Ungayikhetha kanjani into yokushisa yesithando somlilo?

Into yokushisa yesithando somlilo ngokuvamile iyinduku ye-silicon carbide noma induku ye-silicon molybdenum. Isici se-silicon molybdenum rod resistive heat element is a high temperature resistant and oxidation resistant resistance element eyenziwe ngesisekelo se-molybdenum disilicide. Uma isetshenziswa endaweni enezinga lokushisa eliphezulu lokushisa, ifilimu yengilazi ekhanyayo futhi eminyene (SiO2) yakhiwa ngaphezulu, engavikela ungqimba lwangaphakathi lwensimbi ye-silicon molybdenum kusuka ku-oxidation. Ngakho-ke, isici se-silicon molybdenum rod sinokumelana okuhlukile kokushisa okuphezulu kokushisa.

Esimweni se-oxidizing, izinga lokushisa elisebenza kakhulu lingu-1800 ° C. Ukumelana kwento yokushisa ye-silicon molybdenum yanda ngokushesha ngokukhuphuka kwezinga lokushisa, futhi inani lokumelana lizinzile lapho izinga lokushisa lingaguquki. Ngaphansi kwezimo ezijwayelekile, ukumelana kwento leyo akuguquki nobude besikhathi sokusetshenziswa. Ngakho-ke, izinto zokushisa zikagesi ezindala nezintsha zingahlanganiswa.

Ngokwesakhiwo, ukusebenza komkhathi nokushisa kwemishini yokushisa, ukukhethwa okulungile komthwalo ongaphezulu wento yokushisa kagesi kuyisihluthulelo sempilo yesevisi yento yokushisa kagesi ye-silicon molybdenum.
