatment solution, a scale inhibitor, and an additive in acidizing and plugging fluids. Additionally, its properties extend to the personal care and daily chemical industries, where it functions as a shampoo carding agent, wetting agent, and antistatic agent.

For optimal performance, PolyDADMAC, especially in its liquid form, should typically be diluted to a concentration of 0.5%-0.05% (based on solid content) when used alone. The precise dosage depends on the turbidity and concentration of the water or wastewater being treated, with the most economical dosage often determined through jar tests. Continuous dosing and careful consideration of the dosing spot and mixing velocity are recommended to ensure even distribution and effective floc formation. Powdered PolyDADMAC requires preparation in facilities equipped with appropriate dosing and distribution devices, with sustained moderate stirring and controlled water temperature (10-40°C) being essential. Both forms should be sealed and stored in a cool, dry, and dark place, with the powder form requiring protection from dampness to maintain its efficacy over its one-year shelf life.
