Kubuchwepheshe banamuhla obuthuthukayo, ukuvela okuqhubekayo kwezinto ezintsha kulethe izinguquko eziguquguqukayo ezimbonini ezihlukahlukene.I-Silicon carbide ceramics yezimboni, njengezinto ezisebenza kahle kakhulu, kancane kancane zivela embonini yesimanje. Ngokusebenza kwabo okuhle kakhulu kanye nohlu olubanzi lwezinhlelo zokusebenza, sebephenduke amandla ayinhloko aqhuba inqubekelaphambili ezimbonini ezahlukahlukene.
1. Yini i-silicon carbide industrial ceramic?
I-silicon carbide izimboni ze-ceramics, ngamagama alula, ziyizinto zobumba ezakhiwe ngokuyinhloko nge-silicon carbide (SiC). I-silicon carbide ngokwayo iyinhlanganisela eyakhiwe ukusabela kwe-silicon nekhabhoni emazingeni okushisa aphezulu, futhi ukwakheka kwayo okuhlukile kwe-athomu kunikeza impahla ngezinto eziningi ezinhle kakhulu.
Ngokombono we-microscopic, ukwakheka kwekristalu ye-silicon carbide kuhlangene, futhi izibopho zamakhemikhali phakathi kwama-athomu ziqinile, okwenza i-silicon carbide ceramics ibe nokuzinza nokuqina okuhle kakhulu. Uma kuqhathaniswa nezinto zensimbi zendabuko, izinto zobumba ze-silicon carbide zezimboni azikhiwa ama-athomu ensimbi aboshwe ngamabhondi ensimbi; Ngokungafani nezinto ezijwayelekile ze-polymer ephilayo, ayihlanganiswa ngamaketanga aphindaphindwayo we-organic molecule. Iwuhlobo olusha lwezinto ezingezona ezensimbi ezenziwe nge-sintering silicon carbide powder ngaphansi kwezinga lokushisa eliphezulu nezimo zokucindezela okukhulu ngenqubo ekhethekile yokulungiselela i-ceramic.
2, Kwembula Ukusebenza Okuvelele

Ubulukhuni bezimboni ze-silicon carbide ceramics buphezulu kakhulu, okwesibili kuphela kwedayimane ngokwemvelo. Lesi sici senza kube kuhle kakhulu mayelana nokumelana nokugqoka. Cabanga nje emkhakheni wokucutshungulwa kwemishini, amathuluzi okusika adinga ukuhlangana njalo nezinto ezahlukahlukene zensimbi zokusika. Uma into yamathuluzi ingamelani nokuguga ngokwanele, izoguga ngokushesha futhi ibe buthuntu, ithinte ukunemba komshini nokusebenza kahle. Amathuluzi okusika enziwe nge-silicon carbide izimboni ze-ceramics, ngobulukhuni bawo obuphezulu kakhulu, angagcina ubukhali isikhathi eside, athuthukise kakhulu ukusebenza kahle kokucubungula nokunciphisa izindleko zokukhiqiza.
2. Ukumelana nokushisa okuphezulu, okuzinzile futhi okuthembekile
I-silicon carbide ceramics yezimboni inokumelana okuhle kakhulu nokushisa okuphezulu. Ezindaweni ezinezinga lokushisa eliphezulu, izinto eziningi ziyathambisa, ziguquguquke, futhi zincibilike, kuyilapho i-silicon carbide ceramics ingagcina izakhiwo ezinzile ngokomzimba namakhemikhali emazingeni okushisa aphezulu. Isibonelo, ezithandweni zokushisa okuphezulu embonini ye-metallurgical, kuyadingeka ukusebenzisa izinto ezingakwazi ukumelana namazinga okushisa aphezulu ukuze wenze ama-linings esithandweni somlilo, ama-crucibles, nezinye izingxenye. Ama-ceramics emboni ye-silicon carbide angenza lo msebenzi, aqinisekise ukusebenza okuvamile kwesithando sokushisa okuphezulu nokwelula impilo yesevisi yemishini.
3. Ukuzinza okuhle kwamakhemikhali
Kungakhathaliseki ukuthi ibhekene namakhemikhali alimazayo njengama-asidi aqinile noma izisekelo, izitsha zobumba zemboni ye-silicon carbide zingabhekana nazo ngokuzolile. Ekukhiqizweni kwamakhemikhali, kuvame ukudingekile ukuphatha izinto zokusetshenziswa zamakhemikhali ezinhlobonhlobo ezigqwala kakhulu, futhi iziqukathi namapayipi asetshenziselwa ukugcina nokuthutha lezi zinto zokusetshenziswa kudinga ukumelana nokugqwala okuphezulu kakhulu kwezinto. Izitsha zobumba zemboni ye-silicon carbide, ngokuzinza kwazo okuhle kwamakhemikhali, seziyinto efanelekile yokwenza lezi ziqukathi namapayipi, zigwema ngokuphumelelayo izingozi zokuphepha ezifana nokuvuza okubangelwa ukugqwala.
4. Excellent conductivity ezishisayo
I-silicon carbide izimboni ze-ceramics zinokusebenza okuhle kakhulu kwe-thermal futhi zingakwazi ukuphatha ukushisa ngokushesha. Lokhu kusebenza kunezinhlelo zokusebenza ezibalulekile ezimweni ezidinga ukuchithwa kokushisa okufika ngesikhathi, okufana nemishini ethile yokusebenza yezinga eliphezulu lokushisa, lapho ukunqwabelana kokushisa okudlulele kungathinta ukusebenza okuvamile. Izingxenye zokukhipha ukushisa ezenziwe nge-silicon carbide ceramics zezimboni zingasusa ngokushesha ukushisa, ziqinisekise ukusebenza okuzinzile kwemishini.
3, Izinkambu ezisebenza kakhulu
1. Ukukhiqizwa kwemishini
Embonini yokukhiqiza imishini, ama-ceramics emboni ye-silicon carbide asetshenziselwa ukukhiqiza izingxenye ezihlukahlukene ezingagugi ezifana nama-bearings, izindandatho zokuvala, amathuluzi okusika, njll. Uma kuqhathaniswa namabheringi ensimbi yendabuko, ama-silicon carbide ceramic bearings anobunzima obuphakeme nokumelana nokugqoka, futhi angasebenza ngokuzinzile ngaphansi kwezimo ezinzima ezifana nesivinini esiphezulu nokushisa okuphezulu, ukuthuthukisa kakhulu ukusebenza nokuthembeka kwemishini.
2. I-metallurgy yezimayini
Imvelo emkhakheni wezokumbiwa phansi ivamise ukuba nokhahlo, futhi okokusebenza kubhekana nezivivinyo eziningi njengokuguga, izinga lokushisa eliphezulu, nokugqwala. Izitsha zobumba zemboni ye-silicon carbide, ezinokumelana nokugqokwa kwazo okuphezulu kakhulu, zingasetshenziswa ukwenza amapuleti omugqa wemishini yokuchoboza yezimayini kanye nezendlalelo ezingagugi zamarola ensimbi. Phakathi nenqubo yokuchotshozwa kwe-ore, amapuleti e-ceramic lining angakwazi ukumelana nomthelela omkhulu kanye nokungqubuzana kwe-ore, enweba umjikelezo wokubuyisela esikhundleni semishini; Enqubweni ye-metallurgical, ebhekene nokuguguleka kwe-high-temperature melt, izingxenye ze-silicon carbide ceramic nazo zingagcina ukuzinza, ziqinisekise inqubekelaphambili eqhubekayo yokukhiqizwa kwe-metallurgical.
3. I-Industrial desulfurization
Enqubweni ye-desulfurization yezimboni, amagesi abolayo kanye noketshezi oluqukethe isulfure kuhilelekile, okudinga ukumelana nokugqwala okuphezulu kakhulu kwemishini. I-silicon carbide ceramics yezimboni isiphenduke into efanelekile yemishini ye-desulfurization ngenxa yokuqina kwayo okuhle kwamakhemikhali. Isibonelo, imibhobho yesifutho, amapayipi nezinye izingxenye embhoshongweni we-desulfurization zenziwe nge-silicon carbide ceramics, engamelana ngokuphumelelayo nokugqwala kwe-ion sulphur, ukunciphisa ukwehluleka kwemishini, ukuqinisekisa ukusebenza kahle kohlelo lwe-desulfurization, nokusiza amabhizinisi ukufeza izindinganiso zemvelo.
I-silicon carbide ceramics yezimboni isiba into ebaluleke kakhulu futhi ebalulekile embonini yesimanje ngenxa yezakhiwo zabo ezihlukile nezinkambu ezibanzi zokufaka isicelo. Ngikholelwa ukuthi esikhathini esizayo esiseduze, izobonisa amandla amakhulu emikhakheni eyengeziwe futhi ibe negalelo elikhulu ekuthuthukisweni komphakathi wesintu.
