I-Alicon Carbide ceramicsIngabe izinto ezibalulekile ezingxenyeni eziningi zezimboni ngenxa yezakhiwo zazo ezihlukile, kufaka phakathi ubunzima obuphezulu, nobunzima obuphansi kanye nokumelana okuhle kakhulu. Lezi zakhiwo zenza i-silicon Carbide (Sic) ukukhetha okuhle kwezicelo ku-Mechanical Engineering, amakhemikhali kanye nezimboni zensimbi, amakhilogremu ezimboni kanye nemishini ehlukahlukene yokushisa. Le ndatshana ithatha ukujula okujulile ekusetshenzisweni okuningi kwe-aricon carbide ceramics, kugqamisa ukubaluleka kwako ezinhlanganweni zanamuhla zokukhiqiza nezimboni.
Emkhakheni wobunjiniyela bemishini, ama-ceramics e-silicon carbiide aya ngokuya esetshenziswa ngenxa yobulukhuni bawo obuhle futhi agqoke ukumelana. Lezi zinto zokwenziwa zilungele ikakhulukazi ukukhiqiza izinto ezincane ezifaka ukufakwa kanye nokugqoka izingxenye ezidinga ukuqina kanye nokwethenjwa. I-Silicon Carbide ingamelana namazinga okushisa aphezulu ngaphandle kokulimaza noma ilahlekelwe ubuqotho besakhiwo, okwenza ilungele ukusetshenziswa emishini yokusebenza ephezulu. Njengoba imboni iyaqhubeka nokufuna izingxenye ezisebenza kahle futhi ezihlala isikhathi eside, iqhaza le-airbide ceramics ye-silicon carbiide ku-Mechanical Engineering kulindeleke ukuthi yandise kakhulu.
Izimboni zamakhemikhali nezinsimbi ziye zazuza kakhulu kusuka ku-arbide ceramics ye-silicon. Lezi zinto zokwenziwa zinokumelana kahle nokugqwayiza okuhle kakhulu, ikakhulukazi ukuncibilikisa i-iron, i-slag kanye ne-alkali. Le mpahla ibalulekile ezindaweni lapho izinto zendabuko zizokwehluleka, kuholele ekutheni kube nezikhathi ezibizayo nokulungisa. Ngokuphawulekile, ngaphezu kwama-65% wezinto ezinkulu zokuqhuma komhlaba wonke zisebenzisa izinto ze-silicon nitride-bonded silicon carbide izinto njengezinto zokwenziwa zomzimba. Lolu hlelo lokusebenza alugcini nje kuphela lwenkonzo yenkonzo yokuqhuma kwe-blast ngo-20- 40%, kepha futhi kuthuthukisa ukusebenza kahle okusebenzayo. Ngaphezu kwalokho, ama-ceramics e-silicon carbiide nawo asetshenziswa njengezinsimbi zomlilo kanye nama-errucles wokubhema insimbi njenge-aluminium, ithusi kanye ne-zinc, okukhombisa ukuguquguquka kwayo kwezicelo eziphakeme kakhulu.
Kuma-kilns wezimboni, ama-ailbito Carbide ceramics adlala indima ebalulekile ekwakheni kahle ukusebenza kanye nokusebenza kwamandla. Ukusetshenziswa kwefenisha ye-Silicon Carbide Kiln Kiln kunganciphisa kakhulu isisindo kanye nezidingo zesikhala, ezizuzisa kakhulu ezimbonini ezinjengemboni elikhanyayo, izinto zokwakha kanye ne-elekthronikhi. Isisindo esikhanyayo sezakhi ze-silicon Carbide sisiza ukuthuthukisa ukusetshenziswa kwamandla ngoba amandla amancane adingekayo ukushisa i-kiln. Ngaphezu kwalokho, ukumelana nomthelela omuhle kakhulu wezinto zokwenziwa ze-karbide we-silicon kuvumela izinga lokushisa lokudubula likhuphuke ngokushesha, ngcono ukuthuthukisa ukusebenza kahle kokusebenza kwe-kiln.
I-Alicon Carbide ceramics nayo ihlanganiswe kumadivayisi ahlukahlukene wokushisa asetshenziselwa ukukhonkotha, ukuncibilika, nokushisa izinto zokwelapha. Ukushisa okungaqondile ngegesi sekuyindlela ekhethwayo kulezi zinqubo ngoba kunika amandla ukusebenza kahle okushisayo ngenkathi kunciphisa ukuphuma okulimazayo, njenge-nitrogen oxides (nox). Ukusetshenziswa kwe-silicon Carbide kula madivaysi okushisa akugcini nje ngokuthuthukisa ukusebenza kodwa futhi kuhambisana nemizamo yembulunga yonke yokunciphisa umthelela wezemvelo. Njengoba izimboni zilwela izisombululo ezinobungane ngokwemvelo, isidingo se-silicon Carbide ceramics yezinhlelo zokushisa kungenzeka ukuthi sikhule.
Ukuguquguquka okuhlukahlukene kwe-alimacon carbide ceramics kudlulela ngale kwezicelo zendabuko njengoba ziya ngokuya zisetshenziswa kubuchwepheshe obuthuthukile. Isibonelo, emkhakheni we-elekthronikhi, iSilicon Carbide isetshenziswa ekukhiqizweni kwamadivayisi we-semiconductors kanye namandla. Ukuvuselelwa okuphezulu okushisayo kanye nezindawo zokufakwa kukagesi ze-Silicon Carbide zenze ilungele imvamisa ephezulu kanye nezicelo ezishisa kakhulu ze-elekthronikhi. Njengoba izidingo ze-elekthronikhi ezisebenza kahle nezinokwethenjelwa ziqhubeka zikhula, kulindeleke ukuthi ama-ceramics carbiide carbiide kulindeleke ukuthi adlale indima ebalulekile ekukhiqizweni kwe-elekthronikhi okuzayo.
Ngaphezu kwalokho, izimboni ze-aerospace nezezimoto ziqala ukubona amandla e-silicon carbide ceramic yezakhi ezingasindi, ezinamandla anamandla. Amandla ka-Silicon Carbide wokubekezelela amazinga okushisa aphezulu nezindawo ezinokhahlo kwenza kube inketho ekhangayo yezicelo ezinjenge-turbine blades, ama-brake disc, nezinye izinto ezibucayi. Njengoba lezi zimboni zifuna ukuthuthukisa ukusebenza kahle kaphethri futhi zinciphise ukuphuma kwama-ceramics, okufaka ama-ceramic we-silicon carbide emiklamo yazo kungathuthukisa kakhulu ukusebenza nokusimama.
Ngamafuphi, ukusetshenziswa kwe-arbide ceramics ye-silicon carbiide kuhamba ngobanzi, ngenxa yezakhiwo zazo ezihlukile nezinzuzo zokusebenza. Kusuka kunjiniyela wemishini ukucubungula kwamakhemikhali, ama-kilns wezimboni kanye nama-elekthronikhi athuthukile, ama-ceramics e-silicon Carbidis afakazele ukuthi yingxenye ebaluleke kakhulu yokwenziwa kwanamuhla. Njengoba ubuchwepheshe buqhubeka buqhubekisa phambili, kungenzeka ukuthi i-arbidon carbide ceramic ukufaka isandla kwizixazululo ezintsha kanye nemikhuba esinzile izokwanda kuphela. Ikusasa le-weramics ye-silicon Carbide yethembisa, futhi ukuqhubeka kokucwaninga nentuthuko kuqhubekela phambili ngendlela yezinhlelo zokusebenza ezintsha nokusebenza okuthuthukisiwe emikhakheni ehlukahlukene.
