Litšebeliso tsa Bohlokoa tsa Terata ea Nichrome

1. Lisebelisoa tsa Lapeng

Terata ea Nichrome ke motheo oa lisebelisoa tsa ho futhumatsa tsa letsatsi le letsatsi. Li-toaster, li-dryer tsa moriri, li-onto le li-kettle tsa motlakase li itšetlehile ka bokhoni ba tsona ba ho hlahisa mocheso o potlakileng le o ts'oanang. Mohlala,nichrome 60e sebelisoa haholo lisebelisoa tse futhumatsang mocheso o itekanetseng joalo ka li-grill le li-heater tsa polokelo, ha nichrome 80 (Ni80Cr20) e ipabola lits'ebetsong tse matla joalo ka li-heater tsa metsi le li-irone tsa ho soldering ka lebaka la ho khomarela ha eona ka oxide e phahameng le ho phela nako e telele915.

2. Mekhoa ea Liindasteri le ea Tlhahiso

Libakeng tsa indasteri, terata ea nichrome e matlafatsa lifono tsa motlakase, li-kiln, le lisebelisoa tsa ho sebetsana le mocheso. Ho hanela ha eona ho thekesela—ho boloka botsitso ba sebopeho tlas'a khatello ea nako e telele mochesong o kaholimo ho 400°C—ho e etsa hore e be ntle bakeng sa ho annealing, ho qhibiliha le kalafo ea mocheso315. Liindasteri tse kang metallurgy le ceramics li sebelisa li-strips tsa nichrome le li-coil bakeng sa botsitso ba tsona ho fokotseng sepakapaka, ho qoba mathata a kang "ho bola ho tala" ho bonoang li-alloy tse ling9.

 

3. Mekhoa ea Lifofane le Likoloi

Botšepehi ba Nichrome bo atolohela libakeng tse thata tse kang litsamaiso tsa ho tlosa leqhoa moeeng, li-sensor tsa enjene le li-heater tsa cabin.

Ho qhibiliha ha vacuum-induction, mohlala, ho hlahisa limaraka tse kang Ni80Cr20-VI, e ntlafalitsoeng bakeng sa lisebelisoa tsa motlakase tse tšepahalang haholo3. Ho feta moo, karolo ea nichrome lisebelisoa tse bolokang matla le liphahlo tsa spray ea mocheso e totobatsa bokhoni ba eona mekhoeng e tsitsitseng ea indasteri15.

 

Ho Khetha Terata e Nepahetseng ea Nichrome

Ho khetha sehlopha le gauge tse loketseng ho hloka ho lekola mocheso oa ts'ebetso, maemo a tikoloho le litlhaloso tsa motlakase. Lithapo tse tšesaane (gauge e phahameng) li lumellana le litlhoko tse hanyetsanang haholo, ha mefuta e metenya e sebetsana le meroalo e meholo ea hona joale15. Bakeng sa libaka tse feteletseng, nichrome 70 le 80 li fana ka ho tšoarella ho sa bapisoeng, athe nichrome 20 e leka-lekanya litšenyehelo le ts'ebetso bakeng sa li-terminal tsa elektroniki9.

Leha ho hanyetsa mocheso ha nichrome ho fokotsa ditlhoko tsa tlhokomelo, tsamaiso e nepahetseng e ntse e le ya bohlokwa. Ho kenya mocheso, balaodi ba mocheso, le ditlhahlobo tsa kamehla di fokotsa dikotsi tsa ho futhumala ho feteletseng le dikotsi tsa motlakase15. Ho feta moo, nako e telele ya yona le bokgoni ba yona ba ho e sebedisa botjha di tsamaellana le boiteko ba lefatshe ba ho fokotsa ditshila tsa diindasteri.
