Kulumikizana kopanda malire pakati pa white corundum ndi teknoloji yamtsogolo
Aliyense mu bwalo laukadaulo amadziwa kuti zida zatsopano ndi ndalama zolimba. Ndani akanaganiza zimenezowhite corundum, yomwe imawoneka ngati shuga woyera, idzakhala "wolimbikitsa wosaoneka" wa kusintha kwa sayansi yamtsogolo. Kuyambira tchipisi tamafoni kupita ku Mars rover, kuchokera pamakompyuta a quantum kupita ku zida zoyendetsedwa ndi zida zanyukiliya, zitha kupezeka paliponse. Lero, tiyeni tivule chovala chaukadaulo ichi ndikuwona momwe msirikali wakale wamakampaniyu amachitira zinthu zazikulu mwakachetechete.
1. “Jini yaukadaulo” yamphatso
Zinthu zolimba za corundum zoyera zimangopangidwira ukadaulo wamtsogolo. Ndi kuuma kwa Mohs kwa 9.0, ndi mpweya woipa kuposa diamondi. Fakitale yopanga makina ojambula zithunzi ku Shanghai yachita kuyesa kofananira. Kukula kwamphamvu kwa njanji yopukutidwa ndi corundum yoyera kumatha kufika ku Ra0.008μm. Katswiri Xiao Li adagwira chogwiriracho ndikugunditsa milomo yake: "Molondola uku, udzudzu ungathyole fupa ngati utayimapo!"
Kukhazikika kwa kutentha kumakhala koipitsitsa kwambiri. Zambiri zochokera ku labotale yoyang'anira nyukiliya ku Qingdao zidawonetsa kuti zoumba zoyera za corundum zimapirira kutentha kwambiri kwa 2000 ℃ kwa maola 100, ndipo kusintha kwake kunali kosakwana 0.01%. Wofufuza wina dzina lake Lao Wang anasisita m’chipindacho n’kunena kuti: “Zinthu zimenezi zimatha kuima padzuwa kwa masiku awiri!”
2. "Osewera Obisika" mu Semiconductor Field
Pankhondo ya nano-scale yopanga chip, corundum yoyera yakhala "monki akusesa". Fakitale yopyapyala ku Taizhou idagwiritsa ntchito ufa wa 0.1μm woyera wa corundum podula zowotcha za silicon, ndipo kugwa kwa m'mphepete kunachepetsedwa kukhala 0.2 ‰. Master Lao Chen adayang'ana maikulosikopu ndikuseka: "Tsopano kudula zowotcha ndizothandiza kwambiri kuposa kudula tofu, ndipo zokolola zafika 99.98% mwachindunji!"
Kupukuta kwa mandala a makina a lithography ndikowona kwambiri. Zambiri zochokera ku labotale ku Beijing zikugwetsa nsagwada: mandala amapangidwa ndi madzi oyera a corundum nano-polishing, ndipo kutsetsereka kwapansi kumafika pa λ/50 wavelength. Mkulu wa zaumisiri a Lao Liu adalankhula ndi manja kuti: "Kulondola uku ndikufanana ndi kukhazikitsa galasi la ndege panyanja ya Pacific!"
3. "Compression King" mu Aerospace Industry
White corundum ili ndi mawu omaliza pakukonza magawo a Mars rover. Fakitale ina yazamlengalenga ku Xi'an imagwiritsa ntchito mawilo oyera akupera a corundum pogaya mabulaketi a titaniyamu, ndipo kupsinjika kotsalira kumayendetsedwa mkati mwa ± 5MPa. Chief Engineer Lao Zhang adati ndi ndudu mkamwa mwake: "Ndi mlingo uwu, Musk amayenera kudutsa ndudu kuti afunse malangizo!"
Ma injini azamlengalenga afika patali. Zambiri za kampani ina ya injini za ndege ku Chengdu ndizochititsa chidwi: masamba amtundu wa corundum ceramic-based composite, omwe amatha kutentha mpaka 1600 ℃. Woyendetsa mayeso a Lao Li anayang'ana pa bolodi ndikugwetsa m'maso: "Ndikuchita izi, ma injini a jet ayenera kuyimbira abambo!"
4. "Chitsimikizo cha Kupirira" mu New Energy Track
White corundum ndiyabwino kwambiri kudula zidutswa za batri yamphamvu. Fakitale ya batri ku Ningde yoyezera: kugwiritsa ntchito waya wamchenga woyera wa corundum kudula zokutira za graphene, kutalika kwa burr kumayendetsedwa mpaka pansi pa 0.5μm. Woyang'anira malo ogwirira ntchito a Lao Zhou adasisita batriyo ndikunena mosangalala kuti: "Kuchulukana kwamphamvu kwa batire iyi ndikwabwino kuposa ya Tesla!"
5. "Black Technology Preview" ya Future Battlefield
White corundum ndi yabwino kuziziritsa makompyuta a quantum. Laborator ku Hefei yapanga filimu ya nano-scale white corundum thermal conductivity yokhala ndi matenthedwe a 400W/m·K. Wofufuza wina dzina lake Lao Ma anadzitama kuti: “Tsopano kutentha kwa ma quantum bits nkwachangu kuposa kuthira chigamba cha malungo!”
Khoma loyamba la kuphatikizika kwa nyukiliya ndi mphamvu yolimba kwambiri. Ceramic yopangidwa ndi white corundum ya bungwe lofufuza ku Mianyang ili ndi nyutroni yowonongeka yomwe imakhala yokwera ka 6 kuposa ya zipangizo zamakono. Chief Engineer Lao Zhao adaloza ku rectoryo nati: "Zinthu izi zikhala zokhazikika mpaka makina opangira mabizinesi apangidwe!"
