I-hydroxyethylidene, 1,1-diphosphonic acidum (HedP)
CAS non: 2809-21-4
Molecular formula: C2H8O7P2
Usurpo
HedP est genus Cathodic corrosio inhibitor. Comparari cum inorganicis phosphates, potest componi cum sodium molybdate, silicate, cadmiae sal et co-polymer maxime ut scale corrosio inhibitor in treatment of Cyclic refrigerium aquam, oleum inhibitor in purgat et boiler et potest esse quod sequitur in purgant complexis agente et metallum Scourg in electroplating.
Proprium
HedP ut debond ad quinque ions positivum vel negative et chelate duos valent metallum Ion in aquis. Sic suus 'accipere bona scale inhibere effectum. Hoc productum est argumentum in altum temperatus, oxidizing et princeps PH pretii. Is ostendit perfectum synergic effectum solvendis limine effectus dum composita cum aliis corrosio inhibitors et scale inhibitors.
