Inqubo kanye nezinzuzo zobuchwepheshe bokubumba umjovo we-ceramic

I-Ceramic isiphenduke into ekhethwayo ekugqokeni okuhlakaniphile ngenxa yobufakazi bayo bokuklwebheka, obulungele isikhumba, obungaguquki, umbala we-jade kanye nezindleko eziphansi. Futhi ukubumba komjovo we-ceramic kungenye yezinqubo eziyinhloko zokubumba izingxenye zokubukeka ze-ceramic ezigqokekayo.

Inqubo yokubumba umjovo we-Ceramic

Ukubunjwa komjovo we-Ceramiciyindlela yokubumba yepulasitiki eseduze nenetha eyakhiwe ngesisekelo sobuchwepheshe bokubumba umjovo we-polymer. Inqubo eyisisekelo yokubunjwa komjovo we-ceramic okugqokekayo okugqokekayo ikakhulukazi ihlanganisa izigaba ezine: ukulungiswa kokuphakela, ukubumba umjovo, ukwehlisa amafutha kanye nokucwilisa.

1. Ukulungiswa kokuphakelayo I-yttrium stabilized zirconia powder kanye ne-surfactant ikalwa ngokulingana, i-ethanol iyengezwa, bese ihlanganiswa nokugaya ibhola, yomiswe futhi ihlolwe ukuze kutholwe udaka, bese ixutshwa ne-binder, ixutshwe futhi ifakwe granulated ukuze kutholwe ukudla komjovo.

Ukhiye wokulungiselela ukudla:

Khetha i-binder efanele, i-binder kanye ne-ceramic powder ukuhambisana nokuhlakazeka kahle kwe-shear, susa i-agglomeration;

Okuqukethwe kwe-binder okufanele, ukuze okuphakelayo kube noketshezi oluhle;

Ukwenyuka kokulayishwa kwempushana ye-ceramic (okuqukethwe okuqinile) kanye nokuwohloka kwe-dimensional okuncishisiwe.

I-2, ukubumba komjovo kuzoba okuphakelayo kokubumba okufakwe emshinini wokubumba umjovo, kushiswe kuncibilike i-viscous, ekushiseni okuthile nokucindezela umjovo wesivinini esikhulu esibunjeni sensimbi, ukupholisa ngemuva kokukhumula ukuze uthole umzimba we-ceramic billet. Ukhiye wokubumba umjovo:

Ukwakhiwa kwesikhunta okunengqondo nokucubungula (isango, umgijimi, ukunemba, impahla, njll.)

Ukusetha kanye nokwenza kahle kwemingcele yomjovo (izinga lokushisa, ingcindezi, izinga lokushisa lesikhunta)

Ukukhipha amandla nokucindezeleka komzimba ngesikhathi sokugcwalisa isikhunta

3, ukwehlisa amafutha kuyinqubo yokukhipha ingxenye ye-binder kumjovo wokubumba i-ceramic billet ngezindlela ezibonakalayo noma zamakhemikhali. Ngenxa yesistimu ye-binder ehlukene, inqubo yokwehlisa ihlukile, izindlela zokususa umjovo zokubumba ze-ceramic zifaka: ukukhishwa kwe-thermal, ukukhishwa kwe-solvent, ukukhishwa kwe-catalytic, ukukhetha ubuchwepheshe obusebenzayo nobuphephile bokwehlisa amafutha, thola kungenalutho.

4. Sintering

I-ceramic blank yashiswa ekushiseni okuphezulu kwe-1300 ° C ~ 1800 ° C. I-Sintering iyinqubo yokwenza i-ceramic billet. Ingxenye enkulu yokusebenza kwemikhiqizo ye-ceramic inqunywa nge-sintering. I-Zirconia Ceramics idinga ukuminyana okuphezulu kanye ne-uniform sintering, hhayi kuphela inqubo yokunciphisa ibaluleke kakhulu, kodwa futhi ithinteka yi-powder, izithasiselo, izinga lokushisa le-sintering nesikhathi, ingcindezi kanye nomkhathi we-sintering nezinye izici.

 Izinzuzo zokubumba umjovo we-ceramic

Izingxenye zokubukeka ze-ceramic ezigqokekayo ezigqokekayo zifaka ikesi lewashi le-ceramic, i-ceramic bezel, ukudayela kwe-ceramic, ikhava engezansi ye-ceramic, umqhele we-ceramic, uchungechunge lwewashi le-ceramic neminye imikhiqizo, usayizi omncane, izidingo zokunemba okuphezulu.

Izinzuzo zokusebenzisa ukubumba komjovo we-ceramic kokugqokekayo okuhlakaniphileizingxenye zokubukeka ze-ceramicyilezi:

Kungaba seduze nenetha lokubunjwa kwejiyomethri eyinkimbinkimbi futhi ibe nezidingo ezikhethekile zezingxenye ezincane ze-ceramic, imikhiqizo yokubumba ngokunemba okuphezulu, iyunifomu ye-green density, amandla aphezulu, ukusebenza komzimba we-sintered kanye nokuvumelana kwekhwalithi yomkhiqizo kuhle, ukuze imikhiqizo ye-ceramic ye-sintered ngaphandle komshini noma ukucutshungulwa okuncane, ukuze kuncishiswe izindleko zokucubungula ze-ceramic ezibizayo;

Inqubo yokubumba inezinga eliphezulu lemishini kanye ne-automation, umjikelezo wokubumba umfushane, ukuphathwa nokulawulwa kwenqubo yokukhiqiza nakho kulula kakhulu, kulula ukufeza ukukhiqizwa kobuningi, ukukhiqizwa okukhulu;

Imikhiqizo ye-ceramic ebunjiwe inokunemba okuphezulu kakhulu kwe-dimensional kanye nokuqedwa kwendawo, ukuqedwa okungaphezulu kungafinyelela ku-5um. Ngakho-ke,Ubuchwepheshe bokubumba umjovo we-ceramic we-CIMisibe ngenye yezindlela zokwenza ubuchwepheshe obukhona bokubumba i-ceramic.
