I-HEDP Yokuhlinzeka Ngemboni evela e-China CAS:2809-21-4 enekhwalithi ephezulu
Izakhiwo
I-HEDP iyi-organophosphoric acid corrosion inhibitor. Ingakwazi ukuxubha nge-Fe, Cu, kanye ne-Zn ions ukwenza izinhlanganisela ezizinzile ze-chelating. Ingancibilikisa izinto ezenziwe nge-oxidized ezindaweni zalezi zinsimbi.
I-HEDP ibonisa isikali esihle kakhulu kanye nemiphumela yokuvimbela ukugqwala ngaphansi kwezinga lokushisa elingu-250°C.
I-HEDP inokusimama 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, ibonisa imiphumela emihle ye-synergistic.

Ukusetshenziswa Kwemikhiqizo
1. I-HEDP (Cas No 2809-21-4) I-Corrosion Inhibitor isetshenziswa njenge-scale and corrosion inhibition ohlelweni lwamanzi ajikelezayo, insimu kawoyela kanye nama-boilers anengcindezi ephansi emikhakheni efana namandla kagesi, imboni yamakhemikhali, i-metallurgy, umanyolo, njll.
2. Embonini eyalukiwe elula, i-HEDP (Cas No 2809-21-4) I-Corrosion Inhibitor isetshenziswa njengesihlanzi sensimbi nesingeyona insimbi.
3. Embonini yokudaya, i-HEDP (Cas No 2809-21-4) I-Corrosion Inhibitor isetshenziswa njenge-peroxide stabilizer kanye ne-ejenti yokulungisa udayi.
4. Ku-non-cyanide electroplating, i-HEDP (Cas No 2809-21-4) Corrosion Inhibitor isetshenziswa njenge-chelating agent.Umthamo we-1-10mg/L ukhethwa njenge-scale inhibitor, 10-50mg/L njenge-corrosion inhibitor, futhi 1000-2000mg/L njengesihlanzi.
Ngokuvamile, i-HEDP (Cas No 2809-21-4) Corrosion Inhibitor isetshenziswa kanye ne-polycarboxylic acid.
Iphakheji Nesitoreji
Uketshezi lwe-ATMP:200L isigubhu sepulasitiki, i-IBC(1000L), imfuneko yamakhasimende.
Isitoreji izinyanga eziyi-12 egumbini elinomthunzi nasendaweni eyomile.
