Iimbonakalo:
I-HEDP yi-organophosphoric acid corrosion inhibitor. Iyakwazi ukutshekisha ngeFe, Cu, kunye neZn njl.
ion zetsimbi kwaye zenze ikhompawundi ezinzileyo enzima.
Inokunyibilikisa imathiriyeli ene-oxidized kule miphezulu yesinyithi. Ngaphantsi kwe-250℃ HEDP ibonisa isikali esigqwesileyo kunye nesakhono sokuthintela umhlwa.
I-HEDP inozinzo olululo lweekhemikhali 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).
I-HEDP inokusabela ngee-ion zetsimbi kwinkqubo yamanzi ukwenza i-hexa-element chelating complex, kunye ne-calcium ion ngokukodwa. Ngoko ke, i-HEDP ine-antiscale efanelekileyo kunye nemiphumo ebonakalayo ebonakalayo.
Xa yakhiwe kunye nezinye iikhemikhali zokunyanga amanzi, ibonisa iziphumo ezilungileyo ze-synergistic.
I-SOD ye-HEDP yimveliso yococeko oluphezulu, ilungele ukusetyenziswa ebusika kunye nezithili ezibanda.
ikufanele kakhulu ukusetyenziswa njengearhente yokucoca kwimimandla ye-elektroniki nanjengezongezo kwiikhemikhali zemihla ngemihla.
Usetyenziso:
I-HEDP isetyenziswa ngokubanzi kwinkqubo yokujikeleza kwamanzi apholileyo amandla ombane, ishishini lemichiza, isinyithi, isichumisi, njl njl kwaye isetyenziswa ngokubanzi njengesikali kunye ne-corrosion inhibitor yeebhoyila ezinoxinzelelo oluphantsi, i-waterflood, i-oyile yepayipi.
Kwimizi-mveliso yokukhanya neyolukiweyo, i-HEDP isetyenziswa njengesicoci sesinyithi kunye nesingeyontsimbi. Kwishishini lokudaya, i-HEDP isetyenziswa njenge-peroxide stabilizer kunye ne-agent yokulungisa idayi; Kwi-non-cyanide electroplating, i-HEDP isetyenziswa njenge-agent 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. Ngokwesiqhelo, iHEDP isetyenziswa kunye nepolycarboxylic acid.
