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 yeCAS: 2809-21-4
Ifomula yemolekyuli: C2H8O7P2
Sebenzisa
I-HEDP luhlobo lwe-cathodic corrosion inhibitor. Xa kuthelekiswa ne-phosphates ye-inorganic, inokudibaniswa ne-sodium molybdate, i-silicate, ityuwa ye-zinc kunye ne-co-polymer ngokuyinhloko njenge-scale corrosion inhibitor kunyango lwamanzi okupholisa i-cyclic, i-oil field flash kunye ne-boiler water .Inokusetyenziswa njenge-sequestrant kwi-detergent kunye ne-agent eyinkimbinkimbi kunye ne-metal scour kwi-electroplating.
Uphawu
I-HEDP inokudityaniswa kwii-ion ezintlanu ezi-positive okanye ezi-negative kwaye zichelate i-ayoni yesinyithi eneentsimbi ezimbini emanzini. Yiyo ke loo nto ithatha isikali esihle sokuthintela isiphumo. Le mveliso ibubungqina obuchasene nobushushu obuphezulu, i-oxidizing kunye nexabiso eliphezulu le-pH. Ibonisa isiphumo esigqibeleleyo se-synergic kunye nesiphumo sokusombulula umda ngelixa idityaniswa nezinye ii-corrosion inhibitors kunye ne-scale inhibitors.

Ukusetyenziswa
I-HEDP inokudityaniswa ne-hydroxylaectic acid, i-PAA, i-BTA, i-molybdate, i-copolymer, i-zinc ityuwa, ukwenza i-alkali yonke-organic-alkali okanye i-low-phosphor i-agent esekelwe kwi-zinc-based based agent yonyango lwamanzi ukuze isetyenziswe kuzo zonke iintlobo ze-cyclic zokupholisa iinkqubo zamanzi ahlukeneyo kumgangatho wamanzi. Idosi ngokubanzi yi-2 ~ 10mg/L ngelixa i-HEDP isetyenziswa yodwa.
