Chinsinsi cha ufa wobiriwira wa silicon carbide kuti zinthu zopangidwa ndi zinthu zophatikizika zigwire bwino ntchito

Anthu amene adagwira ntchito yopangira zinthu zosiyanasiyana amadziwa kuti n'kovuta kuphatikiza ubwino wa zinthu zosiyanasiyana kukhala mbale yabwino kuposa kuyanjanitsa ubale wa apongozi ndi mpongozi wawo. Koma kuyambira pomwe zidayamba kugwiritsidwa ntchitoufa wobiriwira wa silicon carbide, "zokometsera zamatsenga", bwalo la zinthu zophatikizika layatsa mwachindunji "njira yotsegulira". Lero, tiyeni tivumbulutse chophimba chachinsinsi ichi ndikuwona momwe mulu uwu wa ufa wobiriwira ungapangire akatswiri odzikuza monga ulusi wa kaboni ndi zoumba zadothi kukhala omvera.

1. “Msilikali waluso”

Ufa wobiriwira wa silicon carbide unabadwa kuti ukhale "ufa wa maloto" wa zinthu zopangidwa ndi zinthu zopangidwa ndi zinthu zosiyanasiyana. Kuuma kwa Mohs ndi 9.5, komwe ndi mpweya woipa kuposa diamondi. Fakitale yopangira mabuleki ku Guangdong yayerekeza. Zinthu zopangidwa ndi zinthu ...

Mphamvu ya kutentha ndi yodabwitsa kwambiri. Shandong Research Institute yayesa deta ndipo yapeza kuti mphamvu ya kutentha ya zinthu zopangidwa ndi aluminiyamu zokhala ndi 15% silicon carbide yobiriwira inakwera kufika pa 220W/(m·K), yomwe ndi yamphamvu ndi 30% kuposa aluminiyamu yeniyeni. Katswiri Xiao Liu anayang'ana chithunzi cha kutentha ndipo anati: "Njira yochotsera kutentha iyi ikufanana ndi kukhazikitsa makina ozizira a madzi pa CPU!"

Kukhazikika kwa mankhwala ndi kwapadera kwambiri. Poyesa zinthu zomangira za paipi ya mankhwala ku Ningbo, zinthu zobiriwira za silicon carbide zinanyowa mu sulfuric acid yochuluka kwa theka la chaka, ndipo kuchepa kwa thupi kunali kochepera 0.3%. Woyang'anira khalidwe Lao Wang ananyamula chitsanzocho ndikudzitamandira kuti: "Kukana dzimbiri kumeneku, ngakhale ng'anjo ya alchemy ya Taishang Laojun iyenera kuletsa ndudu!"

2. "Nthawi yamatsenga" ya njira yopangira zinthu zosiyanasiyana

Ukadaulo wofalitsa zinthu tsopano ndi wabwino kwambiri. Kampani ina ku Jiangsu yapanga njira yosakaniza "ultrasound + ball milling", yomwe imafalitsa ufa wa micropowder mofanana kuposa ngale zomwe zili mu tiyi wa mkaka. Master Lao Li adakweza chithunzi cha maikulosikopu ya ma elekitironi ndikudzitamandira kuti: "Taonani kuchuluka kwa kufalitsa kumeneku, nyerere zidzasochera ngati zitakwera mmwamba!"

Ukadaulo wakuda wophatikiza mawonekedwe ndi woopsa kwambiri. Cholumikizira cha nano-coupling chomwe chinapangidwa ndi labotale ku Shanghai chawonjezera mphamvu yolumikizirana pakati pa ufa wa micropowder ndi matrix kufika pa 150MPa. Mtsogoleri wa polojekitiyi anakweza magalasi ake nati: “Nthawi yomaliza yomwe tinachita mayeso a shear, chogwiriracho chinali chosokonekera, koma zinthu zophatikizika sizinasinthe!”

3. "Onetsani zochitika" za mayeso enieni a nkhondo

Makampani opanga ndege akhala akupenga kwa nthawi yayitali. Masamba a turbine a fakitale ina ya injini za ndege ku Chengdu amagwiritsa ntchitokabide wobiriwira wa silikonikuti alimbikitse zinthu zopangidwa ndi ceramic, ndipo kutentha kwake kumafika pa 1600℃. Woyendetsa mayeso Lao Zhang anayang'ana pa dashboard ndipo anagwetsa madzi: "Ndi magwiridwe antchito awa, injini za jet ziyenera kuyimbira abambo!"

Chitseko cha batire cha magalimoto atsopano amphamvu n'chosangalatsa kwambiri. Chitseko cha carbon fiber cha wopanga ku Ningde chili ndi mphamvu yowirikiza kasanu ndi kawiri kuposa ya chitsulo pambuyo poti chasakanizidwa ndi silicon carbide yobiriwira. Pa nthawi yoyesera ngozi, mainjiniya wa chitetezo Lao Li anagogoda pakhomo la galimotoyo naseka kuti: "Tsopano thupi la galimotoyi lili ngati kuvala ma vesti atatu osalowa zipolopolo!"

Malo otenthetsera magetsi a 5G base station ndi ovuta kwambiri. Radiator yopangidwa ndi aluminiyamu ya wopanga ku Hangzhou ili ndi mphamvu yowonjezera kutentha yomwe imayendetsedwa kufika pa 4.8×10⁻⁶/℃. Woyang'anira zaukadaulo adatchula deta yoyesera kutentha ndipo adadzitama kuti: "Itha kusinthidwa kuchokera pa -50℃ mpaka 200℃, ndipo kusintha kwa kukula kwake ndi kwakukulu kuposa Virgo!"

4, "Kusunga nthawi yayitali" mu akaunti ya ndalama

Musayang'ane mtengo wapamwamba wa mayunitsiufa wobiriwira wa silicon carbide micropowder, zimakhala zopindulitsa kwambiri mukawerengera akaunti yonse. Fakitale yamakina ku Chongqing yachita kafukufuku wa ndalama: ngakhale mtengo wa zipangizo zopangira wakwera ndi 25%, moyo wa zinthu wawonjezeka kanayi, ndipo ndalama zosamalira zomwe zasungidwa m'zaka zitatu ndizokwanira kumanga malo atsopano ogwirira ntchito. Mayi wazachuma adadina chowerengera ndikuseka kuti: "Bizinesi iyi ndi yopindulitsa kwambiri kuposa ngongole!"

Kukwera kwa magwiridwe antchito opanga zinthu kumakhala kosangalatsa kwambiri mwachinsinsi. Malinga ndi muyeso weniweni wa mzere wopanga wokha ku Tianjin, nthawi yokonza zinthu zopangidwa ndi zinthu zophatikizika yafupikitsidwa ndi 40%. Wotsogolera ntchito yokonza zinthu anayang'ana pazenera lalikulu ndikumenya miyendo yake: "Tsopano mphamvu yopangira zinthu ili ngati kukwera roketi, ndipo makasitomala sakuchita mantha akamapempha maoda!"

Ufa wobiriwira wa silicon carbide wa masiku ano sulinso chinthu chodziwika bwino mu labotale. Kuyambira pa zombo zouluka mlengalenga mpaka magalimoto atsopano amphamvu omwe akuyenda pansi, kuyambira pa tchipisi ta mafoni a m'manja tofanana ndi kanjedza mpaka masamba a turbine ya mphepo otalika mamita 100, uli paliponse. Asilikali akale mumakampaniwa akuti chinthuchi chapanga dzenje padenga la magwiridwe antchito a zinthu zopangidwa ndi zinthu zosiyanasiyana. M'malingaliro mwanga, izi sizongosintha zinthu zokha, koma "chinthu chothandiza" m'makampani amakono. Ngati izi zipitirira, ndizotheka kuti tsiku lina matabwa athu odulira adzayenera kugwiritsa ntchito ukadaulo wakuda uwu - pambuyo pake, ndani sakufuna kuti ziwiya zawo zakukhitchini zikhale pamlingo womwewo ngati zipangizo zam'mlengalenga?
