HEDP yi-organophosphoric acid corrosion inhibitor. Inokuthi i-chelate kunye ne-Fe, Cu, kunye ne-Zn ions ukwenza iikhompawundi ze-chelating ezizinzile.HEDPibonisa isikali esigqwesileyo kunye neziphumo zokuthintela umhlwa phantsi kobushushu obungama-250 ℃.HEDP inozinzo lwekhemikhali elungileyo phantsi kwexabiso eliphezulu le-pH, kunzima ukuba i-hydrolyzed, kwaye kunzima ukubola phantsi kokukhanya okuqhelekileyo kunye neemeko zobushushu. I-asidi yayo / i-alkali kunye nokunyamezela kwe-chlorine oxidation kungcono kunezinye i-organophosphoric acids (ityuwa).HEDP inokusabela ngee-ion zetsimbi kwinkqubo yamanzi ukwenza i-hexa-element chelating complex, kunye ne-calcium ion ngokukodwa. Ngoko ke,HEDP ine-antiscale elungileyo kunye neziphumo ezibonakalayo zomda. Xa yakhiwe kunye nezinye iikhemikhali zokunyanga amanzi, ibonisa iziphumo ezilungileyo ze-synergistic. Ubume obuqinileyo beHEDP ngumgubo wekristale, olungele ukusetyenziswa ebusika kunye nezithili ezibandayo. Ngenxa yokucoceka kwayo okuphezulu, inokusetyenziswa njenge-arhente yokucoca kwiindawo ze-elektroniki kunye nezongezo kwiikhemikhali zemihla ngemihla.
HEDPisetyenziswa njengesikali kunye nokuthintela umhlwa ekujikelezeni inkqubo yamanzi epholileyo, intsimi yeoli kunye neebhoyila ezinoxinzelelo oluphantsi kwimimandla efana namandla ombane, ishishini lemichiza, isinyithi, isichumisi, njl.HEDP isetyenziswa njengesicoci sesinyithi kunye ne-nonmetal. Kwishishini lokudaya,HEDP isetyenziswe njenge-peroxide stabilizer kunye ne-agent yokulungisa idayi; Kwi-non-cyanide electroplating,HEDP isetyenziswa njenge arhente chelating. I-dosage ye-1-10mg / L ikhethwa njenge-inhibitor yesikali, i-10-50mg / L njenge-corrosion inhibitor, kunye ne-1000-2000mg / L njenge-detergent. Ngesiqhelo,HEDPIsetyenziswa kunye ne-polycarboxylic acid.
