Tokisetso ea phofo
Alumina phofoe lokiselitsoe ka thepa ea phofo ho latela litlhoko tse fapaneng tsa sehlahisoa le mokhoa o fapaneng oa ho bopa.The phatsa boholo ba phofo ke ka tlaase ho 1μm.Haeba ho hlokahala ho etsa lihlahisoa tse phahameng tsa alumina ceramic tse hloekileng, ntle le bohloeki ba alumina e lokela ho laoloa ka 99.99%, e boetse e hloka ho etsa ts'ebetso ea ho sila ea ultrafine ho etsa junifomo ea kabo ea boholo ba likaroloana.
Ha o sebelisa extrusion molding kapa ente e entsoeng, binder le moemeli oa polasetiki li lokela ho kenngoa ka phofo, ka kakaretso ka tekanyo ea boima ba 10-30% ea polasetiki ea thermoplastic kapa resin, organic binder e lokela ho tsoakoa le phofo ea alumina ka mocheso oa 150-200 ℃ ka ho lekana. molemong oa ho nolofatsa ts'ebetso ea ho bopa.
Lisebelisoa tsa phofo tse entsoeng ka mokhoa o chesang oa ho hatisa ha li hloke ho eketsa binder.Haeba tšebeliso ea semi-automatic kapa jarolla ka ho iketsa e omeletseng ho bōpa, ho na le litlhoko tse khethehileng tsa botekgeniki bakeng sa phofo, re lokela ho sebelisa spray granulation mokhoa ho tšoara phofo, etsa hore ho bonahala eka spherical, e le hore ho ntlafatsa fluidity ea phofo, bonolo. ho tlatsa lebota la hlobo ka tsela e iketsang ha ho etsoa.Ho fafatsa granulation ea phofo e hlokahalang nakong ea khatiso e omileng, 'me joala ea polyvinyl e hlahisoa e le binder.Lilemong tsa morao tjena, setsi sa lipatlisiso Shanghai se thehile parafine e qhibilihang ka metsing e le se tlamellang ho fafatsa granulation ea Al2O3, e nang le mokelikeli o motle ha ho futhumatsa.Phofo ka mor'a ho fafatsa granulation e tlameha ho ba le metsi a matle, boima bo hlephileng, ho phalla ha mocheso oa Angle friction ka tlase ho 30 ℃, karo-karolelano ea boholo ba likaroloana le maemo a mang, e le ho fumana boholo bo phahameng ba botala bo hlakileng.
Mokhoa oa ho bopa
Mekhoa ea ho bopa ealihlahisoa tsa alumina ceramickenyeletsa khatello e omileng, grouting, extrusion, batang isostatic pressing, ente, phallo casting, hot tobetsa le hot isostatic tobetsa.Lilemong tsa morao tjena lapeng le kantle ho naha ho boetse ho ntlafalitse mochini oa mochini oa khatello, ho bopa ente ea ho tiisa ka kotloloho, ho bopa ente ea gel, ho bopa ente ea centrifugal le mekhoa ea theknoloji ea ho bopa e sa lefelloeng.Libopeho tse fapaneng, boholo, libopeho tse rarahaneng le ho nepahala ha lihlahisoa li hloka mekhoa e fapaneng ea ho bopa.
