D113 Water Filter Macroporous Weak Acid Cation Exchange Resin 99.9% Purity

This acrylic series cation exchange resin adopts advanced one-step single polymerization technology, taking cross-linked acrylic copolymer as the base skeleton and grafted with carboxylic acid functional groups as the exchange medium. The product stands out with ultra-high saturated exchange capacity, stable overall structure with negligible expansion and contraction before and after regeneration, robust mechanical hardness against particle crushing, as well as outstanding chemical tolerance, strong anti-oxidation and anti-pollution resistance, together with ultra-fast mass transfer and exchange speed.

Versatile in adaptability, it perfectly fits complex working conditions such as high-flow mixed bed operation, food fermentation refining, hydrometallurgical separation and industrial catalytic dehydration. It maintains steady performance for long-cycle continuous operation, lowers overall system maintenance cost, and acts as a multi-functional high-performance medium for water purification, ingredient refining and resource separation across industrial segments.

Ideal for high-speed mixed bed water treatment systems and boiler feed water softening projects. It efficiently traps calcium, magnesium and other hardness-forming cations to reduce water alkalinity and scale formation. Suitable for continuous large-flow water making scenarios, it maintains stable effluent water quality, lowers equipment scaling and corrosion risks, and supports long-cycle unmanned operation of pure water and ultra-pure water preparation systems.

Commonly deployed in hydrometallurgical leachate treatment and rare element isolation processes. By virtue of its selective adsorption performance, it achieves targeted capture, separation and enrichment of rare and valuable element ions from raw material liquid. It features easy desorption and stable regeneration performance, effectively elevates resource utilization rate and product purity, and meets the high-standard separation demands of modern metallurgical and rare material industries.

Extensively adopted in biochemical substance extraction and antibiotic separation working procedures. With mild adsorption characteristics and stable structural inertia, it can separate target active components from fermentation liquid without destroying effective substances, strip miscellaneous ions and macromolecular impurities, greatly enhancing product purity and extraction yield. It fully adapts to the strict purification requirements of biochemical and biological manufacturing processes.

Widely used in the refining and purification links of sugar manufacturing, monosodium glutamate and other fermentation food industries. It effectively adsorbs impurity ions, pigments and heterologous substances in syrup and fermentation broth, clarifies liquid phase quality, optimizes production refining procedures, reduces processing loss, and strictly complies with food-grade application safety norms and industrial production standards.

Apart from water treatment and refining applications, it can be used as a solid acid catalyst and high-efficiency dehydrating medium in fine chemical synthesis. It delivers stable catalytic activity for organic synthesis reactions, meanwhile it can adsorb and remove trace moisture in raw materials and solvents. Featuring stable chemical property and easy regeneration, it is an economical and practical auxiliary material for chemical production and material drying.
