HEDP ke organophosphoric acid corrosion inhibitor. E ka chelate ka li-ion tsa Fe, Cu, le Zn ho theha metsoako e tsitsitseng ea chelating. E ka qhala lisebelisoa tse nang le oxidized holim'a litšepe tsena.HEDPe bonts'a litlamorao tse ntle haholo tsa ho thibela kutu le ho thibela ho bola tlas'a mocheso oa 250 ℃.HEDP e na le botsitso bo botle ba lik'hemik'hale tlas'a boleng bo phahameng ba pH, e thata ho etsoa ka hydrolyzed, 'me e thata ho bola 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, e nang le calcium ion haholo-holo. Ka hona,HEDP e na le litlamorao tse ntle tsa antiscale le tse bonoang. Ha e hahiloe hammoho le lik'hemik'hale tse ling tsa ho hloekisa metsi, e bontša liphello tse ntle tsa synergistic. Boemo bo tiileng baHEDP ke phofo ea kristale, e loketseng ho sebelisoa literekeng tsa mariha le tse batang. Ka lebaka la bohloeki ba eona bo phahameng, e ka sebelisoa e le sesebelisoa sa ho hloekisa masimong a elektroniki le joalo ka litlatsetso tsa lik'hemik'hale tsa letsatsi le letsatsi.
HEDPe sebelisoa e le thibelo ea sekhahla le ho bola ha ho potoloha tsamaiso ea metsi a pholileng, tšimo ea oli le li-boilers tse nang le khatello e tlaase masimong a kang matla a motlakase, indasteri ea lik'hemik'hale, metallurgy, manyolo, joalo-joalo.HEDP se sebedisoang joalo ka sehlatsoa sa tšepe le sa tšepe. Ka indasteri ea ho daea,HEDP e sebelisoa e le "peroxide stabilizer" le "dae-fixing"; Ka electroplating e seng cyanide,HEDP e sebelisoa joalo ka chelating agent. Tekanyo ea 1-10mg/L e khethoa e le scale inhibitor, 10-50mg/L e le corrosion inhibitor, le 1000-2000mg/L e le sesepa. Hangata,HEDPE sebelisoa hammoho le polycarboxylic acid.
