Mu dziko la mafakitale opanga zinthu, nthawi zonse pamakhala ziwalo zina zapadera zomwe zimapweteka mainjiniya - zitha kukhala mapaipi opindika mu chipangizo cholondola kapena zomangamanga zothandizira zokhala ndi mipata yovuta mu zida zotentha kwambiri. Zigawozi, zomwe zimadziwika kuti "zigawo zachilendo," nthawi zambiri zimakhala zovuta kupanga kuchokera ku zipangizo wamba chifukwa cha mawonekedwe awo apadera komanso malo ogwirira ntchito ovuta. Masiku ano, silicon carbide, chinthu chomwe chimawoneka ngati chosafunika kwenikweni, chikusintha chilichonse mwakachetechete.
Ubwino weniweni wa zinthuzo
Kumvetsa chifukwa chakekabide ya silikoniPopeza imatha kusintha ziwalo zosakhazikika, choyamba tiyenera kuyang'ana "kapangidwe kake". Chida ichi mwachibadwa chimakhala ndi "majini abwino kwambiri" ofunikira popanga mafakitale: kuuma kwake ndi kwachiwiri kuposa diamondi, koma kumatha kupirira kusintha kwakukulu kwa kutentha monga chitsulo; Poyang'anizana ndi dzimbiri la ma acid ndi alkali amphamvu, sichisuntha; Ngakhale kutentha kwambiri pafupi ndi dzuwa, chimatha kukhalabe ndi mawonekedwe okhazikika.
Kuphatikiza kwa makhalidwe kumeneku kunalola kuti silicon carbide ipambane pamzere woyambira kuyambira pachiyambi. Tangoganizirani kuti ngakhale zipangizo zina zikuvutikabe kudziwa ngati zingapangidwe kukhala mawonekedwe awa, silicon carbide ikuganizira kale momwe ingapangire kukhala yabwinoko. Mphamvu yake yayikulu komanso kukhazikika kwake zimathandiza opanga kuti apewe kusintha kapangidwe kake koyambirira kuti kagwirizane ndi zinthu zakuthupi.
'Zamatsenga' zosinthasintha komanso zosinthasintha
Kukhala ndi zipangizo zabwino zokha sikokwanira. Kuti musinthe silicon carbide kukhala ziwalo zosiyanasiyana zachilendo, pakufunikanso "matsenga apadera opangira mawonekedwe". Masiku ano mainjiniya aphunzira njira zosiyanasiyana zopangira silicon carbide kukhala "yomvera":
Ukadaulo wopondereza zinthu mozizira uli ngati kuyika "chovala cholimba" chapadera pa ufa wa silicon carbide. Pakapanikizika kwambiri, ufawo ukhoza kumamatira mofanana ku chilichonse cha nkhungu, ngakhale mabowo ovuta komanso mapangidwe osavuta amatha kubwerezedwa molondola. Ukadaulo wa laser wotsogozedwa ndi madzi uli ngati "mpeni wofewa wochita opaleshoni", pogwiritsa ntchito madzi othamanga kwambiri kutsogolera laser ndikusema nyumba zosiyanasiyana zovuta pa silicon carbide yolimba, zomwe sizingayambitse ming'alu ya zinthu ndipo zimatha kuonetsetsa kuti pamwamba pake pali posalala.
Kupita patsogolo kwa ukadaulo kumeneku kwatulutsa silicon carbide ku chizindikiro cha zoumba zachikhalidwe monga "zolimba, zolimba, komanso zovuta kukonza". Monga momwe zimakhalira ndi dongo la rabara, ukadaulo wamakono umalola ufa wa silicon carbide kupanga thupi lomwe lili pafupi ndi mawonekedwe ake omaliza, kenako nkudutsa kutentha kwambiri kuti likhale chinthu chomalizidwa bwino, zomwe zimachepetsa kwambiri zovuta zokonza pambuyo pake.
Udindo Wodalirika M'malo Ovuta Kwambiri
N’chifukwa chiyani tiyenera kuyesetsa kwambiri kugwiritsa ntchito silicon carbide popanga zinthu zosakhazikika? Chifukwa nthawi zambiri, zinthu zopangidwa mwapaderazi zimagwira ntchito m’malo ovuta kwambiri.
Mu ketulo yamphamvu ya asidi yomwe imapangidwa mu fakitale ya mankhwala, payipi yooneka ngati silicon carbide imatha kupirira dzimbiri; Mu malo otentha kwambiri a injini za ndege, mabulaketi ooneka ngati silicon carbide amatha kupirira mayeso a madigiri zikwizikwi; Mu zida zolondola zopangira semiconductor, zida zooneka ngati silicon carbide zimatha kusunga kulondola kokhazikika. Muzochitika izi, mawonekedwe apaderawa sakutanthauza kuti aziwoneka bwino, koma kuti akwaniritse ntchito zinazake - mwina ndi kupangitsa kuti madzi aziyenda bwino, kapena kungakhale kutulutsa kutentha mofanana.
Kupadera kwa silicon carbide kuli m'kuthekera kwake kukwaniritsa zofunikira pakupanga nyumba zosakhazikika komanso kugwira ntchito modalirika m'malo ovuta kwambiri kwa nthawi yayitali. Kuphatikiza kwa kulimba ndi kusinthasintha kumeneku kwapangitsa kuti ikhale chinthu chomwe chimakonda kwambiri m'mafakitale ambiri.
Tsogolo la kupanga zinthu mwamakonda
Ndi kupita patsogolo kwa ukadaulo wopanga zinthu, luso losintha zinthu kukhala mawonekedwe a silicon carbide likukula nthawi zonse. Kuyambira pa ma microstructures ochepa mpaka zigawo zazikulu mamita angapo kutalika, kuyambira pa kupindika kosavuta mpaka polyhedra yovuta, silicon carbide ikuphwanya kumvetsetsa kwa anthu pazinthu zadothi.
Kwa mabizinesi, izi zikutanthauza mwayi watsopano - osafunikiranso kuchepetsa malingaliro opanga zida wamba, komanso kukhala ndi mwayi wokonza njira zabwino kwambiri kutengera zosowa zenizeni. Pa gawo lonse la mafakitale, kutchuka kwa zida zooneka ngati silicon carbide kukuyendetsa chitukuko cha zida kuti zikhale zogwira mtima kwambiri, zolimba, komanso zolondola.
Zipangizo zamatsenga izi, ndi "mphamvu zake zolimba" ndi "luso lake laukadaulo", zimasintha mapangidwe osakhazikika omwe kale anali pachithunzichi kukhala mphamvu zogwira ntchito zomwe zimayendetsa patsogolo mafakitale.
