The Strong Acid Cation Exchange Resin 001×8 FG is a high-performance, gel-type copolymer of styrene and divinylbenzene (DVB) with sulfonic acid functional groups. Specifically engineered for industrial-grade ion exchange, this resin is supplied in the Na+ ionic form, offering exceptional efficiency in the removal of cations and the purification of water and chemical solutions.
Designed for versatility and durability, it excels in a wide array of demanding applications, including water softening, the production of high-purity water, wet metallurgy, and the precise separation of rare elements. With a robust structure and optimized exchange capacity, it serves as a professional-grade alternative to industry standards such as Amberlite IRA-120, Dowex 50, and Diaion SK-IA.
| Appearance | White to pale yellow clear spherical beads | Polymer | Styrene-DVB-Copolymer, gel-type |
|---|---|---|---|
| Functional Group | -SO3H | Ionic Form | Na+ |
| Weight Exchange Capacity | ≥4.5 mmol/g | Volume Exchange Capacity | ≥2.0 mmol/ml |
| Real Density | 1.26~1.30 g/ml | Bulk Density | 0.78~0.88 g/ml |
| Water Retention Capacity | 43%~48% | Particle Size Range | 0.315~1.25 mm (≥95%) |
Low color throw (≤25 APHA) ensures minimal contamination, making it ideal for pure water preparation.
Supports a maximum operating temperature of up to 100℃, allowing for high-temperature industrial processes.
High volume exchange capacity (≥2.0 mmol/ml) reduces regeneration frequency and operational costs.
Strict uniformity coefficient (≤1.6) prevents channeling and ensures consistent flow distribution.
High whole bead count (≥95%) prevents resin breakdown and column clogging over time.
Seamlessly compatible with standard regeneration agents including HCl and NaOH for efficient recovery.
Maintain resin in a wet state, preferably above 0℃, to preserve bead structure and activity.
Use closed containers or a 5% salt water solution for long-term storage to prevent dehydration.
Implement flocculation and filtration before the resin column to prevent pore jamming by solids.
Allow sufficient freeboard space based on expansion rates to prevent resin overflow during backwash.
Adhere to the Alkali-Water-Acid-Water flow path for optimal processing efficiency.
Utilize wet packing or back-flushing techniques to eliminate air bubbles within the resin layer.
| Metric | Standard Resin | 001×8 FG Premium |
|---|---|---|
| Cycle Life | Moderate | Extended High-Cycle |
| Regen. Cost | Higher Frequency | Low (High Capacity) |
| Water Purity | Standard | Ultra-Pure / Low Color |
| Op. Temp | Up to 60℃ | Up to 100℃ |
| ROI Period | Standard | Accelerated (Lower OpEx) |
It is primarily used for water softening, preparation of pure water, wet metallurgy, and the separation of rare elements from chemical solutions.
Resin should be stored in a closed space, kept wet, and preserved in a 5% or higher salt water solution to maintain its properties.
The recommended regeneration agents are 3~5% HCl (Hydrochloric Acid) and 2~4% NaOH (Sodium Hydroxide).
Pre-filtration or sand-filtration is required to remove suspended solids that could otherwise jam the resin pores and reduce exchange efficiency.
Yes, this specific resin is designed to handle maximum operating temperatures up to 100℃.
You must account for the resin's transformation expansion rate when designing the column height, leaving enough headspace to prevent overflow.
