Yintoni umahluko phakathi kwe-nichrome kunye nocingo lobhedu?

1.Iizithako ezahlukeneyo

I-Nickel chromium alloyucingo luqulunqwe ikakhulu nge-nickel (Ni) kunye ne-chromium (Cr), kwaye inokuqulatha izixa ezincinci zezinye izinto. Umxholo we-nickel kwi-nickel-chromium alloy ngokubanzi malunga ne-60% -85%, kunye nomxholo we-chromium malunga ne-10% -25%. Ngokomzekelo, i-nickel-chromium alloy eqhelekileyo i-Cr20Ni80 inomxholo we-chromium malunga ne-20% kunye nomxholo we-nickel malunga ne-80%.

Inxalenye ephambili yocingo lobhedu lubhedu (Cu), ubunyulu bayo bunokufikelela ngaphezu kwe-99.9%, njenge-T1 yethusi ecocekileyo, umxholo wobhedu ophakamileyo kwi-99.95%.

2.IiPropati zoMzimba ezahlukeneyo

Umbala

- I-Nichrome wire idla ngokuba yisilivere engwevu. Oku kungenxa yokuba i-metallic luster yenikeli kunye nechromium ixutywe ukunika lo mbala.

- Umbala wocingo lwekopolo upurplish obomvu, wona ngumbala wobhedu oqhelekileyo kwaye unokukhanya kwesinyithi.

Ukuxinana

- Uxinaniso lomgca we-nickel-chromium alloy lukhulu kakhulu, jikelele malunga ne-8.4g/cm³. Ngokomzekelo, i-1 cubic meter yocingo lwe-nichrome inobunzima malunga ne-8400 kg.

- Iucingo lobheduUxinzelelo malunga ne-8.96g/cm³, kwaye umthamo ofanayo wocingo lobhedu unzima kancinci kunocingo lwe-nickel-chromium alloy.

Indawo yokunyibilika

-I-Nickel-chromium alloy ine-high melting point, malunga ne-1400 ° C, eyenza ikwazi ukusebenza kumaqondo aphezulu ngaphandle kokunyibilika lula.

-Indawo yokunyibilika kobhedu malunga ne-1083.4 ℃, engaphantsi kune-nickel-chromium alloy.

Ukuqhuba koMbane

-I-Copper wire iqhuba umbane kakuhle kakhulu, kwimeko esemgangathweni, ubhedu lunombane we-conductivity malunga ne-5.96 × 10 guess S / m. Oku kungenxa yokuba i-electronic structure yee-athomu zobhedu ivumela ukuba iqhube kakuhle ngoku, kwaye yinto eqhelekileyo esetyenziswayo eqhubayo, esetyenziswa ngokubanzi kwimimandla efana nokuhanjiswa kwamandla.

I-Nickel-chromium alloy wire ine-conductivity engalunganga yombane, kwaye i-conductivity yayo yombane ingaphantsi kakhulu kunokobhedu, malunga ne-1.1×10⁶S/m. Oku kungenxa yesakhiwo se-athomu kunye nokusebenzisana kwe-nickel kunye ne-chromium kwi-alloy, ukwenzela ukuba ukuqhuba kwee-electron kuthintelwe kwinqanaba elithile.

I-Thermal conductivity

-I-Copper ine-conductivity egqwesileyo ye-thermal, kunye ne-thermal conductivity malunga ne-401W / (m·K), eyenza ubhedu lusetyenziswe ngokubanzi kwiindawo apho kufuneka khona ukuhanjiswa kakuhle kwe-thermal, njengezixhobo zokushisa ukushisa.

I-thermal conductivity ye-nickel-chromium alloy ithambile kwaye i-thermal conductivity iphakathi kwe-11.3 kunye ne-17.4W/(m·K)

3. Iipropati ezahlukeneyo zeMichiza

Ukunyangwa kokuMhlwa

Ingxubevange ye-nickel-chromium inokumelana ne-corrosion elungileyo, ngakumbi kwiindawo ezinobushushu obuphezulu be-oxidation. I-Nickel kunye ne-chromium zenza ifilimu eshinyeneyo ye-oxide kumphezulu we-alloy, ukuthintela ukusabela okungaphezulu kwe-oxidation. Ngokomzekelo, kwiqondo lokushisa eliphezulu lomoya, olu luhlu lwefilimu ye-oxide lunokukhusela isinyithi ngaphakathi kwe-alloy ekuqhubeni ukubola.

- I-Copper i-oxidized ngokulula emoyeni ukwenza i-vercas (isiseko se-copper carbonate, ifomula Cu₂ (OH) ₂CO₃). Ngokukodwa kwindawo efumileyo, umphezulu wobhedu uya kuthotywa ngokuthe ngcembe, kodwa ukuxhathisa kwayo kwi-corrosion kwezinye ii-asidi ezingenayo i-oxidizing kulungile.

Uzinzo lweMichiza

- I-alloy ye-Nichrome inozinzo oluphezulu lweekhemikhali kwaye inokuhlala izinzile phambi kweekhemikhali ezininzi. Inokunyamezela okuthile kwi-acids, iziseko kunye nezinye iikhemikhali, kodwa inokusabela kwi-acids oxidizing eqinile.

- I-Copper kwezinye ii-oxidants ezinamandla (ezifana ne-nitric acid) phantsi kwesenzo sokusabela kweekhemikhali ezinobundlobongela, i-reaction equation yi \(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Ukusetyenziswa Okuhlukeneyo

- i-nickel-chromium alloy wire

- Ngenxa yokumelana kwayo okuphezulu kunye nokumelana nokushisa okuphezulu, isetyenziselwa kakhulu ukwenza izinto zokufudumeza zombane, ezifana neengcingo zokufudumeza kwii-ovens zombane kunye nezifudumezi zamanzi zombane. Kwezi zixhobo, iingcingo ze-nichrome ziyakwazi ukuguqula ngokufanelekileyo amandla ombane kubushushu.

- Ikwasetyenziselwa kwezinye iimeko apho iipropati zomatshini zifuna ukugcinwa kwiindawo eziphezulu zokushisa, njengeendawo ezixhasayo zokushisa okuphezulu.

- Ucingo lobhedu

- I-Copper wire isetyenziselwa ukuhanjiswa kwamandla, kuba ukuqhutyelwa kwayo kakuhle kombane kunokunciphisa ukulahlekelwa kwamandla ombane ngexesha lokuhambisa. Kwinkqubo yegridi yamandla, inani elikhulu leentambo zobhedu zisetyenziselwa ukwenza iingcingo kunye neentambo.

- Ikwasetyenziselwa ukwenza uqhagamshelo lwezixhobo ze-elektroniki. Kwiimveliso zombane ezifana neekhompyuter kunye neefowuni eziphathwayo, iingcingo zobhedu zinokuqonda ukuhanjiswa komqondiso kunye nonikezelo lwamandla phakathi kwezinto ezahlukeneyo zombane.
