Mu dziko la sayansi ya zinthu ndi uinjiniya wamagetsi, funso lakuti ngati nichrome ndi chowongolera magetsi chabwino kapena choipa lakhala likukhudza ofufuza, mainjiniya, ndi akatswiri amakampani omwe. Monga kampani yotsogola pankhani ya ma alloys otenthetsera magetsi, Tankii ali pano kuti afotokoze nkhani yovutayi.

Nichrome, alloy yomwe imapangidwa makamaka ndi nickel ndi chromium, ili ndi mphamvu zapadera zamagetsi. Poyamba, poyerekeza ndi zitsulo zoyendetsa kwambiri monga mkuwa kapena siliva, nichrome ingawoneke ngati conductor yofooka. Mwachitsanzo, mkuwa uli ndi conductivity yamagetsi ya pafupifupi 59.6×10^6 S/m pa 20 °C, pomwe conductivity ya siliva ili pafupifupi 63×10^6 S/m. Mosiyana ndi zimenezi, nichrome ili ndi conductivity yotsika kwambiri, nthawi zambiri imakhala pakati pa 1.0×10^6 - 1.1×10^6 S/m. Kusiyana kwakukulu kumeneku kwa conductivity kungapangitse munthu kutcha nichrome ngati conductor "yoyipa".

Komabe, nkhaniyi siimathera pamenepo. Kutsika kwa mphamvu zamagetsi kwa nichrome kwenikweni ndi chinthu chofunikira kwambiri m'magwiritsidwe ntchito ambiri. Chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi nichrome ndi mu zinthu zotenthetsera. Pamene mphamvu yamagetsi imadutsa mu kondakitala, malinga ndi lamulo la Joule (P = I²R, pomwe P ndi mphamvu yotayika, I ndi mphamvu yamagetsi, ndipo R ndi kukana), mphamvu imatayika mu mawonekedwe a kutentha. Kukana kwakukulu kwa Nichrome poyerekeza ndi ma kondakitala abwino monga mkuwa kumatanthauza kuti pa mphamvu inayake, kutentha kwambiri kumapangidwa muwaya wa nichromeIzi zimapangitsa kuti ikhale chinthu choyenera kugwiritsidwa ntchito monga ma toaster, ma heater amagetsi, ndi ma ng'anjo zamafakitale.

Kuphatikiza apo, nichrome ilinso ndi kukana kwambiri okosijeni ndi dzimbiri. M'malo otentha kwambiri komwe zinthu zotenthetsera nthawi zambiri zimagwiritsidwa ntchito, kuthekera kokana kuwonongeka ndikofunikira. Ngakhale kuti kutsika kwa mphamvu yake kungakhale vuto pakugwiritsa ntchito komwe kuchepetsa kukana ndikofunikira, monga m'mizere yotumizira magetsi, imakhala mwayi wapadera pakugwiritsa ntchito kutentha.

Kuchokera pamalingaliro a [Name Company], kumvetsetsa makhalidwe a nichrome ndikofunikira kwambiri pakupanga zinthu zathu ndi kupanga zatsopano. Timapanga zinthu zosiyanasiyana zotenthetsera zochokera ku nichrome zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Gulu lathu la R & D likugwira ntchito nthawi zonse pokonza kapangidwe ka nichrome alloys kuti liwongolere magwiridwe antchito awo. Mwachitsanzo, mwa kusintha chiŵerengero cha nickel ndi chromium, titha kusintha kukana kwamagetsi ndi mawonekedwe a makina a alloy kuti agwirizane bwino ndi zofunikira zinazake zogwiritsidwa ntchito.

Pomaliza, kusankhidwa kwa nichrome ngati chowongolera magetsi chabwino kapena choipa kumadalira kwathunthu momwe imagwiritsidwira ntchito. Pankhani ya kupititsa patsogolo magetsi pamagetsi - kutumiza bwino, sikugwira ntchito bwino ngati zitsulo zina. Koma pankhani yotenthetsera magetsi, makhalidwe ake amawapangitsa kukhala chinthu chosasinthika. Pamene ukadaulo ukupitirirabe kusintha, tikusangalala kufufuza njira zatsopano zogwiritsira ntchito nichrome ndi zinthu zina zotenthetsera kuti tikwaniritse zosowa zomwe zikukulirakulira m'mafakitale osiyanasiyana. Kaya ndikupanga njira zotenthetsera zamagetsi zambiri - zogwira ntchito bwino m'mabanja kapena zinthu zotenthetsera zamagetsi zogwira ntchito kwambiri, makhalidwe apadera anichromeipitilizabe kuchita gawo lofunika kwambiri pakupanga tsogolo la ntchito zotenthetsera zamagetsi.
