Poly(dimethylamine-co-epichlorohydrin-co-ethylenediamine) CAS 42751-79-1

Polyamine waa polymers cationic dareere ah oo miisaankoodu kala duwan yahay kaas oo si hufan u shaqeeya sida xinjiriyeyaasha aasaasiga ah oo dallaca wakiilada dhexdhexaadinta ee hababka kala-soocidda dareeraha-adag ee warshadaha kala duwan.

Alaabada waxaa loo isticmaali karaa in lagu qaso xinjirowga aan noolaha ahayn, sida polyaluminium chloride ama alum si loogu daweeyo biyaha wasakhda ah ee hooseeya ama biyaha tuubada. Waxa kale oo loo isticmaali karaa sifaynta biyaha wasakhda ah ee laga soo saaro saliidda, ama sida qashinka anionic ee nidaamka biyaha cad ee samaynta warqad.
