1.Izithako Ezihlukene

Ingxube ye-nickel chromiumucingo ngokuyinhloko lwakhiwe i-nickel (Ni) ne-chromium (Cr), futhi ingase iqukathe amanani amancane ezinye izakhi. Okuqukethwe kwe-nickel ku-nickel-chromium alloy ngokuvamile cishe ku-60% -85%, futhi okuqukethwe kwe-chromium cishe ku-10% -25%. Isibonelo, ingxubevange evamile ye-nickel-chromium Cr20Ni80 inokuqukethwe kwe-chromium okungaba ngu-20% nokuqukethwe kwe-nickel okungaba ngu-80%.

Ingxenye eyinhloko yocingo lwethusi ithusi (Cu), ubumsulwa bayo bungafinyelela ngaphezu kuka-99.9%, njenge-T1 yethusi ehlanzekile, okuqukethwe kwethusi okuphezulu njengo-99.95%.

2.Izakhiwo Ezihlukile Zomzimba

Umbala

- I-Nichrome wire ngokuvamile i-silver gray. Lokhu kungenxa yokuthi i-metallic luster ye-nickel ne-chromium ixutshwe ukunikeza lo mbala.

- Umbala wentambo yethusi unombala onsomi onsomi, okuwumbala ojwayelekile wethusi futhi unokucwebezela kwensimbi.

Ukuminyana

- Ukuminyana komugqa we-nickel-chromium alloy likhulu ngokuqhathaniswa, ngokuvamile lilinganiselwa ku-8.4g/cm³. Isibonelo, i-cubic meter yocingo lwe-nichrome inesisindo esingaba ngu-8400 kg.

- Theucingo lwethusiukuminyana cishe ku-8.96g/cm³, futhi ivolomu efanayo yocingo lwethusi isinda kancane kunocingo lwe-nickel-chromium alloy.

I-Melting Point

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

-Indawo yokuncibilika yethusi icishe ibe ngu-1083.4℃, ephansi kunaleyo ye-nickel-chromium alloy.

I-Electric Conductivity

-I-Copper wire iqhuba ugesi kahle kakhulu, esimweni esivamile, ithusi line-conductivity kagesi engaba ngu-5.96 × 10 ukuqagela S/m. Lokhu kungenxa yokuthi ukwakheka kwe-elekthronikhi kwama-athomu ethusi kuyivumela ukuthi iqhube kahle yamanje, futhi iyimpahla esetshenziswayo esetshenziswa kakhulu, esetshenziswa kakhulu emikhakheni efana nokudluliswa kwamandla.

Intambo ye-nickel-chromium alloy inokusebenza kahle kukagesi, futhi ukusebenza kwayo kukagesi kuphansi kakhulu kunaleyo yethusi, cishe ngo-1.1×10⁶S/m. Lokhu kungenxa yesakhiwo se-athomu nokusebenzisana kwe-nickel ne-chromium ku-alloy, ukuze ukuqhutshwa kwama-electron kuvinjwe ngezinga elithile.

I-Thermal conductivity

-I-Copper ine-conductivity enhle kakhulu yokushisa, ene-thermal conductivity mayelana ne-401W / (m·K), okwenza ithusi lisetshenziswe kabanzi ezindaweni lapho kudingeka khona ukuhanjiswa okuhle kwe-thermal, njengamadivayisi okukhipha ukushisa.

I-thermal conductivity ye-nickel-chromium alloy ibuthakathaka ngokuqhathaniswa, futhi ukuqhutshwa kwe-thermal ngokuvamile kuphakathi kuka-11.3 no-17.4W/(m·K)

3. Izakhiwo Zamakhemikhali Ezihlukene

Ukumelana Nokugqwala

Ama-alloys e-nickel-chromium anokumelana nokugqwala okuhle, ikakhulukazi ezindaweni ezishisa kakhulu ze-oxidation. I-Nickel ne-chromium zakha ifilimu ye-oxide eminyene ebusweni be-alloy, ivimbela ukusabela okuqhubekayo kwe-oxidation. Isibonelo, emoyeni wokushisa ophakeme, lolu ungqimba lwefilimu ye-oxide lungavikela insimbi ngaphakathi kwe-alloy ekuqhubekeni nokugqwala.

- I-Copper ikhishwa kalula emoyeni ukuze yakhe i-vercas (i-copper carbonate eyisisekelo, ifomula Cu₂(OH)₂CO₃). Ikakhulukazi endaweni enomswakama, ingaphezulu lethusi lizogqwala kancane kancane, kodwa ukumelana kwalo nokugqwala kwamanye ama-asidi angenayo i-oxidizing kuhle kakhulu.

Ukuzinza Kwamakhemikhali

- I-alloy ye-Nichrome inokusimama okuphezulu kwamakhemikhali futhi ingahlala izinzile lapho kukhona amakhemikhali amaningi. Inokubekezelela okuthile kuma-acids, izisekelo namanye amakhemikhali, kodwa futhi ingasabela kuma-acid oxidizing aqinile.

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

4. Ukusetshenziswa Okuhlukile

- i-nickel-chromium alloy wire

- Ngenxa yokumelana kwayo okuphezulu nokumelana nokushisa okuphezulu, isetshenziselwa kakhulu ukwenza izakhi zokushisa zikagesi, njengezintambo zokushisa kumahhavini kagesi nama-heaters amanzi kagesi. Kulawa madivayisi, izintambo ze-nichrome ziyakwazi ukuguqula kahle amandla kagesi ekushiseni.

- Ibuye isetshenziswe kwezinye izikhathi lapho izakhiwo zemishini zidinga ukugcinwa ezindaweni ezishisayo, njengezingxenye zokusekela zamaziko okushisa aphezulu.

- Intambo yethusi

- I-Copper wire isetshenziswa kakhulu ekudluliseni amandla, ngoba ukuhamba kwayo okuhle kagesi kunganciphisa ukulahlekelwa kwamandla kagesi ngesikhathi sokudlulisa. Kuhlelo lwegridi yamandla, inani elikhulu lezintambo zethusi lisetshenziselwa ukwenza izintambo nezintambo.

- Ibuye isetshenziselwe ukwenza ukuxhumana kwezingxenye ze-elekthronikhi. Emikhiqizweni ye-elekthronikhi njengamakhompuyutha nomakhalekhukhwini, izintambo zethusi zingakwazi ukubona ukudluliswa kwesignali kanye nokunikezwa kwamandla phakathi kwezingxenye ezihlukahlukene ze-elekthronikhi.
