Fuafuaga mole: C₂H₆O₇P₂Ua uma₂ Mole mole mamafa: 250

Fua Fa'atatau:

Meatotino:

HEDP•I₂ o se iniseti corrosion acid organophosphonic, e mafai ona chelate ma Fe, Cu, ma Zn ions, e mafai ona soloia mea oxidized, e lelei fua ma corrosion inhibition aafiaga e oo lava i lalo o le 250 ℃, e mautu i lalo o le maualuga pH tau, e le faigofie ia hydrolyzed, e le faigofie ona pala i lalo o le malamalama masani ma le vevela, o lona acid / alkaline ma le chloride oxidation faapalepale e sili atu nai lo isi acids organophosph-onic. HEDP•I₂ e mafai ona fa'atupu fa'atasiga chelating ono mama fa'atasi ma ion u'amea i totonu o le vai, aemaise lava Ca2 +. HEDP•I₂ o lo'o i ai a'afiaga fa'asaina fua lelei ma a'afiaga fa'amata'u fa'ate'aina. A fa'aoga fa'atasi ma isi vaila'au Togafitiga Suavai, e sili atu a'afiaga fa'atasi.
