|---|---|---|---|
| Weight Exchange Capacity | ≥4.8 mmol/g | Volume Exchange Capacity | ≥1.45 mmol/ml |
| Real Density | 1.03~1.06 g/ml | Bulk Density | 0.65~0.72 g/ml |
| Water Retention Capacity | 48%~58% | Particle Size Range | 0.45~1.25 mm (≥95%) |
| Whole Bead Count | ≥95% | Uniformity Coefficient | ≤1.60 |
Strong structural integrity with a maximum operating temperature of 120℃, ensuring performance in extreme conditions.
High whole bead count (≥95%) reduces attrition and extends the replacement interval for industrial columns.
Exceptional weight exchange capacity (≥4.8mmol/g) allows for higher throughput and fewer regeneration cycles.
Strict particle size range (0.45-1.25mm) ensures optimal flow distribution and minimizes pressure drop.
Ideal for sugar decolorization, wastewater treatment, and refined organic matter separation.
Optimized for HCl and NaOH regeneration agents, streamlining maintenance and reducing downtime.
Ensure wet state preservation at temperatures above 0℃ to maintain resin activity.
Standard operation requires a precise Alkali-Water-Acid-Water flow sequence.
Implement flocculation and sand-filtration to prevent pore jamming by suspended solids.
Maintain reasonable column diameter ratios to avoid bias current and ensure uniform flow.
Anti-freezing measures are mandatory; avoid heavy stacking to prevent bead crushing.
Account for transformation expansion rates to prevent resin overflow during operation.
| Performance Metric | Standard Resin | D301 FC Resin |
|---|---|---|
| Exchange Capacity | Moderate | High (≥4.8 mmol/g) |
| Operational Temp | Up to 60-80℃ | Up to 120℃ |
| Regeneration Cost | High Frequency | Reduced Frequency |
| Bead Durability | Standard | Superior (≥95% Whole) |
| Organic Removal | Basic | Advanced Refinement |
D301 FC is primarily used for sugar decolorization, removal of refined organic matter, and industrial wastewater treatment where organic acid removal is required.
The resin should be kept in a closed space or immersed in a salt solution of 5% or higher to maintain its wet state and prevent dehydration.
Regeneration is typically achieved using 3-5% HCl (2BV) and 2-4% NaOH (2BV) to restore the resin's ion exchange capacity.
Yes, the D301 FC resin is designed to handle a maximum operating temperature of up to 120℃.
It is essential to implement pre-treatment steps such as flocculation, filtration, or sand-filtration before the liquid enters the resin column.
It is comparable in performance to industry standards such as Purolite A100, Dowex 66, and Amberlite IRA-93.
