I-ZTA (Zirconia Toughened Alumina) i-ceramic liningsisixhobo sobunjineli esisebenza kakuhle esenziwe ngokungenisa isigaba se-zirconia (ZrO₂) kwi-matrix ye-alumina (Al₂O₃). Esi sakhiwo sidibeneyo sidibanisa ubulukhuni obuphezulu be-alumina kunye neempawu zokuqina zokuguqulwa kwesigaba se-zirconia, ngaloo ndlela siphucula kakhulu ubulukhuni bokwaphuka kwesixhobo kunye nokumelana nempembelelo yoomatshini. Ulwakhiwo lwayo oluqhelekileyo lufana kwaye luxineneyo, kunye noxinano olukhulu ngokubanzi ≥3.95 g/cm³ kunye nobunzima beRockwell (HRA) obunokudlula i-85. Esi sixhobo siveliswa ngokucutshungulwa komgubo ocociweyo, ukucinezelwa kwe-isostatic, kunye nokusila kobushushu obuphezulu, ukuqinisekisa uzinzo oluhle kakhulu lomzimba nolwemishini.
Iingenelo eziphambili zale layini zikwimeko entle kakhulu yokuguguleka nokugqwala. Kwiindawo zokuguguleka ezisebenzayo kwimizi-mveliso, izinga lokuguguleka le-ZTA ceramic linokuba ngaphantsi ngama-30%-50% kunele-ceramics eziqhelekileyo ezine-alumina ephezulu. Ukuguguleka kwayo kuxhamla kwi-hardness ephezulu echasayo ukusika okurhabaxa kunye nendlela yokufunxa amandla e-microcracks eveliswa yi-zirconia phase transformation. Kwangaxeshanye, ine-chemical inertness ephezulu, ixhathisa ukuguguleka okuvela kwi-acid kunye ne-alkali media ezininzi (ngaphandle kwe-hydrofluoric acid kunye ne-alkalis ezishushu ezixineneyo). Igcina ukusebenza okuzinzileyo phantsi kokuvezwa ixesha elide kumaqondo obushushu aphezulu (ubushushu obuphezulu benkonzo ukuya kuthi ga kwi-850°C) kunye neemeko zokusebenza ezinzima, kunye nobomi benkonzo obudlula kakhulu obo bezinto zemveli zokukhusela isinyithi.
I-ZTA ceramic lining isetyenziswa kakhulu kumashishini anomonakalo omkhulu, kuquka ukuveliswa kwamandla obushushu, ukumba, ukuvelisa isamente, ukunyibilikisa intsimbi, kunye neenkqubo zokuphatha izinto. Iindawo ezithile zokusetyenziswa ziquka abahluli beenkanyamba, iingqiniba zepayipi, ii-impellers zefeni, ii-chutes, ii-hoppers, kunye nezixhobo ezahlukeneyo zokwahlulahlula i-powder. Iindlela zayo zokufakela zahlukile, ezifana nokubopha, ukubholita, okanye ukubethela okumiselweyo, okukhusela ngempumelelo izixhobo eziphantsi komhlaba. Oku kunciphisa kakhulu amaxesha okugcinwa kwexesha lokungasebenzi kunye neendleko zemveliso ezibangelwa kukuguguleka, kuphucula ukusebenza kakuhle kwenkqubo kunye nokhuseleko.
Ngamafutshane, i-ZTA alumina ceramic lining ibe yinto ebalulekileyo kwezobugcisa kwicandelo lokukhusela ukuguguleka kwemizi-mveliso, ngenxa yoyilo lwayo oluhlanganisiweyo oluphuculwe ngokwesayensi kunye nokusebenza okugqwesileyo okuqinisekisiweyo. Inika isiqinisekiso esithembekileyo sokusebenza okuzinzileyo kwexesha elide kwezixhobo kwiindawo ezirhabaxa, inika iingenelo ezibalulekileyo kwezoqoqosho kunye nexabiso lokusetyenziswa. Uphando oluqhubekayo kwizixhobo kunye nokucubungula luya kwandisa ngakumbi imida yalo yokusebenza kunye noluhlu lwezicelo.
