D201 Type I Strong Base Anion Exchange Resin
The D201 Type I Strong Base Anion Exchange Resin is a premium gel-type polystyrene-based anion exchange resin with quaternary amine functional groups. Engineered for high-performance industrial water treatment, this resin delivers exceptional demineralization efficiency and reliable silica removal across demanding applications.
Key Features
- Type I Quaternary Amine Structure: Superior chemical stability and higher operating temperature tolerance compared to Type II resins, ensuring long service life in industrial environments.
- Gel Polystyrene-DVB Matrix: Excellent mechanical strength and osmotic stability, minimizing bead breakage during regeneration cycles.
- High Total Exchange Capacity: ≥1.25 mmol/mL ensures thorough removal of anions including strong acid anions (SO₄²⁻, Cl⁻, NO₃⁻) and weak acid anions (SiO₂, CO₂).
- Effective Silica Removal: Optimized for silica leakage control below 0.02 mg/L in demineralization systems, critical for high-pressure boiler feed water.
- Broad pH Compatibility: Stable operation across pH 1-14 range, suitable for diverse chemical environments.
Applications
- Industrial boiler feed water demineralization
- Power plant condensate polishing systems
- Electronics-grade ultrapure water production
- Chemical processing and pharmaceutical water treatment
- Metal finishing wastewater treatment
