Ukushisa kuyisinyathelo esiyisisekelo kodwa esibalulekile ezicini eziningi zokukhiqiza izimboni. Kusukela ekwelashweni kokushisa kwensimbi kuya ekushiseni i-ceramic, ngisho nasekucutshungulweni kwezinto ezithile ezikhethekile, kudingeka imishini yokushisa ezinzile, esebenza kahle, nevumelana nezimo. Kulezi zimo ezinezidingo eziqinile zokushisa nokuqina,imisebe ye-silicon carbideAmashubhu aseba ukukhetha kwamabhizinisi amaningi ngenxa yezinzuzo zawo eziyingqayizivele.
Abanye abantu bangase babe nesithakazelo, iyini ithubhu yemisebe ye-silicon carbide? Kalula nje, iyisakhi sokushisa esiyi-tubular esenziwe kakhulu nge-silicon carbide ceramics, evame ukusetshenziswa kanye nezintambo zokushisa, izinduku zokushisa kanye nezinye izinhliziyo zangaphakathi, futhi idlala indima "yokushintshanisa ukushisa" kuma-oven ezimboni kanye neminye imishini. Kodwa-ke, ukuhluka kwayo kulele ekutheni ayikhiqizi ngokuqondile amazinga okushisa aphezulu, kodwa kunalokho idlulisela ngokulinganayo ukushisa endaweni yokusebenza edinga ukufudunyezwa ngesimo semisebe ngokusebenzisa izinto zokushisa zangaphakathi ezizungezile, kuyilapho futhi ivikela izingxenye zangaphakathi emoyeni oyinkimbinkimbi ngaphakathi kwe-oven.
Uma kukhulunywa ngezinzuzo zamashubhu emisebe ye-silicon carbide, "ukumelana nokushisa okuphezulu" ngokuqinisekile kuyilebula eliyinhloko lawo. Amashubhu okushisa ensimbi ajwayelekile angase abhekane nokuguquguquka kanye nokushiswa emazingeni okushisa angamakhulu amaningana degrees Celsius, kuyilapho ama-silicon carbide ceramics ngokwawo enokumelana okuhle kakhulu nokushisa okuphezulu. Ngisho nasezitsheni zokushisa eziphakeme ezingaphezu kuka-1300 ℃, angagcina ukuqina kwesakhiwo futhi awonakaliswa kalula. Lesi sici sivumela ukuthi ivumelane nezimo eziningi zokucubungula izinga lokushisa eliphezulu, njengokushisa kokushisa kwezinye izitsha ezikhethekile ezivame ukudlula u-1200 ℃, kanye namashubhu emisebe ye-silicon carbide angasebenza ngokuthembekile ezindaweni ezinjalo isikhathi eside.
Ngaphezu kokumelana nokushisa okuphezulu, "ukumelana nokugqwala" nakho kuyisici esivelele kakhulu. Ezinqubweni eziningi zokushisa zezimboni, kungase kube namagesi ane-asidi, i-alkaline noma ezinye izinto ezigqwalisayo kuhhavini, ezingagqwala kalula izinto ezifudumezayo futhi zifinyeze impilo yesevisi yemishini. Ukuqina kwamakhemikhali kwezinto ze-silicon carbide kunamandla, futhi akulula ukusabela ngalezi zinto ezigqwalisayo, okusho ukuthi ingagcina ukuqina okuhle ezindaweni eziyinkimbinkimbi zehhavini, inciphise imvamisa yokushintsha imishini, futhi ngokuhamba kwesikhathi, inciphise nezindleko zokukhiqiza nokugcina amabhizinisi.
Ngaphezu kwalokho, "ukusebenza kahle kokushisa" kwamashubhu emisebe ye-silicon carbide nakho kufanelekile ukukusho. Ukushisa kwayo kuhle, okungadlulisa ngokushesha ukushisa okukhiqizwa yizinto zokushisa zangaphakathi futhi kushise umsebenzi ngemisebe. Le ndlela yokushisa ayigcini nje ngokushisa ngokushesha, kodwa futhi yenza ukusatshalaliswa kokushisa ngaphakathi kwesitofu kufane kakhulu, kugweme ukushisa ngokweqile kwendawo noma izinga lokushisa elanele. Lokhu kubaluleke kakhulu ekuqinisekiseni ukuhambisana kwekhwalithi yokucubungula umkhiqizo. Isibonelo, ekwelashweni kokushisa kwezingxenye zensimbi, ukufana kokushisa kuthinta ngqo ubulukhuni, ukuqina, nezinye izakhiwo zezingxenye, futhi amashubhu emisebe ye-silicon carbide anganikeza ukwesekwa okuzinzile kulokhu.
Yiqiniso, ukusetshenziswa kwamashubhu emisebe ye-silicon carbide akunamingcele. Isibonelo, izindleko zawo ziphakeme kakhulu kunezamashubhu okushisa ensimbi ajwayelekile, futhi ngenxa yezici zezinto zobumba, kudingeka agweme ukushayisana okukhulu ngesikhathi sokufakwa nokusetshenziswa ukuvimbela umonakalo. Kodwa ezimbonini ezinezidingo eziphezulu zokushisa, ukugqwala kwemvelo, kanye nekhwalithi yomkhiqizo, ukuzinza, ukusebenza kahle, kanye nokuphila isikhathi eside okulethayo kuvame ukukhokhela lezi zingqinamba ezincane.
Namuhla, njengoba intuthuko yokukhiqiza izimboni ibheke ekuqondeni okukhulu kanye nekhwalithi ephezulu, izidingo zemishini yokushisa nazo ziyanda njalo. Njengento enhle kakhulu yokushisa izimboni, amashubhu emisebe ye-silicon carbide adlala indima enkulu kancane kancane emikhakheni efana ne-ceramics, i-metallurgy, kanye ne-electronics. Kungase kungabi yinto ekhangayo njengeminye yezobuchwepheshe obusha, kodwa yilo kanye lolu hlobo "lokunamathela endaweni yalo" buthule ezindaweni ezibucayi okwenza kube "uchwepheshe omelana nokushisa okuphezulu" obalulekile ekukhiqizeni izimboni, okunikeza iziqinisekiso ezithembekile zezinqubo ezahlukene zokushisa ezifunwa kakhulu.
