Iibhola Zokugaya zeAlumina
Ingcaciso yeMveliso
Iibhola zokugaya ze-Alumina,Zenziwe nge-aluminium oxide (Al₂O₃) njengenxalenye yazo ephambili kwaye zisebenzisa inkqubo yokusila i-ceramic, ziibhola ze-ceramic ezisebenzayo ezenzelwe ngokukodwa ukugaya, ukutyumza, kunye nokusasaza izixhobo. Zezinye zezona zixhobo zokugaya ezisetyenziswa kakhulu kwizicelo zokugaya zoshishino (ezifana ne-ceramics, ii-coating, kunye neeminerali).
Iibhola zokugaya ze-alumina zahlulwe ngokomxholo wazo we-alumina zibe ziintlobo ezintathu: iibhola ze-alumina eziphakathi (60%-65%), iibhola ze-alumina eziphakathi (75%-80%), kunye neebhola ze-alumina eziphezulu (ngaphezulu kwe-90%). Iibhola ze-alumina eziphezulu zahlulwe zibe ziiklasi ze-90-ceramic, 92-ceramic, 95-ceramic, kunye ne-99-ceramic, apho i-92-ceramic iyeyona isetyenziswa kakhulu ngenxa yokusebenza kwayo okuphezulu. Ezi bhola zokugaya zinobunzima obuphezulu (ubulukhuni be-Mohs obuyi-9), uxinano oluphezulu (ngaphezulu kwe-3.6g/cm³), ukumelana nokuguguleka nokubola, kunye nokumelana nobushushu obuphezulu (1600°C), okwenza ukuba zifaneleke ukugrumba iiglaze ze-ceramic, izinto ezisetyenzisiweyo zeekhemikhali, kunye neeminerali zesinyithi.
Iimbonakalo:
Ukuqina Okuphezulu kunye nokumelana nokunxiba okunamandla:Ubunzima beMohs bufikelela kwi-9 (kufuphi nedayimani), kunye nesantya sokuguguleka esiphantsi (<0.03%/1,000 iiyure kwiimodeli ezicocekileyo kakhulu). Iyamelana nokuqhekeka kunye nokungcola ngexesha lokusila ixesha elide, nto leyo ebangela ubomi benkonzo ende.
Uxinano oluPhezulu kunye nokusebenza kakuhle kokusila:Ngobuninzi bayo obuyi-3.6-3.9 g/cm³, inika amandla amakhulu okuchukumisa kunye nokucheba ngexesha lokusila, iphucula ngokukhawuleza izinto ukuya kwinqanaba le-micron, ngobuchule obuphezulu ngama-20%-30% kuneebhola ze-aluminium eziphakathi neziphantsi.
Ukungcola okuphantsi kunye nokuzinza kweekhemikhali:Iimodeli ezicocekileyo kakhulu ziqulathe ukungcola okungaphantsi kwe-1% (okufana ne-Fe₂O₃), okuthintela ukungcoliswa kwezinto. Zimelana nee-asidi ezininzi kunye nee-alkali (ngaphandle kwee-asidi ezinamandla kunye nee-alkali ezixineneyo), amaqondo obushushu aphezulu (ngaphezulu kwe-800°C), kwaye zifanelekile kwiinkqubo ezahlukeneyo zokusila.
Ubungakanani obuguquguqukayo kunye nokuhambelana:Ifumaneka ngobubanzi ukusuka kwi-0.3 ukuya kwi-20 mm, ibhola ingasetyenziswa ngobukhulu obunye okanye obuxutyiweyo, ihambelana neebhola, iisanti, kunye nezinye izixhobo, ihlangabezana nazo zonke iimfuno ukusuka ekugayweni okurhabaxa ukuya ekugayweni okucolekileyo.
