Iityhubhu ze-liner ze-alumina ceramic ezingagugiyozizinto ezibalulekileyo ezikhuselayo ezisetyenziswa kakhulu kwiinkqubo zemibhobho yemizi-mveliso ezichaphazeleka kakhulu kukukrala okukhulu. Ulwakhiwo lwazo oluphambili yi-alpha-alumina (Al₂O₃), kunye nomxholo oqhelekileyo ukusuka kwi-92% ukuya kwi-99.5%. Ezi zinto zenziwe ngenkqubo yokusila ngobushushu obuphezulu, nto leyo ebangela ubunzima obungaqhelekanga, kunye nobunzima beRockwell (HRA) obuyi-≥85 kunye nomgangatho wobunzima beMohs obuyi-9, obulandelayo emva kwedayimani. Ezi tyhubhu ze-liner zibotshelelwe ngokukhuselekileyo okanye zifakwe ngoomatshini eludongeni lwangaphakathi lwemibhobho yesinyithi, zenza umqobo oqinileyo wokukhusela ohlukanisa ngokufanelekileyo i-medium egelezayo ekukhuculweni ngokuthe ngqo nasekugugeni komzimba wemibhobho yesinyithi.
Ukusebenza kwazo okuphezulu kuvela kwiimpawu ze-alumina ceramics. Ukongeza ekubeni lukhuni kakhulu, uxinano lwazo luqhele ukuba ngaphezulu kwe-3.6 g/cm³, kwaye amandla okucinezela angaphezulu kwe-850 MPa. Ukumelana nokuguguleka kwezi ceramic liners kumalunga nama-266 entsimbi ye-manganese kunye nama-171.5 ephindwe kwi-high-chromium cast iron, nto leyo eyandisa ubomi benkonzo yezixhobo ngamaxesha ama-5 ukuya kwali-10 phantsi kweemeko zokusebenza ezifanayo. Umphezulu wazo ogudileyo kunye ne-coefficient ephantsi yokungqubana kunciphisa ngempumelelo ukumelana nokuhambisa. Zikwanokumelana nokugqwala okuhle kakhulu, ukumelana ne-chemical media ezininzi ngaphandle kwe-hydrofluoric acid kunye ne-alkalis ezixineneyo ezishushu.
Le mveliso isetyenziswa kakhulu kumacandelo emizi-mveliso aneemfuno ezingqongqo zokumelana nokuguguleka. Ukusetyenziswa okuqhelekileyo kuquka ukuhambisa amalahle, ukondla amafutha acoliweyo, kunye neenkqubo zokususa uthuthu kwizityalo zamandla obushushu; imibhobho yokuthutha umgubo wamalahle kunye ne-ore ecoliweyo kwimizi-mveliso yentsimbi; imigca yokudlulisa umgubo wengqolowa, i-clinker, kunye ne-coal powder kwizityalo zesamente; kunye neenkqubo zokuthutha uthuli oluxutyiweyo kunye nolwelo oluqinileyo kwimisebenzi yemigodi. Ikwasetyenziswa kakhulu kwimibhobho yokuhambisa umoya kunye ne-hydraulic kwimizi-mveliso yesinyithi, yeekhemikhali, kunye neminye, ijongana ngempumelelo nemiba yokuguga ngokukhawuleza kwemibhobho, ukugqobhoka, kunye nokuvuza okubangelwa kukukhuhla izinto ixesha elide.
Ngamafutshane, iityhubhu ze-alumina ceramic liner ezingagugiyo zibonelela ngokhuseleko lwexesha elide kwiipayipi zokuhambisa izimboni ngenxa yobunzima bazo obuphezulu kakhulu, ukuguguleka okugqwesileyo, kunye nokumelana nokugqwala. Zinciphisa kakhulu ukuvaleka kweendleko zokugcinwa kunye nokutshintshwa okubangelwa kukuguguleka kwepayipi, nto leyo ephucula ukusebenza kakuhle okuqhubekayo kunye nokhuseleko lweenkqubo zemveliso. Zimela isisombululo sokukhusela esiqinisekisiweyo nesingabizi kakhulu.
