Indima eguqukayo yomgubo we-alumina kwishishini lokurhawuzelela
Abo basebenze kwiindawo zokusebenzela ezirhabaxa bayazi ukuba kuyintlungu ukujongana nezinto eziqinileyo kakhulu - iintlantsi ezivela kwivili lokusila, imikrwelo kwindawo yokusebenza, kunye nokuhla kwesantya sesivuno. Ubuso bomphathi bumnyama kunomgangatho wembiza. Kude kube ngumgubo omhlophe weumgubo we-aluminaYangena ngokukhawuleza edabini, yatsala imboni erhabaxa yaya kwixesha elitsha. Namhlanje, masithethe ngesizathu sokuba le nto ibe “ngumsindisi osilayo” wemboni yanamhlanje!
1. Italente: “iqhawe elinomqolo osicaba” kwishishini lokubetha
Umgubo we-alumina uzalelwe ukuba yindoda eyomeleleyo etya esi sitya serayisi. Iimpawu ezintathu eziqinileyo zityumza ngqo ontanga bayo:
Ukuqina kuphezulu: Ukuqina kweMohs kuqala kwi-9.0, kulandele idayimani kuphela. Umzi-mveliso wezixhobo eGuangdong ulinganise: Xa kusikwa intsimbi ekhawulezayo, ubomi bamavili okugaya e-alumina buphindwe kathathu kunobo be-abrasives eqhelekileyo. Inkosi endala uHuang yathi icuba emlonyeni wayo: “Bendisoloko nditshintsha ivili lokugaya kathathu xa ndisika intsimbi ye-alloy, kodwa ngoku ndingakwenza konke ngaphandle kokuphefumla!”
Ubumsulwa obumangalisayo: 99.6% umxholo we-α-Al₂O₃, ukungcola kwesinyithi kuyancitshiswa kube ngaphantsi kwe-0.01%. I-Shanghai Semiconductor Factory ilahlekelwe yilahleko: ukusebenzisa ii-abrasives ezine-iron ukupolisha ii-wafers, umphezulu wawubonakala ngathi zii-pockmarks emva kweenyanga ezintathu; ukusebenzisa umgubo we-alumina ukunyanga, akutshintshi umbala nokuba kwiibhafu ezine-asidi.
Uzinzo lobushushu lufana nenja endala: iqondo lokunyibilika liyi-2050℃, i-thermal expansion coefficient iphantsi njenge-4.8×10⁻⁶/℃. Umzi-mveliso we-rocket nozzle eQingdao uyisebenzisela ukugaya ii-alloys ezinobushushu obuphezulu, kwaye ukuguquguquka kobukhulu obuphantsi kwe-1500℃ bungaphantsi kwe-6 ubukhulu bonwele.
Okumangalisayo ngakumbi kukuba ingatshintsha imo yayo izihlandlo ezingama-72 – ukusuka kumasuntswana athambileyo akwinqanaba le-micron ukuya kwi-nano-level spherical powder, ingaba yingqukuva okanye ibe tyaba njengoko ufuna, kwaye yenzelwe ngokukodwa ukunyanga zonke iintlobo zokungathobeli!
2. Indawo yotshintsho: "Ukusebenza kwinqanaba lokuqhuma kwenyukliya" kwiindawo ezintathu ezinkulu zemfazwe
Iworkshop ye-semiconductor: Izakhono zokuluka ezikumgangatho we-nano
Ukupholisha i-silicon wafer: I-flat alumina micropowder idlula phezu komphezulu we-silicon wafer njengokuskeyitha, kwaye izinga lokukrwela liyehla ngama-70% ngokuslayida endaweni yokuqengqeleka kwendabuko. Ingcali ye-SMIC yakhwaza yathi: “Lo msebenzi uthambile ngakumbi kunomthungo!”
Itshiphu ye-silicon carbide: I-Nano-alumina polishing liquid drills kwi-chip gap, kwaye ukusebenza kakuhle kokusasazwa kobushushu kuphuculwe yi-quantum tunnel effect, kwaye izinga lemveliso linyuka liye kuma-99.98%. Injineli yeprojekthi yachukumisa umfanekiso we-electron microscope yaza yaqhayisa yathi: “Olu lwazi luphezulu kangangokuba nengcongconi emi phezu kwayo kuya kufuneka iqhekeke!”
I-substrate yesafire: I-Submicron alumina ipolisha i-substrate ye-LED ibe yi-Ra<0.3nm, ethambileyo kunesipili. Umphathi weDongguan Optoelectronics Factory uthe ngovuyo: “Ngoku senza iilensi ze-iPhone, kwaye abahloli be-Apple abanakufumana siphoso kuzo!”
Indawo yokusebenzela iimoto: ixabiso liphantsi kwi-intanethi
I-Aerospace: iingcali ezijongene nemingeni enzima
Ukulungiswa kwe-turbine blade mortise kunye ne-tenon:Ivili lokugaya le-AluminaIsebenza kwi-alloy esekwe kwi-nickel, kwaye inokumelana neeyure ezili-100 ngaphandle kokulahlekelwa ngumgubo ngesantya se-2200 rpm. Umqhubi wovavanyo uLao Li wajonga isikrini sokujonga waza wakhwaza wathi: “Ngalo mandla okuguguleka, noMusk kufuneka adlulise icuba!”
Ukupholisha udonga ngaphakathi kwe-rocket nozzle: Umgubo we-alumina ogqunywe nge-nano-coated unciphisa uburhabaxa ukuya kwi-Ra0.01μm, kwaye ukusebenza kakuhle kwepetroli kuphuculwe nge-8%. Injineli eyintloko yathi ngamehlo abomvu: “Le nto inye yodwa inokonga iitoni ezintathu zepetroli minyaka le!”
3. Uhlaselo lokulwa nemveliso yasekhaya: ukusuka “entanyeni enamatheleyo” ukuya “ekulweni ngengalo”
Iibrasives ze-alumina zasekhaya zazikade "ziyibali elibuhlungu" - ukungagugi kakuhle, iibhetshi ezingazinzanga, ukuhlanganiswa kwe-nano powder njengesuphu yamaqhuqhuva, kwaye imakethi ephezulu yayilawulwa ziinkampani zaseMelika nezaseJapan13. Kodwa igagasi lokwenziwa kwe-semiconductor localization lanyanzela uhlaselo lokulwa neJedi:
Uhlaselo loBumsulwa: Umzi-mveliso eLuoyang uphuhlise ulawulo lobushushu olukrelekrele lwe-arc furnace, kwaye izinga lokuguqulwa kwesigaba se-α lifikelele kwi-99.95%, kwaye ubumsulwa bulingana nobeShowa Denko yaseJapan.
Ubungakanani bezinto ezisetyenziswa kwi-particles metaphysics: Iinkampani zaseZhejiang zisebenzisa ii-AI turbine classifiers ukulawula ukusasazwa kobungakanani bezinto ezisetyenziswa kwi-particles ngaphakathi kwe-±0.1μm. Abathengi baseKorea bathe gqolo xa behlola iimpahla: “Le datha ichanekile ngaphezu kwe-detector!”
Ukuzalwa kwakhona kwenkunkuma: Isiseko saseShandong siyayityumza kwaye siyicoca kwakhona inkunkumaamavili okugaya, kwaye umlinganiselo wokuxuba uncitshisiwe ukuya kwi-30%, kwaye iindleko zincitshisiwe ngama-40%. Umlawuli weworkshop, uLao Zhou, wahleka waza wakhalimela wathi: “Inkunkuma eyayikade ilahlwa xa ilahlekile ngoku ixabiseke ngaphezu kwezinto ezintsha!”
4. Idabi lexesha elizayo: iindlela ezintathu eziphambili zizinzile
Ulawulo lwenqanaba le-nano: Ilebhu yaseHefei ivelise iteknoloji emnyama - iteknoloji yokufaka umaleko weathomu ukuze ibeke "isikrweqe" kwimibhobho emincinci kwaye isombulule ingxaki yokuhlanganiswa. Umphandi uphakamise isampulu waza waqhayisa wathi: "Ngoku ukupolisha iitshiphusi kuthambile kune-wax!"
Inguqu Eluhlaza: Isityalo saseChongqing sisebenzisa inkqubo yokubuyisa i-asidi yenkunkuma ukunciphisa ukukhutshwa kweetoni ezingama-300 zenkunkuma eyingozi minyaka le. Abantu abavela kwi-Environmental Protection Bureau beza kutyelela baza baphakamisa isandla besithi: “Uza kuyisusa isityalo sokucocwa kwamanzi amdaka!”
Izixhobo zokugaya ezikrelekrele: Umzi-mveliso eZhengzhou ufake i-sensor yoxinzelelo kwivili lokusila ukuze ulungise iiparameter zokusila ngexesha langempela. UXiao Liu, ingcali eyazalwa ngeminyaka yoo-1990, wabhala kwikhibhodi waza waqhayisa wathi: “Ngoku ukulungisa iiparameter kulula kunokudlala imidlalo, kwaye izinga lemveliso lifikelele kwi-99.8%!”
