1-Hydroxyethylidene-1,1-Diphosphonic Acid (HEDP)
Nomoro ea CAS: 2809-21-4
Foromo ea molek'hule: C2H8O7P2
Sebelisa
HEDP ke mofuta oa cathodic corrosion inhibitor.Ha e bapisoa le inorganic phosphates, e ka kopanngoa le sodium molybdate, silicate, letsoai la zinki le co-polymer haholo-holo e le scale corrosion inhibitor ha ho phekoloa metsi a pholileng a cyclic, flash field le metsi a boiler .E ka boela ea sebelisoa e le sequestrant ka sesepa le complexing agent le metal scour ka electroplating.
Sebopeho
HEDP e ka kopanya li-ion tse hlano tse positive kapa tse mpe 'me tsa chelate ione ea tšepe e nang le li-valent tse peli metsing.Kahoo ho nka phello e ntle ea ho thibela.Sehlahisoa sena ke bopaki khahlanong le mocheso o phahameng, oxidizing le boleng bo phahameng ba pH.E bonts'a phello e phethahetseng ea synergic le phello ea ho rarolla bothata ha e ntse e kopanngoa le li-corrosion inhibitors tse ling le scale inhibitors.
