ZTA (Zirconia Toughened Alumina) ceramic liningchinhu cheinjiniya chine simba guru chakagadzirwa nekuisa chikamu chezirconia (ZrO₂) muchikamu chealumina (Al₂O₃). Chimiro ichi chakabatana chinosanganisa kuomarara kwakanyanya kwealumina nehunhu hwekuchinja kwechikamu chezirconia, nokudaro zvichiwedzera zvakanyanya kuomarara kwechinhu uye kuramba kukanganiswa nemagetsi. Chimiro chayo chakajairika chakafanana uye chakakora, chine huwandu hwakawanda hunowanzo ≥3.95 g/cm³ uye kuomarara kweRockwell (HRA) kunogona kudarika 85. Chinhu ichi chinogadzirwa kuburikidza nekugadzirisa hupfu hwakacheneswa, kudzvanya kweisostatic, uye kupisa kwakanyanya, zvichiita kuti pave nekugadzikana kwakanaka kwemuviri uye kwemagetsi.
Zvakanakira zvikuru zvejira iri zviri mukudzivirira kwayo kupfeka nekuora. Munzvimbo dzinoshanda dzemaindasitiri, mwero wekupfekwa kweZTA ceramic unogona kuva wakaderera ne30%-50% pane wesimbi dzemhando yepamusoro dzealumina. Kudzivirira kwayo kupfeka kunobatsira kubva mukuomarara kwakanyanya kunodzivirira kucheka kunorwadza uye nzira yekunyungudutsa simba re microcracks inogadzirwa nekuchinja kwe zirconia phase. Panguva imwe chete, ine makemikari asina simba zvakanyanya, inodzivirira kukurwa kubva muacid nealkali media yakawanda (kunze kwe hydrofluoric acid uye concentrated hot strong alkalis). Inoramba ichishanda zvakanaka kana ikasangana nekupisa kwakanyanya kwenguva refu (tembiricha yepamusoro yekushandira kusvika 850°C) uye mamiriro ekushanda akaomarara, ine hupenyu hwebasa hunopfuura zvakanyanya hwezvinhu zvechinyakare zvekudzivirira simbi.
ZTA ceramic lining inoshandiswa zvakanyanya mumaindasitiri ane kusakara kwakanyanya, kusanganisira kugadzira magetsi ekupisa, kugadzira migodhi, kugadzira simende, kunyungudutsa simbi, uye masisitimu ekubata zvinhu. Nzvimbo dzakakosha dzekushandisa dzinosanganisira madutu anoparadzanisa, magokora emapaipi, mafeni anopinza, machute, mahopper, uye michina yakasiyana-siyana yekuisa hupfu. Nzira dzayo dzekuisa dzakasiyana-siyana, dzakadai sekubatanidza, kubhota, kana kupinza mumodular, zvichidzivirira zvinobudirira substrates dzemidziyo. Izvi zvinoderedza zvakanyanya kuwanda kwemitengo yekugadzirisa uye yekugadzira inokonzerwa nekusakara, zvichiwedzera kushanda zvakanaka kwesystem uye kuchengetedzeka.
Muchidimbu, ZTA alumina ceramic lining yave chinhu chakakosha chehunyanzvi mukuchengetedza kupfeka kwemaindasitiri, nekuda kwekugadzirwa kwayo kwakagadziridzwa nesainzi uye kushanda kwayo kwakanaka kunosimbiswa. Inopa vimbiso yakavimbika yekushanda kwakasimba kwenguva refu kwemidziyo munzvimbo dzakaoma, ichipa mabhenefiti akakosha ehupfumi uye kukosha kwekushandisa. Kutsvagurudza kuri kuenderera mberi muzvinhu nekugadzirisa kuchawedzera miganhu yayo yekushanda uye huwandu hwemashandisirwo.
