Haɗin da ba shi da iyaka tsakanin farin corundum da fasaha na gaba
Kowane mutum a cikin da'irar fasaha ya san cewa sababbin kayan kuɗi ne mai wuyar gaske. Wa zai yi tunanin hakafarin corundum, wanda yayi kama da farin sukari, zai zama "mai gabatarwa marar ganuwa" na juyin juya halin fasaha na gaba. Daga guntuwar wayar hannu zuwa sassan Mars rover, daga kwamfutoci masu yawa zuwa na'urori masu sarrafa makaman nukiliya, ana iya samun su a ko'ina. A yau, bari mu cire wannan rigar fasaha mu ga yadda wannan tsohon sojan masana'antu ke yin manyan abubuwa cikin nutsuwa.
Abubuwan da ke da ƙarfi na farin corundum an yi su ne kawai don fasaha na gaba. Tare da taurin Mohs na 9.0, numfashi ne kawai mafi muni fiye da lu'u-lu'u. Masana'antar na'ura mai daukar hoto a Shanghai ta gudanar da gwajin kwatancen. Ƙunƙarar saman filin jirgin jagora wanda aka goge da farin corundum zai iya kaiwa Ra0.008μm. Masanin fasaha Xiao Li ya rike kayan aikin ya bugi lebbansa: "Da wannan madaidaicin sauro zai karya kashi idan ya tsaya a kai!"
Ƙarfafawar thermal ya fi ban mamaki. Bayanai daga dakin gwaje-gwajen hadewar nukiliya da aka sarrafa a Qingdao sun nuna cewa yumbu na fararen fata na corundum sun tsaya tsayin daka na tsawon sa'o'i 100 na zafin jiki na 2000 ℃, kuma girman canjin ya kasance kasa da 0.01%. Wani mai bincike Lao Wang ya lanƙwasa ɗakin da ba a so ya ce: "Wannan kayan na iya tsayawa a saman rana na tsawon kwanaki biyu!"
2. "Hidden Champions" a filin Semiconductor
A cikin filin yaƙin nano-sikelin na masana'antar guntu, farin corundum ya daɗe ya zama "fasaha mai ɗorewa". Wani masana'anta na wafer a Taizhou ya yi amfani da ƙaramin foda na farin corundum 0.1μm don yanke wafers na silicon, kuma an rage yawan rugujewar gefen zuwa 0.2‰. Jagora Lao Chen ya kalli na'urar hangen nesa ya yi dariya: "Yanzu yankan wafers ya fi dacewa fiye da yanke tofu, kuma yawan amfanin gona ya kai kashi 99.98!"
Gyaran ruwan tabarau na injin lithography ya ma fi gaskiya. Bayanan da aka samu daga dakin gwaje-gwaje a birnin Beijing na jan-kafa: ana kula da ruwan tabarau da farin corundum nano-polishing water, kuma shimfidar saman ya kai λ/50. Daraktan fasaha Lao Liu ya yi nuni da cewa: "Wannan daidaitaccen daidai yake da sanya madubin jirgin sama a Tekun Pasifik!"
3. "Karkin matsawa" a cikin Masana'antar Aerospace
White corundum ita ce ta karshe a cikin sarrafa sassan Mars rover. Wani masana'anta na na'urar sararin samaniya a Xi'an yana amfani da farar fata na niƙa ƙafar corundum don niƙa braket ɗin gami na titanium, kuma ana sarrafa damuwa ta ƙasa zuwa cikin ± 5MPa. Babban Injiniya Lao Zhang ya ce da taba a bakinsa: "Da wannan matakin, Musk dole ne ya wuce taba don neman shawara!"
Wuraren injinan sararin samaniya sun kai sabon matsayi. Bayanai na wani kamfanin injin jirgin sama a Chengdu yana ɗaukar ido: farin corundum yumbu mai haɗaɗɗun ruwan wukake, tare da juriyar zafin jiki har zuwa 1600 ℃. Direban gwajin Lao Li ya kalli dashboard ɗin ya fashe: "Tare da wannan wasan kwaikwayon, injunan jet dole ne su kira baba!"
4. "Granti na Jimiri" a cikin Sabuwar Hanyar Makamashi
Farin corundum yana da kyau sosai wajen yanke guntun sandar baturi. Masana'antar baturi a cikin Ningde da aka auna: ta amfani da farin corundum yashi waya don yanke suturar graphene, ana sarrafa tsayin burr zuwa ƙasa 0.5μm. Darektan taron bita Lao Zhou ya lallaba tantanin batir ya ce cikin farin ciki: “Irin ƙarfin wannan baturi ya fi na Tesla kyau!”
5. "Bakar Fasaha Preview" na nan gaba fagen fama
Farin corundum yana da kyau a sanyaya kwamfutoci masu yawa. Wani dakin gwaje-gwaje a Hefei ya ɓullo da wani fim mai ɗaukar hoto na farin corundum na thermal conductive nano-sikelin tare da ƙarancin zafin jiki na 400W/m·K. Wani mai bincike Lao Ma ya yi fahariya: “Yanzu zafin zafi na ɗimbin raƙuman ruwa ya fi saurin shafa facin zazzabi!”
Na farko bango abu na nukiliya Fusion ne mafi wuya iko. Farar corundum mai hade yumbu na cibiyar bincike a Mianyang yana da madaidaicin lalacewa na iskar gas wanda ya ninka na kayan gargajiya sau 6. Babban Injiniya Lao Zhao ya nuna ma'aikacin mai kuma ya ce: "Ba shakka wannan kayan zai kasance karko har sai an fara samar da injinan kasuwanci!"
