Machubhu e alumina ceramic liner anodzivirira kupfekachinhu chakakosha chekudzivirira chinoshandiswa zvakanyanya mumaindasitiri emapombi ane makuhwa akanyanya. Muumbirwo wawo mukuru ialpha-alumina (Al₂O₃), ine huwandu hunowanzova pakati pe92% kusvika 99.5%. Chinhu ichi chinogadzirwa kuburikidza nemaitiro ekupisa zvakanyanya, zvichikonzera kuomarara kwakanyanya, neRockwell hardness (HRA) ye≥85 uye Mohs hardness rating ye9, yechipiri chete kune dhaimani. Machubhu aya e liner akabatanidzwa zvakachengeteka kana kuti akaiswa nehunyanzvi pamadziro emukati mepombi dzesimbi, zvichiita chipingamupinyi chakasimba chekudzivirira chinobvisa zvinobudirira nzira inoyerera kubva pakukwesha zvakananga uye kupera pamuviri wepombi yesimbi.
Kushanda kwavo zvakanaka kunobva pahunhu hwezvinhu zve alumina ceramics. Pamusoro pekuoma kwazvo, huwandu hwavo hunowanzova >3.6 g/cm³, nesimba rekudzvanya rinodarika 850 MPa. Kusapera kwemidziyo iyi yeceramic kunopfuura ka266 kupfuura simbi ye manganese uye ka171.5 kupfuura simbi ine chromium yakawanda, zvichiita kuti hupenyu hwemidziyo huwedzere ka5 kusvika ku10 mumamiriro ekushanda akafanana. Pamusoro payo panyoro uye coefficient yakaderera yekukweshana zvinoderedza kudzivirira kwekutakura. Idzo dzinewo kudzivirira ngura kwakanyanya, dzinotsungirira makemikari akawanda kunze kwe hydrofluoric acid uye hot concentrated alkalis.
Chigadzirwa ichi chinonyanya kushandiswa mumaindasitiri ane zvinodiwa zvakasimba zvekuti hachina kupfeka. Zvinowanzo shandiswa zvinosanganisira kuburitsa marasha, kupa mafuta akapwanywa, uye masisitimu ekubvisa madota mumafekitori emagetsi anodziya; mapaipi ekufambisa upfu hwemarasha neore akapwanywa mumafekitori esimbi; mitsetse yekufambisa upfu hwemarara, clinker, uye marasha mumafekitori esimende; uye masisitimu ekufambisa matope netsvina mumabasa ekuchera. Inoshandiswawo zvakanyanya mumapaipi ekufambisa emhepo uye ehydraulic mumafekitori esimbi, makemikari, nemamwe, zvichigadzirisa matambudziko ekukurumidza kupera kwepaipi, kubooka, uye kubuda kwemvura kunokonzerwa nekukweshwa kwezvinhu kwenguva refu.
Muchidimbu, machubhu e alumina ceramic liner asingaparare anopa dziviriro yenguva refu kumapaipi anotakura zvinhu mumaindasitiri kuburikidza nekuoma kwawo kwakanyanya, kupera kwakanyanya, uye kuramba ngura. Anoderedza zvakanyanya kuvharwa kwemari yekugadzirisa nekutsiva kunokonzerwa nekupfekwa kwemapaipi, zvichiwedzera kushanda zvakanaka uye kuchengetedzeka kwemasisitimu ekugadzira. Anomiririra mhinduro yekudzivirira yakayerwa uye inoshanda zvishoma.
