Zipangizo zoyenera zamkati zimatsimikizira kudalirika kwa mafakitale—makamaka m'mikhalidwe yovuta kwambiri.Njerwa za alumina zophimba mkati, yopangidwa ndi 75–99.99% ya Al₂O₃, yakhala chisankho chofunikira kwambiri m'magawo ofunikira, kuthetsa mavuto omwe ma liners achikhalidwe sangathe kuthana nawo. Kuyambira ma uvuni a simenti otentha kwambiri mpaka zomera zamafuta, ntchito zawo zosiyanasiyana zimapereka phindu losayerekezeka komwe magwiridwe antchito ndi ofunika kwambiri. Onani momwe amakhudzira kusintha kwawo m'mafakitale asanu akuluakulu.
Kupanga Simenti
Ma uvuni ozungulira ndi ma preheater amakumana ndi kutentha kwa 1400°C+, clinker yolimba, komanso kuukira kwa alkaline. Njerwa za alumina (85–95% Al₂O₃) zimapereka kuuma kwa Mohs 9 komanso kukana kwambiri, kukana kuwonongeka komanso kuchepetsa kutaya kutentha ndi 25–30%.
Kukonza Migodi ndi Migodi
Madothi, miyala, ndi matope amawononga zida zachitsulo mwachangu. Ma alumina liners (90% + Al₂O₃) amapereka kukana kuwonongeka kwa chitsulo cha manganese ka 10-20, komwe ndi koyenera kwambiri pa mapaipi, ma ball mills, ndi ma chutes. Amachepetsa kugwiritsidwa ntchito kwa media ndi 30% ndipo amaletsa kuipitsidwa kwa zinthu, zomwe ndizofunikira kwambiri pakupanga mchere woyeretsedwa kwambiri. Mgodi wa mkuwa ku South America wawonjezera nthawi ya mapaipi a matope kuyambira miyezi itatu mpaka zaka zinayi, kuchotsa ndalama zosinthira pamwezi komanso kutseka kosakonzekera.
Kupanga Mphamvu
Mitengo yotenthetsera, biomass, ndi yotaya mphamvu imafunika ma liners omwe amapirira kutentha kwambiri, mpweya wotuluka m'madzi, ndi kukokoloka kwa phulusa. Njerwa za alumina zimalimbana ndi kutentha kwa 500°C+ komanso SOx/NOx yowononga, zomwe zimapangitsa kuti chitsulo cha alloy chizigwira ntchito bwino kuposa chitsulo chosungunuka.
Makampani a Mankhwala ndi Mafuta
Ma asidi amphamvu, alkali, ndi mchere wosungunuka zimawononga zitsulo wamba. Njerwa za alumina zoyera kwambiri (99%+ Al₂O₃) sizigwira ntchito bwino, zimapirira 98% sulfuric acid ndi 50% sodium hydroxide.
Semiconductor & High-Tech
Njerwa za alumina zoyera kwambiri (99.99% Al₂O₃) zimathandiza kupanga ma semiconductor opanda kuipitsidwa. Sizimatulutsa mabowo komanso sizimayambitsa kuipitsidwa, zimaletsa kutuluka kwa ayoni achitsulo, zomwe zimapangitsa kuti chitsulocho chikhale chochepera 1ppm pa tchipisi ta 7nm/5nm.
Pa ntchito zonse, njerwa za alumina zimapereka chitetezo chokhalitsa komanso chotsika mtengo chomwe chimapangitsa kuti ntchito ikhale yabwino kwambiri. Kusinthasintha kwawo ku kutentha, kusweka, dzimbiri, ndi kuipitsidwa kumawapangitsa kukhala njira yabwino yochepetsera ndalama ndikuwonjezera zokolola.
Kodi mwakonzeka kupeza yankho lanu lopangidwa mwaluso? Akatswiri athu adzayesa zosowa zanu—kuyambira ma uvuni a simenti otentha kwambiri mpaka zida za semiconductor zoyera kwambiri—ndipo adzakupatsani ma alumina liners opangidwa mwamakonda. Lumikizanani nafe lero kuti mupeze mtengo kapena upangiri waukadaulo. Njira yolimba kwambiri yopangira ma liners m'makampani anu ili pafupi kukambirana nanu.
