Ukulungiswa komgubo
Umgubo weAluminailungiswa ibe ngumgubo ngokweemfuno ezahlukeneyo zemveliso kunye nenkqubo yokubumba eyahlukileyo.Ubungakanani besuntswana lomgubo lingaphantsi kwe-1μm.Ukuba kuyimfuneko ukuvelisa iimveliso ze-alumina ze-ceramic zokucoceka okuphezulu, ngaphezu kobunyulu be-alumina kufuneka ilawulwe kwi-99.99%, kufuneka kwakhona iqhube inkqubo yokugaya i-ultrafine ukwenza i-particle yayo yokusabalalisa iyunifomu.
Xa usebenzisa ukubunjwa kwe-extrusion okanye ukubunjwa kwenaliti, i-binder kunye ne-agent yeplastiki kufuneka ifakwe kumgubo, ngokubanzi kumlinganiselo wobunzima be-10-30% yeplastiki ye-thermoplastic okanye i-resin, i-organic binder kufuneka ixutywe kunye nomgubo we-alumina kwi-150-200 ℃ ubushushu ngokulinganayo, ukwenzela ukuququzelela umsebenzi wokubumba.
Izinto zomgubo ezenziwe ngenkqubo yokucinezela eshushu akufuneki ukuba zongeze i-binder.Ukuba ukusetyenziswa kwe-semi-automatic okanye ngokuzenzekelayo ukubumba ucinezela owomileyo, kukho iimfuno ezikhethekileyo zobugcisa kumgubo, kufuneka sisebenzise indlela yokutshiza yegranulation ukunyanga umgubo, wenze kubonakale ngathi singqukuva, ukuze kuphuculwe ubumanzi bomgubo, kulula. ukugcwalisa udonga lokubumba ngokuzenzekelayo ekubumbeni.Ukutshiza i-granulation yomgubo iyafuneka ngexesha lokucinezela okomileyo, kunye ne-polyvinyl alcohol yaziswa njenge-binder.Kwiminyaka yakutshanje, iziko lophando eShanghai liphuhlise iparafini enyibilikayo emanzini njengesibophelelo sokutshiza igranulation ye-Al2O3, enolwelo olulungileyo phantsi kokufudumeza.Umgubo emva kwegranulation yesitshizi kufuneka ube nolwelo olulungileyo, ingxinano ekhululekileyo, ukuqukuqela kweAngle yobushushu bokukhuhlana ngaphantsi kwe-30℃, umlinganiselo ofanelekileyo wobungakanani bamasuntswana kunye nezinye iimeko, ukuze ufumane ingxinano ephezulu yohlaza olucacileyo.
Indlela yokubumba
Iindlela zokubumba zeiimveliso ze-alumina ceramiczibandakanya ukucinezela okomileyo, i-grouting, i-extrusion, i-isostatic ebandayo ecinezelayo, inaliti, i-flow casting, i-hot pressing kunye ne-isostatic eshushu yokucinezela.Kwiminyaka yakutshanje ekhaya nakwamanye amazwe kukwaphuhliswe ukubumba isihluzi soxinzelelo, ukubumba inaliti yokuqinisa ngokuthe ngqo, ukubumba inaliti yejeli, ukubumba inaliti ye-centrifugal kunye neendlela zobugcisa zokubumba simahla.Iimilo ezahlukeneyo, ubukhulu, iimilo ezintsonkothileyo kunye nokuchaneka kweemveliso kufuna iindlela ezahlukeneyo zokubumba.
