Ingxubevange Emelana NokugqwalaI-Monel 400Ipayipi le-Nickel Alloy eliyindilinga

Incazelo
I-Monel 400 (UNS N04400/2.4360) iyi-alloy ye-nickel-copper enamandla aphezulu kanye nokumelana okuhle kakhulu nezinhlobo ezahlukene zemidiya okuhlanganisa amanzi olwandle, ama-hydrofluoric kanye nama-sulfuric acid ancibilikisiwe, kanye nama-alkali.
I-Monel 400 equkethe cishe ithusi elingu-30-33% ku-nickel matrix inezici eziningi ezifanayo ze-nickel emsulwa ethengiswayo, kuyilapho ithuthuka kunezinye eziningi. Ukwengezwa kwensimbi ethile kuthuthukisa kakhulu ukumelana nokuvuvukala kanye nokuguguleka kwe-cavitation ekusetshenzisweni kwe-condenser tube. Ukusetshenziswa okuyinhloko kwe-Monel 400 kungaphansi kwezimo zesivinini esikhulu sokugeleza kanye nokuguguleka njengakuma-propeller shafts, ama-propeller, ama-pump-impeller blades, ama-casings, ama-condenser tubes, kanye nama-heat exchanger tubes. Izinga lokugqwala emanzini olwandle ahambayo ngokuvamile lingaphansi kuka-0.025 mm/ngonyaka. I-alloy ingangena emanzini olwandle amile, nokho, izinga lokuhlasela liphansi kakhulu kune-alloy emsulwa ethengiswayo engu-200. Ngenxa yokuqukethwe kwayo okuphezulu kwe-nickel (cishe u-65%) i-alloy ngokuvamile ayivikelekile ekuqhekekeni kwe-chloride stress corrosion. Ukumelana nokugqwala okuvamile kwe-Monel 400 kuma-mineral acids angangcolisi kungcono uma kuqhathaniswa ne-nickel. Kodwa-ke, ihlushwa ubuthakathaka obufanayo bokubonisa ukumelana nokugqwala okubi kakhulu nemidiya yokuxova njenge-ferric chloride, i-cupric chloride, i-wet chlorine, i-chromic acid, i-sulfur dioxide, noma i-ammonia. Esixazululweni se-hydrochloric ne-sulfuric acid esingafakwanga kahle, i-alloy inokumelana okuwusizo okufika ku-15% ekushiseni kwegumbi kanye nokufika ku-2% ekushiseni okuphezulu kancane, okungadluli ku-50°C. Ngenxa yalesi sici esithile, i-Monel 400 ekhiqizwa yi-NiWire nayo isetshenziswa ezinqubweni lapho izinyibilikisi ezine-chlorine zingakha i-hydrochloric acid ngenxa ye-hydrolysis, okungabangela ukwehluleka kwensimbi engagqwali ejwayelekile.
I-Monel 400 inokumelana okuhle kokugqwala emazingeni okushisa aseduze nawo wonke amazinga e-HF uma kungekho moya. Izixazululo ezivuvukele kanye nokushisa okuphezulu kwandisa izinga lokugqwala. Ingxube isengozini yokuqhekeka kokugqwala kokucindezeleka emphefumulweni we-hydrofluoric noma we-hydrofluorosilic acid omanzi. Lokhu kungancishiswa ngokuncishiswa kwendawo noma ngokunciphisa ukucindezeleka kwengxenye okukhulunywa ngayo.
Izicelo ezijwayelekile yizingxenye zamavalvu nezamaphampu, imiphini yepropeller, izinto zokufakelwa zasolwandle kanye nezinamathiselo, izingxenye ze-elekthronikhi, imishini yokucubungula amakhemikhali, amathangi kaphethiloli namanzi ahlanzekile, imishini yokucubungula uphethiloli, izifudumezi zamanzi okuhambisa amanzi ebhoyila kanye nezinye izinto zokushintshanisa ukushisa
