1.Zvinhu Zvakasiyana

Nickel chromium alloyWaya yacho inonyanya kuumbwa ne nickel (Ni) ne chromium (Cr), uye inogonawo kunge iine zvimwe zvinhu zvishoma. Zviri mukati me nickel mu nickel-chromium alloy zvinowanzova 60%-85%, uye zviri mukati me chromium zvinenge 10%-25%. Semuenzaniso, nickel-chromium alloy Cr20Ni80 yakajairika ine chromium inosvika 20% uye nickel inosvika 80%.

Chinhu chikuru chewaya yemhangura imhangura (Cu), iyo kuchena kwayo kunogona kusvika kupfuura 99.9%, senge mhangura yakachena yeT1, huwandu hwemhangura hwakakwira kusvika 99.95%.

2. Hunhu Hwakasiyana Hwemuviri

Ruvara

- Waya yeNichrome inowanzova yegrey yesirivha. Izvi zvinokonzerwa nekuti kupenya kwesimbi kwenickel nechromium zvinosanganiswa kuti zvipe ruvara urwu.

- Ruvara rwewaya yemhangura rutsvuku rwepepuru, rwunova ruvara rwakajairika rwemhangura uye rune kupenya kwesimbi.

Kuwanda kwevanhu

- Kuwanda kwe nickel-chromium alloy kwakakura zvakanyanya, kazhinji kunosvika 8.4g/cm³. Semuenzaniso, 1 cubic meter ye nichrome wire ine huremu hunosvika 8400 kg.

- Iyowaya yemhangurakuwanda kwayo kuri pa8.96g/cm³, uye huwandu hwakaenzana hwewaya yemhangura hunorema zvishoma kupfuura waya yenickel-chromium alloy.

Nzvimbo Yokunyunguduka

-Nickel-chromium alloy ine nzvimbo yekunyunguduka yakanyanya, inenge 1400°C, izvo zvinoita kuti ikwanise kushanda pakupisa kwakanyanya isina kunyunguduka nyore.

-Pokunyunguduka kwemhangura inenge 1083.4℃, iyo yakaderera pane iyo ye nickel-chromium alloy.

Kufambisa Kwemagetsi

-Waya yemhangura inofambisa magetsi zvakanaka, kana iri mumamiriro akajairwa, mhangura ine simba remagetsi rinosvika 5.96×10 fungidzira S/m. Izvi zvinodaro nekuti chimiro chemagetsi chemaatomu emhangura chinoibvumira kufambisa magetsi zvakanaka, uye chinhu chinoshandiswa zvakanyanya muzvinhu zvakaita sekutumira magetsi.

Waya ye alloy ye nickel-chromium haina simba remagetsi, uye simba rayo remagetsi rakaderera zvikuru pane remhangura, rinenge 1.1×10⁶S/m. Izvi zvinokonzerwa nechimiro chemaatomu uye kudyidzana kwe nickel ne chromium mu alloy, zvekuti kufambiswa kwemaerekitironi kunokanganiswa kusvika pamwero wakati.

Kufambisa kwekupisa

-Mhangura ine simba rekupisa rakanaka kwazvo, ine simba rekupisa rinosvika 401W/(m·K), izvo zvinoita kuti mhangura ishandiswe zvakanyanya munzvimbo dzinodiwa simba rekupisa rakanaka, senge zvishandiso zvinobvisa kupisa.

Kufambiswa kwemafuta emuchina we nickel-chromium alloy hakuna kusimba, uye kufambiswa kwemafuta emuchina we thermal kunowanzova pakati pe11.3 ne17.4W/(m·K)

3. Hunhu Hwakasiyana hweMakemikoro

Kuramba Kuora

Ma alloy e nickel-chromium ane simba rekudzivirira ngura, kunyanya munzvimbo dzine tembiricha yakakwira. Nickel ne chromium zvinoumba firimu re dense oxide pamusoro pe alloy, zvichidzivirira mamwe maitiro e oxidation. Semuenzaniso, mumhepo ine tembiricha yakakwira, jira iri re oxide film rinogona kudzivirira simbi iri mukati me alloy kubva mukuora kwakawanda.

- Mhangura inonyungudika nyore nyore mumhepo kuti igadzire vercas (basic copper carbonate, formula Cu₂(OH)₂CO₃). Kunyanya munzvimbo ine hunyoro, pamusoro pemhangura pachapera ngura zvishoma nezvishoma, asi kuramba kwayo ngura mune mamwe maasidhi asina ngura kwakanaka.

Kugadzikana kweMakemikari

- Nichrome alloy ine kugadzikana kwakanyanya kwemakemikari uye inogona kuramba yakasimba kana paine makemikari akawanda. Ine kushivirira kwakati kune acids, bases uye mamwe makemikari, asi inogonawo kuita zvine simba mu oxidizing acids.

- Mhangura mune mamwe ma oxidants akasimba (akadai se nitric acid) pasi pekuita kwemakemikari ane simba, reaction equation ndeye \(3Cu + 8HNO₃(dilute)=3Cu(NO₃ +2NO↑ + 4H₂O\).

4. Mashandisirwo Akasiyana

- waya yesimbi ye nickel-chromium

- Nekuda kwekudzivirira kwayo zvakanyanya uye kuramba kupisa kwakanyanya, inonyanya kushandiswa kugadzira zvinhu zvinodziya zvemagetsi, zvakaita sewaya dzinodziya mumaovheni emagetsi uye zvinodziya mvura zvemagetsi. Muzvishandiso izvi, waya dze nichrome dzinokwanisa kushandura simba remagetsi kuita kupisa zvinobudirira.

- Inoshandiswawo mune dzimwe nguva apo hunhu hwemakanika hunofanirwa kuchengetedzwa munzvimbo dzinopisa zvakanyanya, senge zvikamu zvinotsigira maovheni anopisa zvakanyanya.

- Waya yemhangura

- Waya yemhangura inonyanya kushandiswa pakufambiswa kwemagetsi, nekuti kufambiswa kwayo zvakanaka kwemagetsi kunogona kuderedza kurasikirwa kwesimba remagetsi panguva yekufambiswa kwemagetsi. Muhurongwa hwemagetsi, waya dzakawanda dzemhangura dzinoshandiswa kugadzira waya netambo.

- Inoshandiswawo kugadzira kubatanidza zvinhu zvemagetsi. Muzvigadzirwa zvemagetsi zvakaita semakombiyuta nemafoni, waya dzemhangura dzinogona kutumira masaini uye kupa magetsi pakati pezvinhu zvakasiyana-siyana zvemagetsi.
