Izici:
I-HEDP iyi-organophosphoric acid corrosion inhibitor. Ingakwazi ukucula nge-Fe, Cu, ne-Zn njll.
ama-ion ensimbi futhi enze inhlanganisela ezinzile eyinkimbinkimbi.
Ingancibilikisa izinto ezenziwe nge-oxidized ezindaweni zalezi zinsimbi. Ngaphansi kuka-250℃ HEDP ikhombisa isikali esihle kakhulu nekhono lokuvimbela ukugqwala.
I-HEDP inokuqina okuhle kwamakhemikhali ngaphansi kwevelu ye-pH ephezulu, okunzima ukuyikhipha emanzini, futhi okunzima ukubola ngaphansi kwezimo ezivamile zokukhanya nokushisa. Ukubekezelela i-asidi/i-alkali kanye ne-chlorine oxidation kungcono kunokwamanye ama-organophosphoric acid (usawoti).
I-HEDP ingasabela ngama-ion ensimbi ohlelweni lwamanzi ukuze yakhe inkimbinkimbi ye-hexa-element chelating, ikakhulukazi i-calcium ion. Ngakho-ke, i-HEDP inemiphumela emihle ye-antiscale kanye ne-threshold ebonakalayo.
Uma yakhiwe kanye namanye amakhemikhali okuhlanza amanzi, ikhombisa imiphumela emihle ye-synergistic.
I-HEDP eqinile ingumkhiqizo wokuhlanzeka okuphezulu, olungele ukusetshenziswa ezifundeni zasebusika nezibandayo.
ilungele ukusetshenziswa njenge-ejenti yokuhlanza emikhakheni ye-elekthronikhi nanjengezithasiselo kumakhemikhali ansuku zonke.
Izicelo:
I-HEDP isetshenziswa kabanzi ohlelweni lokujikeleza lwamanzi apholile amandla kagesi, imboni yamakhemikhali, i-metallurgy, umanyolo, njll. futhi isetshenziswa kabanzi njengesikali ne-corrosion inhibitor yama-boilers anengcindezi ephansi, i-waterflood, ipayipi likawoyela.
Embonini yokukhanya nendwangu, i-HEDP isetshenziswa njengesihlanzi sensimbi nesingeyona insimbi. Embonini yokudaya, i-HEDP isetshenziswa njenge-peroxide stabilizer kanye ne-ejenti yokulungisa udayi; Ku-electroplating engeyona i-cyanide, i-HEDP isetshenziswa njenge-ejenti yokuchela. Umthamo we-1-10mg/L ukhethwa njenge-scale inhibitor, 10-50mg/L njenge-corrosion inhibitor, kanye ne-1000-2000mg/L njengesihlanzi. Ngokuvamile, i-HEDP isetshenziswa kanye ne-polycarboxylic acid.
