I-Reaction-sintered silicon carbide ceramic

I-Reaction-sintered silicon carbide ceramic, eyaziwa nangokuthi i-RS-SiC, iyimpahla yobumba ethuthukisiwe eye yadonsa ukunaka okusabalele ngenxa yokusebenza kwayo okuhle kakhulu kanye nobubanzi bezinhlelo zokusebenza. Lezi zitsha zobumba zikhiqizwa ngenqubo ebizwa ngokuthi i-reactive sintering, ehlanganisa ukusabela kwe-carbon ne-silicon emazingeni okushisa aphezulu ukuze kwakhiwe i-silicon carbide. Impahla ewumphumela inezakhiwo ezinhle kakhulu zemishini, ezishisayo namakhemikhali, okwenza ifaneleke ezinhlobonhlobo zezicelo zezimboni.

Enye yezinzuzo eziyinhloko ze-reaction-sintered silicon carbide ceramics ubulukhuni bayo obungavamile kanye nokumelana nokugqoka. Lezi zakhiwo zizenza zilungele ukusetshenziswa ezindaweni ezinzima ezifana nezimayini, lapho okokusebenza kungaphansi kokuguga nokuguguleka. Izingxenye ze-RS-SiC ezifana namalayini angagugi, ama-nozzle nama-impeller asetshenziswa kabanzi emisebenzini yezimayini ukuze kuthuthukiswe ukuqina nokusebenza kwezisetshenziswa ezivezwe ezintweni nezimo ezinokhahlo. Ukumelana okuphakeme kokugqokwa kwe-RS-SiC ceramics kusiza ukunciphisa isikhathi sokuphumula kanye nezindleko zokuyilungisa, okwenza kube ukukhetha kokuqala kwezicelo zezimayini.

Ngaphezu kwezimayini, i-react-sintered silicon carbide ceramics isetshenziswa kabanzi embonini yamandla. I-RS-SiC's conductivity enhle kakhulu ye-thermal kanye nokuzinza kwezinga lokushisa eliphezulu kuyenza ibe into efanelekile yezingxenye zezinhlelo zokuphehla amandla nokusabalalisa. Lawa ma-ceramics asetshenziswa ezinhlelweni ezifana nezinto zokushisisa izinga lokushisa eliphezulu, amashubhu okuvikela i-thermocouple, nezingxenye zokuvikela ukufakwa kukagesi. I-RS-SiC iyakwazi ukumelana namazinga okushisa adlulele kanye nokushaqeka okushisayo, okwenza kube ukukhetha okuthembekile kwezingxenye ezibalulekile ezitshalweni zamandla nezinhlelo zikagesi.

Ngaphezu kwalokho, ukungena kwamakhemikhali kwe-reaction-sintered silicon carbide ceramics kuyenza ifanelekele ukusetshenziswa ezindaweni ezigqwalile. Ziyakwazi ukumelana nokuhlaselwa kwamakhemikhali kanye ne-oxidation futhi zisetshenziswa ezimbonini zokukhiqiza amakhemikhali, i-metallurgical kanye ne-semiconductor. Izingxenye ze-RS-SiC zisetshenziswa ezinqubweni ezibandakanya amakhemikhali abolayo, izinsimbi ezincibilikisiwe namagesi ashisa kakhulu lapho izinto ezivamile zingehlisa noma zehluleke. Ukumelana nokugqwala nokuzinza kwezitsha zobumba ze-RS-SiC kusiza ukukhulisa ubude bemishini nokuthembeka kulezi zindawo eziyinselele.

Njengomkhiqizi omkhulu kunawo wonke wezingxenye ezenziwe ngokwezifiso ze-silicon carbide Ceramic ezimise okukhethekile e-China, inkampani yethu izibophezele ekuhlinzekeni izingxenye ze-RS-SiC zekhwalithi ephezulu ezenziwe ngomthungo ukuze zihlangabezane nezidingo ezithile zezimboni ezahlukene. Sinikezela ngezingxenye ze-ceramic ezenziwe ngokunemba, okuhlanganisa amajiyometri ayinkimbinkimbi nemiklamo eyinkimbinkimbi, ukuze kuhlangatshezwane nezidingo ezihlukile zamakhasimende ethu. Ubuchwepheshe bethu kubuchwepheshe be-sintering obusebenzayo busivumela ukuthi sikhiqize izimo eziyinkimbinkimbi ezinokubekezelelana okuqinile, siqinisekise ukusebenza kahle nempilo yesevisi yezingxenye ze-ceramic ezinhlelweni ezihlukahlukene.

Ukuguquguquka kwezinto zobumba ze-silicon carbide ceramics ezisabela ngezindlela ezihlukahlukene kudlulela ngale kwezakhiwo zayo zemishini namakhemikhali. Lawa ma-ceramics abuye abonise ukufakwa kukagesi okuhle kakhulu, ukunwebeka okushisayo okuphansi kanye nokuqina okuphezulu, okuwenza afanelekele ukusetshenziswa ezinhlelweni zobunjiniyela ezithuthukile. Ikhono lazo lokulondoloza ukuqina kobukhulu emazingeni okushisa aphezulu kanye nezindawo ezinokhahlo lithuthukisa nakakhulu ukukhanga kwazo endaweni yezindiza, ezimbonini zezimoto nezokuvikela. Izingxenye ze-RS-SiC zisetshenziswa ezinhlelweni zokuqhuma kwe-aerospace, amasistimu wokubhuleka ezimoto kanye nezicelo zezikhali, lapho izakhiwo zazo eziphakeme zisiza ukuthuthukisa ukusebenza nokuthembeka.

Kafushane, izinto zobumba ze-silicon carbide ceramics ezisabelayo zinikeza inhlanganisela ephoqelelayo yezakhiwo ezizenza zibaluleke kakhulu kuhlelo olubanzi lwezinhlelo zokusebenza zezimboni. Ukuqina kwayo okungavamile, ukumelana nokugqoka, ukuguquguquka okushisayo kanye nokungangeni kwamakhemikhali kuyenza ibe yisinqumo sokuqala sezindawo ezidinga kakhulu ezimayini, ukukhiqiza ugesi, ukucubungula amakhemikhali nezinye izimboni. Njengomkhiqizi ohamba phambili wezingxenye ezenziwe ngokwezifiso ze-silicon carbide ceramic ezimise okukhethekile, inkampani yethu izibophezele ekunikezeni izixazululo ezintsha ezithuthukisa izinzuzo eziyingqayizivele ze-RS-SiC ukuhlangabezana nezidingo ezihlala zishintsha zamakhasimende ethu. Sigxila kwikhwalithi, ukunemba kanye nokwenza ngokwezifiso, futhi sizibophezele ekuthuthukiseni ukusetshenziswa kwe-react-sintered silicon carbide ceramics emikhakheni ehlukahlukene, okunikela ekuthuthukiseni ukusebenza, ukusebenza kahle nokuthembeka kwezinqubo ezibalulekile zezimboni.
