HEDPo se mea faʻatei mea faasaʻosaʻo meaola oona oona. E mafai ona chelate ma Fe, Cu, ma Zn ions e fausia ai mautu chelating compound. E mafai ona faʻamamaina le oxidized mea i luga o nei metala 'luga.HEDP faʻaalia lelei sili fua ma faʻaleagaina aatiʻa aafiaga i lalo o le vevela 250 ℃. HEDPe i ai lelei lelei vailaʻau i lalo o le maualuga pH taua, faigata ona hydrolyzed, ma faigata ona decomposed lalo masani masani malamalama ma vevela tulaga. O lona faʻamalosiʻau / alkali ma le chlorine oxidation faʻapalepale e sili atu nai lo isi o totoga oona (masima).HEDPmafai ona tali atu i uamea uʻamea i le vai faiga e fausia ai hexa-elemeni chelating laʻasaga, ma kalisiu ion Ion. O lea,HEDPe i ai ni antiscale lelei ma vaʻaia faitotoʻa aʻafiaga. A fausia faʻatasi ma isi vai togafitiga vailaʻau, e faʻaalia lelei synergistic aʻafiaga. O le mautu setete oHEDPo tioata pauta, talafeagai mo le faʻaaogaina i le taumalulu ma 'aisa malulu. Ona o lona maualuga mama, e mafai ona faʻaaogaina o le faʻamamaina sooupu i eletise fanua ma avea faʻaopopo i aso uma vailaʻau.
HEDP o loʻo faʻaaoga e avea ma fua ma faʻalavelave faʻaleagaina i le faʻataʻamilomiloina o le suavai malulu, suauʻu ma paʻu maualalo-mamafa faʻapipiʻi i fanua pei o le eletise eletise, vailaʻau vailaʻau, metallurgy, fetilaisa, ma isi .. I malamalama lalagaina pisinisi, HEDPo loʻo faʻaaogaina e avea ma vailaʻau mo le uamea ma le leai ni metala. I galuega valiina,HEDPe faʻaaogaina o le peroxide stabilizer ma le vali e faʻamautu ai le sooupu; I le lē cyanide electroplating,HEDPe faʻaaogaina o le chelating agent. O le metotia o le 1-10mg / L e fiafia e avea ma fua faʻaola, 10-50mg / L e pei o le pala, ma 1000-2000mg / L e avea ma vailaʻau fufulu. Masani,HEDP e faʻaaogaina faʻatasi ma le polycarboxylic acid.
