i-kanthal a1 ekhanyayo noma i-oxidation fecral alloy wire

Kanthal A1isetshenziswa emazingeni okushisa afinyelela ku-1400°C (2550°F). Lolu hlobo lwe-Kanthal luyisinqumo esingcono kakhulu socingo lokumelana nezicelo ezinkulu zezimboni. Iphinde ibe namandla okuqina aphakeme kancane kunawoKanthal D.

Sine stock, uma udinga, sicela usithinte ngokushesha.

Kanthal A1isetshenziswa kakhulu ekushisiseni izinto ezinhlelweni ezinkulu zezimboni ezifana neziko lezimboni (ezivamise ukutholakala kungilazi, izitsha zobumba, zikagesi, nezimboni zensimbi). I-resistivity yayo ephezulu kanye nekhono lokumelana nezakhi ngaphandle kwe-oxidation, ngisho nasezimo zezulu zesulfuric nezishisayo, kwenza i-Kanthal A1 ibe yinketho ethandwayo lapho isebenza ngezinto zokushisa ezinkulu. Intambo ye-Kanthal A1 futhi inokumelana nokugqwala okumanzi okuphezulu namandla aphakeme ashisayo nokunwabuzelayoKanthal D, okwenza kube ukukhetha okudumile kwezinhlelo zokusebenza zezimboni ezinkulu.

I-Kanthal wire iyingxube ye-ferritic iron-chromium-aluminium (FeCrAl). Ayigqwali kalula noma ayifaki i-oxidize ezinhlelweni zemboni futhi inokumelana okuhle kakhulu nezinto ezibolayo.

I-Kanthal wire inezinga lokushisa eliphezulu eliphezulu lokusebenza kunentambo ye-Nichrome. Uma iqhathaniswa ne-Nichrome, inomthwalo ongaphezulu kwendawo, ukumelana okuphezulu, amandla esivuno esiphezulu, kanye nokuminyana okuphansi. I-Kanthal wire futhi ihlala izikhathi ezi-2 kuya kwezi-4 ubude kunocingo lwe-Nichrome ngenxa yezakhiwo zayo eziphezulu ze-oxidation kanye nokumelana nezindawo zesulfuric.
