Amashubhu e-liner e-alumina ceramic amelana nokugqokwakuyisici esibalulekile sokuvikela esisetshenziswa kakhulu ezinhlelweni zamapayipi ezimboni ezihlushwa ukuklwebheka okukhulu. Ukwakheka kwawo okuyinhloko yi-alpha-alumina (Al₂O₃), okuqukethwe kuvame ukuba phakathi kuka-92% kuya ku-99.5%. Lokhu okwenziwe kwenziwa ngenqubo yokushisa ephezulu, okuholela ebulukhunini obungavamile, obunobunzima be-Rockwell (HRA) obungu-≥85 kanye nesilinganiso sobunzima be-Mohs esingu-9, esilandela idayimane kuphela. Lawa mapayipi e-liner aboshelwe ngokuphephile noma afakwe ngomshini odongeni lwangaphakathi lwamapayipi ensimbi, akha isithiyo esiqinile sokuvikela esihlukanisa ngempumelelo indawo egelezayo ekukhuculweni okuqondile nasekugugeni emzimbeni wamapayipi ensimbi.
Ukusebenza kwazo okuphezulu kuvela ezimpahleni ezingokwemvelo ze-alumina ceramics. Ngaphezu kobulukhuni obuphezulu, ubuningi bazo buvame ukuba ngaphezulu kuka-3.6 g/cm³, ngamandla okucindezela adlula u-850 MPa. Ukumelana nokuguguleka kwalezi zingcezu ze-ceramic cishe kuphindwe izikhathi ezingu-266 kunensimbi ye-manganese kanye nezikhathi ezingu-171.5 kunensimbi ephezulu ye-chromium, okwandisa impilo yesevisi yemishini ngezikhathi ezingu-5 kuya kwezingu-10 ngaphansi kwezimo zokusebenza ezifanayo. Ubuso bazo obubushelelezi kanye ne-coefficient ephansi yokungqubuzana kunciphisa ngempumelelo ukumelana kokudlulisa. Ziphinde zibe nokumelana okuhle kakhulu kokugqwala, zibekezelela iningi lamakhemikhali ngaphandle kwe-hydrofluoric acid kanye nama-alkali aqinile ashisayo.
Lo mkhiqizo usetshenziswa kakhulu emikhakheni yezimboni enezidingo eziqinile zokumelana nokuguguleka. Izicelo ezijwayelekile zifaka phakathi ukuthutha amalahle, ukudla uphethiloli okucoliwe, kanye nezinhlelo zokususa umlotha ezitshalweni zamandla ezishisayo; amapayipi okuthutha umpuphu wamalahle kanye ne-ore acoliwe ezitshalweni zensimbi; imigqa yokudlulisa umpuphu wamalahle, i-clinker, kanye namalahle ezitshalweni zesamente; kanye nezinhlelo zokuthutha uthuli oluhlanganisiwe kanye nolwe-concentrate emisebenzini yezimayini. Iphinde isetshenziswe kabanzi emiphayiphini yokudlulisa umoya kanye ne-hydraulic ezimbonini zensimbi, zamakhemikhali, kanye nezinye, ibhekana ngempumelelo nezinkinga zokuguga okusheshayo kwephayiphi, ukubhoboza, kanye nokuvuza okubangelwa ukukhuhla izinto isikhathi eside.
Ngamafuphi, amashubhu e-alumina ceramic liner angagugi ahlinzeka ngesivikelo sesikhathi eside samapayipi okuthutha ezimbonini ngenxa yobunzima bawo obuphezulu kakhulu, ukuguguleka okumangalisayo, kanye nokumelana nokugqwala. Anciphisa kakhulu imvamisa yokuvalwa kwezindleko zokulungisa nokufaka esikhundleni okubangelwa ukuguguleka kwamapayipi, okuthuthukisa ukusebenza kahle okuqhubekayo kanye nokuphepha kwezinhlelo zokukhiqiza. Amelela ikhambi lokuvikela eliqinisekisiwe nelingabizi kakhulu.
