Njengohlobo olusha lwezinto ezingezona ezensimbi, ingcindezi yasemkhathini ye-silicon carbide ceramic imikhiqizo isetshenziswe kabanzi kuhhavini, ekuqothulweni nasekuvikelweni kwemvelo, imboni yamakhemikhali, insimbi, i-aerospace kanye neminye imikhakha. Kodwa-ke, ukusetshenziswa kwemikhiqizo ye-ceramic ye-sintered silicon carbide ceramic kusesesigabeni esijwayelekile, futhi kunenombolo enkulu yezinkambu zohlelo lokusebenza ezingazange zibe nentuthuko enkulu, futhi usayizi wemakethe mkhulu. Njengomkhiqizi we-atmospheric pressure sintered silicon carbide ceramics, kufanele siqhubeke nokuqinisa ukuthuthukiswa kwemakethe, sithuthukise ngokunengqondo umthamo wokukhiqiza, futhi sibe sesimweni esiphakeme emkhakheni omusha wokusetshenziswa kwezitsha ze-silicon carbide ceramics.
Ingxenye engenhla yemboni ikakhulukazi ingcindezi yasemkhathini i-silicon carbide smelting kanye nokukhiqizwa kwempushana. Ingxenye engezansi yemboni ihlanganisa izinhlobonhlobo eziningi, okuhlanganisa cishe zonke izimboni ezidinga izinga lokushisa eliphezulu, izinto ezigugayo nezimelana nokugqwala.
(1) Imboni ekhuphuka nomfula
I-silicon carbide powder kanye ne-silicon powder yensimbi yizinto ezingavuthiwe ezidingekayo embonini. Ukukhiqizwa kwe-silicon carbide yaseChina kwaqala ngawo-1970. Ngemuva kweminyaka engaphezu kwengu-40 yentuthuko, imboni isihambe ibanga elide. Ubuchwepheshe bokuncibilika, imishini yokukhiqiza kanye nezinkomba zokusetshenziswa kwamandla sekufinyelele ezingeni elihle. Cishe i-90% ye-silicon carbide yomhlaba ikhiqizwa eChina. Eminyakeni yamuva, intengo ye-silicon carbide powder ayizange ishintshe kakhulu; I-Metal silicon powder ikhiqizwa ikakhulukazi eYunnan, eGuizhou, eSichuan nakwezinye izifunda eziseningizimu-ntshonalanga. Lapho amanzi nogesi kuchichima ehlobo, inani lentengo ye-silicon powder lishibhile, kanti ebusika, intengo iphakeme kancane futhi iyaguquguquka, kodwa ngokuvamile izinzile. Ukushintsha kwentengo yezinto zokusetshenziswa embonini ekhuphuka nomfula kunomthelela othile kuzinqubomgomo zentengo yomkhiqizo kanye namazinga ezindleko ezinkampani embonini.
(2) imboni esezansi nomfula
Indawo engezansi yemboni imboni yesicelo somkhiqizo we-silicon carbide ceramic. Imikhiqizo ye-silicon carbide ceramic ayigcini nje ngokuhlukahluka, kodwa futhi nokusebenza okuhle kakhulu. Isetshenziswa kabanzi ekwakheni, i-sanitary ceramics, i-ceramics yansuku zonke, izinto kazibuthe, ingilazi-ceramics, izithando zezimboni, izimoto, amaphampu, ama-boilers, iziteshi zikagesi, ukuvikelwa kwemvelo, ukwenza iphepha, i-petroleum, i-metallurgy, imboni yamakhemikhali, imishini, i-aerospace kanye neminye imikhakha. Ngokusebenza okuphezulu kwemikhiqizo ye-silicon carbide ceramic kuye kwaqashelwa yizimboni eziningi, uhla lokusetshenziswa kwemikhiqizo ye-silicon carbide ceramic luzoba banzi kakhulu. Intuthuko enempilo, eqhubekayo futhi esheshayo yemboni engezansi izohlinzeka indawo yemakethe ebanzi yemboni futhi ikhuthaze ukuthuthukiswa okuhlelekile kwayo yonke imboni.
Ngokusetshenziswa okubanzi kwemikhiqizo yobumba ye-sintered silicon carbide ceramic, isidingo semakethe siyanda, siheha ingxenye enkulu yenhloko-dolobha emkhakheni wokukhiqiza i-silicon carbide ceramic. Ngakolunye uhlangothi, izinga lemboni ye-silicon carbide liyaqhubeka nokukhula, futhi ukukhiqizwa kwesifunda sokuqala kancane kancane kusatshalaliswa kuzo zonke izingxenye zezwe. Esikhathini esifushane seminyaka eyishumi, imboni ye-silicon carbide ithuthuke ngokushesha. Ngakolunye uhlangothi, ngenkathi izinga lemboni liqhubeka nokukhula, liphinde libhekane nesimo sokuncintisana okunonya. Ngenxa yomkhawulo ophansi wokungena embonini, inani lamabhizinisi okukhiqiza likhulu, ubukhulu bamabhizinisi buhlukile, futhi ikhwalithi yomkhiqizo ayilingani.
Amanye amabhizinisi amakhulu agxila ekuthuthukisweni kobuchwepheshe kanye nocwaningo nokuthuthukiswa kwemikhiqizo emisha; Isilinganiso siyaqhubeka nokukhula, futhi ukubonakala nomthelela wenkampani kuyanda usuku nosuku. Ngesikhathi esifanayo, abakhiqizi abaningi abancane bangathembela kuphela kumasu amanani aphansi ukuze babambe ama-oda, okuholela ekuqhudelaneni okunonya embonini. Ukuncintisana kule mboni kushubile, kanti imboni izophinde ikhombise ukuthambekela kwe-polarization.
