NI90Cr10, yomwe imadziwikanso kuti Nichrome 90 kapena NiCr 90/10, ndi alloy yogwira ntchito kwambiri yomwe imapereka kukana kwambiri kutentha komanso dzimbiri. Ili ndi malo osungunuka kwambiri a 1400 ° C (2550 ° F) ndipo imatha kusunga mphamvu zake ndi kukhazikika ngakhale pa kutentha pamwamba pa 1000 ° C (1832 ° F).

Alloy iyi imagwiritsidwa ntchito kwambiri pazinthu zomwe zimafuna zinthu zotenthetsera, monga ng'anjo zamakampani, ma uvuni, ndi zida zotenthetsera. Amagwiritsidwanso ntchito popanga ma thermocouples, omwe amagwiritsidwa ntchito kuyeza kutentha m'njira zosiyanasiyana zamakampani.

NI90Cr10 ili ndi kukana kwabwino kwa okosijeni, zomwe zimapangitsa kuti ikhale yothandiza kwambiri m'malo otentha kwambiri pomwe zida zina zimatha kuwononga ndikuwonongeka mwachangu. Imakhalanso ndi zida zabwino zamakina, monga kulimba kwamphamvu kwambiri komanso ductility yabwino, zomwe zimapangitsa kuti zikhale zosavuta kupanga ndi mawonekedwe.

Zikafika pamapaipi opangidwa ndi aloyiyi, nthawi zambiri amagwiritsidwa ntchito m'malo omwe kutentha kwambiri komanso kuwononga kumakhalapo, monga mafakitale opanga mankhwala, petrochemical, ndi mafakitale opanga magetsi. Makhalidwe enieni a chitoliro, monga kukula kwake, makulidwe a khoma, ndi kuthamanga kwake, zingadalire pa ntchito yomwe ikufunidwa komanso zofunikira za polojekitiyo.

Mapaipi a NI90Cr10 nthawi zambiri amagwiritsidwa ntchito m'malo omwe kutentha kwambiri komanso kuwononga kumakhalapo, monga popanga mankhwala, petrochemical, ndi mafakitale opanga magetsi. Mapaipiwa amadziwika chifukwa chokana kwambiri makutidwe ndi okosijeni ndi dzimbiri, zomwe zimawapangitsa kukhala abwino kugwiritsidwa ntchito m'malo omwe amakhala ndi acidic kapena alkaline solution. Zina mwazomwe zimagwiritsidwa ntchito pamapaipi a NI90Cr10 ndi awa:

Kukonzekera kwa Chemical: Mapaipi a NI90Cr10 nthawi zambiri amagwiritsidwa ntchito popanga mankhwala komwe kumakhala kutentha kwambiri komanso zowononga. Mapaipiwa atha kugwiritsidwa ntchito kunyamula mankhwala owononga ndipo amatha kupirira akakumana ndi acidic kapena alkaline solution.
Petrochemical: mapaipi a NI90Cr10 amagwiritsidwanso ntchito m'makampani a petrochemical, komwe amagwiritsidwa ntchito popanga mafuta ndi gasi. Amatha kupirira kutentha kwambiri ndi kupanikizika ndipo sagonjetsedwa ndi dzimbiri, kuwapanga kukhala abwino kugwiritsidwa ntchito m'madera ovuta.
Kupanga magetsi: mapaipi a NI90Cr10 amagwiritsidwa ntchito popanga magetsi monga ma turbines a gasi ndi ma turbines a nthunzi. Mapaipiwa amatha kupirira kutentha kwambiri komanso kupanikizika kwambiri ndipo amalimbana ndi dzimbiri, kuwapanga kukhala abwino kuti agwiritsidwe ntchito m'mafakitale amagetsi.
Zamlengalenga: Mapaipi a NI90Cr10 amagwiritsidwanso ntchito pazamlengalenga komwe kumakhala kutentha kwambiri komanso zowononga. Mapaipiwa atha kugwiritsidwa ntchito m'mainjini a jet, mainjini a rocket, ndi zida zina zamlengalenga zogwira ntchito kwambiri.

Makhalidwe enieni a mapaipi a NI90Cr10, monga kukula kwake, makulidwe a khoma, ndi kukakamizidwa, zimatengera zomwe akufuna komanso zofunikira za polojekitiyi. Mipopeyo ikhoza kusinthidwa kuti ikwaniritse zosowa zenizeni za ntchito, monga kutentha kofunikira ndi kupanikizika, mtundu wamadzimadzi kapena mpweya, ndi chilengedwe. Ponseponse, kuphatikiza kwapadera kwa kukana kutentha kwapamwamba, mphamvu zamakina, komanso kukana kwa dzimbiri kumapangitsa mapaipi a NI90Cr10 kukhala chinthu chamtengo wapatali pamitundu yosiyanasiyana yogwira ntchito kwambiri m'mafakitale osiyanasiyana.
