Ngaphambi kokuqonda ukuthi singayibona kanjani futhi siyikhethe kanjani impahla ye-CuNi44, sidinga ukuqonda ukuthi iyini i-copper-nickel 44 (CuNi44). I-Copper-nickel 44 (CuNi44) iyinto eyenziwe nge-alloy yethusi-nickel. Njengoba igama layo lisikisela, ithusi lingenye yezingxenye eziyinhloko ze-alloy. I-Nickel nayo ingenye yezingxenye eziyinhloko, enokuqukethwe okungu-43.0% - 45.0%. Ukwengezwa kwe-nickel kungathuthukisa amandla, ukumelana nokugqwala, ukumelana kanye nezakhiwo ze-thermoelectric ze-alloy. Ngaphezu kwalokho, ifaka phakathi kodwa ayikhawulelwe ku-0.5% - 2.0% manganese. Ukuba khona kwe-manganese kusiza ukuthuthukisa ukumelana nokugqwala, ukuzinza kokushisa kanye namandla e-alloy, kodwa i-manganese eningi ingabangela ubuthakathaka.
I-Copper-nickel 44 inokumelana okuphansi kwezinga lokushisa, futhi ukumelana kwayo kuzinzile uma izinga lokushisa lishintsha, okwenza kube usizo ekusetshenzisweni lapho kudingeka khona ukuzinza kokumelana. Uma icindezelwa futhi iguquguquka, isizathu sokuthi i-copper-nickel 44 ingagcina ukusebenza okuzinzile ukuthi i-coefficient yayo yokuzwela kokucindezeleka ayishintshi kakhulu ngesikhathi sokucindezeleka kwepulasitiki futhi i-hysteresis yemishini incane. Ngaphezu kwalokho, i-CuNi44 inamandla amakhulu okushisa i-copper, inokusebenza okuhle kokushisela, futhi ilungele ukucutshungulwa nokuxhumeka.
Ngenxa yezakhiwo zayo ezinhle zikagesi nezemishini, i-CuNi44 ivame ukusetshenziselwa ukukhiqiza izingxenye ezahlukene ze-elekthronikhi ezifana nama-resistor, ama-potentiometer, ama-thermocouple, njll., isibonelo, njengengxenye ebalulekile kumathuluzi kagesi anembile. Emkhakheni wezimboni, ingasetshenziswa ukukhiqiza amabhokisi okumelana nezimboni anemithwalo ephezulu, ama-rheostat kanye neminye imishini. Ngenxa yokumelana kwayo okuhle nokugqwala, ifaneleka futhi ezindaweni ezinezidingo eziphezulu zokumelana nokugqwala njengemishini yamakhemikhali kanye nezingxenye zemikhumbi.
Uma sithenga imikhiqizo, sizibona kanjani izinto ze-CuNi44? Nazi izindlela ezintathu zokuhlonza ongazisebenzisa ukuze ubhekisele kuzo.
Okokuqala, indlela enembile kakhulu ukusebenzisa imishini yokuhlaziya amakhemikhali yobungcweti.Njenge-spectrometer, njll., ukuhlola ukwakheka kwezinto. Qinisekisa ukuthi okuqukethwe kwethusi kusele, okuqukethwe yi-nickel kungu-43.0% - 45.0%, okuqukethwe kwensimbi kungu-≤0.5%, okuqukethwe yi-manganese kungu-0.5% - 2.0%, kanti ezinye izinto zingaphakathi kobubanzi obubekiwe. Uma amakhasimende ethu ethenga imikhiqizo ye-tankii, singabanikeza isitifiketi sekhwalithi noma umbiko wokuhlola wezinto.
Okwesibili, mane nje ukhombe futhi uhlole izici zokubukeka komkhiqizo.Izinto ze-CuNi44 zivame ukuveza ukukhanya kwensimbi, futhi umbala ungaba phakathi kwethusi ne-nickel. Bheka ukuthi ubuso bezinto bubushelelezi yini, abunazo iziphambeko ezisobala, ukugqwala noma ukugqwala.
Indlela yokugcina ukuhlola izakhiwo zomzimba zomkhiqizo - ukukala ubuningi kanye nokuqina kwezinto.I-CuNi44inebanga elithile lobuningi, elingahlolwa ngamathuluzi okulinganisa ubuningi obuchwepheshile futhi liqhathaniswe nenani elijwayelekile. Lingalinganiswa futhi ngomhloli wobunzima ukuze kuqondwe ukuthi ubulukhuni balo buhlangabezana yini nobubanzi obujwayelekile bobulukhuni be-copper-nickel 44.
Imakethe inkulu kakhulu, ungakhetha kanjani umhlinzeki ohlangabezana nezidingo zethu zokuthenga?
Ngesikhathi sophenyo, amakhasimende kudingeka acacise izidingo zokusebenzisa.Isibonelo: nquma ukusetshenziswa okuthile kwezinto. Uma isetshenziselwa ukukhiqizwa kwezingxenye ze-elekthronikhi, izakhiwo zayo zikagesi, njenge-coefficient yokumelana okuphansi kanye nokusebenza kahle kokushisela, kudingeka kucatshangelwe; uma isetshenziselwa imishini yamakhemikhali noma izingxenye zemikhumbi, ukumelana kwayo nokugqwala kubaluleke kakhulu. Uma ihlanganiswe nokusetshenziswa kwe-terminal, izinga lokushisa, ingcindezi, ukugqwala kanye nezinye izici zendawo yokusetshenziswa ziyacatshangelwa ukuqinisekisa ukuthi i-CuNi44 esiyithengayo ingasebenza ngokujwayelekile ngaphansi kwalezi zimo.
Ngaphezu kwalokho, phakathi nesikhathi sophenyo, ungahlola umhlinzeki ngokuhlola isitifiketi sokufaneleka komhlinzeki, ukuhlolwa kwamakhasimende, idumela lemboni, njll. Ungacela futhi umhlinzeki ngokuqondile ukuthi anikeze isiqinisekiso sekhwalithi yezinto ezibonakalayo kanye nemibiko yokuhlola ukuqinisekisa ukuthi ikhwalithi yezinto ezibonakalayo ithembekile.
Ngaphezu kwamaphuzu amabili angenhla, ukulawula izindleko nakho kubalulekile.Kudingeka siqhathanise amanani abaphakeli abahlukene. Vele, asikwazi ukusebenzisa intengo njengesici sokukhetha kuphela. Kubalulekile ngokulinganayo ukucabangela izici ezifana nekhwalithi yezinto ezibonakalayo, ukusebenza kanye nensizakalo yangemva kokuthengisa. Isikhathi senkonzo yezinto ezibonakalayo sihlobene ngqo nezindleko zokulungisa. Izinto ze-CuNi44 ezisezingeni eliphezulu zingase zibe nezindleko zokuqala eziphakeme, kodwa zingonga izindleko zokulungisa nezokufaka esikhundleni sazo ekusetshenzisweni kwesikhathi eside.
Okokugcina, kufanelekile ukusho ukuthi ngaphambi kokuthenga imikhiqizo ngezinga elikhulu, ungacela umhlinzeki amasampula okuhlolwa. Hlola ukuthi ukusebenza kwezinto kuyahlangabezana yini nezidingo, njengezakhiwo zikagesi, ukumelana nokugqwala, izakhiwo zemishini, njll. Ngokusekelwe emiphumeleni yokuhlolwa, nquma ukuthi ukhetha yiniithusi-nickel 44izinto zomhlinzeki.
