Blufloc EA 6520 Oil-Based Anionic PAM Emulsion with High Anionic Degree
Product Introduction
EA 6520 is positioned for applications where very long polymer chains and high anionic character can aggregate fine mineral or coagulated industrial solids.
Because high molecular weight also makes the polymer sensitive to preparation and shear, the grade should be diluted, distributed, and mixed according to its TDS rather than treated as a simple liquid coagulant.
Blufloc EA 6520 is an oil-based anionic PAM emulsion with very high molecular weight and high anionic degree. It is designed for strong bridging in mining tailings, industrial clarification, coal washing, sand washing, and related solid-liquid separation.
Application Challenges
- Fine particles requiring long-chain bridging
- High solids throughput in continuous thickeners
- Need for rapid emulsion make-down
- Risk of chain damage from high-shear pumps or mixers
How the PAM Emulsion Works
EA 6520 adsorbs at multiple points and connects particles into larger floc. Its high anionic degree can support chain extension in suitable water chemistry, and its very-high molecular weight provides bridging reach. Actual performance depends on particle surface and dissolved ions.
Important: The suggested grades below are starting candidates, not a fixed prescription. Final selection and dosage require representative laboratory and plant trials.
Recommended Blufloc Grades
| Grade | Base | Molecular Weight | Charge | Suggested Screening Role |
|---|---|---|---|---|
| EA 6520 | Oil-based | Very High | High anionic | Mining, coal, sand, paper wastewater, and industrial clarification |
The product pages classify the cationic EC and EWC series as high molecular weight and the anionic EA and EWA grades as very high molecular weight. Exact commercial specification limits, active content, viscosity, shelf life, and preparation instructions should be confirmed on the current grade-specific TDS and order specification.
Product Advantages
- Very-high molecular weight
- High anionic degree
- Oil-based liquid emulsion
- Strong candidate for difficult fine-solids settling
- Factory-direct supply and application screening
Application Process
- Confirm that the make-down system is compatible with oil-based emulsion.
- Use clean dilution water and the grade-specific inversion sequence.
- Avoid neat-product contact with the process stream unless explicitly specified.
- Distribute rapidly, then reduce shear for floc growth.
- Optimize dose on active-mass and total-cost basis.
Product Selection Guidance
EA 6520 should be selected when tests show that high anionic degree and very-high molecular weight provide superior settling or capture. It should be compared with EWA 7520 when carrier preference or medium anionic charge may improve performance.
Compare candidates on active polymer mass and total operating cost. Neat-emulsion price per kilogram can be misleading if products differ in activity, preparation efficiency, dose, equipment throughput, cake or underflow quality, and downstream disposal cost.
Operating Indicators to Record
- Active polymer dose
- Floc size and strength
- Settling or drainage
- Water clarity
- Preparation consistency
Troubleshooting Note
If the product appears slow or inconsistent, inspect inversion water, mixing sequence, concentrated-solution viscosity, aging time, and pump calibration. High shear can reduce effective molecular weight and floc strength.
Packaging, Storage, and Safe Handling
Standard supply options shown on the Blufloc PAM emulsion product pages are 25 kg containers, 200 kg plastic drums, and 1000 kg IBCs. Keep the package sealed in a cool, dry, ventilated area and protect it from direct sunlight, freezing, and excessive heat. Follow the grade-specific TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills can make floors extremely slippery and should be contained and cleaned promptly.
