Matsayin juyin juya hali na foda alumina a cikin masana'antar gogewa
Waɗanda suka yi aiki a wuraren gyaran gashi sun san cewa yana da matukar wahala a magance kayan da ke da tauri sosai - tartsatsin wuta daga injin niƙa, ƙaiƙayi a kan wurin aiki, da kuma raguwar yawan amfanin ƙasa. Fuskar shugaban ta fi ƙasan tukunya duhu. Har sai da farin foda ya yifoda na aluminaDa sauri ya shiga fagen daga, ya jawo masana'antar lalata zuwa wani sabon zamani. A yau, bari mu yi magana game da dalilin da ya sa wannan abu ya zama "mai ceto" na masana'antar zamani!
1. Mai hazaka: "jarumi mai siffar murabba'i" a cikin masana'antar gogewa
An haifi foda alumina don zama mutum mai taurin kai wanda ke cin wannan kwano na shinkafa. Abubuwa uku masu tauri suna murkushe takwarorinsu kai tsaye:
Taurin Mohs yana da yawa: Taurin Mohs yana farawa ne da 9.0, na biyu bayan lu'u-lu'u. Wani masana'antar kayan aiki a Guangdong ya auna: Lokacin yanke ƙarfe mai sauri, tsawon rayuwar ƙafafun niƙa na alumina ya ninka na yau da kullun sau 3. Tsohon shugaban Huang ya ce da sigari a bakinsa: "Na kan canza ƙafafun niƙa sau uku lokacin yanke ƙarfe mai ƙarfe, amma yanzu zan iya yin hakan ba tare da na shaƙa ba!"
Tsabta mai ban mamaki: 99.6% α-Al₂O₃ abun ciki, ƙazanta na ƙarfe an rage su zuwa ƙasa da 0.01%. Masana'antar Semiconductor ta Shanghai ta sha asara: ta amfani da mayukan goge ƙarfe don goge wafers, saman ya yi kama da alamun fata bayan watanni uku; ta amfani da foda alumina don magani, ba ta canza launi ko da a cikin baho mai acid.
Kwanciyar hankali kamar tsohon kare ne: wurin narkewa 2050℃, ƙimar faɗaɗa zafi ƙasa da 4.8×10⁻⁶/℃. Masana'antar bututun roka a Qingdao tana amfani da ita don niƙa ƙarfe masu zafi sosai, kuma canjin girman da ke ƙasa da yanayin 1500℃ bai kai ninki 6 na diamita na gashi ba.
Abin da ya fi ban mamaki shi ne yana iya canza siffarsa sau 72 - daga ƙananan ƙwayoyin micron zuwa foda mai siffar nano, yana iya zama zagaye ko lebur kamar yadda kuke so, kuma an ƙera shi musamman don warkar da duk wani rashin biyayya!
2. Yanayin juyin juya hali: "Aikin matakin fashewar makaman nukiliya" a manyan fagen daga uku
Taron bita na Semiconductor: Ƙwarewar yin ɗinki na matakin Nano
Goge wafer ɗin silicon: Fuskar micropowder mai faɗi a kan saman wafer ɗin silicon kamar na kan kankara, kuma ƙimar karce ta ragu da kashi 70% ta hanyar niƙa mai zamewa maimakon birgima na gargajiya. Babban malamin SMIC ya yi ihu: "Wannan aikin ya fi laushi fiye da ɗinki!"
Guntun silikon carbide: Ruwan goge Nano-alumina yana haƙa ramin guntu, kuma ingancin watsawar zafi yana ƙaruwa ta hanyar tasirin ramin quantum, kuma ƙimar yawan amfanin ƙasa ta tashi zuwa 99.98%. Injiniyan aikin ya duba hoton na'urar hangen nesa ta lantarki kuma ya yi alfahari da cewa: "Wannan daidaiton yana da yawa har ma da sauro da ke tsaye a kansa zai yi tsagewa!"
Substrate na Sapphire: Submicron alumina yana goge substrate na LED zuwa Ra<0.3nm, wanda ya fi madubi santsi. Shugaban Dongguan Optoelectronics Factory ya ce cikin farin ciki: "Yanzu muna yin ruwan tabarau na iPhone, kuma masu duba Apple ba za su iya gano laifinsu ba!"
Bitar Motoci: Mafi Kyawun Farashi akan Intanet
Aerospace: ƙwararrun masu ƙalubale masu tsanani
Tsarin sarrafa injin turbine da kuma tenons:Alumina nika dabaranyana aiki akan ƙarfe mai tushen nickel, kuma yana iya jure awanni 100 ba tare da rasa foda a saurin 2200 rpm ba. Direban gwaji Lao Li ya kalli allon sa ido ya yi ihu: "Da wannan juriyar lalacewa, har ma Musk dole ne ya sha sigari!"
Goge bangon roka na ciki: Foda alumina mai rufi da Nano yana rage kauri zuwa Ra0.01μm, kuma ingancin mai yana inganta da 8%. Babban injiniyan ya ce da jajayen idanu: "Wannan abu ɗaya kaɗai zai iya adana tan uku na mai kowace shekara!"
3. Kawar da kai hari kan samar da kayayyaki a cikin gida: daga "wuyan da aka makale" zuwa "kokawa ta hannu"
A da, a baya, a baya, a baya, a baya, a yi amfani da allunan alumina wajen lalata su, kamar miyar pimple, da kuma kasuwar da ta shahara, kamfanonin Amurka da Japan sun mamaye kasuwar.13. Amma yawan wuraren da aka yi amfani da semiconductor ya tilasta wa Jedi kai hari:
Harin Tsafta: Wata masana'anta a Luoyang ta ƙirƙiro wata na'urar sarrafa zafin jiki mai wayo ta murhu, kuma saurin juyawar α ya kai kashi 99.95%, kuma tsarkin ya yi daidai da Showa Denko na Japan.
Ma'anar Girman Barbashi: Kamfanonin Zhejiang suna amfani da na'urorin rarraba turbine na AI don sarrafa rarraba girman barbashi a cikin ±0.1μm. Abokan cinikin Koriya sun faɗi muƙamuƙinsu lokacin da suke duba kayan: "Wannan bayanan ya fi na'urar ganowa daidai!"
Sake haifar da shara: Tushen Shandong yana murƙushewa da sake tace sharaƙafafun niƙa, kuma rabon haɗa kayan ya ragu zuwa kashi 30%, kuma an rage farashin da kashi 40%. Daraktan bitar, Lao Zhou, ya yi dariya ya kuma tsawata: "Sharar da ake zubarwa a baya ta fi sabbin kayan aiki daraja!"
4. Fagen fama na gaba: manyan halaye guda uku sun tabbata
Kula da matakin Nano: Dakin gwaje-gwaje na Hefei ya fito da fasahar baƙar fata - fasahar adana ƙwayoyin atomic don sanya "sulke" akan ƙananan foda da kuma magance matsalar haɗuwa. Mai binciken ya ɗaga samfurin ya yi alfahari da cewa: "Yanzu goge ƙwayoyin ya fi laushi fiye da yin kakin zuma!"
Juyin Juya Halin Kore: Masana'antar Chongqing tana amfani da tsarin dawo da sharar gida mai guba don rage fitar da tan 300 na sharar da ke da haɗari kowace shekara. Mutane daga Ofishin Kare Muhalli sun zo don su ziyarce ta kuma sun yi babban yatsu: "Za ku ajiye masana'antar tace najasa!"
Kayan aikin niƙa masu wayo: Wata masana'anta a Zhengzhou ta sanya na'urar auna matsin lamba a kan ƙafafun niƙa don daidaita sigogin niƙa a ainihin lokacin. Xiao Liu, wani ƙwararren masani wanda aka haifa a shekarun 1990, ya buga a kan madannai kuma ya yi alfahari da cewa: "Yanzu daidaita sigogi ya fi sauƙi fiye da yin wasanni, kuma yawan amfanin ƙasa ya kai kashi 99.8%!"
