Amfani
HEDP wani nau'i ne na mai hana lalatawar cathodic.Idan aka kwatanta da inorganic phosphates, shi za a iya compounded da sodium molybdate, silicate, zinc gishiri da kuma co-polymer, yafi a matsayin sikelin lalata hanawa a lura da cyclic ruwa sanyaya, mai filin filashi da tukunyar jirgi ruwa .It kuma za a iya amfani da matsayin sequestrant a wanka da kuma complexing wakili da karfe scour a electroplating.
Halaye
HEDP na iya ƙaddamar da ions guda biyar tabbatacce ko mara kyau kuma ya chelate ion ƙarfe mai ƙarfi biyu a cikin ruwa.Don haka yana ɗaukar sakamako mai hana ma'auni mai kyau.Wannan samfurin hujja ne akan babban zafin jiki, oxidizing da ƙimar pH mai girma.Yana nuna cikakkiyar tasirin aiki tare da warware tasirin ƙofa yayin da ake haɗa shi tare da sauran masu hana lalata da masu hana sikelin.
