Feme ea Phepelo HEDP e tsoang Chaena CAS:2809-21-4 e nang le Boleng bo Phahameng
Thepa
HEDP ke organophosphoric acid corrosion inhibitor. E ka chelate ka Fe, Cu, le Zn ions ho theha metsoako e tsitsitseng ea chelating. E ka qhala lisebelisoa tse nang le oxidized holim'a litšepe tsena.
HEDP e bonts'a sekala se setle haholo le litlamorao tsa thibelo ea kutu tlas'a mocheso oa 250°C.
HEDP e na le botsitso bo botle ba lik'hemik'hale tlas'a boleng bo phahameng ba PH, ho thata ho etsoa ka hydrolyzed, 'me ho thata ho bolisoa tlas'a khanya e tloaelehileng le maemo a mocheso. Mamello ea eona ea asiti / alkali le chlorine oxidation e betere ho feta ea li-organophosphoric acid tse ling (letsoai).
HEDP e ka sebetsana le li-ion tsa tšepe tsamaisong ea metsi ho etsa hexa-element chelating complex, haholo-holo calcium ion.
Ka hona, HEDP e na le litlamorao tse ntle tsa antiscale le tse bonahalang. Ha e hahiloe hammoho le lik'hemik'hale tse ling tsa ho hloekisa metsi, e bontša liphello tse ntle tsa synergistic.
