Mbale ya ceramic ya silicon carbide

Mu dziko la kupanga zinthu molondola, pali chinthu chomwe chimathandiza pang'onopang'ono chitukuko cha mafakitale ambiri apamwamba - ndi cholimba kuposa chitsulo, chosatentha kwambiri kuposa graphite, koma nthawi zonse chimakhala ndi thupi lopepuka. Izi ndimbale ya ceramic ya silicon carbide, "zinthu zolemera" zofunika kwambiri m'makampani amakono.
1, Mphatso za chilengedwe ndi kupangika kwa nzeru za anthu
Silicon carbide (SiC) si chinthu chongochitika mwangozi mu labotale. Kale mu 1893, asayansi adapeza mchere uwu womwe umapezeka mwachilengedwe. Masiku ano, pogwiritsa ntchito ukadaulo wopangira kutentha kwambiri kuti agwirizanenso mchenga wa silicon ndi magwero a kaboni pa kutentha kwambiri, ma ceramic a silicon carbide apamwamba kwambiri amapangidwa. Zinthuzi zimaphatikiza bwino kukhazikika kwa ma ceramic ndi mawonekedwe a ma semiconductors, ndikupanga jini yapadera yazinthu.
2, Chotsani ma crypt asanu ofunikira
1. Choteteza kutentha kwambiri
Mu nyengo yovuta kwambiri ya 1350 ℃, zitsulo wamba zakhala zofewa kale komanso zopindika, pomwe mbale za ceramic za silicon carbide zimatha kusungabe umphumphu wa kapangidwe kake. Kukana kutentha kwambiri kumeneku kumapangitsa kuti ikhale chisankho chabwino kwambiri m'magawo monga zida zosungunulira ndi injini zamlengalenga.
2. Chishango choteteza champhamvu kwambiri
Kulimba kwake, komwe ndi kwachiwiri pambuyo pa diamondi, kumalola mbale za silicon carbide kuti zisawonongeke mosavuta ndi kuwonongeka kwa chitsulo chosungunuka. Pa mzere wopangira aluminiyamu, nthawi yake yogwira ntchito imakulitsidwa ndi nthawi zoposa 5 poyerekeza ndi zinthu zachikhalidwe zotsutsa.
3. Waluso pakuwongolera kutentha
Mosiyana ndi mphamvu ya "kuteteza" ya zoumba wamba, zoumba za silicon carbide zimakhala ndi mphamvu yabwino kwambiri yotenthetsera kutentha. Zipangizo "zopumira" izi zimatha kusamutsa kutentha mwachangu pamene zikusunga kukhazikika kwake, zomwe zimapangitsa kuti zikhale zothandiza kwambiri pakuchotsa kutentha kwa semiconductor.

4. Wopepuka Wapainia
Pa mphamvu yomweyo, kulemera kwake ndi gawo limodzi mwa magawo atatu okha a chitsulo. Khalidwe ili la "kunyamula zinthu zolemera mopepuka" limabweretsa njira zatsopano zochepetsera kulemera m'magawo monga zida zatsopano zamagetsi ndi zoyendera sitima.
5. Chitetezo cha Mankhwala
Poyang'anizana ndi zinthu zowononga kwambiri, ziwiya za silicon carbide zimaonetsa kukhazikika kodabwitsa. Mu reactor ya mankhwala, zimakhala ngati choteteza chomwe sichichita dzimbiri, zomwe zimaonetsetsa kuti ntchitoyo ndi yotetezeka.
3, mwayi wopanda malire wosinthira tsogolo
Kuchokera ku gawo lonyamula katundu la maselo a photovoltaic mpaka ku zigawo zolondola zosatha ntchito za makina olondola, kuyambira pansi pa kutentha kwa ma semiconductor chips mpaka gawo losefera la zida zoteteza chilengedwe, mbale za silicon carbide ceramic zikukonzanso malire a magwiridwe antchito a zipangizo zamafakitale. M'magawo anzeru monga mphamvu zatsopano, zambiri zamagetsi, ndi zida zapamwamba, zipangizo za silicon carbide ceramic zikuyendetsa pang'onopang'ono kukweza mafakitale.
Monga katswiri wopanga ukadaulo wotanganidwa kwambiri ndi ntchito za ziwiya zapadera za silicon, nthawi zonse timadzipereka kupititsa patsogolo magwiridwe antchito a zinthu za silicon carbide. Mwa kupitilizabe kukonza njira zoyeretsera ndi njira zochizira pamwamba, bolodi lililonse la ceramic limakhala luso la mafakitale lomwe lingathe kupirira mayeso a nthawi. Tsogolo lili pano, tiyeni tiwone pamodzi kukongola kwapadera kwa ziwiya za silicon carbide zomwe zikufalikira m'minda yambiri.
Shandong Zhongpeng nthawi zonse amatsatira lingaliro lakuti "kupanga zinthu zatsopano kumayendetsa patsogolo mafakitale", ndipo akuyembekezera kugwira ntchito ndi ogwirizana nawo padziko lonse lapansi kuti afufuze njira zopanda malire zogwiritsira ntchito zinthu za silicon carbide.
