Esikhathini lapho ukunemba, ukuqina, kanye nokusebenza kahle kuchaza intuthuko yezimboni,ucingo lwe-nichromeIyaqhubeka nokuma njengesisekelo sokusungula izinto ezintsha ezishisayo. Njengoba yakhiwe ngokuyinhloko yi-nickel (55–78%) kanye ne-chromium (15–23%), enamanani amancane ensimbi kanye ne-manganese, izakhiwo eziyingqayizivele zale alloy ziyenza ibe yinto ebalulekile kuzo zonke izimboni—kusukela ezintweni zasekhaya kuya kubunjiniyela bezindiza. Lapha, sihlola ukusetshenziswa okuhlukahlukene kwentambo ye-nichrome kanye nendima yayo ekwakheni ubuchwepheshe bokushisa besimanje.

 

Izakhiwo Eziyinhloko Eziqhuba Ukuguquguquka kwe-Nichrome

Inani le-Nichrome lisebhalansini layo eliyingqayizivele lezimpawu zomzimba nezikagesi. Njengoba inokumelana okungu-1.0–1.1×10⁻⁶ Ω·m kanye nephuzu lokuncibilika elidlula i-1400°C315, iguqula amandla kagesi abe ukushisa ngempumelelo ngenkathi imelana nokugqwala nokubola ngisho nangaphansi kwezimo ezimbi kakhulu. Uhlobo lwayo olungeyona i-magnetic, ukuguquguquka, kanye nokwanda kokushisa okuphansi kuthuthukisa kakhulu ukuzivumelanisa nezimo kwayo315. Lezi zici ziqinisekisa ukusebenza okuqhubekayo ezindaweni ezifuna ukuthembeka, kusukela ezithandweni zezimboni ezishisa kakhulu kuya kumadivayisi ezokwelapha anembile.

 

Izicelo Eziyinhloko Ze-Nichrome Wire

1. Izinto Zasekhaya

Intambo ye-nichrome iyinsika yamadivayisi okushisa ansuku zonke. Ama-toaster, ama-hair dryer, ama-oven, nama-kettle kagesi athembele emandleni awo okukhiqiza ukushisa okusheshayo nokulinganayo. Isibonelo,i-nichrome 60isetshenziswa kabanzi ezintweni ezisebenzisa ukushisa okumaphakathi njenge-grill kanye nezifudumezi zokugcina izinto, kuyilapho i-nichrome 80 (Ni80Cr20) ihamba phambili ekusetshenzisweni okunamandla kakhulu njengezifudumezi zamanzi kanye nezinsimbi zokugoqa ngenxa yokunamathela kwayo okuphezulu kwe-oxide kanye nokuphila isikhathi eside915.

2. Izinqubo Zezimboni Nezokukhiqiza

Ezindaweni zezimboni, ucingo lwe-nichrome lunika amandla izitofu zikagesi, ama-oven, kanye nemishini yokucubungula ukushisa. Ukumelana kwayo nokukhukhuleka—ukugcina ubuqotho besakhiwo ngaphansi kokucindezeleka isikhathi eside emazingeni okushisa angaphezu kuka-400°C—kwenza kube kuhle kakhulu ekufakweni, ukuncibilikisa, kanye nokwelashwa ngokushisa315. Izimboni ezifana ne-metallurgy kanye ne-ceramics zisebenzisa imichilo ye-nichrome kanye nama-coil ukuze ziqine ekunciphiseni umoya, zigweme izinkinga ezifana “nokubola okuluhlaza” okubonakala kwezinye izinhlobo ze-alloys9.

 

3. Izinhlelo Zezindiza Nezimoto

Ukuthembeka kwe-Nichrome kudlulela ezindaweni ezidinga amandla njengezinhlelo zokususa i-aerospace de-icing, izinzwa zenjini, kanye nezifudumezi zekhabhini. Amandla ayo okumelana nokujikeleza kokushisa kanye nezimo ezinzima aqinisekisa ukuphepha nokusebenza kahle ezingxenyeni ezibalulekile15. Ukusetshenziswa kwezimoto kufaka phakathi izifudumezi zezihlalo kanye nezintambo zokuncibilikisa iqhwa, lapho izinhlobo ze-nichrome 30 kanye ne-40 zinikeza ukufudumala okuhlala isikhathi eside nokonga amandla9.

4. Imishini Yezokwelapha Neyelebhu

Ekunakekelweni kwezempilo, intambo ye-nichrome ivumela ukulawulwa okunembile kokushisa kumathuluzi okuhlinza, ama-heating pad, kanye namadivayisi okubulala amagciwane. Ama-laboratories asebenzisa ukungangeni kwawo ekuhlolweni komlilo kanye nokushiswa okukude kwamakhemikhali asabelayo, okunciphisa izingozi zokungcola715.

5. Izinto Ezintsha Ezisafufusa Nezixazululo Ezingokwezifiso

Intuthuko kuma-alloy e-nichrome igxile ekuthuthukiseni ukusebenza kahle ngokusebenzisa ukwakheka okucwengekile kanye namasu okukhiqiza. Ukuncibilikisa i-vacuum-induction, isibonelo, kukhiqiza amazinga afana ne-Ni80Cr20-VI, elungiselelwe imishini ye-electrothermal enokwethenjelwa kakhulu3. Ngaphezu kwalokho, indima ye-nichrome ezintweni zikagesi ezisebenzisa amandla kahle kanye nezingubo zokufutha ezishisayo iqokomisa amandla ayo emikhubeni yezimboni esimeme15.

 

Ukukhetha Intambo Efanele Ye-Nichrome

Ukukhetha ibanga elifanele kanye negeyiji kudinga ukuhlola amazinga okushisa okusebenza, izimo zemvelo, kanye nemininingwane kagesi. Izintambo ezincane (igeyiji ephezulu) zifanelana nezidingo zokumelana okuphezulu, kuyilapho izinhlobo ezijiyile zisingatha imithwalo yamanje emikhulu15. Ezindaweni ezibucayi, i-nichrome 70 kanye ne-80 zinikeza ukuqina okungenakuqhathaniswa, kanti i-nichrome 20 ilinganisa izindleko kanye nokusebenza kwama-terminal kagesi9.

 

Izinto Ezicatshangelwayo Zokuphepha Nokuzinza

Nakuba ukumelana nokushisa kwe-nichrome kunciphisa izidingo zokunakekelwa, ukuphathwa kahle kusabalulekile. Ukushisa, abalawuli bokushisa, kanye nokuhlolwa okuvamile kunciphisa izingozi zokushisa ngokweqile kanye nezingozi zikagesi15. Ngaphezu kwalokho, ukuhlala kwayo isikhathi eside kanye nokusetshenziswa kabusha kwayo kuhambisana nemizamo yomhlaba wonke yokunciphisa imfucuza yezimboni.

 

Mayelana Nenkampani Yethu
Njengomholi ezixazululweni ze-alloy ezithuthukisiwe, sigxile ekukhiqizeni izintambo ze-nichrome ezisebenza kahle kakhulu ezenzelwe izinhlelo zokusebenza ezahlukahlukene. Izikhungo zethu zesimanje zisebenzisa ubunjiniyela obunembile kanye nokulawulwa kwekhwalithi okuqinile ukuze zilethe ama-alloy adlula amazinga embonini. Kusukela ezintweni zokushisa zezinga lendiza kuya ekwakhiweni kwe-resistor ngokwezifiso, imikhiqizo yethu iqhuba ukusungula izinto ezintsha kuyo yonke imikhakha.

Ukuguquguquka okungenakuqhathaniswa kwe-Nichrome wire kuqinisa isimo sayo njengento ebalulekile kwezobunjiniyela besimanje. Njengoba izimboni zithuthuka, nezinhlelo zokusebenza zayo zizothuthuka—eziqhutshwa yintuthuko kwesayensi yezinto ezibonakalayo kanye nokuzibophezela ekusimeni. Ukuze uthole izixazululo ze-nichrome ezenzelwe wena ezihlangabezana nezidingo zakho zobuchwepheshe nezokusebenza, xhumana nethimba lethu namuhla.
