Robust polymer structure ensures long-term chemical stability and resistance to degradation during repeated regeneration cycles.
Capable of maintaining optimal performance at maximum operating temperatures up to 100°C.
Exceptional ion exchange capacity ensures the production of high-purity water and precise element separation.
Strict control of particle size (0.4-0.9mm) minimizes flow bias and prevents column clogging.
Highly effective for pure water, wastewater, and hydrometallurgy across various industrial sectors.
Fast exchange rates and efficient regeneration with standard NaOH and HCl agents.
Utilize flocculation and sand filtration to remove suspended solids and prevent pore jamming.
Maintain operating velocity between 2-10 BV/h to optimize ion exchange efficiency.
Precise regeneration using 3-5% HCl and 2-4% NaOH at 1-2 BV/h velocity.
Ensure reasonable diameter ratios to avoid bias currents and ensure uniform liquid distribution.
Use back-flushing to remove air bubbles and loosen resin agglomeration during storage.
Preserve in wet state above 0°C; use 5% salt water for long-term inactive storage.

It is primarily used for pure water preparation, industrial wastewater treatment, and the separation of rare elements in wet metallurgy processes.
The resin must be kept in a wet state above 0°C. For long-term storage, it should be placed in a closed space or submerged in a 5% salt water solution to prevent dehydration.
Regeneration is typically achieved using 2BV of 3-5% HCl followed by 2BV of 2-4% NaOH, following the alkali-water-acid-water flow path.
Implement pre-treatment steps such as flocculation, filtration, or sand-filtration to ensure no suspended solids enter the resin bed.
Yes, the 201X7 MB is designed to withstand maximum operating temperatures of up to 100°C.
A low uniformity coefficient (≤1.4) indicates a consistent particle size, which prevents "channeling" and ensures the liquid flows evenly through the entire resin bed.
