The Strong Base Anion Exchange Resin 201X7 FC is a premium-grade, gel-type polystyrene resin crosslinked with divinylbenzene. Specifically engineered for high-efficiency ion exchange, it features quaternary ammonium functional groups in the chloride form, ensuring exceptional performance in removing anions from aqueous solutions with high precision and reliability.
Designed for versatility and durability, this resin is the ideal solution for pure water preparation, industrial wastewater treatment, and the separation of rare elements in wet metallurgy. Its robust physical structure and high exchange capacity make it a compatible high-performance alternative to industry standards such as Amberlite IRA-400, Amberlite AB-17, and Diaion SA-10A.
| Appearance | White to pale yellow clear spherical beads | Polymer Structure | Gel polystyrene crosslinked with DVB |
|---|---|---|---|
| Functional Group | -N(CH3)3 | Ionic Form (Shipped) | Cl- |
| 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 | 0.45~1.25 mm (≥95%) |
Optimized for pure water preparation, effectively removing dissolved solids and contaminants.
Capable of maintaining operational integrity at maximum operating temperatures up to 100℃.
Weight exchange capacity of ≥3.5mmol/g ensures longer cycles and fewer regenerations.
Low uniformity coefficient (≤1.6) prevents bias current and optimizes fluid flow.
Highly effective for rare element separation and specialized wet metallurgy applications.
Direct replacement for Amberlite and Diaion series with equivalent or superior performance.
Maintain resin in wet state and store above 0℃ to prevent degradation.
Maintain operating velocity between 2-10 BV/h for maximum efficiency.
Systematic regeneration using 3-5% HCl and 2-4% NaOH solutions.
Implement sand-filtration or flocculation to prevent pore jamming.
Set aside sufficient freeboard space to prevent resin overflow during expansion.
Regular backwashing to loosen resin layers during long-term storage.
| Performance Metric | Standard Anion Resin | 201X7 FC Resin |
|---|---|---|
| Exchange Capacity | Moderate | High (≥3.5mmol/g) |
| Thermal Limit | 60-80℃ | Up to 100℃ |
| Operational Life | Standard | Extended (High Durability) |
| Regeneration Cost | Higher Frequency | Reduced Frequency |
| Purity Output | Standard Pure Water | Ultra-Pure Grade |
It is primarily used for pure water preparation, industrial wastewater treatment, and the separation of rare elements in wet metallurgy applications.
Resin should be kept in a wet state above 0℃. For long-term storage, it should be kept in a closed space or preserved in a salt solution of 5% or higher.
The recommended regeneration process involves using 2BV of 3-5% HCl followed by 2BV of 2-4% NaOH.
Yes, 201X7 FC is designed as a high-performance corresponding brand equivalent to Amberlite IRA-400, AB-17, and Diaion SA-10A.
It is essential to implement pre-treatment steps such as flocculation, filtration, or sand-filtration before the liquid enters the resin column to remove suspended solids.
The maximum operating temperature for this resin is 100℃, providing excellent stability for high-temperature industrial processes.
