Incazelo Yomkhiqizo
Lezi zintambo eziqinile zokumelana zisetshenziswe kabanzi kuma-resistors ajwayelekile, imoto
izingxenye, izinqamuleli ezimazombezombe, njll. kusetshenziswa ukucubungula kwe-insulation ezifaneleka kakhulu lezi zinhlelo zokusebenza, kusizakala ngokugcwele izici ezihlukile zokumbozwa koqweqwe lwawo.
Ngaphezu kwalokho, sizokwenza ukwahlukanisa koqweqwe lwawo koqweqwe lwawo lwezintambo zensimbi eziyigugu njengesiliva neplatinamu uma ku-oda. Sicela usebenzise lokhu kukhiqiza-on-oda.

I-nicr8020 i-alloy heat wire
1.Mayelana nocingo lwe-Nichrome
I-Nichrome alloy ihlanganisa i-pure nickel, i-NiCr alloy, i-Fe-Cr-Al alloy ne-copper nickel alloy.
Ama-alloys e-nickel chrome: Ni80Cr20, Ni70Cr30, Ni60Cr15, Ni35Cr20, Ni30Cr20, Cr25Ni20, nickel Ni200 neNi201
2.Inzuzo Eyinhloko kanye Nesicelo
1. I-Nickel-chromium, i-nickel-chromium alloy enokumelana okuphezulu nokuzinzile, ukumelana nokugqwala, ukumelana ne-oxidation ebusweni kuhle, okungcono ngaphansi kwezinga lokushisa eliphezulu namandla okuzamazama komhlaba, i-ductility enhle, ukusebenza kahle nokushisela.
2.Imikhiqizo yethu isebenza kakhulu embonini yamakhemikhali, indlela yokwenza insimbi, imboni yengilazi, imboni ye-ceramic, indawo yezinto zikagesi zasendlini nokunye.
