Matamba a malonda

Nichrome, omwe amadziwikanso kuti nickel chrome, ndi chithokomiro chopangidwa ndi kusakaniza nickel, chromium ndipo, nthawi zina, chitsulo. Kudziwika bwino chifukwa cha kutentha kwake, komanso kukana kwake kuvunda ndi oxidation, the levesi imathandiza kwambiri pazinthu zingapo. Kuchokera pakupanga mafakitale kuntchito, Nichrome mu mawonekedwe a waya amapezeka pamitundu yosiyanasiyana ya malonda, zaluso ndi zida. Imapezanso ntchito m'makonzedwe apadera.

Waya wa Nichrome ndi alloy opangidwa kuchokera ku nickel ndi chromium. Imatsutsa kutentha ndi oxidation ndipo imakhala chinthu chochenjera pazogulitsa monga zokutira ndi zodetsa tsitsi. Obbysists amagwiritsa ntchito waya wa nichrome m'chifakiro ndi matalala. Waya amathanso kupezekanso ku labotaries, zomanga ndi zamagetsi.

Chifukwa waya wa Nichrome ndi wogwirizana kwambiri ndi magetsi, ndizothandiza kwambiri monga chinthu chotenthetsera mu malonda ndi zida zapakhomo. Zosangalatsa ndi zodetsa tsitsi zimagwiritsa ntchito ma coils a nichrome a waya kuti mupange kutentha kwakukulu, monganso zolimbitsa matoma ndi osungiramo ziweto. Ngwi ya mafakitale imagwiritsanso ntchito waya wa nichrome kuti igwire ntchito. Kutalika kwa waya ku Nichrome kumatha kugwiritsidwanso ntchito kupanga waya wotentha, womwe ungagwiritsidwe ntchito kunyumba kapena m'malo opanga mafakitale kuti adulidwe ndikupanga zikopa zina.

Waya wa Nichrome amapangidwa ndi alloy alloy omwe amapangidwa makamaka ndi nickel, cromium, ndi chitsulo. Nichrome imadziwika ndi kusagwirizana kwake kwakukulu ndi kukana kwabwino kwa oxida. Wai waya wa Nichrome alinso ndi duckitity yabwino mukatha kugwiritsa ntchito komanso kukhala bwino kwambiri.

Chiwerengero chomwe chimabwera pambuyo pa waya wa nichrome umawonetsa kuchuluka kwa nickel mu anoya. Mwachitsanzo, "Nichrome 60" ali pafupifupi 60% nickel mu kapangidwe kake.

Mapulogalamu a waya wa Nichrome amaphatikiza zinthu zotenthetsera zodetsa tsitsi, kutentha pamoto, ndi chithandizo cha croramic.
