I-HEDP

I-Hydroxyethylidene diphosphonic acid (HEDP) sisikali se-organic phosphonic acid kunye ne-corrosion inhibitor eyenza ii-complexes ezizinzileyo ezinee-ion zesinyithi ezahlukeneyo, ezifana ne-iron, i-copper, kunye ne-zinc, kwaye inyibilikisa ii-oxides kwiindawo zesinyithi.

Ihlala isebenza kakuhle ekuthinteleni ukugqwala kunye nokwakheka kwezikali nokuba ikwi-250°C, ihlala izinzile kumanqanaba aphezulu e-pH, kwaye iyamelana ne-hydrolysis. I-HEDP ibonakalisa ukumelana okungcono nee-acids, ii-alkalis, kunye ne-chlorine oxidation kunezinye ii-organic phosphonic acids (kunye neetyuwa zazo).
