Iibhola zeCeramic zibonelela ngeempawu zokusebenza ezibalaseleyo kwizicelo ezivezwe kwiikhemikhali ezinzima okanye iimeko ezinobushushu obuphezulu kakhulu. Kwizicelo ezinjengeempompo zekhemikhali kunye neerodi zokubhola, apho izinto zemveli zingaphumeleli, iibhola ze-ceramic zinika ubomi obude, ukuncipha kokunxiba, kwaye mhlawumbi nokusebenza okwamkelekileyo.
Iibhola zeCeramic zeAlumina
Ngenxa yokumelana kwayo okuphezulu kwe-corrosion kunye neempawu zokushisa eziphezulu zokusebenza, i-alumina oxide (AL2O3) lukhetho oludumileyo kwiibhola ze-ceramic. Izixhobo zokulungisa zisebenzisa iibhola ze-alumina oxide ukuphucula ukusebenza. Xa kuthelekiswa noogxa babo bentsimbi, iibhola ze-alumina oxide zikhaphukhaphu ngakumbi, ziqinile, zigudileyo, ziqinile, zimelana ne-corrosion, zifuna ukuthambisa okuncinci, kunye nokwandiswa kwe-thermal esezantsi, evumela ukuthwala ukuba kusebenze ngesantya esikhulu kunye namaqondo obushushu okusebenza kunye ne-torque encinci. Iibhola ze-alumina ze-ceramic zisetyenziswa kakhulu kwipetroleum, kwikhemikhali, kwisichumisi, kwirhasi yendalo, nakumashishini okhuselo lokusingqongileyo njengezinto ezikhuthazayo kwireactor egqumayo kunye netower packing.
Iibhola zeCeramic zeZirconia
Yinto eyomeleleyo esebenza ngokufanelekileyo kumaqondo obushushu ukuya kwi-1000°F (538°C) kwaye isebenza kakuhle kwiimeko eziquka isinyithi esinyibilikisiweyo, izinyibilikisi eziphilayo, i-caustics, kunye noninzi lweeasidi. Isetyenziswa rhoqo njengevalve yokukhangela ulawulo lokuqukuqela ngenxa yokunganyangeki kwayo kwi-abrasion kunye nokuhlwa.
Iibhola zeCeramic zeSilicon Nitride
Iibhola zeCeramic ezenziwe nge-silicon nitride (i-Si3N4) zisetyenziswa rhoqo kwiibheringi ngenxa yokumelana nobushushu obuqinileyo kunye nokukhuhlana okuphantsi. Zikwasetyenziswa rhoqo kumasimi abandakanya izixhobo zentsimbi, iiinjini zegesi, iinxalenye zenjini yeemoto, iibheringi zeceramic ezigcweleyo, umkhosi nokhuselo, kunye ne-aerospace.
Kwizicelo ezifuna ukujikeleza okuphezulu kwesantya esiphezulu, iibheringi ze-ceramic ezigcweleyo kunye ne-hybrid ceramic zisebenzisa iibhola ze-silicon nitride. I-Silicon nitride inoxinano olungaphantsi kwesiqingatha sentsimbi, inciphisa amandla e-centrifugal ngexesha lokujikeleza, evumela isantya esiphezulu sokusebenza.
Azikho umbane ezingasebenziyo kwaye zifanelekile kwizicelo ezifana neebheringi zeshaft yombane yee-AC kunye ne-DC kunye neejenereyitha. Iibheringi zebhola ze-Silicon nitride zikhawuleza zibe ngumgangatho woshishino kwimveliso yeemoto zombane zombane kunye nezithuthi ezingaqhubi.
Umgangatho ongeyo-magnetic weSilicon nitride wenza ukuba ibe yeyona nto ifanelekileyo yokusetyenziswa kwizicelo ekufuneka zimelane nemagnethi. Umhlaba wemagnethi okanye itorque ejikelezayo inokuphazamiseka ukuba iibhola zentsimbi zisetyenziswa kwizinto ezithile. Apho imagnethi ikhona, iibheringi zesilicon nitride zebhola zezona zilungele ukusetyenziswa kwizixhobo zokwenziwa kwesemiconductor kunye nezixhobo zonyango zokuxilonga.
