Featuring a sulfonic acid functional group, this high-capacity resin is optimized for rigorous industrial applications, offering exceptional stability and a consistent spherical bead morphology for streamlined flow and maximum throughput.
Designed for versatility, this resin excels in critical water treatment and metallurgical processes. Whether utilized for industrial water softening, the production of high-purity water, or the precise separation of rare elements in wet metallurgy, 001×7 FG provides a reliable, high-performance solution that meets international standards, making it a direct high-quality alternative to industry benchmarks like Amberlite IRA-120 and Dowex 50.
| Polymer Structure | Styrene-DVB Copolymer (Gel-type) | Functional Group | -SO3H (Sulfonic Acid) |
|---|---|---|---|
| Ionic Form | Na+ (Sodium) | 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 | 0.315 ~ 1.25 mm (≥95%) | Uniformity Coefficient | ≤ 1.6 |
Robust styrene-DVB structure ensures longevity and resistance to degradation under harsh chemical conditions.
High weight and volume exchange capacities maximize ion capture and extend regeneration cycles.
Low uniformity coefficient (≤1.6) reduces pressure drop and prevents premature breakthrough.
Operates efficiently at maximum temperatures up to 120°C, suitable for high-heat industrial loops.
Strict size range (0.315-1.25mm) ensures optimal liquid distribution and minimal void space.
Versatile application from pure water preparation to rare element separation in metallurgy.
Maintain in wet state above 0°C; use 5% salt water for long-term preservation to prevent drying.
Maintain operating velocity between 2-10BV/h to ensure maximum exchange efficiency.
Implement sand filtration or flocculation to prevent suspended solids from jamming resin pores.
Standardized regeneration using 3-5% HCl and 2-4% NaOH for optimal capacity recovery.
Strict anti-freezing transport and prevention of heavy stacking to avoid bead crushing.
Use wet packed columns and maintain reasonable diameter ratios to avoid bias current.
| Performance Metric | Standard Grade Resin | 001×7 FG Premium |
|---|---|---|
| Exchange Capacity | Average Capacity | High (≥ 1.9 mmol/ml) |
| Operating Life | Standard Lifespan | Extended via DVB-Copolymer |
| Pressure Drop | Variable / High | Low & Consistent (Uniform) |
| Regeneration Cost | Higher Chemical Usage | Optimized (2-5% Concentration) |
| Purity Output | Industrial Grade | High Purity / Rare Element Grade |
It is primarily used for water softening, pure water preparation, wet metallurgy, and the separation of rare elements by exchanging cations with hydrogen or sodium ions.
Resin must be kept in a wet state above 0°C. For long-term storage, it should be kept in a closed space or immersed in a 5% or higher salt water solution.
Typical regeneration is achieved using 3-5% Hydrochloric Acid (HCl) and 2-4% Sodium Hydroxide (NaOH) at a velocity of 1-2 BV/h.
Steps like flocculation or sand-filtration are required to remove suspended solids, which otherwise would jam the resin pores and reduce exchange efficiency.
Yes, the 001×7 FG is designed to withstand maximum operating temperatures of up to 120°C.
Bias current occurs when liquid flows unevenly through the resin bed. Ensuring a reasonable column diameter ratio prevents this, ensuring all resin beads are utilized equally.
