Lub ntsiab tivthaiv hluav taws xob yog tooj liab (CU), uas nws tuaj yeem ncav cuag ntau dua 99.9%, xws li T1 Ntsiav cov ntsiab lus zoo li 99.95%.

2.different lub cev muaj zog

Xim

- Nichrome hlau feem ntau yog nyiaj grey. Qhov no yog vim tias cov xim hlau luster ntawm npib tsib xee thiab chromium yog tov los muab cov xim no.

- Cov xaim tooj liab xim yog cov xim liab, uas yog cov xim raug tooj liab ntawm tooj liab thiab muaj cov xim hlau lus.

Ceev

- Cov kab tawm ntawm Nickel-chromium alloy yog tus loj, feem ntau nyob ib ncig ntawm 8.4g / cm³. Piv txwv li, 1 cubic meter ntawm nichrome hlau muaj qhov loj ntawm txog 8400 kg.

- tusTooj liab hlauQhov ceev yog li 8.96g / cm³, thiab tib lub ntim ntawm tooj liab hlau yog me ntsis hnyav dua li npib tsib xee-chromium alloy hlau.

Melting point

-Nickel-chromium alloy muaj lub siab melting point, nyob ib ncig ntawm 1400 ° C, uas ua rau nws muaj peev xwm ua haujlwm ntawm qhov yooj yim tsis muaj melting yooj yim.

-Qhov melting taw tes ntawm tooj liab yog kwv yees li 1083.4 ℃, uas yog qis dua li ntawm Nickel-liclo alloy.

Hluav Taws Xob Kev Tshaj Tawm

-Cov xov hluav taws xob coj hluav taws xob zoo heev, hauv cov qauv txheem, tooj liab muaj hluav taws xob cuam tshuam nrog 5.96 × 10 kwv yees s / m. Qhov no yog vim tias cov qauv hluav taws xob atomer atomer atoms rau nws kom ua tau zoo tam sim no, thiab nws yog qhov siv tau siv dav hauv kev sib kis.

Nickel-chromium alloy hlau muaj hluav taws xob tsis zoo, thiab hluav taws xob conduction yog qhov qis dua li ntawm tooj liab, txog 1.1 × 10⁶s / m. Qhov no yog vim yog cov qauv atomic thiab kev sib cuam tshuam ntawm npib tsib xee thiab chromium nyob rau hauv alloy, yog li ntawd qhov kev conduction ntawm cov tshuab hluav taws xob tau cuam tshuam rau qee yam.

Thermal conductivity

-Cov khoom siv cov thermal zoo heev, nrog lub thermal conductivity ntawm kwv yees siv nyob rau hauv cov chaw uas zoo thermal conductivity yog yuav tsum tau, xws li tshav kub dissipation pab kiag li lawm.

Lub thermal conductivity ntawm npib tsib xee-chromium alloy tsis muaj zog, thiab cov thermal conductivity feem ntau ntawm 11.3 thiab 17.4w / (my. (my. (my.

3. Cov tshuaj sib txawv

Corrosion Kuj

Nickel-chromium alloys muaj zoo corrosion tsis kam, tshwj xeeb tshaj yog nyob rau hauv cov ntsuas kub thiab txias oxidation ib puag ncig. Npib tsib xee thiab chromium form ib tug dense oxide zaj duab xis nyob rau saum npoo ntawm alloy, tiv thaiv kev tawm tsam oxidation ntxiv. Piv txwv li, hauv qhov kub cua sov, txheej no ntawm oxide zaj duab xis tuaj yeem tiv thaiv cov hlau hauv cov alloy los ntawm kev corrosion ntxiv.

- Tooj liab yooj yim oxidized rau hauv huab cua los ua ib tug vercas (Baster tooj liab Carbonate, Formula Cu₂ (Oh) ₂ces₃). Tshwj xeeb tshaj yog nyob rau hauv ib puag ncig huab cua, nyob rau ntawm tooj liab yuav maj mam ua corroded, tab sis nws corrosion tsis kam nyob rau hauv qee cov acids tsis-oxidizing acids yog qhov zoo.

Tshuaj Muaj Peev Xwm

- Nichrome alloy muaj cov tshuaj siab ruaj khov thiab tuaj yeem ruaj khov nyob rau hauv muaj ntau yam tshuaj lom neeg. Nws muaj qee qhov tsis kam rau cov kua qaub, hauv paus thiab lwm yam tshuaj, tab sis nws tseem tuaj yeem hnov ​​mob oxidizing cov kua qaub.

- Tooj liab hauv qee cov oxidants (xws li nitric acid) nyob rau hauv qhov kev txiav txim ntawm kev sib deev ntau dua yog \ (Dilute) = 3CU (No₃ + 4h₂o \).

4. Sib txawv siv

- Nickel-chromium alloy hlau

- Vim nws cov siab tiv taus kub, nws yog tsuas yog siv los ua cov hluav taws xob cua sov, xws li cov cua kub roj hauv hluav taws xob ncu thiab cua sov dej cua sov. Nyob rau hauv cov cuab yeej siv no, nichrome cov xov hlau muaj peev xwm hloov tau zoo hloov hluav taws xob lub zog rau hauv tshav kub.

- Nws tseem siv nyob rau qee lub sijhawm uas cov khoom siv neeg kho tshuab yuav tsum tau tswj xyuas hauv ib puag ncig kub thiab cua sov siab li cas ntawm cov cua sov kub.

- Tooj liab hlau

- Tooj liab hlau feem ntau yog siv rau kev sib kis lub hwj chim, vim tias nws cov hluav taws xob zoo tuaj yeem txo cov kev poob ntawm hluav taws xob thaum muaj kev kis. Nyob rau hauv lub hwj chim grid system, ntau tus xov tooj tooj liab tooj liab tau siv los ua cov xov hlau thiab cable.

- Nws tseem siv los ua kev sib txuas rau cov hluav taws xob hluav taws xob. Hauv cov khoom siv hluav taws xob xws li khoos phis tawj thiab xov tooj ntawm tes, tooj liab tuaj yeem paub cov teeb liab kis thiab muab hluav taws xob sib xyaw ntawm ntau yam hluav taws xob.
