I-Alumina ceramics, i-silicon carbide ceramics kanye ne-zirconia ceramics

I-Alumina ceramic ilula ngezinto zokwakha, ivuthiwe kwezobuchwepheshe bokukhiqiza, ishibhile ngezindleko, inhle kakhulu ebulukhunini nasekugugeni. Isetshenziswa kakhulu kumapayipi e-ceramic angagugi, ama-valve angagugi njengezinto zokubopha, futhi ingashintshwa ngama-studs noma inamathiselwe odongeni lwangaphakathi lwemishini yokuhlukanisa efana ne-industrial vertical mill, i-powder concentrator kanye ne-cyclone, enganikeza ukumelana kokugugika okuphindwe kayishumi kobuso bemishini. Ezintweni ezingagugi, isabelo semakethe sezinto ze-alumina singafinyelela cishe ku-60% ~ 70%.

Isici esibaluleke kakhulu sezinto ze-ceramic ze-SiC ukumelana okuhle nokushaqeka kokushisa. Ngaphansi kwezimo zokushisa okuphezulu, izinto zinezakhiwo eziqinile zemishini futhi zingasetshenziswa ngokuzinzile ku-1800 ℃ isikhathi eside. Isici sesibili ukuthi izinto ze-silicon carbide zingasetshenziswa ukwakha imikhiqizo emikhulu enokuguquguquka okuncane. Isetshenziswa kakhulu embonini yesamente elenga ngaphambi kokushisa, i-nozzle ye-ceramic engagugiyo ekushiseni okuphezulu, ipayipi eliwa ngamalahle kanye nepayipi lokudlulisa lokushisa eliphezulu lemboni yamandla okushisa. Isibonelo, ama-nozzle ezitshalweni zamandla okushisa enziwe nge-silicon carbide, futhi imikhiqizo inezimpawu zokumelana nokushisa okuphezulu kanye nokumelana nokuguguleka. Izindlela zokusinta ze-silicon carbide ceramics zifaka phakathi ukusinta kokusabela kanye nokusinta okungenangcindezi. Izindleko zokusinta kokusabela ziphansi, imikhiqizo ilukhuni, kanti ubuningi bemikhiqizo yokusinta ye-vacuum engenangcindezi buphakeme kakhulu. Ubulukhuni bemikhiqizo bufana nobemikhiqizo ye-alumina, kodwa intengo yayo iphakeme kakhulu.

Ukumelana nokugoba kwezinto zobumba ze-zirconia kungcono kunokwezinto ezibuthakathaka. Intengo yamanje yemakethe ye-zirconia powder ibiza kakhulu, esetshenziswa kakhulu emikhakheni ephezulu, njengezinto zamazinyo, amathambo okwenziwa, amadivayisi ezokwelapha, njll.
