'Wankhondo wa Daimondi' mu Mapaipi Amafakitale: Nchifukwa Chiyani Mapaipi a Silicon Carbide Amaonekera Kwambiri?

M'mafakitale okhudza mankhwala, mphamvu, ndi kuteteza chilengedwe, mapaipi ali ngati "mitsempha yamagazi" ya zida, zomwe nthawi zonse zimanyamula zinthu zosiyanasiyana zofunika. Koma mikhalidwe ina yogwirira ntchito imatha kutchedwa "purigatoriyo": malo otentha kwambiri amatha kupangitsa zitsulo kukhala zofewa, ma asidi amphamvu ndi ma alkali amatha kuwononga makoma a mapaipi, ndipo madzi okhala ndi tinthu tating'onoting'ono amapitirira kuwonongeka ndi kuwonongeka. Pakadali pano, mapaipi achikhalidwe nthawi zambiri amavutika, pomwemapaipi a silicon carbideakuthetsa mavutowa ndi chibadwa chawo chosatha.
Born Strong: Chinsinsi Chogwira Ntchito cha Silicon Carbide
Mphamvu ya zoumba za silicon carbide ili mu "majini ake" - zoumba za silicon carbide zimadziwika kuti "diamondi yakuda" ya gawo la mafakitale, ndi zabwino zitatu zazikulu.
Kulimba kwake n'kodabwitsa kwambiri, kwachiwiri kuposa diamondi ndipo kuwirikiza kasanu kuposa chitsulo wamba. Poyang'anizana ndi kukokoloka kwamadzimadzi komwe kuli ndi tinthu tolimba, kuli ngati kuvala "chida cholimba" chomwe sichimavalidwa mosavuta ndipo chimakhala ndi moyo wautali kuposa mapaipi achitsulo. M'malo otentha kwambiri, ndi 'master bata', ngakhale kutentha kwa madigiri Celsius zikwizikwi, kapangidwe kake kamakhala kolimba, mosiyana ndi chitsulo chosapanga dzimbiri chomwe chimagwa mwadzidzidzi mphamvu yake ikakwera pang'ono. Ndipo imatha kupirira kusintha kwakukulu kwa kutentha, ndipo sidzasweka ngakhale itakumana ndi zinthu zotentha kwambiri m'nyengo yozizira.
Chofunika kwambiri ndi "luso lake loletsa dzimbiri", lomwe lingatchedwe kuti "chitetezo" cha asidi. Kaya ndi ma asidi amphamvu monga sulfuric acid yokhazikika ndi hydrofluoric acid, kuchuluka kwa sodium hydroxide ndi maziko olimba, kapena ngakhale mchere wothira ndi chitsulo chosungunuka, n'kovuta kuwononga khoma lake la mapaipi. Izi zimathetsa vuto lalikulu la dzimbiri ndi kutuluka kwa mapaipi m'mafakitale ambiri.
Poyerekeza ndi miyambo: nchifukwa chiyani ndi yodalirika kwambiri?
Poyerekeza ndi mapaipi achikhalidwe, ubwino wa mapaipi a silicon carbide unganenedwe kuti ndi "kuchepetsa kukula".
Mapaipi achitsulo amatha kufewa kutentha kwambiri ndipo amatha kupsa ndi electrochemical akakumana ndi asidi ndi alkali. Zoipa zimatha kufalikira ngakhale panthawi yonyamula zinthu zolondola, zomwe zimakhudza ubwino wawo. Ngakhale mapaipi apulasitiki opangidwa ndiukadaulo sagonjetsedwa ndi dzimbiri, malire awo oletsa kutentha ndi otsika kwambiri, nthawi zambiri osakwana 200 ℃, ndipo amathanso kukalamba komanso kusweka. Mapaipi wamba a ceramic sagonjetsedwa ndi kutentha kwambiri komanso kuwonongeka, koma ndi ofooka kwambiri ndipo amatha kusweka ngakhale kutentha kusinthasintha pang'ono.

Ndipo mapaipi a silicon carbide amapewa bwino zofooka izi, ndi mphamvu zitatu zazikulu za kuuma, kukana kutentha, ndi kukana dzimbiri zomwe zimagwiritsidwa ntchito mokwanira, zomwe zimakwaniritsa bwino zofunikira zazikulu zamakampani amakono kuti mapaipi akhale "atali, okhazikika, komanso osamalidwa bwino".
Kuyamba bizinesi: Kupezeka kwake kungapezeke kulikonse
Masiku ano, mapaipi a silicon carbide akhala "muyezo" pazochitika zambiri zogwirira ntchito kwambiri. Mu makampani opanga mankhwala, ali ndi udindo wonyamula ma asidi ndi alkali osiyanasiyana popanda kusinthidwa pafupipafupi; Mu dongosolo la desulfurization ndi denitrification la mafakitale amphamvu, imatha kupirira kutentha kwambiri komanso chinyezi chambiri, ndipo nthawi yake yogwirira ntchito imatha kupitirira zaka 10.
Mu mafakitale a semiconductor, kuyera kwake kwakukulu kumatsimikizira kuti mpweya woipa kwambiri sunayendetsedwe, zomwe zimapangitsa kuti ikhale "muyezo wagolide" wopanga ma chip; Mumakampani opanga zitsulo, imatha kunyamula tinthu tachitsulo totentha kwambiri ndi ufa wa ore popanda mantha a kuwonongeka ndi kuwonongeka. Ngakhale mumakampani opanga ndege, njira zoyendera mpweya zotentha kwambiri za injini za rocket sizingathe kuchita popanda thandizo lawo.
Ndi kupita patsogolo kwa ukadaulo wapakhomo, mtengo wa mapaipi a silicon carbide watsika kwambiri, ndipo amathanso kusinthidwa kuti agwirizane ndi minda yomwe ikubwera monga mphamvu ya hydrogen ndi ndege kudzera mu njira zopangira mankhwala. 'Warrior' uyu mu mapaipi a mafakitale akugwiritsa ntchito mphamvu zake kuteteza magwiridwe antchito okhazikika a mafakitale osiyanasiyana.
