Talosaga:
1.HEDP o loʻo faʻaaogaina e pei o le fua ma le corrosion inhibition i le faʻasalalauina o le vai malulu, suauʻu suauʻu ma le maualalo o le vevela i totonu o fanua e pei o le eletise eletise, alamanuia vailaʻau, metallurgy, fertilizer, ma isi.
2.In lalaga lalaga mama, HEDP e faʻaaogaina e fai ma faʻamama mo uʻamea ma mea e le faʻaaogaina. I totonu o pisinisi vali, o le HEDP o loʻo faʻaaogaina e pei o le peroxide stabilizer ma le vailaʻau faʻapipiʻi;
3.In non-cyanide electroplating, HEDP faʻaaogaina e fai ma sui chelating. Ole fua ole 1-10mg/L e mana'omia e fai ma fa'ainitaneti fua, 10-50mg/L e pei ole fa'a'au'au, ma le 1000-2000mg/L e fa'amama.
4. E masani lava, HEDP e faʻaaogaina faʻatasi ma polycarboxylic acid.
