ZGA 351-FZ styrene series macroporous strong basic anion exchange resin

Description

1. Description

“Hydrolite” ZGA 351-FZ is a type of anion exchange resin containing a quaternary ammonium group [-N(CH3 ₎ 3OH _] in a styrene-diethylenebenzene copolymer with a macroporous structure. It is used together with ZGC 151-FZ anion resin. A key feature is the smaller average size of the cationic resin than the anionic resin, which is called “inverse-traditional mixed bead resin.” It is specifically used for the production of pure and ultrapure water in mixed systems and for condensate polishing. It has characteristics such as uniform granule size, clear stratification in the mixed bed, and uniform mixing ability. This significantly improves the quality of the mixed bed feedwater, increases the water production volume per cycle, and reduces regeneration costs. This product has received a Chinese patent.
