Ukuxuba ithusi ne-nickel kudala umndeni wama-alloy aziwa ngokuthi ama-alloy e-copper-nickel (Cu-Ni), ahlanganisa izakhiwo ezinhle kakhulu zezinsimbi zombili ukuze zakhe into enezici zokusebenza ezivelele. Lokhu kuhlanganiswa kuguqula izici zazo ngazinye zibe yisethi yezinzuzo ezihambisanayo, okwenzaAma-alloy e-Cu-Niibaluleke kakhulu ezinhlotsheni ezahlukene zezimboni—futhi imikhiqizo yethu ye-Cu-Ni yenzelwe ukukhulisa lezi zinzuzo.
Ezingeni lama-molecule, ithusi ne-nickel kwakha isixazululo esiqinile uma kuxutshwe, okusho ukuthi ama-athomu ezinsimbi zombili asatshalaliswa ngokulinganayo kuyo yonke into. Lokhu kufana kuyisihluthulelo sezakhiwo zawo ezithuthukisiwe. Ithusi elimsulwa linamandla okuhambisa umoya futhi liyaguquguquka kodwa alinawo amandla okumelana nokugqwala, kuyilapho i-nickel iqinile futhi imelana nokugqwala kodwa ayihambisani kahle. Ndawonye, zakha into elinganisela lezi zimpawu.
Omunye wemiphumela ebaluleke kakhulu yale nhlanganisela ukumelana nokugqwala okuphezulu. Okuqukethwe kwe-nickel kuma-alloy e-Cu-Ni kwakha ungqimba lwe-oxide oluqinile noluvikelayo ebusweni, oluvikela izinto emanzini anosawoti, ama-acid, kanye namakhemikhali ezimboni. Lokhu kwenza ama-alloy e-Cu-Ni afanelekele izindawo zasolwandle, njengemikhumbi yemikhumbi, amapayipi amanzi olwandle, kanye namapulatifomu asogwini lolwandle, lapho ithusi elimsulwa lingagqwala khona ngokushesha. Imikhiqizo yethu ye-Cu-Ni, eyenzelwe lezi zindawo ezinzima, imelana nokugqwala, ukugqwala kwemifantu, kanye nokuguguleka, okuqinisekisa ukuqina kwesikhathi eside.
Amandla emishini nawo athola ukukhushulwa yinhlanganisela yethusi ne-nickel. Ama-alloy e-Cu-Ni aqinile futhi aqinile kunethusi elimsulwa, kuyilapho egcina ukuguquguquka okuhle. Lokhu kuwavumela ukuthi amelane nokucindezeleka okukhulu kwemishini ezisetshenziswayo njengezipompo, ama-valve, kanye nama-heat exchanger. Ngokungafani nethusi elimsulwa, elingawohloka ngaphansi kwemithwalo esindayo, izintambo namashidi ethu e-Cu-Ni agcina ubuqotho besakhiwo ngisho nasezimweni ezinzima, okunciphisa izidingo zokulungisa.
Ukushisa kanye nokushisa kukagesi kuhlala kumangalisa kuma-alloy e-Cu-Ni, yize kuphansi kancane kunethusi elihlanzekile. Lokhu kuzenza zifaneleke kuma-heat exchanger kanye nezingxenye zikagesi lapho ukumelana nokugqwala kubaluleke kakhulu njengokushisa. Isibonelo, ezitshalweni zokususa usawoti emanzini, amashubhu ethu e-Cu-Ni adlulisa ukushisa ngempumelelo ngenkathi emelana nemiphumela yokugqwala kwamanzi anosawoti.
Imikhiqizo yethu ye-Cu-Ni itholakala ngezinhlobo ezahlukene, okuqukethwe yi-nickel kusuka ku-10% kuya ku-30%,eklanyelwe izidingo ezithile zohlelo lokusebenza. Kungakhathaliseki ukuthi udinga izintambo ezincane zezingxenye eziyinkimbinkimbi noma amashidi aqinile ezakhiwo ezisindayo, ukukhiqizwa kwethu okunembile kuqinisekisa ikhwalithi nokusebenza okulinganayo. Ngokusebenzisa izinzuzo eziyingqayizivele zokuxuba ithusi ne-nickel, imikhiqizo yethu iletha ukuthembeka nokuphila isikhathi eside ezindaweni lapho izinsimbi ezihlanzekile zingaphumeleli khona.
