I-HEDP sisithinteli sokugqwala kwe-organophosphorus acid. Singakwazi ukunyibilikisa ii-ion ze-Fe, Cu, kunye ne-Zn ukuze senze iikhompawundi ze-chelating ezizinzileyo. Singakwazi ukunyibilikisa izinto ezi-oxidized kwiindawo zesinyithi. I-HEDP ibonisa iziphumo ezibalaseleyo zokuthintela ukugqwala kunye nobukhulu phantsi kobushushu obuyi-250℃. I-HEDP inozinzo oluhle lweekhemikhali phantsi kwexabiso eliphezulu le-pH, kunzima ukuyinyibilikisa emanzini, kwaye kunzima ukuyibolisa phantsi kokukhanya okuqhelekileyo kunye neemeko zobushushu. Ukunyamezela kwayo i-asidi/i-alkali kunye ne-chlorine oxidation kungcono kunokwezinye ii-organophosphorus acids (ityuwa). I-HEDP Zingasabela kunye nee-ion zesinyithi kwinkqubo yamanzi ukuze zenze i-hexa-element chelating complex, ngokukodwa i-calcium ion. Ke ngoko, I-HEDP inemiphumo emihle yokungalingani kakuhle kunye nemiphumo ebonakalayo. Xa yakhiwe kunye nezinye iikhemikhali zonyango lwamanzi, ibonisa imiphumo emihle yokusebenzisana. Imeko eqinileyo ye I-HEDP yi-crystal powder, efanelekileyo ukusetyenziswa ebusika nakwiindawo ezibandayo. Ngenxa yokuba icocekile kakhulu, ingasetyenziswa njengesixhobo sokucoca kwiindawo ze-elektroniki nanjengezongezo kwiikhemikhali zemihla ngemihla.
I-HEDP isetyenziswa njengesikali kunye nokuthintela ukugqwala kwinkqubo yamanzi abandayo ajikelezayo, intsimi yeoyile kunye neebhoyila ezinoxinzelelo oluphantsi kwiindawo ezifana namandla ombane, ishishini leekhemikhali, isinyithi, isichumisi, njl.njl. Kwishishini elilukiweyo olukhaphukhaphu, I-HEDP isetyenziswa njengesepha yokuthambisa isinyithi kunye ne-nonmetal. Kwishishini lokudaya, I-HEDP isetyenziswa njenge-peroxide stabilizer kunye ne-dye-fixing agent; Kwi-electroplating engeyiyo i-cyanide, I-HEDP isetyenziswa njenge-chelating agent. Umlinganiselo we-1-10mg/L ukhethwa njenge-scale inhibitor, i-10-50mg/L njenge-corrosion inhibitor, kunye ne-1000-2000mg/L njengesepha. Ngokwesiqhelo, I-HEDP isetyenziswa kunye ne-polycarboxylic acid.
