Mapepala a Ceramic Osavala Alumina: Mayankho Ogwira Ntchito Kwambiri Pantchito Zamakampani

Mapepala a ceramic osatha kutha a Alumina ndi zipangizo za ceramic zamafakitale zopangidwa makamaka ndi aluminium oxide (Al₂O₃) ndipo zimatenthedwa kutentha kwambiri. Mapepala awa nthawi zambiri amafika pa kuuma kwa Mohs kwa 8-9. Kudzera mu mapangidwe apadera a pamwamba, monga malo otsika ozungulira omwe amapanga gridi, mafunde, kapena malo osungira guluu okhala ndi madontho, mphamvu yolumikizirana ndi zitsulo imawonjezeka kwambiri. Pogwiritsa ntchito zomatira zapadera za ceramic-metal, mapepala awa amatha kugwira ntchito mokhazikika m'malo otentha mpaka 350°C kwa nthawi yayitali, ndipo zinthu zina zimatha kupirira kutentha kwa 500°C. Kuchuluka kwawo ndi pafupifupi 3.6 g/cm³, theka lokha la chitsulo, zomwe zimachepetsa bwino katundu wa zida.

Mapepala a ceramic osatha kuvala a AluminaZimapereka mphamvu yolimba kwambiri yolimbana ndi kusowa kwa zinthu, ndipo nthawi yogwira ntchito imatha kupitirira nthawi 100 kuposa chitsulo cha manganese komanso kupitirira nthawi 20 kuposa chitsulo chapamwamba cha chromium, kutengera momwe zimagwirira ntchito. Mapepala okhala ndi mfundo zozungulira ndi mizere yopingasa amagwiritsa ntchito kapangidwe ka guluu, komwe kumalola guluu kuyenda ndikudzaza pansi pa kupanikizika, ndikupanga malo olumikizirana omwe amalimbitsa kwambiri kudalirika kwa kukhazikitsa. Makhalidwe amenewa amawapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale monga mphamvu ya kutentha, chitsulo, simenti, ndi migodi, makamaka m'malo owonongeka kwambiri monga mapaipi otulutsira malasha, zolekanitsa ufa wosalala komanso wosalala, ndi ma fan impellers.
