HEDP bụ ihe na-egbochi corrosion acid organophosphoric. Ọ nwere ike iji ion Fe, Cu, na Zn chelate iji mepụta ihe ndị na-eme ka chelating sie ike. Ọ nwere ike ịgbaze ihe ndị e ji oxidized mee n'elu ọla ndị a. HEDP na-egosi oke nha na mmetụta mgbochi nchara dị mma n'okpuru okpomọkụ 250 ℃. HEDP nwere ezigbo nkwụsi ike kemịkalụ n'okpuru oke pH dị elu, ọ siri ike ịgbaze, ọ na-esikwa ike ịgbaze n'okpuru ìhè na okpomọkụ nkịtị. Nkwenye oxidation acid/alkali na chlorine ya ka mma karịa nke organophosphoric acids (nnu). HEDP nwere ike imeghachi omume na ion ígwè dị na sistemu mmiri iji mepụta hexa-element chelating complex, ọkachasị calcium ion. Ya mere, HEDP nwere ezigbo mmetụta mgbochi oke na nke a na-ahụ anya. Mgbe ejiri kemịkalụ ndị ọzọ na-agwọ mmiri rụọ ya, ọ na-egosi ezigbo mmetụta njikọta. HEDP bụ ntụ kristal, ọ dị mma maka ojiji n'oge oyi na mpaghara oyi. N'ihi ịdị ọcha ya dị elu, enwere ike iji ya dị ka ihe nhicha n'ọhịa eletrọniki yana dị ka ihe mgbakwunye na kemịkalụ kwa ụbọchị.
HEDP A na-eji ya dịka ihe mgbochi oke na mmebi n'ime sistemụ mmiri oyi na-agagharị, ebe mmanụ na obere ihe na-ekpo ọkụ n'ọhịa dịka ike eletrik, ụlọ ọrụ kemịkalụ, igwe ígwè, fatịlaịza, wdg. Na ụlọ ọrụ kpara ákwà dị mfe, HEDP A na-eji ya dị ka ihe e ji asa ákwà maka ígwè na ihe na-abụghị ígwè. HEDP A na-eji ya dị ka ihe na-eme ka peroxide sie ike ma na-edozi agba; N'ime ihe na-abụghị cyanide electroplating, HEDP A na-eji ya dị ka ihe na-eme ka ihe dị nro. A na-ahọrọ usoro 1-10mg/L dị ka ihe na-egbochi ihe dị ka nha, 10-50mg/L dị ka ihe na-egbochi ihe na-emebi emebi, na 1000-2000mg/L dị ka ihe na-asa ahụ. HEDP A na-ejikarị ya na polycarboxylic acid.
