Uma ufuna indawo esikhundleni salokhoucingo lwe-nichrome, kubalulekile ukucabangela izakhiwo eziyinhloko ezenza i-nichrome ibe yinto ebalulekile: ukumelana nokushisa okuphezulu, ukumelana nogesi okuqhubekayo, ukumelana nokugqwala, kanye nokuqina. Nakuba izinto eziningana zisondela, azikho ezilingana nokulinganisela okuyingqayizivele kokusebenza kwe-nichrome—okwenza imikhiqizo yethu ye-nichrome wire ibe ukukhetha okuthembekile kwezicelo ezibalulekile.
Enye indlela evamile i-kanthal wire,i-iron-chromium-aluminium alloyI-Kanthal iphumelela kakhulu ezindaweni ezishisa kakhulu, ibekezelela amazinga okushisa afinyelela ku-1,400°C, okuphakeme kunezinye izinhlobo ze-nichrome. Kodwa-ke, iyaphuka kalula futhi ayiguquguquki, okwenza kube nzima ukuyibumba ibe yimiklamo eyinkimbinkimbi. Ezinhlelweni ezidinga ukuguquguquka, njengezinto ezincane zokushisa kuma-elekthronikhi, i-kanthal ivame ukwehluleka, kanti ukuguquguquka kwe-nichrome kuvumela ukwakheka okunembile ngaphandle kokuqhekeka.
Intambo ye-Copper-nickel (Cu-Ni) ingenye into ephikisana nayo, ebaluleke kakhulu ngenxa yokumelana kwayo nokugqwala kanye nokumelana kwayo okulinganiselwe. Kodwa i-Cu-Ni iyahluleka emazingeni okushisa aphezulu, i-oxidize ngokushesha ngaphezu kwama-300°C, okunciphisa ukusetshenziswa kwayo ezimweni zokushisa okuphezulu njengezitofu zezimboni noma ama-heating coils. I-Nichrome, ngokuphambene nalokho, igcina ukuzinza ngisho naku-1,200°C, okwenza ibe nokuguquguquka okukhulu emisebenzini yokushisa okuphezulu.
Ucingo lwe-tungsten lunikeza ukumelana nokushisa okumangalisayo, lubekezelela amazinga okushisa aphezulu afinyelela ku-3,422°C. Kodwa-ke, luthambile kakhulu futhi lunamandla okumelana kagesi aphansi, ludinga amaza aphezulu ukuze kukhiqizwe ukushisa. Lokhu kwenza kube nzima kakhulu ekusetshenzisweni okuningi kokushisa lapho ukusebenza kahle kwamandla kanye nokulula kokusetshenziswa kubalulekile—izindawo lapho i-nichrome, enokumelana kwayo okuhle nokusebenza kahle, ikhanya khona.
Ucingo lwensimbi engagqwali luvame ukubhekwa njengolungabizi kakhulu kanye nokumelana nokugqwala. Noma kunjalo, lunamandla aphansi okumelana ne-nichrome, okusho ukuthi lukhiqiza ukushisa okuncane ngobude beyunithi ngayinye, okudinga ama-gauge amakhulu noma ama-voltage aphezulu ukuze afane nomkhiqizo we-nichrome. Ngokuhamba kwesikhathi, insimbi engagqwali nayo ivame ukuguquka lapho ishisa isikhathi eside, okunciphisa isikhathi sayo sokuphila uma kuqhathaniswa nokuzinza kwesikhathi eside kwe-nichrome.
Imikhiqizo yethu ye-nichrome wire ibhekana nale mikhawulo yezinye izinto ezingasetshenziswa esikhundleni sazo. Itholakala ngamamaki ahlukahlukene (njengeI-NiCr 80/20), zinikeza ukumelana okunembile kokukhipha ukushisa okuhambisanayo, ukuguquguquka okuhle kakhulu kokwenziwa kalula, kanye nokumelana okuphezulu kwe-oxidation emazingeni okushisa aphezulu. Kungakhathaliseki ukuthi kunezinto zokushisa ezisetshenziswayo, imishini yelabhorethri, noma izitofu zezimboni, ucingo lwethu lwe-nichrome lunikeza ukusebenza okuthembekile, ukusebenza kahle kwamandla, kanye nokuqina okunzima ukukuphinda kwezinye izindlela.
Ukukhetha ucingo olufanele kusho ukubeka phambili inhlanganisela eyingqayizivele yezakhiwo ezinikezwa yi-nichrome kuphela. Imikhiqizo yethu yakhelwe ukuhlangabezana nezindinganiso zekhwalithi eziqinile, ukuqinisekisa ukuthi isebenza kahle kakhulu kunezinye esikhundleni sayo kokubili ukusebenza kanye nokuphila isikhathi eside—okuyenza ibe ukukhetha okuhlakaniphile kwezidingo zakho zokushisa.
