1.Different Ingredients
Nickel chromium alloywaya inonyanya kuumbwa nickel (Ni) uye chromium (Cr), uye inogonawo kunge iine zvidiki zvezvimwe zvinhu. Zviri mukati nickel mu nickel-chromium alloy kazhinji inenge 60% -85%, uye zviri mukati chromium inenge 10% -25%. Semuenzaniso, iyo yakajairika nickel-chromium alloy Cr20Ni80 ine chromium yemukati inosvika makumi maviri muzana uye nickel yemukati inosvika makumi masere muzana.
Chinhu chikuru chemhangura yemhangura ndeyemhangura (Cu), iyo kuchena kwayo kunogona kusvika kupfuura 99.9%, yakadai seT1 yakachena mhangura, mhangura yemhangura inosvika 99.95%.
2.Different Physical Properties
Color
- Nichrome waya kazhinji sirivha grey. Izvi zvinodaro nekuti simbi inopenya yenickel nechromium inosanganiswa kupa ruvara urwu.
- Iyo copper wire ruvara ndeye purplish tsvuku, inova ndiyo yakajairika ruvara rwemhangura uye ine simbi inopenya.
Density
- The linear density ye nickel-chromium alloy yakakura, kazhinji inosvika 8.4g/cm³. Semuenzaniso, 1 cubic mita ye nichrome waya ine huremu hunosvika 8400 kg.
- Thewaya yemhanguradensity ingangoita 8.96g/cm³, uye vhoriyamu imwechete yewaya yemhangura inorema zvishoma pane nickel-chromium alloy waya.
Melting Point
-Nickel-chromium alloy ine yakakwira kunyungudika, yakatenderedza 1400 ° C, iyo inoita kuti ikwanise kushanda pakudziya kwepamusoro pasina kunyungudika nyore.
-Kunyungudika kwemhangura inenge 1083.4 ℃, iyo yakaderera pane iyo nickel-chromium alloy.
Electrical Conductivity
-Copper wire inobata magetsi zvakanaka kwazvo, mumamiriro ezvinhu, mhangura ine magetsi ekugadzirisa anenge 5.96 × 10 kufungidzira S / m. Izvi zvinodaro nekuti chimiro chemagetsi chemaatomu emhangura chinoibvumira kuita ikozvino zvakanaka, uye inowanzoshandiswa conductive zvinhu, iyo inoshandiswa zvakanyanya muminda yakadai sekufambisa kwemagetsi.
Nickel-chromium alloy waya ine magetsi asina kunaka, uye magetsi ayo akadzikira zvakanyanya pane aya emhangura, angangoita 1.1×10⁶S/m. Izvi zvinokonzerwa nechimiro cheatomu uye kupindirana kwe nickel uye chromium mu alloy, kuitira kuti kufambiswa kwemaerekitironi kunotadziswa kusvika pamwero wakati.
Thermal conductivity
-Mhangura ine yakanakisa thermal conductivity, ine thermal conductivity inosvika 401W / (m·K), iyo inoita mhangura inoshandiswa zvakanyanya munzvimbo dzinodiwa kunaka kwekupisa kwekushisa, senge midziyo yekupisa kupisa.
Thermal conductivity yenickel-chromium alloy haina kusimba, uye thermal conductivity kazhinji iri pakati pe11.3 ne17.4W/(m·K)
3. Yakasiyana Chemical Properties
Corrosion Resistance
Nickel-chromium alloys ane yakanaka corrosion resistance, kunyanya munzvimbo dzakanyanya tembiricha oxidation. Nickel uye chromium zvinogadzira dense oxide firimu pamusoro peiyo alloy, kudzivirira kumwe kuita oxidation. Semuenzaniso, mumhepo yekupisa yepamusoro, iyi firimu yeoxyde inogona kuchengetedza simbi mukati mealloy kubva pakuenderera mberi nekuora.
- Mhangura inoiswa oxidized zviri nyore mumhepo kuita vercas (basic copper carbonate, formula Cu₂(OH)₂CO₃). Kunyanya munzvimbo ine hunyoro, pamusoro pemhangura ichasvibiswa zvishoma nezvishoma, asi kurwisana kwayo kwehutu mune mamwe asiri-oxidizing acids akanaka.
Kugadzikana Kwemakemikari
- Nichrome alloy ine yakakwirira kugadzikana kwemakemikari uye inogona kuramba yakagadzikana muhupo hwemakemikari akawanda. Iyo ine kumwe kushivirira kune acids, mabhesi uye mamwe makemikari, asi inogona zvakare kuita mune yakasimba oxidizing acids.
- Mhangura mune mamwe maoxidants akasimba (akadai se nitric acid) pasi pekuita kweakanyanya chisimba chemakemikari reaction, iyo reaction equation ndeye \(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).
4. Mashandisirwo Akasiyana
- nickel-chromium alloy waya
- Nekuda kwekukwirira kwayo kwepamusoro uye kushomeka kwekushisa kwakanyanya, inonyanya kushandiswa kugadzira magetsi ekudziya zvinhu, sekudziya waya mumavheni emagetsi uye magetsi emvura anopisa. Mune zvishandiso izvi, nichrome waya dzinokwanisa kushandura zvakanaka simba remagetsi mukupisa.
-Iyo inoshandiswawo mune dzimwe nguva uko michina zvivakwa zvinoda kuchengetedzwa munzvimbo dzekushisa dzakanyanya, senge zvikamu zvekutsigira zvemoto wekushisa.
- Mhangura waya
- Copper wire inonyanya kushandiswa pakufambisa simba, nokuti maitiro ayo akanaka emagetsi anogona kuderedza kurasikirwa kwesimba remagetsi panguva yekufambisa. Mumagetsi emagetsi emagetsi, nhamba huru yemhangura yemhangura inoshandiswa kugadzira waya netambo.
-Inoshandiswawo kugadzira zvinongedzo zvemagetsi zvikamu. Muzvigadzirwa zvemagetsi zvakaita semakomputa nenharembozha, waya dzemhangura dzinogona kuona kutapurirana kwechiratidzo uye kupihwa kwemagetsi pakati pezvinhu zvakasiyana zvemagetsi.
