|---|---|---|---|
| Weight Exchange Capacity | ≥3.7mmol/g | Volume Exchange Capacity | ≥1.2mmol/ml |
| Real Density | 1.06~1.10g/ml | Bulk Density | 0.65-0.73g/ml |
| Water Retention Capacity | 50-60 % | Particle Size Range | 0.45~1.25 mm (≥95%) |
| Uniformity Coefficient | ≤1.60 | Whole Bead Count | ≥95% |
Engineered to withstand maximum operating temperatures up to 120℃ without degrading structural integrity.
Strong mechanical strength and a high whole bead count (≥95%) minimize resin attrition over time.
Macroporous structure ensures high accessibility to active sites for efficient cyanide pulp adsorption.
Highly effective for desalination, hydrometallurgy, and specialized industrial water treatment.
A uniformity coefficient of ≤1.60 ensures balanced flow and prevents channeling in the resin bed.
Compatible with standard HCl and NaOH regeneration agents for rapid restoration of capacity.
Maintain resin in wet state with salt water (5%+) to ensure long-term stability.
Implement alkali-water-acid-water flow paths for optimal ion exchange efficiency.
Use flocculation and sand filtration to prevent suspended solids from jamming pores.
Anti-freezing precautions are mandatory during transport; keep storage above 0℃.
Allow sufficient headspace for resin expansion to prevent overflow during regeneration.
Utilize wet packing or back-flushing to eliminate internal air bubbles.
| Performance Metric | Standard Resin | D201 FC Resin |

It is primarily used for desalination and the adsorption of cyanide pulp in hydrometallurgy, as well as the removal of organic acids from aqueous solutions.
The resin should be kept in a wet state in a closed space, preferably with a salt water concentration of 5% or above, and stored above 0℃ to prevent freezing.
The resin is typically regenerated using 3-5% HCl (2BV) followed by 2-4% NaOH (2BV) to restore its ionic form and exchange capacity.
Flocculation or sand-filtration is required to remove suspended solids that could otherwise clog the macroporous structure, which would reduce the resin's efficiency.
Yes, D201 FC is designed as a high-performance equivalent to these brands, offering comparable or superior specifications for strong basic anion exchange.
The maximum recommended operating temperature for this specific resin is 120℃.
