I-HEDP iyisivimbeli sokugqwala kwe-organophosphorus acid. Ingaxubana nama-ion e-Fe, Cu, kanye ne-Zn ukuze yakhe ama-compound e-chelating azinzile. Ingancibilikisa izinto ezi-oxidized ezindaweni zalezi zinsimbi. I-HEDP ikhombisa imiphumela emihle kakhulu yokuvimbela ukugqwala kanye nobukhulu ngaphansi kokushisa okungu-250℃. I-HEDP inokuqina okuhle kwamakhemikhali ngaphansi kwenani eliphezulu le-pH, kunzima ukuyi-hydrolyzed, futhi kunzima ukuyibolisa ngaphansi kwezimo zokukhanya nokushisa ezivamile. Ukubekezelela kwayo i-acid/alkali kanye ne-chlorine oxidation kungcono kunokwezinye i-organophosphorus acid (usawoti). I-HEDP ingasabela nama-ion ensimbi ohlelweni lwamanzi ukuze yakhe i-hexa-element chelating complex, ikakhulukazi nge-calcium ion. Ngakho-ke, I-HEDP inemiphumela emihle yokumelana nesilinganiso kanye nemiphumela ebonakalayo yomkhawulo. Uma yakhiwe kanye namanye amakhemikhali okwelapha amanzi, ikhombisa imiphumela emihle yokusebenzisana. Isimo esiqinile se I-HEDP iyi-crystal powder, efanelekile ukusetshenziswa ebusika nasezindaweni ezibandayo. Ngenxa yobumsulwa bayo obuphezulu, ingasetshenziswa njenge-ejenti yokuhlanza emikhakheni ye-elekthronikhi kanye njengezengezo kumakhemikhali ansuku zonke.
I-HEDP isetshenziswa njengokuvimbela ukugqwala kanye nokukala ohlelweni lwamanzi abandayo olujikelezayo, insimu kawoyela kanye nama-boiler aphansi kwengcindezi emikhakheni efana namandla kagesi, imboni yamakhemikhali, i-metallurgy, umanyolo, njll. Embonini elukiwe kancane, I-HEDP isetshenziswa njengensipho yokuhlanza insimbi kanye nengeyona eyensimbi. Embonini yokudaya, I-HEDP isetshenziswa njengesiqinisi se-peroxide kanye ne-ejenti yokulungisa udayi; Ekufakeni i-electroplating okungeyona i-cyanide, I-HEDP isetshenziswa njenge-chelating agent. Umthamo we-1-10mg/L ukhethwa njenge-scale inhibitor, i-10-50mg/L njenge-corrosion inhibitor, kanye ne-1000-2000mg/L njengensipho yokuwasha. Ngokuvamile, I-HEDP isetshenziswa kanye ne-polycarboxylic acid.
