Polyacrylamide (PAM) is a linear water-soluble polymer with the chemical formula (C₃H₅NO)ₙ and CAS number 9003-05-8. This high-molecular-weight compound appears as a white or creamy white free-flowing powder. It is renowned for its exceptional flocculation, thickening, shear resistance, drag reduction, and dispersion properties. These characteristics make it an invaluable processing aid across numerous industries.
Product Specifications and Varieties
Polyacrylamide is available in several ionic types to suit different applications:
- Anionic Polyacrylamide: Features molecular weights ranging from 3 to 22 million and hydrolysis degrees between 10-40%. It is particularly effective in treating wastewater with positively charged particles.
- Cationic Polyacrylamide: Offers molecular weights between 5-12 million and variable cationicity from 5% to 80%. This type demonstrates superior performance with organic sludges from biological treatment processes.
- Non-ionic Polyacrylamide: Possesses molecular weights of 2-15 million with hydrolysis degrees below 5%. It works effectively across a broader pH range and with various suspended solids.
The solid content of all types typically exceeds 90%, with free monomer content maintained at 0.05% or lower to ensure safety and performance.
Key Applications and Uses
Water Treatment: Polyacrylamide serves as an efficient flocculating agent in both municipal and industrial wastewater treatment. It effectively removes suspended particles through charge neutralization and adsorption bridging mechanisms. Anionic PAM is suitable for steel, electroplating, metallurgy, and coal washing wastewater, while cationic PAM excels in treating organic sludges from biological processes.
Petroleum Industry: In oilfield applications, PAM functions as a driving agent for enhanced oil recovery, clay stabilizer, and fracturing fluid additive. It helps reduce friction阻力 and improves oil displacement efficiency.
Paper Manufacturing: PAM acts as a retention aid for fillers and pigments, paper strengthening agent, and sizing agent. It enhances paper quality and production efficiency while reducing environmental pollution.
Other Industries: Additional applications include soil conditioning, textile sizing, mineral processing, coal washing, and as a viscosity modifier in various industrial processes.
Usage Guidelines and Recommendations
For optimal results, dissolve PAM in clean water (neutral water for anionic/Non-ionic types, slightly acidic water for cationic types) at concentrations typically between 0.1%-0.3%. The dissolution process requires gradual sprinkling into water with gentle agitation to prevent lump formation.
Dissolution time varies from 30 minutes to several hours depending on product type and water temperature. Once prepared, use solutions promptly: within one day for cationic PAM and within two days for anionic PAM.
Safety and Handling Considerations
Polyacrylamide itself is considered nontoxic. However, appropriate precautions should be taken during handling to minimize dust generation. The product should be stored in a cool, dry, well-ventilated area, protected from moisture and direct sunlight. When stored properly, it maintains its effectiveness for up to two years.
