Strong Base Anion Exchange Resin 201X7 FG is a premium-grade gel polystyrene resin crosslinked with divinylbenzene, specifically engineered for high-efficiency ion exchange processes. Featuring a quaternary ammonium functional group, this resin is optimized for the removal of strong acid anions and the production of high-purity water, ensuring exceptional chemical stability and consistent performance across demanding industrial environments.
Designed for versatility, 201X7 FG excels in pure water preparation, wastewater treatment, and the complex separation of rare elements in wet metallurgy. Its superior weight exchange capacity and precise particle size distribution make it an ideal alternative to global industry standards such as Amberlite IRA-400 and Diaion SA-10A, providing a cost-effective solution without compromising on technical precision.
| Polymer Structure | Gel polystyrene crosslinked with DVB | Ionic Form | Cl- |
|---|---|---|---|
| Functional Group | -N(CH3)3 | Appearance | White to pale yellow clear spherical beads |
| Weight Exchange Capacity | ≥3.5 mmol/g | Dry Volume Capacity | ≥1.35 mmol/ml |
| Bulk Density | 0.67 ~ 0.73 g/ml | Real Density | 1.07 ~ 1.10 g/ml |
| Water Retention | 42% ~ 48% | Particle Size Range | 0.315 ~ 1.25 mm (≥95%) |
Engineered to withstand maximum operating temperatures up to 100°C, ensuring reliability in high-heat industrial cycles.
High whole bead count (≥95%) and low uniformity coefficient (≤1.6) minimize resin attrition and pressure drops.
With a weight exchange capacity of ≥3.5mmol/g, it delivers higher throughput and fewer regeneration cycles.
Clear spherical beads with a strict size range ensure uniform flow and prevent channeling in the resin bed.
Effective for pure water production, wastewater polishing, and rare element separation in hydrometallurgy.
Fully compatible as a direct replacement for Amberlite IRA-400, AB-17, and Diaion SA-10A specifications.
Store in wet state above 0°C; use 5% salt water for long-term preservation to prevent dehydration.
Maintain operating velocities between 2-10 BV/h and ensure a filling height of 1-3m.
Utilize 2BV 3-5% HCl followed by 2BV 2-4% NaOH for efficient resin restoration.
Implement flocculation or sand filtration before the resin column to prevent suspended solid jamming.
Maintain a reasonable column diameter ratio to avoid bias current and ensure uniform liquid distribution.
Use wet packed columns or back-flushing to eliminate internal air bubbles for maximum efficiency.
| Performance Metric | Standard Resin | 201X7 FG Resin |
|---|---|---|
| Exchange Capacity | Low to Medium | High (≥3.5 mmol/g) |
| Operational Life | Standard | Extended (Low Attrition) |
| Regeneration Cost | Frequent | Reduced (High Efficiency) |
| Thermal Threshold | 60-80°C | Up to 100°C |
| Purity Output | Industrial Grade | High-Purity/Ultra-Pure |
It is primarily used for pure water preparation, wastewater treatment, wet metallurgy, and the separation of rare elements due to its strong anion exchange capabilities.
The resin should be kept in a wet state in a closed space. If unused for long periods, adding a 5% or higher salt water solution is recommended to prevent dehydration.
Regeneration is typically achieved using 2BV of 3-5% HCl followed by 2BV of 2-4% NaOH to restore the ionic form.
Yes, 201X7 FG is designed to meet the specifications of corresponding brands like Amberlite IRA-400, Amberlite AB-17, and Diaion SA-10A.
Steps such as sand-filtration or flocculation are required to remove suspended solids that could otherwise jam the resin pores and reduce efficiency.
The 201X7 FG resin can operate safely at temperatures up to 100°C, making it suitable for various high-temperature industrial processes.
