I-HEDP Cas 2809-21-4 I-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 Yamamolekyuli: C2H8O7P2
Sebenzisa
I-HEDP uhlobo lwe-cathodic corrosion inhibitor. Uma iqhathaniswa nama-phosphate angaphili, ingahlanganiswa ne-sodium molybdate, i-silicate, usawoti we-zinc kanye ne-co-polymer ikakhulukazi njenge-scale corrosion inhibitor ekwelapheni amanzi okupholisa ajikelezayo, i-oil field flash kanye namanzi e-boiler. Ingasetshenziswa futhi njenge-sequestrant ku-detergent kanye ne-complexing agent kanye ne-metal scour ku-electroplating.
Isici
I-HEDP ingase ihlukane ibe ama-ion amahlanu amahle noma amabi bese ikhipha i-ion yensimbi ene-valent ezimbili emanzini. Ngakho-ke ithatha umphumela omuhle wokuvimbela isikali. Lo mkhiqizo uwubufakazi bokumelana nokushisa okuphezulu, i-oxidizing kanye nenani eliphezulu le-pH. Ibonisa umphumela ophelele we-synergic kanye nomphumela wokuxazulula umkhawulo ngenkathi ihlanganiswa nezinye izithibi zokugqwala kanye nezithibi zesikali.

Ukusetshenziswa
I-HEDP ingahlanganiswa ne-hydroxylaectic acid, i-PAA, i-BTA, i-molybdate, i-copolymer, usawoti we-zinc, ukwenza i-alkali e-organic noma i-phosphorus ephansi yokwelapha amanzi ukuze isetshenziswe kuzo zonke izinhlobo zezinhlelo zamanzi okupholisa ezijikelezayo ezihlukile kwikhwalithi yamanzi. Umthamo ngokuvamile u-2~10mg/L kuyilapho i-HEDP isetshenziswa yodwa.
Iphakheji kanye nesitoreji
Isigubhu sepulasitiki esingu-250kg noma i-IBC engu-1250kg, kufanele sigcinwe ekamelweni elipholile nelinomoya isikhathi sonyaka owodwa.
Sicela usithinte ukuze uthole i-COA kanye ne-MSDS. Ngiyabonga.
