Izitsha zobumba ze-silicon carbideziyizinto ezibalulekile ezinhlobonhlobo zezimboni ngenxa yezakhiwo zazo ezihlukile, okuhlanganisa ubulukhuni obuphezulu, ukuminyana okuphansi kanye nokumelana nokushisa okuhle kakhulu. Lezi zakhiwo zenza i-silicon carbide (SiC) ibe yisinqumo esifanele sokusetshenziswa kwezobunjiniyela bemishini, izimboni zamakhemikhali nezensimbi, ama-oven ezimboni kanye nemishini ehlukahlukene yokushisa. Lesi sihloko sibheka ngokujulile ukusetshenziswa okuningi kwe-silicon carbide ceramics, sigcizelela ukubaluleka kwazo ekukhiqizeni kwesimanje kanye nezinqubo zezimboni.
Emkhakheni wobunjiniyela bemishini, izitsha ze-silicon carbide zisetshenziswa kakhulu ngenxa yobunzima bazo obuhle kakhulu kanye nokumelana nokuguguleka. Lezi zinto zifaneleka kakhulu ekukhiqizeni izingxenye ezincane zokuvikela kanye nezingxenye zokuguga ezidinga ukuqina nokuthembeka. I-Silicon carbide ingamelana namazinga okushisa aphezulu ngaphandle kokushintsha noma ukulahlekelwa ubuqotho besakhiwo, okwenza kube kuhle ukusetshenziswa emishinini esebenza kahle kakhulu. Njengoba imboni iqhubeka nokudinga izingxenye ezisebenza kahle nezihlala isikhathi eside, indima yezitsha ze-silicon carbide kubunjiniyela bemishini kulindeleke ukuthi ikhule kakhulu.
Izimboni zamakhemikhali nezensimbi nazo zizuze kakhulu nge-silicon carbide ceramics. Lezi zinto zinokumelana okuhle kakhulu nokugqwala, ikakhulukazi ensimbini encibilikisiwe, i-slag kanye ne-alkali metals. Lesi sici sibaluleke kakhulu ezindaweni lapho izinto zendabuko zizohluleka khona, okuholela esikhathini esibi kakhulu sokungasebenzi kanye nokugcinwa. Okuphawulekayo ukuthi, ngaphezu kwama-65% ezitofu ezinkulu zokuqhuma emhlabeni wonke zisebenzisa izinto ze-silicon carbide eziboshwe yi-silicon nitride njengezinto zomzimba wesitofu. Lokhu kusetshenziswa akugcini nje ngokwandisa impilo yesevisi yezitofu zokuqhuma ngo-20-40%, kodwa futhi kuthuthukisa ukusebenza kahle. Ngaphezu kwalokho, izitofu ze-silicon carbide nazo zisetshenziswa njengezinto zokuhlobisa isitofu kanye nezinto zokuncibilikisa insimbi njenge-aluminium, ithusi kanye ne-zinc, okubonisa ukuguquguquka kwayo ekusetshenzisweni kwezinga lokushisa eliphezulu.
Ezitsheni zokushisa zezimboni, i-silicon carbide ceramics idlala indima ebalulekile ekwenzeni ngcono ukusebenza kahle kwamandla. Ukusetshenziswa kwefenisha ye-silicon carbide kiln kunganciphisa kakhulu isisindo nezidingo zesikhala, okuzuzisa kakhulu izimboni ezifana nezimboni ezilula, izinto zokwakha kanye ne-elekthronikhi. Isisindo esincane sezingxenye ze-silicon carbide sisiza ekuthuthukiseni ukusetshenziswa kwamandla ngoba kudingeka amandla amancane ukushisa i-kiln. Ngaphezu kwalokho, ukumelana okuhle kakhulu komthelela wezinto ze-silicon carbide kuvumela izinga lokushisa lokudubula likhuphuke ngokushesha, okuqhubeka nokuthuthukisa ukusebenza kahle kwe-kiln.
I-silicon carbide ceramics nayo iyingxenye ebalulekile kumadivayisi ahlukahlukene okushisa asetshenziselwa ukuthulula, ukuncibilikisa, kanye nokwelapha ukushisa. Ukushisa okungaqondile ngegesi sekuyindlela ekhethwayo kulezi zinqubo ngoba kwenza kube nokusebenza kahle kokushisa okuthuthukisiwe ngenkathi kunciphisa ukukhishwa okuyingozi, njenge-nitrogen oxides (NOx). Ukusetshenziswa kwe-silicon carbide kula madivayisi okushisa akugcini nje ngokuthuthukisa ukusebenza kodwa futhi kuhambisana nemizamo yomhlaba wonke yokunciphisa umthelela emvelweni. Njengoba izimboni zilwela izixazululo ezinobungani nemvelo, isidingo se-silicon carbide ceramics sezinhlelo zokusebenza zokushisa cishe sizokhula.
Ukuguquguquka kwe-silicon carbide ceramics kudlulela ngale kwezicelo zendabuko njengoba zisetshenziswa kakhulu kwezobuchwepheshe obuthuthukisiwe. Isibonelo, emkhakheni we-elekthronikhi, i-silicon carbide isetshenziswa ekukhiqizweni kwama-semiconductors namadivayisi kagesi. Ukushisa okuphezulu kanye nezakhiwo zokushisa zikagesi ze-silicon carbide kwenza kube kuhle kakhulu ekusetshenzisweni kwe-elekthronikhi okuvama kakhulu kanye nokushisa okuphezulu. Njengoba isidingo sezingxenye ze-elekthronikhi ezisebenzayo nezithembekile siqhubeka nokukhula, kulindeleke ukuthi i-silicon carbide ceramics idlale indima ebalulekile ekukhiqizweni kwe-elekthronikhi esikhathini esizayo.
Ngaphezu kwalokho, izimboni zezindiza kanye nezimoto seziqala ukuqaphela amandla e-silicon carbide ceramics ezingxenyeni ezilula nezinamandla aphezulu. Ikhono le-silicon carbide lokubekezelela amazinga okushisa aphezulu kanye nezimo ezinzima lenza kube inketho ekhangayo yezinhlelo zokusebenza ezifana nama-turbine blades, ama-brake disc, nezinye izingxenye ezibalulekile. Njengoba lezi zimboni zifuna ukuthuthukisa ukusebenza kahle kukaphethiloli nokunciphisa ukukhishwa kwegesi, ukufaka i-silicon carbide ceramics emiklamo yazo kungathuthukisa kakhulu ukusebenza kanye nokusimama.
Ngamafuphi, ukusetshenziswa kwe-silicon carbide ceramics kubanzi, ngenxa yezakhiwo zazo ezihlukile kanye nezinzuzo zokusebenza. Kusukela kubunjiniyela bemishini kuya ekucutshungulweni kwamakhemikhali, ama-oven ezimboni kanye ne-elekthronikhi ethuthukisiwe, i-silicon carbide ceramics ibonakale iyingxenye ebalulekile yokukhiqiza kwesimanje. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, amathuba e-silicon carbide ceramics okufaka isandla ezixazululweni ezintsha kanye nemikhuba eqhubekayo azokhula kuphela. Ikusasa le-silicon carbide ceramics liyathembisa, futhi ucwaningo oluqhubekayo kanye nentuthuko luvula indlela yezinhlelo zokusebenza ezintsha kanye nokusebenza okuthuthukisiwe emikhakheni eyahlukahlukene.
