Iibhola zokuSila zeAlumina
Ingcaciso yeMveliso
I-alumina yokusila iibhola,ezenziwe nge-aluminium oxide (Al₂O₃) njengenxalenye yazo engundoqo kunye nokusebenzisa inkqubo ye-ceramic sintering, iibhola ze-ceramic ezisebenzayo ezilungiselelwe ngokukodwa ukugaya, ukutyumza, kunye nokusabalalisa izinto. Ziyenye yezona zinto zixhaphakileyo zisetyenziswa kwimidiya yokusila kwishishini lokusila izicelo (ezifana neekeramics, ii-coatings, kunye neeminerali).
Iibhola ze-alumina zokugaya zihlelwa ngomxholo wazo we-alumina kwiindidi ezintathu: iibhola ze-aluminium eziphakathi (60% -65%), iibhola ze-aluminium eziphakathi (75% -80%), kunye neebhola eziphezulu ze-aluminium (ngaphezu kwe-90%). Iibhola eziphezulu ze-aluminium zikwahlulahlula ngakumbi kwi-90-ceramic, i-92-ceramic, i-95-ceramic, kunye ne-99-ceramic grade, kunye ne-92-ceramic iyona nto isetyenziswa kakhulu ngenxa yokusebenza kwayo jikelele. Ezi bhola zokusila zibonakalisa ubulukhuni obuphezulu (ubunzima be-Mohs obuyi-9), ukuxinana okuphezulu (ngaphezulu kwe-3.6g/cm³), ukuguga kunye nokumelana nokugqwala, kunye nokumelana nobushushu obuphezulu (1600°C), kubenze bafanelekele ukugaywa kakuhle kwekheramic glaze, iikhemikhali ekrwada, kunye neeminerali zetsimbi.
Iimbonakalo:
Ubulukhuni obuPhezulu kunye nokuNxibelelana okuqinileyo:Ubunzima be-Mohs bufikelela kwi-9 (kufuphi nedayimane), kunye nezinga eliphantsi lokugqoka (<0.03% / iiyure ze-1,000 kwiimodeli ezicocekileyo). Ixhathisa i-brittleness kunye ne-debris ngexesha lokugaya ixesha elide, okubangelwa ubomi obude benkonzo.
Uxinaniso oluPhezulu kunye nokuSebenza okuPhezulu kokuSila:Ngoxinaniso olukhulu lwe-3.6-3.9 g/cm³, inika impembelelo eyomeleleyo kunye nemikhosi yokucheba ngexesha lokusila, ngokukhawuleza ukulungisa imathiriyeli ukuya kwinqanaba le-micron, kunye nokusebenza kakuhle kwe-20% -30% ephezulu kuneebhola ze-aluminiyam eziphakathi kunye nezisezantsi.
Ubumdaka obuphantsi kunye noZinzo lweMichiza:Iimodeli ezicocekileyo ziqulethe ukungcola okungaphantsi kwe-1% (ezifana ne-Fe₂O₃), ukukhusela ukungcoliswa kwezinto. Ukumelana nobuninzi be-acids kunye ne-alkali (ngaphandle kwee-acids ezigxininisiweyo ezinamandla kunye ne-alkalis), ukushisa okuphezulu (ngaphezulu kwe-800 ° C), kwaye ifanelekile kwiinkqubo ezahlukeneyo zokugaya.
Ubungakanani obuguquguqukayo kunye nokuhambelana:Ifumaneka kwi-diameters ukusuka kwi-0.3 ukuya kwi-20 mm, ibhola ingasetyenziselwa ubukhulu obubodwa okanye obuxubeneyo, obuhambelana neebhola zebhola, i-sand mill, kunye nezinye izixhobo, ukuhlangabezana nazo zonke iimfuno ukusuka kwi-coarse ukuya kwi-cone grinding.
