Lapho usesha ozongena esikhundleni seintambo ye-nichrome, kubalulekile ukucabangela izici ezibalulekile ezenza i-nichrome ibaluleke kakhulu: ukumelana nezinga lokushisa eliphezulu, ukumelana nogesi okungaguquki, ukumelana nokugqwala, nokuqina. Nakuba izinto ezimbalwa zisondela, azikho ezifana nebhalansi ehlukile ye-nichrome yokusebenza—okwenza imikhiqizo yethu yentambo ye-nichrome ibe ukukhetha okuthembekile kwezinhlelo zokusebenza ezibalulekile.
Enye indlela evamile i-kanthal wire, iingxubevange ye-iron-chromium-aluminium. I-Kanthal iphumelela kakhulu ezindaweni ezinezinga eliphezulu lokushisa, imelana nezinga lokushisa elifika ku-1,400°C, eliphakeme kunamanye amabanga e-nichrome. Nokho, inhlakanhlaka futhi ayithandeki kangako, okwenza kube nzima ukubumba imiklamo eyinkimbinkimbi. Kuzinhlelo zokusebenza ezidinga ukuguquguquka, njengama-elementi amancane okushisa ku-elekthronikhi, i-kanthal ivamise ukuwa, kanti i-ductility ye-nichrome ivumela ukwakheka okunembayo ngaphandle kokuqhekeka.
I-Copper-nickel (Cu-Ni) wire ingenye imbangi, enenani ngenxa yokumelana nokugqwala kanye nokumelana okumaphakathi. Kodwa i-Cu-Ni idonsa kanzima emazingeni okushisa aphezulu, ifaka i-oxidizing ngokushesha ngaphezu kuka-300°C, okukhawulela ukusetshenziswa kwayo ezimeni ezishisa kakhulu njengeziko lezimboni noma amakhoyili okushisa. I-Nichrome, ngokuphambene, igcina ukuzinza ngisho naku-1,200°C, iyenze ibe nezinto ezihlukahlukene kakhulu emisebenzini yezinga lokushisa eliphezulu.
Intambo ye-Tungsten inikeza ukumelana nokushisa okukhethekile, imelana namazinga okushisa afika ku-3,422°C. Nokho, i-brittle ngokwedlulele futhi inokumelana nogesi okuphansi, okudinga amaza aphezulu ukuze ikhiqize ukushisa. Lokhu kwenza kungenzeki ezinsizeni eziningi zokushisisa lapho ukusebenza kahle kwamandla kanye nokusebenziseka kalula kuyindaba—izindawo lapho i-nichrome, enokumelana kwayo okuhle nokusebenza kwayo, ikhanya khona.
Intambo yensimbi engagqwali ivame ukucatshangelwa ukuthi ifinyeleleke kalula futhi ingagqwali. Nokho, inokumelana okuphansi kune-nichrome, okusho ukuthi ikhiqiza ukushisa okuncane ngobude beyunithi ngayinye, edinga ama-gauge ashubile noma ama-voltage aphezulu ukuze afane nokukhiphayo kwe-nichrome. Ngokuhamba kwesikhathi, insimbi engagqwali nayo ijwayele ukonakala ngaphansi kokushisa okude, inciphise ubude bayo bempilo uma iqhathaniswa nokuzinza kwesikhathi eside kwe-nichrome.
Imikhiqizo yethu yezintambo ze-nichrome ibhekana nale mikhawulo yezinto ezithatha indawo. Itholakala emabangeni ahlukene (njengeI-NiCr 80/20), zinikeza ukumelana okunembile kokukhipha ukushisa okungaguquki, i-ductility enhle kakhulu yokwenza lula, nokumelana ne-oxidation ephakeme emazingeni okushisa aphezulu. Kungakhathaliseki ukuthi okokushisisa ezintweni zikagesi, izinto zaselabhorethri, noma iziko lemboni, izintambo zethu ze-nichrome ziletha ukusebenza okuthembekile, ukonga amandla, nokuqina okunye okunzima ukukuphindaphinda.
Ukukhetha intambo efanele kusho ukubeka phambili inhlanganisela eyingqayizivele yezakhiwo ezihlinzekwa yi-nichrome kuphela. Imikhiqizo yethu iklanyelwe ukuhlangabezana nezindinganiso eziqinile zekhwalithi, iqinisekisa ukuthi idlula okunye esikhundleni kukho kokubili ukusebenza nokuphila isikhathi eside—okuyenza ibe ukukhetha okuhlakaniphile kwezidingo zakho zokushisisa.
