Kubuchwepheshe banamuhla obuthuthuka ngokushesha, ukuvela okuqhubekayo kwezinto ezintsha kulethe izinguquko ezinkulu ezimbonini ezahlukene.Izitsha zobumba zezimboni ze-silicon carbide, njengezinto ezisebenza kahle kakhulu, ziyavela kancane kancane embonini yesimanje. Ngokusebenza kwazo okuhle kakhulu kanye nobubanzi bezicelo, sezibe yimbangela ebalulekile yentuthuko ezimbonini ezahlukahlukene.
1. Kuyini i-silicon carbide ceramic yezimboni?
Ama-ceramic ezimboni e-silicon carbide, ngamagama alula, ayizinto zobumba ezakhiwe kakhulu nge-silicon carbide (SiC). I-Silicon carbide ngokwayo iyinhlanganisela eyakhiwa ukusabela kwe-silicon ne-carbon emazingeni okushisa aphezulu, futhi isakhiwo sayo se-athomu esiyingqayizivele sinikeza le nto izakhiwo eziningi ezinhle kakhulu.
Ngombono omncane kakhulu, isakhiwo sekristalu se-silicon carbide sincane, futhi izibopho zamakhemikhali phakathi kwama-athomu ziqinile, okwenza i-silicon carbide ceramics ibe nokuzinza nokuqina okuhle kakhulu. Uma kuqhathaniswa nezinto zensimbi zendabuko, i-silicon carbide ceramics yezimboni ayenziwa ngama-athomu ensimbi ahlanganiswe yizibopho zensimbi; Ngokungafani nezinto ezivamile ze-polymer polymer, ayihlanganiswa ngamaketanga aphindaphindwayo e-organic molecular. Luhlobo olusha lwezinto ezingezona ezensimbi ezingaphili ezakhiwe ngokucwilisa i-silicon carbide powder ngaphansi kwezimo zokushisa okuphezulu kanye nokucindezela okuphezulu ngenqubo ekhethekile yokulungiselela i-ceramic.
2, Ukwembula Ukusebenza Okuhle Kakhulu

3. Ukuqina okuhle kwamakhemikhali
Kungakhathaliseki ukuthi ubhekene namakhemikhali agqwalisayo njenge-asidi eqinile noma izisekelo, i-silicon carbide industrial ceramics ingakwazi ukuyiphatha ngokuthula. Ekukhiqizweni kwamakhemikhali, kuvame ukudingeka ukuphatha izinto zokusetshenziswa zamakhemikhali ezigqwalisayo kakhulu, futhi izitsha namapayipi asetshenziselwa ukugcina nokuthutha lezi zinto zokusetshenziswa zidinga ukumelana nokugqwala okuphezulu kakhulu kwezinto zokusetshenziswa. I-Silicon carbide industrial ceramics, ngokuqina kwayo okuhle kwamakhemikhali, isibe yinto efanelekile yokwenza lezi zitsha namapayipi, igwema ngempumelelo izingozi zokuphepha njengokuvuza okubangelwa ukugqwala.
4. Ukushisa okuhle kakhulu
Izitsha zobumba ze-silicon carbide zezimboni zinokuqhuba kahle kakhulu kokushisa futhi zingahambisa ukushisa ngokushesha. Lokhu kusebenza kunezinhlelo ezibalulekile ezimweni ezidinga ukushabalaliswa kokushisa ngesikhathi esifanele, njengeminye imishini yokusebenza enokushisa okuphezulu, lapho ukuqongelela kokushisa ngokweqile kungathinta ukusebenza okuvamile. Izingxenye zokushabalaliswa kokushisa ezenziwe ngezitsha zobumba ze-silicon carbide zezimboni zingashabalalisa ukushisa ngokushesha, ziqinisekise ukusebenza okuzinzile kwemishini.
3, Amasimu asetshenziswa kabanzi
1. Ukukhiqiza ngomshini
Embonini yokukhiqiza imishini, izitsha zobumba zezimboni ze-silicon carbide zisetshenziselwa ukukhiqiza izingxenye ezahlukahlukene ezingagugi njengezitsha zobumba, izindandatho zokuvala, amathuluzi okusika, njll. Uma kuqhathaniswa nama-bearings ensimbi endabuko, ama-bearings e-silicon carbide ceramic anobulukhuni obukhulu kanye nokumelana nokuguguleka, futhi angasebenza ngokuzinzile ngaphansi kwezimo ezinzima njengesivinini esikhulu kanye nokushisa okuphezulu, okuthuthukisa kakhulu ukusebenza kanye nokuthembeka kwemishini yobumba.
2. Imboni yezinsimbi zemayini
Isimo emkhakheni wezokumbiwa kwensimbi sivame ukuba nzima, futhi imishini ibhekene nokuhlolwa okuningi okufana nokuguguleka, izinga lokushisa eliphezulu, kanye nokugqwala.
