With three decades of experience in the chemical industry, we stand as a professional supplier specializing in the import and export of polyacrylamide (PAM). Known globally as the "Industrial Auxiliary Agent," this versatile polymer plays a critical role across numerous sectors. In international markets, our polyacrylamide is extensively used in water treatment, papermaking, mining, and metallurgy. Domestically, while the oil extraction industry remains the largest consumer, the fastest-growing demand now comes from water treatment and papermaking applications.
What Is Polyacrylamide?
Polyacrylamide, commonly abbreviated as PAM, appears as a white powder or fine granular material. It is a generic term for polymers obtained by the polymerization of acrylamide monomers or through copolymerization with other monomers. As one of the most widely applied water-soluble polymers, PAM is classified into four types based on ionic character: non-ionic, anionic, cationic, and amphoteric. This diversity allows it to meet the specific processing requirements of different industries.
Key Applications Across Industries
1. Water Treatment: As a high-performance flocculant, PAM is essential for solid-liquid separation in municipal sewage treatment and industrial effluent treatment . It effectively aggregates suspended particles, improving water clarity and enabling efficient sludge dewatering .
2. Oil & Gas Industry: In enhanced oil recovery (EOR), PAM serves as a polymer flooding agent to increase water viscosity, improve sweep efficiency, and boost crude oil production . It is also used as a drilling mud additive to stabilize wells and as a friction reducer .
3. Papermaking: PAM functions as a retention aid, drainage aid, and strengthening agent . It improves paper quality by enhancing dry and wet strength while reducing fiber and filler loss during production .
4. Mining & Mineral Processing: In mineral processing and coal washing, PAM facilitates rapid settling of suspended solids, improving equipment efficiency and enabling water recycling .
5. Other Industrial Uses: PAM is also applied in textile sizing, sugar refining clarification, and even as a soil conditioner in agriculture to prevent erosion and improve water infiltration .
Product Forms and Selection
Polyacrylamide is available in both powder and emulsion forms, with molecular weights adjustable from millions to over twenty million to suit different application needs . Selecting the right ionic type and molecular weight is crucial for optimal performance:
- Anionic PAM is ideal for neutral or alkaline wastewater with coarse, positively charged suspended particles .
- Cationic PAM works best for organic sludges and negatively charged suspensions, commonly found in municipal and food processing waste .
- Non-ionic PAM suits mixed inorganic-organic suspensions in acidic or neutral conditions .
Handling and Storage Guidelines
To achieve maximum efficiency, PAM should be dissolved in clean water at recommended concentrations (typically 0.1%-0.5%) using proper agitation to prevent "fish eye" clumps . The product is hygroscopic and should be stored in a cool, dry place below 35°C, away from moisture and direct sunlight .
