I-HEDP Cas 2809-21-4 Etidronic Acid Monohydrate
I-1-Hydroxyethylidene-1,1-diphosphonic acid / HEDP CAS 2809-21-4
1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Inombolo ye-CAS: 2809-21-4
I-Molecular Formula: C2H8O7P2
Sebenzisa
I-HEDP wuhlobo lwe-cathodic corrosion inhibitor.Uma kuqhathaniswa nama-phosphates we-inorganic, ingahlanganiswa ne-sodium molybdate, i-silicate, usawoti we-zinc kanye ne-co-polymer ikakhulukazi njenge-scale corrosion inhibitor ekwelapheni amanzi okupholisa ama-cyclic, i-flash field yamafutha kanye namanzi abhayela .Ingasetshenziswa futhi njenge-sequestrant ku-detergent kanye i-ejenti eyinkimbinkimbi kanye ne-metal scour ku-electroplating.
Isici
I-HEDP ingase iboshelwe kuma-ion amahlanu ephozithivu noma anegethivu futhi ichelete i-ion yensimbi enamavalent amabili emanzini.Ngakho-ke kuthatha umphumela omuhle wokuvimbela.Lo mkhiqizo uwubufakazi ngokumelene nezinga lokushisa eliphezulu, i-oxidizing kanye nenani eliphezulu le-pH.Ibonisa umphumela ophelele we-synergic kanye nomphumela wokuxazulula i-threshold ngenkathi ihlanganiswa namanye ama-corrosion inhibitor nama-scale inhibitors.

Ukusetshenziswa
I-HEDP ingahlanganiswa ne-hydroxylaectic acid, i-PAA, i-BTA, i-molybdate, i-copolymer, usawoti we-zinc, ukwenza i-alkali egcwele-organic-alkali noma i-low-phosphor zinc-based ejenti yokwelashwa kwamanzi ukuze isetshenziswe kuzo zonke izinhlobo zamasistimu amanzi okupholisa ama-cyclic ahlukene. kusuka kwikhwalithi yamanzi.Umthamo ngokuvamile ngu-2~10mg/L kuyilapho i-HEDP isetshenziswa iyodwa.
Iphakheji kanye Nesitoreji
250kg isigubhu sepulasitiki noma i-1250kg IBC, okumele igcinwe egumbini elipholile nelinomoya omncane kanye neshalofu lesikhathi sonyaka owodwa.
Pls xhumana nathi ukuze uthole i-COA ne-MSDS.Ngiyabonga.
