Amathayili e-ceramic e-alumina amelana nokugugulekakuyimikhiqizo ye-ceramic esebenzayo eyenziwe nge-aluminium oxide emsulwa kakhulu (Al₂O₃) ngokucindezela kanye nokushisa okuphezulu. Okuqukethwe kwayo kwe-Al₂O₃ kuvame ukuba ngu-92%, 95%, noma 99%, ngobuningi obusukela ku-3.60 g/cm³ kuya ku-3.90 g/cm³ kanye nokumuncwa kwamanzi ngaphansi kuka-0.01%. Izinto ezibonakalayo zibonisa ubulukhuni obuphezulu kanye nokuqina okuhle kwamakhemikhali, okulungele izimo zezimboni ezihilela umthelela, ukungqubuzana okushelelayo, kanye nemidiya ebolile.
Amapharamitha okusebenza ajwayelekile: Ubulukhuni be-Mohs obungu-9, ubulukhuni be-Rockwell HRA 85-90, kanye nokumelana nokuguguleka okuphindwe izikhathi ezingu-20-30 kunokwensimbi yekhabhoni evamile (ukuguguleka kwevolumu ≤0.05 cm³ ngokuhlolwa kwesondo lerabha yesihlabathi esomile se-ASTM G65). Amandla okugobeka afinyelela ku-250-350 MPa, ukuhanjiswa kokushisa cishe ku-25-30 W/(m·K), kanye nokushisa kokusebenza kusuka ku--50 °C kuya ku-1200 °C (kuye ngokuthi ibanga elithile lingakanani). Le datha iqinisekisa ukuthembeka kwesikhathi eside ngaphansi kwezimo zokuguguleka okuphezulu kanye nokushisa okuphezulu.
Lo mkhiqizo usetshenziswa kabanzi ekuvikeleni ukuguguleka kwemishini ebalulekile kuzo zonke izimboni zesimende, insimbi, amandla, izimayini, kanye namalahle, njengezinsimbi zokuhlukanisa, ama-chutes, ama-pipe elbows, ama-cyclone, kanye nama-hopper linings. Izindlela zokufaka zifaka phakathi i-epoxy resin bonding, i-bolting, noma i-welding (kusetshenziswa amathayili e-ceramic abholiwe ngaphambilini ahlanganiswe namapuleti enjoloba/ensimbi). Ubukhulu obujwayelekile busukela ku-5 mm kuya ku-25 mm; osayizi abavamile bamathayili bafaka phakathi u-10 mm × 10 mm, 20 mm × 20 mm, kanye no-50 mm × 50 mm ukuma kwesikwele noma kwe-hexagonal ukuze kube lula ukusika nokubeka endaweni.
Ukusebenzisa amathayili e-alumina ceramic angagugi kwandisa kakhulu impilo yesevisi yemishini futhi kunciphisa isikhathi sokungasebenzi sokulungisa. Idatha yasensimini ikhombisa ukuthi ngaphansi kwezimo ezifanayo zokusebenza, ama-lining e-ceramic ahlala isikhathi eside ngokuphindwe ka-3-8 kunensimbi ye-manganese ephezulu noma amapuleti ensimbi ye-alloy angagugi. Umkhiqizo awunama-magnetic, umelana nokugqwala kwe-acid/alkali (ngaphandle kwe-hydrofluoric acid kanye ne-alkali egxilile eshisayo), futhi awungcolisi izinto. Ukukhetha kufanele kunqume okuqukethwe kwe-Al₂O₃ kanye nobukhulu bethayili ngokusekelwe ekhoneni langempela lomthelela, usayizi wezinhlayiya, kanye nokushisa ukuze kufezwe ibhalansi phakathi kokusebenza kanye nezindleko.
