I-Alloy Enganyangekiyo NokugqwalaIMonel 400Umbhobho we-Alloy weNickel ojikelezileyo

Inkcazo
I-Monel 400 (UNS N04400/2.4360) yi-alloy ye-nickel-copper enamandla aphezulu kunye nokumelana okuhle kakhulu kwiindidi ezahlukeneyo zeendaba eziquka amanzi olwandle, i-dilute hydrofluoric kunye ne-sulfuric acids, kunye ne-alkalies.
I-Monel 400 equlethe malunga ne-30-33% yobhedu kwi-nickel matrix ineempawu ezininzi ezifanayo ze-nickel ecocekileyo yorhwebo, ngelixa iphucuka kunezinye ezininzi. Ukongezwa kwesinyithi kuphucula kakhulu ukumelana nokuqhekeka kwe-cavitation kunye nokukhukuliseka kwizicelo zeetyhubhu ze-condenser. Ukusetyenziswa okuphambili kwe-Monel 400 kuphantsi kweemeko zesantya esiphezulu sokuhamba kunye nokukhukuliseka njengakwi-propeller shafts, ii-propellers, ii-pump-impeller blades, ii-casings, ii-condenser tubes, kunye neetyhubhu ze-heat exchanger. Izinga lokukhukuliseka emanzini olwandle ahambayo ngokubanzi lingaphantsi kwe-0.025 mm ngonyaka. I-alloy inokufaka emanzini olwandle angashukumiyo, nangona kunjalo, izinga lokuhlaselwa liphantsi kakhulu kune-alloy ecocekileyo yorhwebo 200. Ngenxa yomxholo wayo ophezulu we-nickel (malunga ne-65%) i-alloy ngokubanzi ayichaphazeleki kukuqhekeka kwe-chloride stress corrosion. Ukuxhathisa ukukhukuliseka ngokubanzi kwe-Monel 400 kwi-nonoxidizing mineral acids kungcono xa kuthelekiswa ne-nickel. Nangona kunjalo, inengxaki efanayo yobuthathaka bokubonisa ukumelana nokugqwala okubi kakhulu kwi-oxidizing media ezifana ne-ferric chloride, i-cupric chloride, i-chlorine emanzi, i-chromic acid, i-sulfur dioxide, okanye i-ammonia. Kwisisombululo se-hydrochloric kunye ne-sulfuric acid esingafakwanga i-unaerated, i-alloy inokumelana okuluncedo ukuya kuthi ga kwi-15% kubushushu begumbi kunye nokuya kuthi ga kwi-2% kubushushu obuphezulu kancinci, obungadluli kwi-50°C. Ngenxa yolu phawu luthile, i-Monel 400 eveliswa yi-NiWire ikwasetyenziswa kwiinkqubo apho izinyibilikisi ze-chlorine zinokwenza i-hydrochloric acid ngenxa ye-hydrolysis, enokubangela ukungaphumeleli kwintsimbi engagqwaliyo eqhelekileyo.
I-Monel 400 inokumelana okuhle nokugqwala kumaqondo obushushu aphakathi kuyo yonke i-HF xa kungekho moya. Izisombululo ezivuthelweyo kunye nobushushu obuphezulu ziyandisa izinga lokugqwala. I-alloy ichaphazeleka lula kukuqhekeka kokugqwala koxinzelelo kumphunga we-hydrofluoric okanye i-hydrofluorosilic acid omanzi. Oku kungancitshiswa ngokuncitshiswa kweendawo ezingqongileyo okanye ngokunciphisa uxinzelelo lwenxalenye ekuthethwa ngayo.
Izinto ezisetyenziswa rhoqo ziinxalenye zevalvu kunye neepompo, iishafts zepropeller, izixhobo zolwandle kunye nezibophelelo, izinto ze-elektroniki, izixhobo zokucubungula iikhemikhali, iitanki zepetroli namanzi acocekileyo, izixhobo zokucubungula ipetroli, izifudumezi zamanzi ebhoyila kunye nezinye izinto zokutshintsha ubushushu.
