Unxibelelwano olungenasiphelo phakathi kwe-corundum emhlophe kunye neteknoloji yexesha elizayo
Wonke umntu kwisangqa setekhnoloji uyazi ukuba izinto ezintsha ziyimali enzima. Ngubani owayenokucinga okocorundum emhlophe, ebonakala ngathi iswekile emhlophe, iya kuba "ngumgqugquzeli ongabonakaliyo" wenguqu yeteknoloji yexesha elizayo. Ukusuka kwiichips zefowuni eziphathwayo ukuya kwiindawo ze-Mars rover, ukusuka kwiikhompyuter ze-quantum ukuya kwizixhobo ezilawulwayo zenyukliya ze-fusion, inokufumaneka kuyo yonke indawo. Namhlanje, masikhulule lo maleko wedyasi yetekhnoloji kwaye sibone ukuba lo makhwekhwetha kwezoshishino azenza njani izinto ezinkulu ngokuzolileyo.
1. “Umfuzo weteknoloji” onesiphiwo
Iimpawu eziqinileyo ze-corundum ezimhlophe zilungelelaniswa nje ngeteknoloji yexesha elizayo. Ngobunzima be-Mohs be-9.0, kukuphefumla okubi ngakumbi kunedayimane. Umzi-mveliso womatshini wokufotokopa eShanghai wenze uvavanyo lokuthelekisa. Uburhabaxa bomphezulu wesikhokelo sikaloliwe ogudisiweyo ngecorundum emhlophe unokufikelela kwiRa0.008μm. Igcisa lika-Xiao Li libambe icwecwe laze labetha imilebe yalo: “Ngokuchaneka ngolu hlobo, ingcongconi ibiya kwaphula ithambo ukuba imi kuyo!”
Ukuzinza kwe-thermal kuyingozi ngakumbi. Idatha esuka kwilabhoratri yokudibanisa inyukliya elawulwayo eQingdao ibonise ukuba iiseramics ezisekwe kwi-corundum emhlophe zimelana nobushushu obuphezulu be-2000 ℃ kwiiyure ze-100, kwaye utshintsho lobungakanani lwalungaphantsi kwe-0.01%. Umphengululi uLao Wang wampampatha kwigumbi lokufunxa waza wathi: “Le nto inokuma phezu kwelanga kangangeentsuku ezimbini!”
2. "IiNtshatsheli ezifihlakeleyo" kwi-Semiconductor Field
Kwidabi le-nano-scale yokwenziwa kwe-chip, i-corundum emhlophe kudala ibe "yimonki etshayelayo". Umzi-mveliso we-wafer e-Taizhou wasebenzisa i-0.1μm emhlophe ye-corundum micro-powder ukusika ama-wafers e-silicon, kwaye izinga lokuwa komphetho liye lancitshiswa laya kwi-0.2‰. U-Master Lao Chen wajonga kwi-microscope waza wahleka: "Ngoku ii-wafers zokusika zisebenza ngakumbi kunokusika i-tofu, kwaye izinga lokuvunwa ngokuthe ngqo ukuya kuma-99.98%!"
Ukukhazimliswa kwelensi yomatshini welithography kuyinyani ngakumbi. Idatha evela kwi-laboratory yaseBeijing i-jaw-dropping: i-lens iphathwa nge-white corundum nano-polishing liquid, kunye ne-flatness yomhlaba ukuya kwi-λ / 50 wavelength. UMlawuli wezobuGcisa uLao Liu wenze ngezandla wathi: "Oku kuchanekileyo kufana nokufaka isipili senqwelomoya kuLwandlekazi lwePasifiki!"
3. "I-Compression King" kwi-Aerospace Industry
I-White corundum inelizwi lokugqibela ekusetyenzweni kweengxenye ze-Mars rover. Umzi-mveliso othile wesixhobo se-aerospace e-Xi'an usebenzisa amavili okusila amhlophe e-corundum ukucola izibiyeli ze-titanium alloy, kwaye intsalela yoxinzelelo lomphezulu ilawulwa ukuya kuthi ga kwi-±5MPa. Unjineli oyiNtloko uLao Zhang uthe ephethe icuba emlonyeni wakhe: “Ngale nqanaba, uMusk kufuneka adlulise umdiza ukuze acele iingcebiso!
Amagqabi enjini ye-aerospace afikelele kubude obutsha. Idatha yenkampani ethile ye-injini ye-aviation e-Chengdu itsala amehlo: iiblade ze-ceramic ezimhlophe ze-corundum ezisekwe kwi-ceramic, ezinokumelana nobushushu ukuya kwi-1600℃. Umqhubi ovavanyayo uLao Li wajonga kwideshibhodi waza wathi: “Ngalo msebenzi, iinjini zejethi kufuneka zibize utata!”
4. "Isiqinisekiso sokunyamezela" kwiNdlela entsha yaMandla
I-corundum emhlophe ilungile kakhulu ekusikeni iziqwenga zeepali zebhetri. Umzi-mveliso webhetri e-Ningde ulinganisa: usebenzisa ucingo lwesanti ye-corundum emhlophe ukusika i-graphene yokwambathisa, ukuphakama kwe-burr kulawulwa ukuya ngaphantsi kwe-0.5μm. Umlawuli weworkshop uLao Zhou wambambazela isisele sebhetri wathi ngovuyo: "Amandla ale bhetri angcono kunekaTesla!"
5. "I-Black Technology Preview" ye-Battlefield yekamva
I-White corundum ilungile ekupholiseni iikhompyuter ze-quantum. Ilabhoratri e-Hefei iphuhlise ifilimu ye-nano-scale emhlophe ye-corundum thermal conductive ene-thermal conductivity ye-400W/m·K. Umphandi uLao Ma waqhayisa ngelithi: “Ngoku ukutshatyalaliswa kobushushu kwiisuntswana zequantum kukhawuleza kunokufaka indawo yomkhuhlane!”
Isixhobo sokuqala sodonga lokudibanisa inyukliya ngamandla anzima ngakumbi. I-ceramic edibeneyo ye-corundum ye-ceramic yeziko lophando e-Mianyang inomda womonakalo we-neutron irradiation ephindwe ngamaxesha angama-6 ngaphezu kwezinto zemveli. Unjineli oyiNtloko uLao Zhao walatha kwi-reactor kwaye wathi: "Esi sixhobo ngokuqinisekileyo siza kuzinza de i-reactor yorhwebo ifakwe kwimveliso!"
