ZGC 151-FZ styrene series macroporous strongly acidic cation exchange resin

Description

1. Description

Hydrolite ZGC 151-FZ is a type of cation exchange resin containing a sulfonic acid group (-SO3H ₎ in a styrene-diethylenebenzene copolymer with a macroporous structure. It is used in conjunction with the D201-FZ anion exchange resin. Its key feature is the smaller average size of the cationic resin than the anionic resin, thus representing a “reverse-conventional mixed-bed resin.” It is specifically used for producing pure and ultrapure water in mixed systems and for polishing condensate. Its characteristics include uniform granule size, clear stratification in the mixed bed, and the ability to uniformly mix. 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.
