Mukugadzirwa kwesimende, michina yakaita semapaipi anofambisa zvinhu, dzimba dzekuparadzanisa, madutu, uye machute zvinogara kwenguva refu zvichikanganiswa nekukurumidza uye zvichitsvedza, zvichikonzera kurasikirwa nekukurumidza kwesimbi uye kuwedzera kwemari yekugadzirisa nguva yekushanda. Kushandiswa kwe alumina ceramic lining isingaparare kunotambanudza hupenyu hwebasa zvakanyanya. Iyi lining inoumbwa kuburikidza nekupisa kwakanyanya, ine alumina iri pasi pe92%, huwandu hwakawanda hwe ≥3.60 g/cm³, Rockwell hardness (HRA) pamusoro pe 85, uye vhoriyamu yekupfekwa iri pasi pe 0.1 cm³ (yakaedzwa zvichienderana ne GB/T 8489-2006).
Zvichienzaniswa nemaplate esimbi akajairika anodzivirira kupera (semuenzaniso, NM400), alumina ceramic lining ine simba rekudzivirira kupera rakapetwa ka5-8, pamwe chete ne low surface friction coefficient (inenge 0.2-0.3 mumamiriro ekunze akaoma), zvichideredza njodzi yekunamatira kwezvinhu uye kuvharika. Mataira eceramic anosungirirwa kumadziro emukati memidziyo achishandisa epoxy resin kana inorganic adhesive, ane tembiricha yekushanda kubva -50°C kusvika 300°C uye kushivirira kwenguva pfupi kusvika 500°C. Pasi pemamiriro enguva dzose emiti yesimende, ceramic lining inowedzera hupenyu hwebasa rechute kubva pamwedzi mitanhatu kusvika kumwedzi inopfuura makumi matatu nematanhatu.

Inowanikwa mumaplate eceramic kana matiles emosaic, lining yacho inochinjika kune michina ine makombama akasiyana uye maumbirwo echimiro.
