I-Hastelloy C-276® ingxubevange ye-nickel-molybdenum-chromium enokumelana nokugqwala okuhle kakhulu ezindaweni ezinzima.Okuqukethwe okuphezulu kwe-nickel ne-molybdenum kwenza ingxubevange yensimbi ye-nickel imelane ikakhulukazi ne-pitting kanye nokugqwala kwe-crevice ezindaweni ezinciphisayo kuyilapho i-chromium idlulisa ukumelana nemidiya ye-oxidizing.Nakuba kunezinhlobonhlobo eziningana ze-Hastelloy nickel alloy, i-Hastelloy C-276 iyona esetshenziswa kakhulu kunazo zonke.
Uhlolojikelele lwezimpawu ze-Hastelloy C-276:
I-Hastelloy C-276 (N10276) inokumelana okuhle kakhulu nokugqwala emithonjeni eminingi egqwalayo ngaphansi kwezimo ze-oxidation nokunciphisa.Ukumelana okuhle kakhulu nokugqwala kwe-pitting, ukugqwala kwe-crevice kanye nokuqhekeka kokugqwala kwengcindezi.I-alloy ifanele izimboni ezihlukahlukene zezinqubo zamakhemikhali eziqukethe i-oxidizing nokunciphisa imidiya.Okuqukethwe okuphezulu kwe-molybdenum ne-chromium kwenza ingxubevange imelane nokugqwala ngama-ion e-chloride, futhi isici se-tungsten sithuthukisa ngokwengeziwe ukumelana nokugqwala.
I-Hastelloy C-276 ingenye yezinto kuphela ezingamelana nokugqwala kwe-chlorine emanzi, i-hypochlorite nesisombululo se-chlorine dioxide.Ingxubevange inokumelana nokugqwala okubalulekile ekuxazululeni usawoti we-chlorine ogxilile kakhulu (njenge-Iron chlorinated ne-copper chloride).

Izicelo ze-Hastelloy C276®
I-Hastelloy C-276 isetshenziswe kabanzi emkhakheni wamakhemikhali kanye ne-petrochemical, njengasezingxenyeni nasezinhlelweni ze-catalytic ezithinta izinto eziphilayo ezine-chloride.Le nto ifaneleka ngokukhethekile ukusetshenziswa ekushiseni okuphezulu, okuxutshwe nokungcola kwama-asidi angaphili ne-organic (njenge-formic acid ne-acetic acid), kanye nezindawo ezidla amanzi olwandle.
Ezinye izindawo zokufaka isicelo:
● Imboni ye-pulp nephepha, njengokugayeka kokudla kanye nemikhumbi yokuhlanza
●Umbhoshongo wokuwasha, i-heater, ifeni yesitimu esimanzi, njll. ohlelweni lwe-FGD
●Izisetshenziswa nezingxenye ezisebenza endaweni yegesi ene-asidi
●I-reactor ye-acetic acid nemikhiqizo ye-asidi
● I-condenser ye-sulfuric acid
●I-Methylene diphenyl isocyanate (MDI)
● Ukukhiqizwa nokucutshungulwa kwe-phosphoric acid engcolile
