The Strong Acid Cation Exchange Resin D001 SC is a high-performance, macroporous styrene-divinylbenzene copolymer resin engineered for superior efficiency in demanding industrial environments. Featuring a sulfonic acid functional group in Na+ ionic form, this resin is specifically designed to provide exceptional exchange capacity and stability for water treatment and chemical processing applications.
Optimized for versatility, the D001 SC excels in high-speed mixed bed water treatment, precious metal recovery, and organic catalysis. Its robust macroporous structure ensures high mechanical strength and excellent osmotic shock resistance, making it a reliable alternative to industry standards such as Amberlite 200, Lewatit Sp-210, and Purolite C150.
| Polymer Structure | Styrene-DVB-Copolymer (Macroporous) | Functional Group | Sulfuric Acid |
|---|---|---|---|
| Ionic Form | Na+ | Appearance | White to light yellow opaque spherical beads |
| 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 | 45%~55% | Particle Size Range | 0.63~1.25 mm (≥95%) |
High whole bead count (≥95%) ensures minimal attrition and long-term structural integrity during operation.
Capable of maintaining optimal performance at maximum operating temperatures up to 120℃.
Exceptional weight exchange capacity (≥4.35mmol/g) for maximized ion removal and productivity.
Optimized for high-speed mixed bed treatment with operating velocities from 2 to 10 BV/h.
Strict uniformity coefficient (≤1.4) prevents channeling and ensures consistent liquid flow distribution.
Perfectly interchangeable with major brands like Purolite and Lewatit for seamless system integration.
Store in wet state above 0℃ in closed spaces or with 5% salt water to prevent dehydration.
Efficient desorption using 3-5% HCl (2BV) followed by 2-4% NaOH (2BV) for renewal.
Implement flocculation or sand-filtration to prevent suspended solids from jamming resin pores.
Standard processing sequence: Alkali → Water → Acid → Water for optimal ion exchange.
Maintain reasonable diameter ratios to avoid bias current and use wet packing to remove bubbles.
Calculate transformation expansion rates to set appropriate freeboard space and prevent overflow.
| Performance Metric | Standard Resin | D001 SC Resin | Benefit Index |
|---|---|---|---|
| Exchange Capacity | 3.2 - 3.8 mmol/g | ≥4.35 mmol/g | +15-20% Efficiency |
| Operational Temp | Up to 60-80℃ | Up to 120℃ | Extreme Stability |
| Bead Integrity | 85-90% Whole | ≥95% Whole | Lower Replacement Rate |
| Process Velocity | 1-5 BV/h | 2-10 BV/h | Faster Cycle Time |
| Life Cycle Cost | Baseline | Reduced OpEx | High ROI |
It is primarily used in high-speed mixed bed water treatment, the recycling of precious metals, and as a catalyst in various organic catalysis processes.
Resin must be kept in a wet state. For long-term storage, place it in a closed container with 5% salt water and ensure temperatures remain above 0℃ to prevent freezing.
Regeneration typically requires 2BV of 3-5% Hydrochloric Acid (HCl) followed by 2BV of 2-4% Sodium Hydroxide (NaOH).
Yes, the D001 SC is designed to handle maximum operating temperatures up to 120℃, providing stability where standard resins might fail.
We strongly recommend using pre-treatment steps such as flocculation, filtration, or sand-filtration to remove suspended solids before the liquid enters the resin column.
Macroporous resins like D001 SC have a permanent pore structure, offering better physical stability and the ability to handle larger molecules compared to gel-type resins.
