Lefapheng la ho hanyetsa ho tlola ha indasteri, ditharollo tsa setso tsa thepa e le nngwe ha di sa lekana ho fihlela ditlhoko tse rarahaneng tsa ho tlola ho hoholo le tshusumetso e matla maemong a fapaneng a mosebetsi. Poleiti ya rabara-ceramic ya boraro ho e nngwe e kopaneng, e le tharollo e phetohelang, e fihletse katleho tshebetsong ya thepa ka moralo wa sebopeho sa metswako ya mekhahlelo e meraro: lera la ceramic le hanela ho tlola, lera la rabara le monya tshusumetso, mme poleiti ya tshepe e fana ka tshehetso. Thepa ena e hanelang ho tlola e kopaneng jwale e sebediswa haholo diindastering tse boima tse kang motlakase, merafo le tshepe, mme e se e le e nngwe ya mahlale a mantlha a ho atolosa nako ya bophelo ba disebediswa le ho fokotsa ditjeo tsa tlhokomelo.
Thepoleiti e kopantsoeng ea rabara-ceramic e meraro ho e 'ngoee entsoe ka lipoleiti tsa tšepe tse sa tsofaleng tsa letsopa, rabara le tšepe. Lera la ceramic le sebelisa phofo ea alumina e hloekileng haholo (92%, 95%) e le thepa e tala, e entsoeng ka ho hatelloa ka omileng kapa ho hatelloa ka isostatic. Kamora ho siloa mochesong o phahameng haholo oa 1700°C, ho thehoa sebopeho se teteaneng se nang le boima ba Mohs ba 9 le boima ba ≥ 3.65 g/cm³. Ebe, ceramic e sa tsofaleng ea alumina le lera la rabara lia laminate 'me li beoa ka har'a hlobo. Karabelo ea vulcanization (140-160°C) e etsoa tlas'a mocheso o phahameng le khatello e phahameng. Limolek'hule tsa rabara li theha maqhama a lik'hemik'hale le bokaholimo ba ceramic. Pele ho vulcanization, poleiti ea tšepe e beoa holim'a rabara, 'me likarolo tse tharo lia tiea ka vulcanization ea bobeli.
Poleiti e kopantsoeng ea rabara-ceramic ea likarolo tse tharo ho e 'ngoe, ka ts'ebetso ea eona e ikhethang, e ka sebelisoa maemong a latelang:
1. E ka sebelisoa lits'ebetsong tsa ts'ebetso ea thepa e tsofalang haholo, joalo ka hopper ea crusher ea merafo kapa chute ea sintering ea leloala la tšepe. E ka mamella ho senyeha ha thepa e bohale joalo ka tšepe ea tšepe le lehlabathe la quartz, 'me nako ea ts'ebeletso ea eona e feta makhetlo a mahlano ho feta lipoleiti tse tloaelehileng tsa tšepe.
2. E loketse maemo a ka bang mongobo le ho thella, joalo ka moropa o tsamaisang mashala oa mabanta a koung le a koung, le li-conveyor tsa lebanta lifemeng tsa ho sebetsana le lijo. Likaroloana tsa ceramic tse ka har'a poleiti ea rabara-ceramic tse tharo-ka-ngoe li fana ka matla a phahameng a khohlano. Coefficient ea ho hanyetsa ho thella ha metsi ke ≥ 0.5, e thibelang thepa ho thella.
3. E loketse ho sebelisoa libakeng tse nang le mocheso o phahameng le tse senyang, joalo ka mohala oa ho fetisa o chesang mechineng ea tšepe (li-billet tsa tšepe tse khubelu ho 200℃), le litanka tsa ho hlatsoa asiti lifemeng tsa lik'hemik'hale. Rabara e hanelang mocheso le li-ceramic tse sa sebetseng li ka thibela ho tsamaisoa ha mocheso le khoholeho ea lik'hemik'hale ka katleho.
4. Bakeng sa libaka tse nang le phapang e kholo ea ho theoha, joalo ka liphaephe tsa mashala tse ntšang mashala lifemeng tsa motlakase tse chesang (tse nang le phapang ea ho theoha ea limithara tse fetang 20) le li-silo tsa thepa e tala lifemeng tsa samente, li-ceramic tse sa tsofaleng li sebelisoa ho hasanya matla a ho thulana, 'me likarolo tsa rabara li sebelisoa bakeng sa ho monya ho phatloha ho thibela lipoleiti tsa ho robeha hore li se ke tsa petsoha.
Ho tloha merafong ho ea likoung, ho tloha lifemeng tsa tšepe ho ea lifemeng tsa motlakase, poleiti ea rabara-ceramic ea likarolo tse tharo ho e 'ngoe e ntlafalitse maemo a ho hanyetsa ho tsofala ha indasteri ka sebopeho se sireletsang se tharo. Boleng ba eona ha bo felle feela bophelong ba eona ba lilemo tse 10 (ho feta thepa ea setso ka makhetlo a 3-5), empa hape bo le ho boloka litšenyehelo tse kholo tse fihletsoeng ka ho fokotsa nako ea ho se sebetse le tlhokomelo. Ka ho kenngoa ha thepa e ncha le lits'ebetso tse bohlale, theknoloji ena ea likarolo e tla tsoela pele ho khanna phetoho ea lisebelisoa tse boima tsa indasteri ho ea ho tšoarella ho hoholo, tšebeliso e tlase ea matla, le likarolo tse se nang tlhokomelo.
