Engineered to withstand temperatures up to 100°C, maintaining structural integrity under thermal stress.
Optimized operating velocities (2-10BV/h) ensure fast ion exchange and high throughput efficiency.
Ideal for preparing pure water and separating rare elements with minimal leakage and high precision.
A uniformity coefficient ≤1.4 and ≥95% whole bead count reduce pressure drops in the column.
Highly effective in water softening, hydrometallurgy, and advanced chemical synthesis processes.
Efficiently regenerated using 3-5% HCl or 2-4% NaOH, extending the resin's operational lifespan.
Maintain resin in wet state above 0°C to prevent dehydration and bead cracking.
Implement alkali-water-acid-water flow paths to maximize ion exchange efficiency.
Utilize flocculation and sand filtration before the column to prevent pore blockage.
Set aside sufficient freeboard space to prevent resin overflow during regeneration.
Preserve unused resin in 5% salt water within closed containers to ensure stability.
Avoid bias current by optimizing the column diameter ratio and using wet packing.
| Performance Metric | Standard Resins | 001X7 H MB Resin |
|---|---|---|
| Exchange Capacity | Moderate | High (≥1.75mmol/ml) |
| Thermal Stability | Up to 60-80°C | Up to 100°C |
| Bead Integrity | Average | High (≥95% Whole Beads) |
| Regeneration Cost | High Frequency | Low (Optimized Reagent Use) |
| Operational Life | Standard | Extended (Due to High DVB) |
Resin should be kept in a wet state, preferably in a closed container with a 5% or higher salt water solution, and stored at temperatures above 0°C to prevent freezing and degradation.
For optimal regeneration, use 2BV of 3-5% HCl (Hydrochloric Acid) or 2BV of 2-4% NaOH (Sodium Hydroxide), depending on the required ionic form.
It is critical to implement pre-treatment steps such as flocculation, filtration, or sand-filtration to remove suspended solids before the liquid enters the resin column.
A lower uniformity coefficient (≤1.4 for 001X7) indicates a more consistent particle size, which reduces pressure drops and prevents channeling within the resin bed.
Yes, the Strong Acid Cation Exchange Resin 001X7 H MB is specifically designed for wet metallurgy and the efficient separation of rare earth and other rare elements.
Ensure anti-freezing measures are in place during transit and avoid placing heavy objects on the resin packaging to prevent the beads from being crushed.
