Product Description

D202 Styrene Series Macroporous Strong Base Anion Exchange Resin
1. Description
D202 is a strongly basic type II gel anion exchange resin with quaternary amine groups [(CH3)2NC2H4OH] on a polymer matrix of a cross-linked structure of styrene and divinylbenzene copolymer. It has the characteristics of high working exchange capacity, easy regeneration, low alkali consumption during regeneration, strong anti-penetration ability, and high regeneration efficiency. Its alkalinity is equivalent to that of ordinary quaternary ammonium bases, and it exhibits ion exchange function in acidic, neutral, and even alkaline media. However, it has good physical and chemical stability, and its resistance to penetration, wear, and pollution is strong. This strongly basic anion resin is matched with a weakly basic anion resin and is used in the anion double-layer bed system to prepare pure water and high-purity water..
