Kusintha kwa ntchito ya alumina ufa mumakampani owononga
Omwe adagwirapo ntchito m'mabwalo a abrasive amadziwa kuti ndi mutu wothana ndi zipangizo zolimba kwambiri - zipsera kuchokera ku gudumu lopera, zokopa pa ntchito, ndi kutsika kwa zokolola. Nkhope ya bwana ndi yakuda kuposa pansi pa mphika. Mpaka ufa woyera waaluminiyamu ufaadathamangira mubwalo lankhondo, adakokera makampani owopsa munyengo yatsopano. Lero, tiyeni tikambirane chifukwa chake chinthu ichi chakhala "mpulumutsi wogaya" wamakampani amakono!
1. Waluso: "wankhondo wa hexagonal" mumakampani abrasive
Alumina ufa amabadwa kukhala munthu wolimba yemwe amadya mbale iyi ya mpunga. Zinthu zitatu zolimba kwambiri zimaphwanya anzawo:
Kuuma kwapamwamba: Kuuma kwa Mohs kumayambira pa 9.0, yachiwiri pambuyo pa diamondi. Fakitale yopangira zida ku Guangdong yoyezera: Mukadula chitsulo chothamanga kwambiri, moyo wa mawilo a alumina ogaya ndi kuwirikiza katatu kuposa abrasives wamba. Mbuye wamkulu Huang ananena ndi ndudu m’kamwa mwake kuti: “Ndinkasintha gudumu lopera katatu podula zitsulo za alloy, koma tsopano ndimatha kuchita zonse popanda kupuma!”
Chiyero chodabwitsa: 99.6% α-Al₂O₃ zokhutira, zonyansa zachitsulo zimaponderezedwa mpaka zosakwana 0.01%. Fakitale ya Shanghai Semiconductor inasokonekera: pogwiritsa ntchito ma abrasives okhala ndi chitsulo kuti apukutire, pamwamba pamawoneka ngati ma pockmark patatha miyezi itatu; pogwiritsa ntchito alumina ufa pochiza, sichisintha mtundu ngakhale mumadzi osambira a asidi.
Kukhazikika kwa kutentha kuli ngati galu wokalamba: malo osungunuka 2050 ℃, coefficient yowonjezera kutentha yotsika ngati 4.8×10⁻⁶/℃. Fakitale ya rocket nozzle ku Qingdao imagwiritsa ntchito pogaya ma aloyi otentha kwambiri, ndipo kusinthasintha kwake pansi pa 1500 ℃ chilengedwe kumakhala kosakwana ka 6 m'mimba mwake mwa tsitsi.
Chodabwitsa kwambiri ndi chakuti imatha kusintha mawonekedwe ake nthawi 72 - kuchokera ku tinthu tating'onoting'ono tating'onoting'ono kupita ku nano-level spherical powder, imatha kukhala yozungulira kapena yathyathyathya momwe mukufunira, ndipo idapangidwa mwapadera kuti ichize kusamvera kwamitundu yonse!
2. Zochitika zachisinthiko: "Kuphulika kwamphamvu kwa zida zanyukiliya" m'mabwalo atatu akuluakulu omenyera nkhondo
Msonkhano wa Semiconductor: Maluso opaka utoto wa Nano-level
Kupukuta kwa silicon wafer: Aluminiyamu pang'onopang'ono wa micropowder amasambira pamwamba pa chowotcha cha silicon ngati skating, ndipo kukanda kumatsika ndi 70% poyenda motsetsereka m'malo mogudubuza mwachikhalidwe. Mbuye wa SMIC anafuula kuti: “Ntchito imeneyi ndi yovuta kuposa kupeta nsalu!”
Silicon carbide chip: Nano-alumina kupukuta kwamadzimadzi kumabowola mumpata wa chip, ndipo kutentha kwapang'onopang'ono kumatheka chifukwa cha kuchuluka kwa tunnel, ndipo zokolola zimakwera mpaka 99.98%. Katswiri wa ntchitoyo anasisita chithunzi cha maikulosikopu a elekitironi n’kudzitama kuti: “Kulondola kumeneku n’kwapamwamba kwambiri moti ngakhale udzudzu utaimapo umatha kugawanika!”
Sapphire substrate: Submicron alumina imapukuta gawo lapansi la LED mpaka Ra<0.3nm, lomwe ndi losalala kuposa kalilole. Bwana wa Dongguan Optoelectronics Factory ananena mosangalala kuti: "Tsopano tikupanga magalasi a iPhone, ndipo oyang'anira Apple sakupeza cholakwika nawo!"
Msonkhano wamagalimoto: kupha mtengo pa intaneti
Zamlengalenga: akatswiri ovuta kwambiri
Turbine blade mortise ndi tenon processing:Chiguduli cha aluminiyamuimagwira ntchito pa alloy-based alloy, ndipo imatha kupirira maola 100 osataya ufa pa liwiro la 2200 rpm. Dalaivala woyeserera Lao Li anayang'ana pa sewero loyang'anira ndikufuula kuti: "Ndi kukana uku, ngakhale Musk amayenera kudutsa ndudu!"
Rocket nozzle mkati mwakhoma kupukuta: Nano- TACHIMATA aluminiyamu ufa amachepetsa roughness kuti Ra0.01μm, ndi mafuta mphamvu bwino ndi 8%. Mainjiniya wamkulu ananena ndi maso ofiira kuti: “Chinthu chimodzi chokhachi chingapulumutse matani atatu amafuta chaka chilichonse!”
3. Kulimbana ndi zopanga zapakhomo: kuchokera ku "khosi lokhazikika" mpaka "kulimbana ndi mkono"
Abrasives aluminiyamu apakhomo ankakhala "nkhani yomvetsa chisoni" - kukana kuvala kosauka, magulu osakhazikika, nano powder agglomeration ngati supu ya pimple, ndipo msika wapamwamba unkayendetsedwa ndi makampani a ku America ndi Japan13. Koma funde la semiconductor localization linakakamiza Jedi counterattack:
Chiyero kuukira: Fakitale ku Luoyang wapanga arc ng'anjo wanzeru kulamulira kutentha, ndi α gawo kutembenuka kwafika 99,95%, ndi chiyero ndi wofanana Japan Showa Denko .
Metaphysics kukula kwa tinthu ting'onoting'ono: Makampani a Zhejiang amagwiritsa ntchito magulu a turbine a AI kuwongolera kugawa kwa tinthu mkati mwa ± 0.1μm. Makasitomala aku Korea anagwetsa nsagwada poyang'ana katunduyo: "Deta iyi ndi yolondola kuposa chowunikira!"
Kubadwanso kwa zinyalala: Shandong maziko amaphwanya ndikuyeretsanso zinyalalamagudumu akupera, ndipo chiŵerengero cha admixture chimachepetsedwa kufika 30%, ndipo mtengowo umachepetsedwa ndi 40%. Woyang’anira msonkhanowo, a Lao Zhou, anaseka ndi kudzudzula kuti: “Zinyalala zimene kale zinkatayidwa mwangozi tsopano ndi zamtengo wapatali kuposa zipangizo zatsopano!”
4.Nkhondo yamtsogolo: zochitika zazikulu zitatu ndizokhazikika
Nano-level control: Hefei laboratory yabwera ndi ukadaulo wakuda - ukadaulo wa atomiki wosanjikiza kuti aike "zida" pazida zazing'ono ndikuthana ndi vuto la agglomeration. Wofufuzayo adanyamula chitsanzocho ndikudzitama kuti: "Tsopano kupukuta kwa chip ndikosavuta kuposa kupaka phula!"
Green Revolution: Chomera cha Chongqing chimagwiritsa ntchito njira yobwezeretsa zinyalala kuti achepetse kutaya kwa matani 300 a zinyalala zoopsa chaka chilichonse. Anthu a m’bungwe loteteza zachilengedwe anabwera kudzacheza nati: “Mudzachotsa malo osungira zimbudzi!”
Zida zogaya zanzeru: Fakitale ku Zhengzhou idayika cholumikizira pa gudumu lopera kuti chisinthe magawo akupera munthawi yeniyeni. Xiao Liu, katswiri wobadwa m'ma 1990, adalemba pa kiyibodi ndikudzitama kuti: "Tsopano kusintha magawo ndikosavuta kuposa kusewera masewera, ndipo zokolola zafika 99.8%!"
