China Cr20ni80 NiCr8020 Nicr Alloy Nichrome Waya Wopangira ndi Kutenthetsa Zinthu

Cr20ni80 NiCr8020 Nicr Alloy Nichrome Waya Wotenthetsera Zinthu Chithunzi Chodziwika

Waya wa Cr20ni80 NiCr8020 Nicr Alloy Nichrome wa Element Yotenthetsera

Kufotokozera Kwachidule:

Chipangizo cha NiCr8020 chokhala ndi nambala 2.4869 chimagwiritsidwa ntchito ngati mipiringidzo, mapepala, machubu ndi mawaya a zida zomangira ng'anjo ndi ma conductor otenthetsera. Ndi aloyi ya nickel-chromium heating conductor yogwiritsira ntchito kutentha kwa mpaka 1150 °C ndipo nthawi zambiri imakhala ndi zowonjezera za nthaka yosowa kuti iteteze kwambiri ku okosijeni, makamaka ndi ntchito zosinthira pafupipafupi kapena kusintha kwakukulu kwa kutentha. Kukana dzimbiri la mumlengalenga pa 20 °C kumakhala kwakukulu mpaka kutentha kwapamwamba kwa ntchito, kukana mpweya ndi mpweya wina wokhala ndi mpweya komanso mpweya wochepa wa okosijeni wokhala ndi nayitrogeni nakonso kumakhala kwakukulu, komabe kumakhala kochepa ku okosijeni komanso kuchepetsa mpweya wokhala ndi sulfure. Kukana ku okosijeni kumakhala kwakukulu. Kugwiritsa ntchito ma uvuni amagetsi amafakitale, ma uvuni a enamelling, zida zapakhomo, zotenthetsera zosungira usiku.
