|---|---|---|---|
| Ionic Form | Na+ | Weight Exchange Capacity | ≥4.35 mmol/g |
| Volume Exchange Capacity | ≥1.8 mmol/ml | Real Density | 1.25 ~ 1.28 g/ml |
| Bulk Density | 0.77 ~ 0.85 g/ml | Water Retention Capacity | 45% ~ 55% |
| Particle Size Range | 0.315 ~ 1.25 mm (≥95%) | Uniformity Coefficient | ≤1.6 |
Engineered to withstand maximum operating temperatures up to 100°C without compromising structural integrity.
Supports high operating velocities (2-10 BV/h), significantly increasing throughput for industrial water treatment.
With a whole bead count ≥95% and low color throw, it minimizes fines and ensures high-quality effluent.
Effective across multiple sectors including hydrometallurgy, catalysis, and ultra-pure water production.
Provides a weight exchange capacity of ≥4.35 mmol/g, reducing the frequency of regeneration cycles.
Direct functional equivalent to top global brands like Purolite and Amberlite for seamless replacement.
Must be kept in a wet state at temperatures above 0°C to prevent resin dehydration.
Standard regeneration using 3-5% HCl followed by 2-4% NaOH for optimal restoration.
Requires flocculation or sand-filtration to prevent suspended solids from jamming resin pores.
Recommended processing sequence: alkali → water → acid → water flow path.
Avoid placing heavy objects on the resin to prevent bead crushing and loss of capacity.
Set aside sufficient headspace to accommodate transformation expansion rates and prevent overflow.

D001 FG is primarily used for high-speed mixed bed water treatment, the recovery and recycling of precious metals from industrial streams, and as a catalyst in various organic chemical reactions.
The resin should be maintained in a wet state in a closed environment. For long-term storage, it is recommended to add a salt solution of 5% or higher to maintain stability and prevent dehydration.
The recommended regeneration process involves using 2BV of 3-5% HCl for desorption, followed by 2BV of 2-4% NaOH to restore the resin to its optimal state.
Yes, D001 FG is designed for high-temperature resilience, with a maximum operating temperature of up to 100°C, making it suitable for aggressive industrial processes.
Pre-treatment steps like sand-filtration or flocculation are essential to remove suspended solids. This prevents the macroporous structure of the resin from becoming jammed, which would otherwise decrease flow rates and capacity.
The macroporous structure allows for better diffusion of larger ions and provides higher physical and chemical stability compared to gel-type resins, especially in organic-rich or high-temperature solutions.
