ZGA 451SC macroporous styrene series weakly acid exchange anion exchange resin

Description

1. Description:

“Hydrolite” ZGA 451sc is a type of anion exchange resin with a tertiary amine group [-N(CH3)2] in a washing-diethylenebenzene copolymer with a macroporous structure. The strongly acidic cation exchange resin, _together with _the weakly acidic cation exchange resin, is used to produce pure and ultrapure water in a dual cation bed system. Because the true density and grain size distribution differ significantly between the strong and weak resins, the hydrodynamic behavior of the resin is excellent, and the separation effect is clearly visible.
