ZGA455FD Macroporous Weak Basic Anion Exchange Resin

 

1. Introduction:

"Hydrolite" brand ZGA 455 FD is a sort of weakly basic anion exchange resin with poly styrene macroporous structure. This product has larger pore size and specific surface area, and it can absorb multiply large molecular organic, the normal adsorption rate can reach to 80-95%, the elution ratio can be more than 95%, so it is suitable for desalination and decolorization of sugar liquors. This product can also replace of active carbon to decolorize and refine some colorful liquid such as glycerin and glutamic acid etc, the treat cost is lower than particle active carbon.

ZGA455FD has the characteristics such as excellent mechanical intensity and high exchange capacity and low swelling rate. It could apply to industries of juices, drinks, potable water; moreover, remove salts and acid substances in food industry to improve the color and the taste of the products.

Note: ZGA455FD (ZG Export Product Type) is D354FD (ZG Domestic Product Type)
