ZGA 451FC styrene series macroporous weakly basic anion resins

Description

1. Description:

“Hydrolite” ZGA 451FC is a type of anion resin containing a tertiary amino group [-N(CH3)2] in a styrene-diethylenebenzene copolymer with a macroporous structure. This strongly basic anion resin, _together with _a weakened basic anion resin, is used to produce pure and ultrapure water in anion dual-chamber beds and anion dual-chamber floating beds, and can also be used in floating bed systems.

2. Standards implemented: HG/T2165-1991 DL/T519-2004 SH2605.09-2003
