I-HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
I-1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
I-1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Inombolo ye-CAS: 2809-21-4
Ifomula yeMolekyuli: C2H8O7P2
Sebenzisa
I-HEDP luhlobo lwe-cathodic corrosion inhibitor. Xa ithelekiswa ne-phosphates ezingaphiliyo, inokuhlanganiswa ne-sodium molybdate, i-silicate, ityuwa ye-zinc kunye ne-co-polymer ikakhulu njenge-scale corrosion inhibitor ekunyangeni amanzi okupholisa ajikelezayo, i-oil field flash kunye namanzi e-boiler. Ingasetyenziswa njenge-sequestrant kwi-detergent kunye ne-complexing agent kunye ne-metal scour kwi-electroplating.
Uphawu
I-HEDP inokuthi idibanise i-ion ezintlanu ezintle okanye ezimbi ize idibanise i-ion yesinyithi esine-valent ezimbini emanzini. Ngoko ke ithatha isiphumo esihle sokuthintela isikali. Le mveliso ingqina ubushushu obuphezulu, i-oxidizing kunye nexabiso eliphezulu le-pH. Ibonisa isiphumo esigqibeleleyo se-synergic kunye nesiphumo sokusombulula umda ngelixa idityaniswe nezinye izithinteli zokubola kunye nezithinteli zesikali.

Ukusetyenziswa
I-HEDP ingadityaniswa ne-hydroxylaectic acid, i-PAA, i-BTA, i-molybdate, i-copolymer, ityuwa ye-zinc, ukwenza i-arhente ye-zinc esekelwe kwi-alkali epheleleyo okanye i-phosphorus ephantsi yonyango lwamanzi ukuze isetyenziswe kuzo zonke iintlobo zeenkqubo zamanzi okupholisa ezijikelezayo ezahlukileyo kumgangatho wamanzi. Idosi ngokubanzi yi-2~10mg/L ngelixa i-HEDP isetyenziswa yodwa.
