杜笙（Tulsion）A-21S除六價(jià)鉻樹脂
"無裂紋"強(qiáng)堿型陰離子交換樹脂I 型
Tulsion® A-21 S 是一款聚苯乙烯架構(gòu)的強(qiáng)堿型陰離子交換樹脂。它具有優(yōu)越的化學(xué)性
能的特殊的銨官能基，并且由于其tr的無裂紋特性而具有優(yōu)異的操作性能。
Tulsion® A-21 S 當(dāng)與強(qiáng)酸型陽離子交換樹脂一起用在水處理中時(shí)，對(duì)于弱酸，強(qiáng)無機(jī)
酸和鹵化物等具有{jj0}的操作性能。
Tulsion® A-21 S 以一定的粒徑范圍生產(chǎn)供應(yīng)，為氯型的濕潤球狀，具有良好的動(dòng)力性
和最小的壓降。
