Indima yokuguqula i-alumina powder embonini yokuhluza
Labo abake basebenza ezindaweni zokusebenzela ezirhabaxa bayazi ukuthi kuyikhanda elibuhlungu ukubhekana nezinto zokuqina okuphezulu - izinhlansi ezivela esondweni lokugaya, imihuzuko endaweni yokusebenza, kanye nokwehla kwesilinganiso sesivuno. Ubuso bomphathi bumnyama kunephansi lebhodwe. Kuze kube yilapho impuphu emhlophe yeimpuphu ye-aluminayagijimela empini, yadonsela imboni enzima enkathini entsha. Namuhla, ake sixoxe ngokuthi kungani le nto isibe “umsindisi osilayo” wemboni yanamuhla!
1. Onekhono: “iqhawe elinonxande” embonini yokuhlukumeza
Impuphu ye-alumina izalwa ukuba yindoda eqinile edla lesi sitsha selayisi. Izici ezintathu eziqinile zichoboza ontanga bayo ngqo:
Ukuqina kuphezulu: Ukuqina kwe-Mohs kuqala ku-9.0, kwesibili ngemuva kwedayimane. Ifektri yamathuluzi eGuangdong ilinganisiwe: Lapho kusikwa insimbi enesivinini esikhulu, impilo yamasondo okugaya e-alumina iphindwe kathathu kune-abrasives evamile. Inkosi endala uHuang yathi ephethe ugwayi emlonyeni wayo: “Bengivame ukushintsha isondo lokugaya kathathu lapho kusikwa insimbi ye-alloy, kodwa manje sengingakwenza konke ngaphandle kokuphefumula!”
Ubumsulwa obumangalisayo: okuqukethwe okungu-99.6% kwe-α-Al₂O₃, ukungcola kwensimbi kuncishisiwe kube ngaphansi kuka-0.01%. I-Shanghai Semiconductor Factory ilahlekelwe: isebenzisa ama-abrasives aqukethe insimbi ukupholisha ama-wafer, ubuso babukeka njengezimpawu zokubola ngemva kwezinyanga ezintathu; isebenzisa i-alumina powder ukwelapha, ayishintshi umbala ngisho nasezihlanjeni ezine-asidi.
Ukuqina kokushisa kufana nenja endala: iphuzu lokuncibilika lingu-2050℃, i-coefficient yokwandisa ukushisa iphansi njengo-4.8×10⁻⁶/℃. Ifektri ye-rocket nozzle eQingdao iyisebenzisela ukugaya ama-alloy okushisa okuphezulu, futhi ukuguquguquka kosayizi ngaphansi kwendawo engu-1500℃ kungaphansi kokuphindwe kasithupha kobubanzi bezinwele.
Okumangalisa kakhulu ukuthi ingashintsha isimo sayo izikhathi ezingu-72 - kusukela ezinhlayiyeni ezisicaba ezingeni le-micron kuya ku-nano-level powder eyindilinga, ingaba yindilinga noma ibe yisicaba ngendlela othanda ngayo, futhi yenzelwe ngokukhethekile ukwelapha zonke izinhlobo zokungalaleli!
2. Isimo soguquko: “Ukusebenza kwezinga lokuqhuma kwenyukliya” ezinkundleni zempi ezintathu ezinkulu
I-workshop ye-semiconductor: Amakhono okuthunga asezingeni le-Nano
Ukupholisha i-silicon wafer: I-flat alumina micropowder idlula phezu kwe-silicon wafer njengokuskeyitha, futhi izinga lokuklwebheka lehla ngo-70% ngokugaya ngokushelela esikhundleni sokugingqa okujwayelekile. Ingcweti ye-SMIC yamemeza: “Lo msebenzi ubucayi kakhulu kunokuhlobisa!”
I-chip ye-silicon carbide: Uketshezi olupholisha i-nano-alumina lubhoboza igebe le-chip, futhi ukusebenza kahle kokushabalalisa ukushisa kuthuthukiswa umphumela we-quantum tunnel, futhi izinga lokukhiqiza likhuphuka lifike ku-99.98%. Unjiniyela wephrojekthi washaya isithombe se-electron microscope waqhosha wathi: “Lokhu kunemba kuphakeme kangangokuthi ngisho nomiyane omi phezu kwawo kuzodingeka uqhekeke!”
I-substrate yesafire: I-Submicron alumina ipholisha i-substrate ye-LED ibe yi-Ra<0.3nm, ebushelelezi kunesibuko. Umphathi we-Dongguan Optoelectronics Factory uthe ngenjabulo: “Manje sesenza amalensi e-iPhone, futhi abahloli be-Apple abakwazi ukuthola amaphutha kuwo!”
Indawo yokusebenzela izimoto: izindleko eziphansi ku-inthanethi
Izindiza: ochwepheshe bezinselelo ezinkulu
Ukucubungula i-turbine blade mortise kanye ne-tenon:Isondo lokugaya le-AluminaIsebenza ku-alloy esekelwe ku-nickel, futhi ingamelana namahora ayi-100 ngaphandle kokulahlekelwa yimpuphu ngesivinini esingu-2200 rpm. Umshayeli wokuhlola uLao Li wabuka isikrini sokuqapha wamemeza: “Ngalokhu kumelana nokuguguleka, ngisho noMusk kufanele adlulise ugwayi!”
Ukupholisha udonga lwangaphakathi lwe-rocket nozzle: Impuphu ye-alumina ehlanganiswe ne-nano inciphisa ubulukhuni obuyi-Ra0.01μm, futhi ukusebenza kahle kukaphethiloli kuthuthukiswa ngo-8%. Unjiniyela oyinhloko uthe ngamehlo abomvu: “Le nto eyodwa iyodwa ingonga amathani amathathu kaphethiloli minyaka yonke!”
3. Ukuhlasela kokukhiqiza kwasekhaya: kusukela “entanyeni enamathele” kuya “ekubambeni ngengalo”
Ama-abrasives e-alumina asekhaya ayevame ukuba “yindaba edabukisayo” – ukumelana nokuguguleka okubi, amaqoqo angazinzile, ukuhlanganiswa kwe-nano powder njengesobho lama-pimple, kanye nemakethe ephezulu yayilawulwa yizinkampani zaseMelika nezaseJapane13. Kodwa igagasi lokwenziwa kwe-semiconductor laphoqa ukuhlasela kweJedi:
Ukuhlaselwa kobumsulwa: Ifektri eLuoyang ithuthukise ukulawula izinga lokushisa okuhlakaniphile kwesithando somlilo se-arc, kanti izinga lokuguqulwa kwesigaba se-α lifinyelele ku-99.95%, futhi ubumsulwa bulingana nobeShowa Denko yaseJapan.
I-metaphysics yobukhulu bezinhlayiya: Izinkampani zaseZhejiang zisebenzisa ama-AI turbine classifiers ukulawula ukusatshalaliswa kobukhulu bezinhlayiya ngaphakathi kuka-±0.1μm. Amakhasimende aseKorea ayekethise lapho ehlola izimpahla: “Le datha inembe kakhulu kune-detector!”
Ukuzalwa kabusha kwemfucuza: Isisekelo saseShandong siyaphula futhi sihlanze kabusha imfucuzaamasondo okugaya, kanti isilinganiso sokuxubana sehlisiwe saba ngu-30%, kanti izindleko zehlisiwe ngo-40%. Umqondisi we-workshop, uLao Zhou, wahleka futhi wathethisa: “Udoti owawulahlwa ngokulahlekelwa manje usubaluleke kakhulu kunezinto ezintsha!”
4. Inkundla yempi yesikhathi esizayo: izitayela ezintathu ezinkulu zizinzile
Ukulawulwa kwezinga le-nano: Ilabhorethri yaseHefei iqhamuke nobuchwepheshe obumnyama - ubuchwepheshe bokubeka ungqimba lwe-athomu ukuze kufakwe "izikhali" kuma-micro powders nokuxazulula inkinga yokuhlangana. Umcwaningi waphakamisa isampula waqhosha wathi: "Manje ukupholisha ama-chip kubushelelezi kunokufaka i-wax!"
I-Green Revolution: Isitshalo saseChongqing sisebenzisa uhlelo lokubuyisa i-asidi yemfucuza ukunciphisa ukukhishwa kwamathani angu-300 emfucuza eyingozi minyaka yonke. Abantu abavela kwi-Environmental Protection Bureau bafika bezosivakashela futhi baphakamisa isithupha: “Uzosusa isitshalo sokuhlanza indle!”
Amathuluzi okugaya ahlakaniphile: Ifektri eZhengzhou ifake inzwa yokucindezela esondweni lokugaya ukuze ilungise amapharamitha okugaya ngesikhathi sangempela. UXiao Liu, uchwepheshe owazalwa ngawo-1990, wabhala kukhibhodi futhi waqhosha wathi: “Manje ukulungisa amapharamitha kulula kunokudlala imidlalo, futhi izinga lokukhiqiza selifinyelele ku-99.8%!”
