Polyacrylamide (PAM) is a highly versatile synthetic polymer with extensive applications across numerous industries. For procurement managers, research scientists, and formulators, understanding its properties, types, and applications is crucial for making informed purchasing decisions. This guide from NINGBO INNO PHARMCHEM CO.,LTD., a leading polyacrylamide manufacturer in China, provides a comprehensive overview of PAM.

What is Polyacrylamide (PAM)?

PAM is a water-soluble polymer formed from acrylamide monomers. Its high molecular weight and chain structure give it unique properties, primarily as a flocculant, thickener, and suspending agent. PAM's primary function is to facilitate the aggregation of small particles into larger, more manageable clumps (flocs), which aids significantly in solid-liquid separation processes. Its chemical structure can be modified to yield different ionic characteristics: anionic, cationic, and nonionic.

Key Types and Their Properties:

  • Anionic Polyacrylamide (APAM): Carries a negative charge. Ideal for treating water with positively charged suspended solids (e.g., clay, metal oxides). Commonly used in wastewater treatment, mining, and coal washing. As a polyacrylamide manufacturer in China, we offer various grades of APAM to suit diverse needs.
  • Cationic Polyacrylamide (CPAM): Carries a positive charge. Effective for removing negatively charged contaminants like organic matter, dyes, and oils. Widely used in sludge dewatering, municipal wastewater treatment, and the paper industry. Sourcing reliable cationic polyacrylamide supplier China is key for efficient sludge management.
  • Nonionic Polyacrylamide (NPAM): Has no net charge. Useful in applications requiring minimal ionic interaction or in specific water conditions. It aids in flocculation through bridging mechanisms.

Major Industrial Applications:

  • Water Treatment: PAM is indispensable for clarifying drinking water, treating municipal sewage, and purifying industrial wastewater by removing turbidity and suspended solids.
  • Papermaking: Used as a retention aid, drainage aid, and strength agent to improve paper quality and process efficiency. We provide specific grades of nonionic polyacrylamide for paper industry.
  • Mining and Mineral Processing: PAM enhances solid-liquid separation in processes like tailings thickening, red mud settling, and mineral recovery.
  • Sludge Dewatering: High molecular weight PAM is particularly effective in reducing sludge volume, lowering disposal costs and improving handling. This is where high molecular weight PAM for sludge dewatering proves its value.
  • Oil and Gas: PAM is used in enhanced oil recovery (EOR) as a viscosity modifier and friction reducer in hydraulic fracturing fluids.

Purchasing Considerations:

  • Product Type and Grade: Select PAM based on the specific application, water chemistry, and contaminant characteristics.
  • Molecular Weight: Higher molecular weights generally offer better flocculation and thickening properties, especially for sludge dewatering.
  • Ionic Charge and Degree: Match the PAM's charge to the contaminants for optimal performance.
  • Purity and Quality: Ensure the product meets industry standards for purity, especially for drinking water applications.
  • Supplier Reliability: Partnering with a reputable polyacrylamide manufacturer in China like NINGBO INNO PHARMCHEM CO.,LTD. ensures consistent quality, competitive pricing, and dependable supply. We offer favorable polyacrylamide price for wastewater treatment and other industrial uses.
