Strong Acid Cation Exchange Resin 001X7 FC is a premium-grade, gel-type copolymer synthesized from Styrene and Divinylbenzene (DVB). Featuring a sulfonic acid functional group, this high-performance resin is engineered for superior ion exchange efficiency, delivering exceptional stability and reliability across a wide range of industrial water treatment and metallurgical applications.
Designed for versatility, the 001X7 FC excels in water softening, pure water preparation, and the separation of rare elements in wet metallurgy. With a high exchange capacity and rigorous particle size uniformity, it ensures optimal flow rates and maximum purity, making it a direct and high-quality alternative to industry benchmarks such as Amberlite IRA-120, Dowex 50, and Diaion SK-IA.
| Polymer Structure | Styrene-DVB-Copolymer (Gel-type) | Functional Group | -SO3H (Sulfonic Acid) |
|---|---|---|---|
| Ionic Form | Na+ (Sodium Form) | Weight Exchange Capacity | ≥4.5 mmol/g |
| Volume Exchange Capacity | ≥1.9 mmol/ml | Real Density | 1.25 ~ 1.29 g/ml |
| Bulk Density | 0.77 ~ 0.87 g/ml | Water Retention | 45% ~ 50% |
| Particle Size Range | 0.45 ~ 1.25 mm (≥95%) | Uniformity Coefficient | ≤1.6 |
Robust Styrene-DVB structure ensures physical stability and resistance to osmotic shock during regeneration cycles.
High exchange capacity (≥4.5mmol/g) reduces regeneration frequency, lowering operational costs and downtime.
With a uniformity coefficient ≤1.6, it prevents channeling and ensures consistent pressure drops across the bed.
Safe operational window up to 120°C, allowing for high-temperature processing in specialized industrial environments.
Optimized for pure water preparation and rare element separation with minimal leakage and high selectivity.
Perfectly compatible as a replacement for Amberlite, Dowex, and Diaion strong acid cation resins.
Maintain resin in a wet state above 0°C to prevent bead cracking and degradation.
Use wet packing or back-flushing to eliminate air bubbles and ensure uniform flow.
Implement sand filtration or flocculation to prevent suspended solids from clogging pores.
Maintain column diameter ratios to avoid bias currents and ensure equal resin utilization.
Preserve in 5% salt water solution if unused to maintain stability and prevent agglomeration.
Follow a strict Alkali → Water → Acid → Water flow path for optimal ion exchange performance.
| Feature | Standard Resins | 001X7 FC Resin |
|---|---|---|
| Exchange Capacity | Average (3.8-4.2 mmol/g) | Superior (≥4.5 mmol/g) |
| Operating Temp | Up to 60-80°C | High Stability up to 120°C |
| Bead Uniformity | Variable | Strict (Coeff ≤1.6) |
| Regeneration Cost | Standard Cycle | Reduced via High Capacity |
| Service Life | Standard Industrial | Extended via DVB-Copolymer |
It is primarily used for water softening, producing ultrapure water, wet metallurgy processes, and the separation of rare elements from complex solutions.
The resin must be kept in a wet state. For long-term storage, it should be kept in a closed space or immersed in a salt solution of 5% or higher to prevent dehydration and agglomeration.
The recommended regeneration agents are 3-5% Hydrochloric Acid (HCl) and 2-4% Sodium Hydroxide (NaOH), applied at a velocity of 1-2 BV/h.
Yes, the 001X7 FC resin is designed to withstand maximum operating temperatures of up to 120°C.
Steps such as sand filtration or flocculation are essential to remove suspended solids, which would otherwise jam the resin pores and reduce exchange efficiency.
It is a high-performance equivalent to Amberlite IRA-120, Dowex 50, KY2-8, and Diaion SK-IA.
