ZGC 258SC macroporous acrylic acid series weak acid cation exchange resin

Description

1. Description:

Hydrolite ZGC 258SC is a cation exchange resin containing a carboxyl group (-COOH) in an acrylic acid copolymer with a macroporous structure. Strongly acidic cation exchange resins, along with weakly acidic cation exchange resins, are used to produce pure and ultrapure water in a cationic two-layer system. The significant difference in true density and grain size distribution between the strong and weak resins ensures excellent hydrodynamic properties and a noticeable separation effect.

2. Implementation standard: HG/T2164-1991 DL/T519-2004 SH2605.05-2003
