ZGA 451 macroporous styrene series anion weakly basic exchange resin

 

1. Description

The "Hydrolite" ZGA 451 is a sort of anion exchange resin that has tertiary amine group [-N(CH3)2] in the styrene-diethylene benzene copolymer with macroporous structure. It is used mainly to produce pure water and ultra pure water, especially suitable for the treatment of the water resource with high content salt and organic substance, as well as treat waste water which contains chrome and decolorize sugar solution and so on.

2. Executing standards: HG/T2165-1991   DL/T519-2004   SH2605.09-2003
