I-NiCu 400 iyingxubevange ye-nickel-copper (cishe i-67% Ni - 23% Cu) ekwazi ukumelana namanzi olwandle kanye nesimusi emazingeni okushisa aphezulu kanye nosawoti kanye nezixazululo ze-caustic. I-alloy 400 iyingxube yesisombululo esiqinile esingaqiniswa kuphela ngokusebenza okubandayo. Le nickel alloy ikhombisa izici ezinjengokumelana nokugqwala okuhle, ikhono elihle lokushisela namandla aphezulu. Izinga lokugqwala eliphansi emanzini anosawoti agelezayo noma olwandle ahlanganiswe nokumelana okuhle nokuqhekeka kwe-stress-corrosion emanzini amaningi ahlanzekile, kanye nokumelana kwawo nezimo ezigqwala ezihlukahlukene kuholele ekusetshenzisweni kwawo okubanzi ekusetshenzisweni olwandle nezinye izixazululo ze-chloride ezingaxubeki. Le ingxubevange ye-nickel imelana ikakhulukazi ne-hydro-chloric kanye ne-hydro-fluoric acid lapho i-deaerated. Njengoba kulindelekile kokuqukethwe kwayo kwethusi okuphezulu, ingxubevange engu-400 ihlaselwa ngokushesha yi-nitric acid nezinhlelo ze-ammonia.
I-NiCu 400 inezici ezinhle zemishini emazingeni okushisa angaphansi kwe-subzero, ingasetshenziswa emazingeni okushisa afika ku-1000 ° F, futhi iphuzu layo lokuncibilika liyi-2370-2460 ° F. Nokho, i-Alloy 400 inamandla aphansi esimweni sokuthukuthela ngakho-ke, ukufutheka okuhlukahlukene ingasetshenziswa ukwandisa amandla.
Izimpawu ze-NiCu 400
- Imelana namanzi olwandle kanye nesitimu emazingeni okushisa aphezulu
- Ukumelana okuhle kakhulu emanzini anosawoti agelezayo noma amanzi olwandle
- Ukumelana okuhle kakhulu nokuqhekeka kokugqwala kwengcindezi emanzini amaningi ahlanzekile
- Imelana kakhulu ne-hydro-chloric kanye ne-hydro-fluoric acid lapho i-deaerated
- Ukumelana okuhle kakhulu nosawoti ongathathi hlangothi kanye ne-alkaline nokumelana okuphezulu kwama-alkali
- Ukumelana nokuqhekeka kokugqwala kwe-chloride
- Izakhiwo ezinhle zikagesi ezisuka emazingeni okushisa angaphansi kukaziro afika ku-1020° F
- Inikeza ukumelana okuthile ne-hydro-chloric kanye ne-sulfuric acid emazingeni okushisa anesizotha nokugxila, kodwa akuvamile ukuba ibe yimpahla ekhethwayo kulawa ma-asidi.
Le ngxubevange inomlando omude wokusetshenziswa njengento ekwazi ukumelana nokugqwala, esukela ekuqaleni kwekhulu lama-20 lapho ithuthukiswa njengomzamo wokusebenzisa i-nickel ore yokuqukethwe kwethusi okuphezulu. Okuqukethwe kwe-nickel nethusi kwe-ore bekukusilinganiso esilinganiselwe manje esishiwo ngokusemthethweni ku-alloy.

I-NiCu 400 Engavimbeli Ukugqwala
I-NiCu Alloy 400icishe ivikeleke ekuqhekekeni kwe-chloride ion stress corrosion ezindaweni ezijwayelekile. Ngokuvamile, ukumelana nokugqwala kwayo kuhle kakhulu ekunciphiseni izindawo, kodwa kubi kakhulu ezimweni ze-oxidizing. Ayiwusizo kuma-asidi oxidizing, njenge-nitric acid ne-nitrous. Noma kunjalo, imelana nama-alkali amaningi, usawoti, amanzi, imikhiqizo yokudla, izinto eziphilayo nezimo zomkhathi emazingeni okushisa avamile naphakeme.
Le nickel alloy ihlaselwa ngamagesi anesulfure angaphezu kuka-700° F futhi isibabule esincibilikisiwe sihlasela ingxubevange emazingeni okushisa angaphezu kuka-500° F.
I-NiCu 400 inikeza mayelana nokumelana nokugqwala okufanayo njenge-nickel kodwa enezingcindezi eziphezulu zokusebenza eziphezulu namazinga okushisa futhi ngezindleko eziphansi ngenxa yekhono layo eliphezulu lokwenziwa ngomshini.
Izicelo ze-NiCu 400
- Ubunjiniyela basolwandle
- Imishini yokucubungula amakhemikhali ne-hydrocarbon
- Amathangi kaphethiloli namanzi ahlanzekile
- I-petroleum stills engahluziwe
- Ama-heaters asusa umoya
- Ama-heaters amanzi okuphakelayo kanye nezinye izishintshi zokushisa
- Amavalvu, amaphampu, amashafti, okokufakwayo, nezixhumi
- Izishintshi zokushisa zezimboni
- Ama-solvents ane-chlorine
- Imibhoshongo yokugcwalisa uwoyela ongahluziwe
I-NiCu 400 Fabrication
I-NiCu Alloy 400 ingashiselwa kalula nge-gas-tungsten arc, i-gas metal arc noma izinqubo ze-arc zensimbi ezivikelekile zisebenzisa izinsimbi zokugcwalisa ezifanele. Asikho isidingo sokwelashwa kokushisa kwe-post weld, noma kunjalo, ukuhlanzwa okuphelele ngemuva kokushisela kubalulekile ekumelaneni nokugqwala okukhulu, ngaphandle kwalokho kunengozi yokungcola kanye ne-embrittlement.
Ukwakhiwa okuqediwe kungakhiqizwa ezinhlobonhlobo zezakhiwo zemishini lapho kulawulwa kahle inani lokusebenza okushisayo noma okubandayo kanye nokukhethwa kokwelashwa okushisayo okufanelekile kwenziwa.
Njengamanye ama-nickel alloys amaningi, i-NiCu 400 ivamise ukuba nzima emshinini futhi izosebenza kanzima. Kodwa-ke, imiphumela emihle kakhulu ingatholwa uma wenza ukukhetha okulungile kokusebenza kwamathuluzi kanye nokwenza imishini.
