Food-Grade Macroporous Weak Base Styrene Series Anion Exchange Resin
for General Decoloring and Deodorizing in Industrial Purification Processing
PRODUCT DATA SHEET:
KP-307A is a food-grade macroporous weakly basic styrene-based anion exchange resin. Attributed to its uniform and solid structure and low swelling rate after ionic state transition, it performs with strong resistance to osmotic shock. By its special weak-base groups' electrostatic pull, KP-307A performs strong adsorbability in organic strong-negative ions of organic pigment and odor molecules as well as exclusive exchange with inorganic strong acid radicals only, despite weak-acid radicals or weak organic anions coexisting within. Besides, its weak-base groups qualify its properties of easy-elution and high regeneration capacity upon reaching saturated so that the overall exchange capacity and resin service cycle are rather upgraded.
Specifically, the very advantages to using KP-307A lie in its high selective adsorption for inorganic strong acid radicals of metal salts and nonmetal minerals, such as SO4 2- , NO32-, Cl-, F- or strong base radical OH-, as well as its extra large exchange capacity with negative organic molecules and nonpolar organics that generally are composed of odor and pigments, as opposed to its disadvantages of incapability to capturing weak acids neither positive organic ions.
In response to the call of combined applications for securing complete deionization, decolorization&deodorization, cation-exchange resin model KP-007 is often primarily applied ahead, followed by two congeneric anion-exchange resin models, scilicet KP-307A first and KP-2027A after. Thanks to its exclusive selectivity and high regeneration &exchange property that its weak-base groups empower, priority-use of KP-307A can massively eliminate large amounts of strong-acids and negative organics before KP-2027A's intense porosity get blocked and polluted prior to be in service.
Altogether, these three applications alliance serve the common purpose of demineralizing, decoloring and deodorizing process in food production, pharmaceutical and biochemical engineering, and the like.
