Anionic Polyacrylamide (APAM) is a versatile synthetic polymer extensively utilized across various industrial sectors for its powerful flocculation and water-solubilizing properties. As a specialized anionic polyacrylamide supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to producing APAM that meets rigorous quality standards and diverse application requirements. This article provides an overview of typical APAM specifications and its key industrial uses.

Key Specifications of Anionic Polyacrylamide:

The performance of APAM is largely dictated by its physical and chemical properties. Manufacturers typically offer APAM in various grades, differentiated by the following key parameters:

  • Appearance: APAM is typically supplied as a white to off-white granular powder or small beads. This form facilitates ease of handling and dissolution.
  • Molecular Weight: This is a critical parameter, often ranging from several million to over twenty million g/mol. Higher molecular weights generally lead to more effective flocculation and increased solution viscosity. For specific applications like oilfield EOR, tailored molecular weights are essential.
  • Ionic Degree (Degree of Hydrolysis): This refers to the percentage of acrylamide units that have been hydrolyzed to acrylate units, imparting the anionic charge. Ionic degrees can range from low (e.g., 10-20%) to high (e.g., 30-50%), influencing its interaction with different types of suspended solids.
  • Solid Content: Typically, APAM has a solid content of 88-90% or higher, ensuring a concentrated product that minimizes transportation and storage space.
  • Dissolution Time: The time required for the polymer to fully dissolve in water is an important operational factor. For most grades, this is generally under 1-1.5 hours with proper agitation, which we ensure through our manufacturing process.
  • Residual Monomer Content: Minimizing residual acrylamide monomer is crucial for safety and environmental reasons. Reputable manufacturers like us maintain very low residual monomer levels.

Major Industrial Applications:

The unique properties of APAM make it indispensable in several industries:

  • Water Treatment: APAM is a primary flocculant for raw water, industrial wastewater, and municipal sewage. It effectively clarifies water by aggregating suspended particles, aiding in sedimentation and filtration processes. Our role as a water treatment chemical manufacturer is exemplified by the quality of our APAM for these vital applications.
  • Oilfield Exploitation: In the oil and gas sector, APAM is used for Enhanced Oil Recovery (EOR) as a viscosity modifier for injection water. It also serves as a friction reducer and in drilling fluid formulations. Companies looking to purchase APAM flocculant rely on our consistent product for optimizing recovery.
  • Sludge Dewatering: APAM significantly improves the efficiency of sludge dewatering in wastewater treatment plants by promoting the formation of large, water-releasing flocs. This reduces sludge volume and handling costs.
  • Mining and Mineral Processing: APAM is used to aid in the separation of valuable minerals from waste materials, enhancing settling and filtration rates in tailings management and mineral flotation.
  • Papermaking: In the paper industry, APAM acts as a retention aid, improving the retention of fillers and fines, and as a strength enhancer for paper products.
