The Strong Acid Cation Exchange Resin 001X7H FC is a high-performance, gel-type copolymer synthesized from styrene and divinylbenzene (DVB). Featuring a sulfonic acid functional group (-SO3H) in the H+ ionic form, this professional-grade resin is engineered for superior ion exchange capacity and exceptional chemical stability, making it an ideal solution for demanding industrial water treatment and metallurgical processes.
Designed for versatility and efficiency, the 001X7H FC is widely utilized in water softening, the production of high-purity water, and the precise separation of rare elements in wet metallurgy. With a high whole-bead count and optimized particle size distribution, it ensures minimal pressure drop and maximum operational efficiency across a wide range of industrial applications, serving as a high-quality alternative to global standards such as Amberlite IRA-120 and Dowex 50.
| Polymer Type | Styrene-DVB-Copolymer (Gel-type) | Functional Group | -SO3H |
|---|---|---|---|
| Ionic Form | H+ | Weight Exchange Capacity | ≥5.0 mmol/g |
| Volume Exchange Capacity | ≥1.75 mmol/ml | Real Density | 1.17 ~ 1.22 g/ml |
| Bulk Density | 0.73 ~ 0.83 g/ml | Water Retention Capacity | 51% ~ 56% |
| Particle Size Range | 0.45 ~ 1.25 mm (≥95%) | Whole Bead Count | ≥95% |
With a whole bead count of ≥95%, the resin resists fragmentation and maintains structural integrity under high-pressure flow.
Designed to operate reliably in demanding environments with a maximum operating temperature threshold of up to 100℃.
Boasts a high weight exchange capacity (≥5.0mmol/g), reducing the frequency of regeneration cycles and operational costs.
Optimized for rare element separation and wet metallurgy, ensuring high purity and precise ion selectivity.
Uniform particle size range (0.45-1.25mm) ensures smooth hydraulic flow and minimizes energy consumption during operation.
Fully compatible with standard industrial systems and serves as a direct replacement for Dowex 50 and Diaion SK-IA.
Maintain resins in a wet state above 0℃ to prevent dehydration and degradation of the polymer matrix.
For extended storage, use a closed environment or add a 5% salt solution to maintain bead stability.
Implement flocculation, filtration, or sand-filtration before liquid entry to prevent pore jamming.
Standard processing sequence: Alkali → Water → Acid → Water to ensure optimal ion exchange efficiency.
Maintain a reasonable column diameter ratio and use wet packing to eliminate internal bubbles.
Set aside adequate headspace to account for expansion rates during regeneration and prevent resin overflow.
| Performance Metric | Standard Cation Resin | 001X7H FC Resin |
|---|---|---|
| Exchange Capacity | Average (3.5-4.5 mmol/g) | High (≥5.0 mmol/g) |
| Bead Integrity | Variable (85-90% Whole) | Superior (≥95% Whole) |
| Temperature Limit | Typically 60-80℃ | Extended (Up to 100℃) |
| Regeneration Cycle | Frequent | Extended / Optimized |
| Operational ROI | Standard | High (Lower OPEX) |
It is primarily used for water softening, pure water preparation, wet metallurgy, and the separation of rare elements due to its strong acidity and high exchange capacity.
Resin must be kept in a wet state at temperatures above 0℃. For long-term storage, it should be kept in a closed space or preserved in a 5% or higher salt water solution.
The resin can be regenerated using 2BV of 3~5% HCl followed by 2BV of 2~4% NaOH, depending on the specific application requirements.
Pre-treatment steps like sand-filtration or flocculation are essential to remove suspended solids that could otherwise jam the resin pores and reduce efficiency.
Yes, 001X7H FC is designed to meet the technical specifications and performance benchmarks of corresponding brands like Amberlite IRA-120, Dowex 50, and Diaion SK-IA.
The 001X7H FC resin can withstand a maximum operating temperature of 100℃, providing stability for high-temperature industrial processes.
