1. Izithako Ezihlukile

Ingxubevange ye-chromium ye-nickelIntambo yakhiwe kakhulu yi-nickel (Ni) kanye ne-chromium (Cr), futhi ingaqukatha nezinye izakhi ezincane. Okuqukethwe yi-nickel ku-nickel-chromium alloy ngokuvamile kungaba ngu-60%-85%, kanti okuqukethwe yi-chromium kungaba ngu-10%-25%. Isibonelo, i-nickel-chromium alloy evamile i-Cr20Ni80 inokuqukethwe kwe-chromium okungaba ngu-20% kanye nokuqukethwe kwe-nickel okungaba ngu-80%.

Ingxenye eyinhloko yocingo lwethusi yithusi (Cu), okumsulwa kwalo kungafinyelela ngaphezu kwama-99.9%, njengethusi elihlanzekile le-T1, okuqukethwe kwethusi kufikela kuma-99.95%.

2. Izakhiwo Ezihlukile Zomzimba

Umbala

- Intambo ye-Nichrome ivame ukuba ngwevu ngesiliva. Lokhu kungenxa yokuthi ukukhanya kwensimbi kwe-nickel ne-chromium kuxutshwe ukuze kunikezwe lo mbala.

- Umbala wentambo yethusi ubomvu onsomi, okuwumbala ojwayelekile wethusi futhi unokukhanya kwensimbi.

Ubuningi

- Ubuningi obuqondile be-nickel-chromium alloy bukhulu kakhulu, ngokuvamile bungaba ngu-8.4g/cm³. Isibonelo, imitha eyi-cubic meter eyodwa yocingo lwe-nichrome inesisindo esingaba ngu-8400 kg.

- Iucingo lwethusiubuningi bungaba ngu-8.96g/cm³, futhi ivolumu efanayo yentambo yethusi inzima kancane kunentambo ye-nickel-chromium alloy.

Indawo Yokuncibilika

I-alloy ye-Nickel-chromium inezinga lokuncibilika eliphezulu, cishe ngo-1400 ° C, okwenza ikwazi ukusebenza emazingeni okushisa aphezulu ngaphandle kokuncibilika kalula.

-Iphuzu lokuncibilika kwethusi licishe libe ngu-1083.4℃, elingaphansi kunele-nickel-chromium alloy.

Ukuqhuba Kagesi

-Intambo yethusi iqhuba ugesi kahle kakhulu, esimweni esijwayelekile, ithusi linokuqhuba kukagesi okungaba ngu-5.96×10 guess S/m. Lokhu kungenxa yokuthi isakhiwo se-elekthronikhi sama-athomu ethusi siyayivumela ukuthi iqhube kahle ugesi, futhi iyinto evame ukusetshenziswa kakhulu, esetshenziswa kabanzi emikhakheni efana nokudlulisa amandla.

Intambo ye-alloy ye-nickel-chromium ine-conductivity kagesi ephansi, futhi i-conductivity yayo kagesi iphansi kakhulu kuneyethusi, cishe i-1.1×10⁶S/m. Lokhu kungenxa yesakhiwo se-athomu kanye nokusebenzisana kwe-nickel ne-chromium ku-alloy, okwenza ukuqhutshwa kwama-electron kuphazamiseke ngezinga elithile.

Ukuqhuba kwe-thermal

-Ithusi linomoya omuhle kakhulu wokushisa, kanye nomoya wokushisa ongaba ngu-401W/(m·K), okwenza ithusi lisetshenziswe kabanzi ezindaweni lapho kudingeka khona umoya omuhle wokushisa, njengamadivayisi okususa ukushisa.

Ukushisa kwe-nickel-chromium alloy kubuthakathaka kakhulu, kanti ukushisa ngokuvamile kuphakathi kuka-11.3 no-17.4W/(m·K)

3. Izakhiwo Ezihlukahlukene Zamakhemikhali

Ukumelana Nokugqwala

Ama-alloy e-nickel-chromium anokumelana okuhle nokugqwala, ikakhulukazi ezindaweni zokushisa okuphezulu. I-nickel ne-chromium zakha ifilimu ye-oxide eningi ebusweni be-alloy, okuvimbela ukusabela okuqhubekayo kwe-oxidation. Isibonelo, emoyeni okushisa okuphezulu, lolu ngqimba lwefilimu ye-oxide lungavikela insimbi engaphakathi kwe-alloy ekugqwaleni okuqhubekayo.

- Ithusi lifakwa kalula emoyeni ukuze lakhe i-vercas (i-carbonate yethusi eyisisekelo, ifomula i-Cu₂(OH)₂CO₃). Ikakhulukazi endaweni enomswakama, ubuso bethusi buzogqwala kancane kancane, kodwa ukumelana kwalo nokugqwala kwamanye ama-asidi angagqwali kuhle kakhulu.

Ukuzinza Kwamakhemikhali

- I-Nichrome alloy inamandla aphezulu okuqina kwamakhemikhali futhi ingahlala izinzile lapho kukhona amakhemikhali amaningi. Inokubekezelela okuthile kuma-asidi, izisekelo kanye namanye amakhemikhali, kodwa ingasabela futhi kuma-asidi aqinile oxidizing.

- Ithusi kwamanye ama-oxidants aqinile (njenge-nitric acid) ngaphansi kwesenzo sokusabela kwamakhemikhali okunamandla kakhulu, i-reaction equation ingu-\(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Ukusetshenziswa Okuhlukile

- ucingo lwe-alloy lwe-nickel-chromium

- Ngenxa yokumelana kwayo okuphezulu kanye nokumelana nokushisa okuphezulu, isetshenziswa kakhulu ekwenzeni izinto zokushisa zikagesi, njengezintambo zokushisa kuma-oven kagesi kanye nezifudumezi zamanzi zikagesi. Kula madivayisi, izintambo ze-nichrome ziyakwazi ukuguqula amandla kagesi abe ukushisa ngempumelelo.

- Iphinde isetshenziswe kwezinye izikhathi lapho izakhiwo zemishini zidinga ukugcinwa ezindaweni ezinokushisa okuphezulu, njengezingxenye ezisekelayo zezitofu ezinokushisa okuphezulu.

- Ucingo lwethusi

- Intambo yethusi isetshenziswa kakhulu ekudluliseni ugesi, ngoba ukuhanjiswa kwayo okuhle kukagesi kunganciphisa ukulahleka kwamandla kagesi ngesikhathi sokudlulisa. Ohlelweni lwegridi yamandla, inani elikhulu lezintambo zethusi lisetshenziselwa ukwenza izintambo nezintambo.

- Iphinde isetshenziswe ukwenza ukuxhumana kwezingxenye ze-elekthronikhi. Emikhiqizweni ye-elekthronikhi efana namakhompyutha kanye namaselula, izintambo zethusi zingadlulisa isignali kanye nokunikezwa kwamandla phakathi kwezingxenye ze-elekthronikhi ezahlukahlukene.
