Suqing 313 from Suqing's acrylic-based gel-type weak-base anion exchange resin range is a high-performance gel-type weak-base anion exchange resin developed for complex high-organic-matter water treatment and deep material refinement. With free amine ionic form, it appears as colorless transparent spherical particles, featuring excellent resistance to organic pollution and efficient ion exchange performance
Excellent resistance to organic pollution - High tolerance to various organic matters in water, not easy to be contaminated and clogged, suitable for complex and harsh water quality, long service life.
Efficient deacidification and decolorization - Precise ion exchange selectivity, can quickly remove acidic impurities and colored substances in materials, significantly improving material purity and appearance quality.
Outstanding mechanical strength - Post-grinding sphericity ≥90%, strong resistance to abrasion and hydraulic impact, not easy to break during long-term operation, ensuring stable system operation
High-organic-matter wastewater treatment: Treatment of high-organic-matter wastewater in printing and dyeing, chemical, papermaking and other industries, reducing COD and organic matter content to achieve compliance with discharge standards.
Food material refinement: Deacidification and decolorization in the production of food additives, starch sugar, etc., ensuring product purity and edible safety.
Pharmaceutical intermediate refinement: Removal of acidic impurities and decolorization in the production of pharmaceutical intermediates, ensuring intermediate purity meets subsequent synthetic reaction requirements.
