Matsayin juyin juya hali na alumina foda a cikin masana'antar abrasive
Wadanda suka yi aiki a cikin tarurrukan abrasive sun san cewa ciwon kai ne don magance manyan taurin kayan aiki - tartsatsi daga injin niƙa, tarkace akan aikin aiki, da raguwar yawan amfanin ƙasa. Fuskar maigida ta fi kasan tukunya duhu. Har sai farin foda naalumina fodaya garzaya cikin fagen fama, ya ja masana'antar lalata cikin wani sabon zamani. A yau, bari muyi magana game da dalilin da yasa wannan abu ya zama "mai ceto" na masana'antar zamani!
1. Mai basira: "Jarumi hexagonal" a cikin masana'antar abrasive
Alumina foda an haife shi don zama mai tauri wanda ya ci wannan kwanon shinkafa. Kaddarorin masu ƙarfi guda uku suna murkushe takwarorinta kai tsaye:
Taurin yana da girma: Taurin Mohs yana farawa daga 9.0, na biyu kawai zuwa lu'u-lu'u. Masana'antar kayan aiki a Guangdong tana auna: Lokacin yanke ƙarfe mai sauri, rayuwar ƙafafun alumina ya ninka sau 3 na abrasives na yau da kullun. Tsoho maigida Huang ya ce da sigari a bakinsa: “Nakan canza keken niƙa sau uku sa’ad da nake yankan ƙarfe, amma yanzu zan iya yin hakan ba tare da shan iska ba!”
Tsabta mai ban mamaki: 99.6% α-Al₂O₃ abun ciki, ƙazantattun ƙarfe ana murƙushe su zuwa ƙasa da 0.01%. Kamfanin masana'antar Semiconductor na Shanghai ya sami asara: ta yin amfani da abrasives mai ɗauke da ƙarfe don goge wafers, saman ya yi kama da alamar aladu bayan watanni uku; Yin amfani da foda alumina don magancewa, ba ya canza launi ko da a cikin wanka na acid.
Thermal kwanciyar hankali kamar tsohon kare: narkewa batu 2050 ℃, thermal fadada coefficient a matsayin low as 4.8 × 10⁻⁶ / ℃. Wata masana'antar bututun roka a Qingdao tana amfani da ita don niƙa gami da zafi mai zafi, kuma girman canjin yanayi a ƙarƙashin yanayin 1500 ℃ bai wuce ninki 6 na diamita na gashi ba.
Abin da ya fi ban mamaki shi ne cewa yana iya canza siffarsa sau 72 - daga micron-level flat particles zuwa nano-level spherical foda, yana iya zama zagaye ko lebur kamar yadda kuke so, kuma an tsara shi musamman don warkar da kowane irin rashin biyayya!
2. Halin juyin juya hali: "Ayyukan matakin fashewar nukiliya" a cikin manyan wuraren yaƙi guda uku
Semiconductor bitar: Ƙwarewar ƙirar ƙirar Nano-matakin
Silicon wafer polishing: Flat alumina micropowder skims a saman saman siliki wafer kamar skating, kuma karce adadin ya ragu da 70% ta zamiya nika maimakon na gargajiya birgima. Maigidan na SMIC ya ce: “Wannan aikin ya fi aski!”
Silicon carbide guntu: Nano-alumina polishing ruwa drills a cikin guntu rata, da zafi watsar da yadda ya dace ya inganta ta hanyar jimla rami sakamakon, kuma yawan amfanin ƙasa ya haura zuwa 99.98%. Injiniyan aikin ya leƙa hoton na’urar microscope kuma ya yi fahariya: “Wannan daidaici yana da girma har sauro da ke tsaye a kansa zai rabu!”
Sapphire Substrate: Submicron alumina yana goge madaidaicin LED zuwa Ra <0.3nm, wanda yafi santsi fiye da madubi. Shugaban masana'antar Dongguan Optoelectronics Factory ya ce cikin farin ciki: "Yanzu muna yin ruwan tabarau na iPhone, kuma masu binciken Apple ba za su iya samun laifinsu ba!"
Bitar mota: kisa akan layi
Aerospace: ƙwararrun ƙalubalen ƙalubale
Turbine ruwan wukake da sarrafa jijiya:Alumina niƙa dabaranyana aiki akan alloy na tushen nickel, kuma yana iya jure sa'o'i 100 ba tare da rasa foda ba a saurin 2200 rpm. Direban gwajin Lao Li ya kalli allon sa ido ya yi ihu: "Tare da wannan juriya, har Musk ya wuce sigari!"
Roka bututun ƙarfe na ciki bango polishing: Nano-rufi alumina foda yana rage roughness zuwa Ra0.01μm, kuma man fetur yana inganta da 8%. Babban injiniyan ya ce da jajayen idanu: “Wannan abu ɗaya kaɗai zai iya ajiye tan uku na man fetur kowace shekara!”
3. Rikici na samar da gida: daga "manne wuya" zuwa "kokawa"
Alumina abrasives na cikin gida sun kasance "labari mai ban tausayi" - rashin juriya mara kyau, batches mara kyau, nano foda agglomeration kamar pimple miya, kuma babban kasuwa ya kasance mallakin kamfanoni na Amurka da Japan13. Amma kalaman na semiconductor localization tilasta Jedi counterattack:
Harin Tsafta: Wata masana'anta a Luoyang ta haɓaka wutar lantarki mai sarrafa zafin jiki, kuma ƙimar juzu'in α ya kai 99.95%, kuma tsarkin ya yi daidai da Showa Denko na Japan.
Girman ɓangarorin metaphysics: Kamfanonin Zhejiang suna amfani da nau'ikan injin turbine na AI don sarrafa girman girman barbashi tsakanin ± 0.1μm. Abokan cinikin Koriya sun jefar da haƙarsu lokacin da suke duba kayan: "Wannan bayanan sun fi na'urar ganowa daidai!"
Sharar sake haifuwa: Shandong tushe yana murkushewa kuma yana sake gyara sharar gidaniƙa ƙafafun, kuma an rage adadin admixture zuwa 30%, kuma an rage farashin da 40%. Daraktan bitar, Lao Zhou, ya yi dariya da tsawa: "Sharar da a da ake zubarwa a cikin hasara ta fi sabbin kayayyaki daraja!"
4.Filin yaƙi na gaba: manyan al'amuran uku sun tabbata
Nano-matakin iko: Hefei dakin gwaje-gwaje ya zo da baƙar fata fasaha - atomic Layer deposition fasaha don sanya "makamai" a kan micro powders da kuma warware matsalar agglomeration. Mai binciken ya ɗauki samfurin kuma ya yi fahariya: "Yanzu goge goge ya fi santsi fiye da kakin zuma!"
Koren Juyin Juya Hali: Tsibirin Chongqing yana amfani da tsarin dawo da sinadarin acid don rage fitar da tan 300 na datti a kowace shekara. Mutane daga Ofishin Kare Muhalli sun zo ziyara kuma suka ba da babban yatsa: "Za ku kori masana'antar sarrafa najasa!"
Kayan aikin niƙa mai wayo: Wata masana'anta a Zhengzhou ta sanya na'urar firikwensin matsa lamba akan injin niƙa don daidaita sigogin niƙa a ainihin lokacin. Xiao Liu, masanin fasaha da aka haife shi a cikin 1990s, ya buga akan madannai kuma ya yi alfahari: "Yanzu daidaita sigogi ya fi sauƙi fiye da wasa, kuma yawan amfanin ƙasa ya kai kashi 99.8!"
