Ukusebenza

I-HEDPi-organophosphoric acid corrosion inhibitor. Ingazicebisa nge-Fe, Cu, ne-Zn ions ukwakha izinhlanganisela ezizinzile zokukhohlisa.Ingahlakaza izinto ezenziwe nge-oxidized kulezi zinsimbi.I-HEDP ikhombisa imiphumela emihle yokulinganisa nokugqwala ngaphansi kokushisa okungu-250 ℃. I-HEDPinokuzinza okuhle kwamakhemikhali ngaphansi kwenani eliphakeme le-pH, kunzima ukufakwa i-hydrolyzed, futhi kunzima ukubola ngaphansi kwezimo ezijwayelekile zokukhanya nokushisa. Ukubekezelelana kwe-acid / alkali kanye ne-chlorine oxidation kungcono kunamanye ama-acid e-organophosphoric (usawoti).I-HEDPingaphendula ngezinsimbi zensimbi ohlelweni lwamanzi ukwakha i-hexa-element chelating complex, ine-calcium ion ikakhulukazi. Ngakho-ke,I-HEDPinemiphumela emihle ye-antiscale nemiphumela ebonakalayo. Lapho yakhiwe kanye namanye amakhemikhali okwelashwa kwamanzi, ikhombisa imiphumela emihle yokusebenzisana. Isimo esiqinile seI-HEDPi-crystal powder, elungele ukusetshenziswa ezifundeni zasebusika naseziqandeni. Ngenxa yokuhlanzeka kwayo okuphezulu, ingasetshenziswa njenge-ejenti yokuhlanza emikhakheni ye-elektroniki nanjengezithasiselo kumakhemikhali ansuku zonke.

Isicelo

I-HEDP isetshenziswa njengesikali nokuvimbela ukugqwala ekujikelezeni uhlelo lwamanzi apholile, insimu kawoyela kanye namabilisi aphansi anengcindezi emikhakheni efana namandla kagesi, imboni yamakhemikhali, insimbi, umanyolo, njll. Emkhakheni okhanyayo, I-HEDPisetshenziswa njengomuthi wokuhlanza wensimbi nonmetal. Emkhakheni wokudaya,I-HEDPisetshenziswa njenge-peroxide stabilizer ne-agent yokulungisa udayi; Ku-non-cyanide electroplating,I-HEDPisetshenziswa njenge-ejenti yokukhohlisa. Umthamo we-1-10mg / L uncanyelwa njengesikali se-inhibitor, 10-50mg / L njenge-corrosion inhibitor, kanye ne-1000-2000mg / L njenge-detergent. Imvamisa,I-HEDP isetshenziswa kanye ne-polycarboxylic acid.

Ukupakisha nokugcina

Uketshezi lwe-HEDP: isigubhu seplastiki esingu-200L, i-IBC (1000L), isidingo samakhasimende.

I-HEDP solid: 25kg / isikhwama, izidingo zamakhasimende.

Isitoreji izinyanga eziyishumi nambili egumbini elinomthunzi nendawo eyomile.
