Ponena za "zoumba zadothi", anthu ambiri amaganizira kaye mbale zapakhomo, miphika yokongoletsera - yofooka komanso yofewa, yomwe imawoneka kuti siili yogwirizana ndi "makampani" kapena "yolimba". Koma pali mtundu wa ceramic womwe umaswa chithunzithunzi ichi. Kulimba kwake ndi kwachiwiri kwa diamondi, ndipo kumatha kupirira kutentha kwambiri, kukana dzimbiri, komanso kumateteza kutentha ndi kuyendetsa bwino, kukhala "kosinthasintha" m'mafakitale. Ndisilicon carbide ceramic.
Kuyambira zida zosatha ntchito m'migodi mpaka ma module amagetsi m'magalimoto atsopano amphamvu, kuyambira zida zotha ntchito kutentha kwambiri mumlengalenga mpaka zomatira zamakina za tsiku ndi tsiku, zomatira za silicon carbide zikuthandiza mwakachetechete kugwira ntchito bwino kwa mafakitale ambiri ndi mawonekedwe awo apadera. Lero, tiyeni tikambirane zomwe zimapangitsa kuti zomatira "zapadera" izi ziwonekere.
1、 Zovuta kwambiri: "chonyamulira" pankhani yolimbana ndi kuvala
Ubwino wodziwika bwino wa silicon carbide ceramics ndi kuuma kwake kwambiri komanso kukana kuwonongeka. Kuuma kwake kwa Mohs ndi kwachiwiri kwa diamondi yolimba kwambiri, yolimba kwambiri kuposa chitsulo wamba, chitsulo chosapanga dzimbiri, komanso alumina ceramics.
Khalidwe lolimba limeneli limaupangitsa kukhala wowala kwambiri pamene likufunika kukana kuwonongeka. Mwachitsanzo, m'mafakitale a migodi ndi zitsulo, zida zonyamulira matope ndi matope otayidwa (monga ma impeller a mapampu otayidwa ndi mapaipi) nthawi zambiri zimatsukidwa ndi tinthu ta mchere tolimba kwa nthawi yayitali, ndipo zitsulo wamba zimawonongeka mwachangu ndikutulutsa madzi. Zigawo zopangidwa ndi silicon carbide ceramics zimatha kupirira "kuwonongeka" kumeneku ndipo zimakhala ndi moyo wautali nthawi zingapo kapena kupitirira khumi kuposa zigawo zachitsulo, zomwe zimachepetsa kwambiri kuchuluka ndi mtengo wosinthira zida.
Sikuti m'mafakitale okha, timatha kuwonanso kupezeka kwake tsiku ndi tsiku - monga silicon carbide friction pair mu makina osindikizira. Chifukwa cha kukana kwake kutopa bwino, imaonetsetsa kuti zida sizikutuluka ndipo zimakhala ndi zotayika zochepa panthawi yozungulira mwachangu, zomwe zimathandiza kuti zipangizo monga mapampu amadzi ndi ma compressor zigwire ntchito bwino.
2、 "Kukana" Kwapamwamba: Kutchinjiriza Kutentha Kwambiri ndi Kudzimbiri
Kuwonjezera pa kuuma, ziwiya za silicon carbide zimakhalanso ndi kukana kutentha kwambiri komanso kukana dzimbiri, zomwe zimawathandiza "kumamatira ku nsanamira zawo" m'malo ambiri "ovuta".
Ponena za kukana kutentha kwambiri, ngakhale mutagwira ntchito kwa nthawi yayitali pa 1350 ℃, sipadzakhala kufewa kapena kusintha. Khalidweli limapangitsa kuti likhale "lokondedwa" m'mafakitale a ndege ndi ankhondo, monga momwe amagwiritsidwira ntchito ngati nozzle ya injini za roketi, zingwe za uvuni zotentha kwambiri, ndi zina zotero. Limatha kukhudza mwachindunji malawi otentha kwambiri kapena zitsulo zosungunuka kuti likhale lolimba. Mu njira zopangira kutentha kwambiri monga ma uvuni a mafakitale ndi kuponyedwa kosalekeza kwa zitsulo, zigawo za ceramic za silicon carbide zimathanso kusintha zitsulo zomwe zimawonongeka mosavuta ndi kutentha kwambiri, zomwe zimapangitsa kuti zida zikhale ndi moyo wautali.
Ponena za kukana dzimbiri, zinthu zomangira za silicon carbide zimakhala ndi mphamvu kwambiri pa mankhwala. Kaya ndi asidi, alkali, kapena mpweya ndi zakumwa zosiyanasiyana zowononga, n'zovuta "kuziwononga". Chifukwa chake, m'makampani opanga mankhwala, nthawi zambiri amagwiritsidwa ntchito popanga ziwiya zoyatsira, mapaipi ndi ma valve onyamulira zinthu zowononga; Pankhani yoteteza chilengedwe, kupezeka kwake kumatha kuwonekanso m'zida zochizira madzi otayira okhala ndi asidi ambiri, kuonetsetsa kuti zidazo sizikuwonongeka ndikugwira ntchito bwino.
3、 "Luso" Losiyanasiyana: "Mphunzitsi Wogwira Ntchito" yemwe angathe kukhala wolimba mtima komanso wosinthasintha
Ngati mukuganiza kuti zoumba za silicon carbide ndi "zolimba" komanso "zolimba", ndiye kuti mumazipeputsa kwambiri. Malinga ndi njira zosiyanasiyana zopangira, zimatha kukhala ndi ntchito zosiyanasiyana monga kuyendetsa magetsi, kutchinjiriza magetsi, ndi kuyendetsa magetsi, zomwe zimapangitsa kuti zikhale zinthu zogwirira ntchito zosiyanasiyana.
-Makhalidwe a ma conductivity ndi semiconductor: Mwa kugwiritsa ntchito zinthu zina, silicon carbide ceramics imatha kusintha kuchoka pa ma insulators kukhala ma conductor, komanso kukhala zida za semiconductor. Izi zimailola kuwonetsa luso lake pakugwiritsa ntchito mphamvu zamagetsi, monga kupanga ma module amagetsi a magalimoto atsopano amphamvu ndi zigawo zazikulu za ma traction converters m'ma sitima othamanga kwambiri. Poyerekeza ndi zipangizo zachikhalidwe za silicon, ma silicon carbide semiconductors ali ndi mphamvu zambiri zoyendetsera magetsi komanso kugwiritsa ntchito mphamvu zochepa, zomwe zingapangitse magalimoto atsopano amphamvu kuti azilipiritsa mofulumira komanso kukhala ndi nthawi yayitali, komanso zimapangitsa kuti zida zamagetsi zikhale zochepa komanso zogwira ntchito bwino.
-Kutentha kwabwino kwambiri: Kutentha kwa silicon carbide ceramics kumaposa kwambiri kwa ceramics wamba, ndipo kumafanana ndi kwa zitsulo zina. Izi zimapangitsa kuti ikhale chinthu chabwino kwambiri chotenthetsera kutentha, mwachitsanzo, mu gawo lotenthetsera kutentha la nyali za LED ndi tchipisi zamagetsi, imatha kutulutsa kutentha mwachangu, kuteteza zida kuti zisawonongeke chifukwa cha kutentha kwambiri, ndikuwonjezera moyo wautumiki ndi kukhazikika.
4, Pomaliza: Zoumba za silicon carbide, 'mphamvu yosaoneka yoyendetsera' yokonzanso mafakitale
Kuyambira "yolimba komanso yosawonongeka" mpaka "yosagwira ntchito kwambiri chifukwa cha dzimbiri", kenako mpaka "yogwira ntchito zambiri", zoumba za silicon carbide zasokoneza kumvetsetsa kwa anthu za zoumba zachikhalidwe ndi zinthu zabwino kwambiri, zomwe zakhala zinthu zofunika kwambiri pothandizira kupanga zinthu zapamwamba, mphamvu zatsopano, kusunga mphamvu komanso kuteteza chilengedwe. Sizofala kwambiri ngati chitsulo kapena zopepuka ngati pulasitiki, koma m'mafakitale omwe amafuna "kuthana ndi mavuto", nthawi zonse zimadalira "mphamvu zake zonse" kuti zikhale mphamvu yayikulu pothetsa mavuto.
Ndi kupita patsogolo kosalekeza kwa ukadaulo, mtengo wopanga zinthu za silicon carbide ceramics ukuchepa pang'onopang'ono, ndipo zochitika zogwiritsira ntchito zikukulirakulira nthawi zonse. M'tsogolomu, zida zatsopano zamagetsi zogwira ntchito bwino komanso makina olimba amakampani zitha kukhala zamphamvu kwambiri chifukwa cha kuwonjezera zinthu za silicon carbide ceramics. Mtundu uwu wa "zinthu zamphamvu" zobisika m'makampani ukusintha pang'onopang'ono kupanga ndi moyo wathu.
