Mipira ya Ceramic imapereka mawonekedwe owoneka bwino pamapulogalamu omwe amawonetsedwa ndi mankhwala oopsa kapena malo omwe ali ndi kutentha kwambiri. Pazinthu monga mapampu amankhwala ndi ndodo zobowola, pomwe zida zachikale zimalephera, mipira ya ceramic imapereka moyo wautali, kuchepa kwachangu, komanso magwiridwe antchito ovomerezeka.
Mipira ya Alumina Ceramic
Chifukwa cha kukana kwake kwa dzimbiri komanso kutentha kwambiri, alumina oxide (AL2O3) ndi chisankho chodziwika bwino pamipira ya ceramic. Zida zopangira zimagwiritsa ntchito mipira ya alumina oxide kuti iwonjezere magwiridwe antchito. Poyerekeza ndi anzawo achitsulo, mipira ya alumina oxide imakhala yopepuka, yolimba, yosalala, yolimba, yosagwira dzimbiri, imafunikira mafuta ochepa, ndipo imakhala ndi kukulitsa kwamafuta ochepa, zomwe zimapangitsa kuti kubereka kugwire ntchito mwachangu komanso kutentha kwapantchito ndi torque yochepa. Mipira ya aluminiyamu ya ceramic imagwiritsidwa ntchito kwambiri m'mafakitale a petroleum, mankhwala, feteleza, gasi, ndi kuteteza chilengedwe monga zothandizira mu riyakitala yophimba zinthu zothandizira ndi kulongedza nsanja.
Mipira ya Ceramic ya Zirconia
Ndi chinthu champhamvu chomwe chimagwira ntchito bwino pa kutentha kofika pa 1000°F (538°C) ndipo chimagwira ntchito bwino m’mikhalidwe monga zitsulo zosungunuka, zosungunulira organic, caustics, ndi ma asidi ambiri. Imagwiritsidwa ntchito nthawi zambiri ngati valavu yoyang'anira kayendedwe ka kayendedwe kake chifukwa cha kulimba kwake ku ma abrasion ndi dzimbiri.
Mipira ya Silicon Nitride Ceramic
Mipira ya Ceramic yopangidwa ndi silicon nitride (Si3N4) imagwiritsidwa ntchito nthawi zambiri pama bere chifukwa cha kukana kwawo kutentha kwambiri komanso kugundana kochepa. Amagwiritsidwanso ntchito pafupipafupi m'magawo kuphatikiza zida zopangira zitsulo, ma turbines a gasi, zida zama injini zamagalimoto, zonyamula zonse za ceramic, zankhondo ndi chitetezo, komanso zakuthambo.
M'mapulogalamu omwe amafunikira kusinthasintha kothamanga kwambiri, zitsulo zonse za ceramic ndi hybrid ceramic bearings zimagwiritsa ntchito mipira ya silicon nitride. Silicon nitride imakhala ndi kachulukidwe kochepera theka la chitsulo, kumachepetsa mphamvu yapakati pakasinthasintha, zomwe zimapangitsa kuti pakhale kuthamanga kwambiri.
Ndiwopanda magetsi ndipo ndi oyenera kugwiritsa ntchito ngati ma fani amagetsi amagetsi a AC ndi DC ndi ma jenereta. Silicon nitride ball bearings ikuyamba kukhala muyezo wamakampani popanga ma mota amagetsi pamagalimoto amagetsi ndi osayendetsa.
Silicon nitride yosagwiritsa ntchito maginito imapangitsa kukhala chinthu chabwino kwambiri kuti chigwiritsidwe ntchito pamapulogalamu omwe amayenera kupirira maginito. Mphamvu ya maginito kapena ma spinning torque ikhoza kusokonekera ngati mipira yachitsulo ikagwiritsidwa ntchito pazinthu zina. Kumene kuli maginito, ma bearing a silicon nitride ball ndi oyenera kugwiritsidwa ntchito popanga zida za semiconductor ndi zida zowunikira zamankhwala.
