Ukuqondiswa kwentuthuko yesikhathi esizayo kanye nokuphumelela kwezobuchwepheshe kwe-white corundum micropowder
Engena endaweni yokusebenzela yokukhiqiza enembayo e-Shenzhen, u-Li Gong wayekhathazekile ngesibonakhulu - iqoqo lama-substrates e-ceramic asetshenziselwa amalensi omshini we-lithography ayenemihuzuko enezinga le-nano endaweni yawo. Ngemva kokufaka esikhundleni se-low-sodium esanda kuthuthukiswai-white corundum micropowderuketshezi olucwebezelayo ngomkhiqizi, imihuzuko yanyamalala ngokuyisimangaliso. Le mpushana ifana nokuthi inamehlo, futhi 'iluma' kuphela amaqhubu ngaphandle kokulimaza isitsha esingaphansi!” Wahluleka ukuzibamba washaya ngempama ebabaza. Lesi sigameko sibonisa ukuguqulwa kwezobuchwepheshe imboni ye-white corundum micropowder eyenziwayo. "Amazinyo ezimboni" ayekade enothuli ashintsha abe "i-nano scalpels" yokukhiqiza okuphezulu.
1. Amaphuzu obuhlungu embonini yamanje: Imboni yempushana encane esempambanweni yezinguquko
Imakethe yomhlaba wonke ye-corundum micro powder ibonakala idlondlobala - i-China, njengomkhiqizi omkhulu kunayo yonke, yenza ngaphezu kuka-60% wokukhiqiza emhlabeni wonke, futhi usayizi wemakethe uzodlula izigidi eziyizinkulungwane ezingu-10 ngo-2022227. Kodwa uma ungena endaweni yefekthri e-Gongyi, e-Henan, abaphathi banikine amakhanda abo ekusungulweni kwempahla: "Impahla enenani eliphansi, ayikwazi ukuthengiswa." Lokhu kuveza izingqinamba ezimbili ezinkulu embonini:
Umthamo osezingeni eliphansi: Imikhiqizo yendabuko yempushana encane ihlanganiswa ngokujulile, ibanjwe ku-vortex yamanani entengo, futhi umkhawulo wenzuzo wehle ngaphansi kwe-10%
Ukunikezwa kwezinga eliphezulu akwanele:I-semiconductor-grade micro powderusathembele ekuthengisweni kwamanye amazwe, futhi umkhiqizo wokuhlanzeka womkhiqizi othile wamazwe ngamazwe uthengiswa ngentengo efika ku-500,000 yuan toni, okuyiphinda izikhathi ezingu-8 kunemikhiqizo yasekhaya.
Okubi nakakhulu ukuthi isiqalekiso sokuvikelwa kwemvelo siya ngokuya siqina. Ngonyaka odlule, ifekthri endala eZibo, eShandong yahlawuliswa izigidi ezingu-1.8 ngokweqa izinga lokushiswa kwegesi ephuma kuhhavini. Umphathi wamamatheka kabuhlungu: “Izindleko zokuvikela imvelo zidla inzuzo, kodwa uma ungawafaki imishini emisha, kufanele uvale!” 8 Ngenkathi amakhasimende aphansi komfula eqala ukudinga izitifiketi ze-carbon footprint, inkathi yokukhiqiza okubanzi ingene ekubaleni.
2. Impumelelo kwezobuchwepheshe: Izimpi ezine ziyaqhubeka
(1) Ukulungiswa kwe-Nanoscale: impi yokuguqula "impushana encane" ibe "impushana enhle"
Ukuncintisana kosayizi wezinhlayiya: Izinkampani ezihamba phambili zithole ukukhiqizwa ngobuningi bezimpushana ezincane ezingaphansi kwama-nanometers angama-200, okuyindilinga eyodwa kuphela enkulu kune-coronavirus entsha (cishe ama-nanometer ayi-100).
Ukuphumelela kobuchwepheshe bokuhlakazwa: Inqubo yokuhlukanisa i-hydraulic sedimentation ye-Hanshou Jincheng Company enelungelo lobunikazi ixazulula inkinga yokuhlanganisa izinhlayiyana ngokwengeza isisabalalisi esiyinhlanganisela, ukucindezela ukuhlakazwa kosayizi wezinhlayiyana zeqoqo elifanayo lemikhiqizo ukusuka ku-±30% ukuya ngaphakathi ku-±5%.
Ukulawulwa kwe-morphology: I-Sphericization ivumela ukungqubuzana kwempushana encane esikhundleni sokuslayida, futhi izinga lomonakalo wokupholisha lehla ngo-70%.6. Unjiniyela wenkampani yaseJapane wakuchaza ngokuthi: “Kufana nokufaka ubuhlalu bengilazi esikhundleni setshe, futhi amathuba okuklwebheka ayancipha ngokwemvelo.”
(2) Ukuguqulwa kwe-sodium ephansi: Ukuhlanzeka kunquma inani
Imboni ye-semiconductor iyawazonda ama-ion e-sodium - ukungcola kwe-sodium elingana nohlamvu lukasawoti kungabhubhisa yonke i-wafer. I-low-sodium white corundum powder (okuqukethwe kwe-Na2O ≤ 0.02%) isiphenduke impahla eshisayo:
Ukuthuthukiswa kobuchwepheshe bokuncibilika kwe-Arc: Ukuncibilika kokuvikela igesi okungenayo kwamukelwa, futhi izinga lokuvuvukalisa kwe-sodium lenyuka ngo-40%
Uhlelo lokubuyisela impahla eluhlaza: I-Kaolin isetshenziselwa ukufaka esikhundleni se-bauxite, futhi okuqukethwe kwe-sodium ngokwemvelo kwehliswa ngaphezu kuka-60%
Nakuba intengo yalolu hlobo lomkhiqizo iphakeme izikhathi ezi-3 kunaleyo yempushana evamile, iyashoda. Ulayini we-sodium ephansi osanda kufakwa ekukhiqizeni efektri e-Jiangxi unama-oda kuze kube ngu-2026.
(3)Ukukhiqiza okuluhlaza: ubuhlakani obuphoqelelwe ukuvikelwa kwemvelo
Ukugaywa kabusha kwezinto ezingavuthiwe: Ubuchwepheshe bokugaya kabusha isondo lokugaya kungakhuphula izinga lokugaywa kabusha kwempushana ibe ku-85%, kwehlise izindleko ngamayuan angu-4,000 ngethani.
Uguquko lwenqubo: Inqubo yokwenza impushana eyomile ingena esikhundleni ngokuphelele sendlela emanzi, futhi ukuchithwa kwamanzi angcolile kuyehla kube ziro. Amabhizinisi akwaHenan athule uhlelo lokubuyisa ukushisa kukadoti, futhi ukusetshenziswa kwamandla kwehle ngo-35%.
Ukuguqulwa kukadoti oqinile: Imboni ese-Liaocheng, eSifundazweni SaseShandong yaphendula imfucumfucu yaba izinto zokwakha ezingashi, empeleni ezikhiqize izigidi ezimbili zamayuan emalini engenayo unyaka ngamunye. Ubasi wancokola: “Ngaphambili, ukuvikelwa kwemvelo bekuyindlela yokuthenga ukuphepha, kodwa manje sekuyindlela entsha yokwenza imali.”
(4) Ukukhiqiza okuhlakaniphile: ukweqa ukunemba okuqhutshwa yidatha
Kushabhu yedijithali ye-Zhengzhou Xinli, isikrini esikhulu sibonisa ijika lokusabalalisa usayizi wezinhlayiyana ze-micropowder ngesikhathi sangempela. "Uhlelo lokuhlunga lwe-AI lungakwazi ukulungisa amapharamitha wokugeleza komoya, ukuze izinga lokufaneleka lomkhiqizo linyuke lisuka ku-82% liye ku-98%. Umqondisi wezobuchwepheshe wakhomba imishini egijimayo wathi 6. Ukuqapha ku-inthanethi kokuhlaziya usayizi wezinhlayiyana ze-laser kuhlanganiswe ne-algorithm yokufunda yomshini kungafinyelela impendulo yezinga lesibili ngokuguquguquka kwekhwalithi, ukuvalelisa ngokuphelele kumodi yendabuko "yokulandela ukuhlolwa".
3. Inkundla yempi yesikhathi esizayo: uguquko oluhle ukusuka kumasondo okugaya ukuya kuma-chips
Okulandelayo "ithrekhi yegolide” ye-white corundum micropowder iyavuleka:
Ukupakishwa kweSemiconductor: kusetshenziselwa ukucwecwa kwe-silicon wafer nokupholisha, ngezinga lokukhula kwesidingo saminyaka yonke esingaphezu kwama-25%
Inkambu entsha yamandla: njenge-lithium battery separator coating material, ithuthukisa ukumelana nokushisa kanye ne-ion conductivity
I-Biomedical: Ukupholishwa kwe-Nano-polisha kokubuyiselwa kwe-ceramic yamazinyo, nemfuneko yokunemba ye-micron engu-0.1
Ukuvela kwe-white corundum micropowder kuyi-microcosm yokuthuthukiswa kokukhiqizwa kwe-China. Lapho ifektri endala eZibo isebenzisa ukunyathelisa kwe-3D ukuze yakhe kabusha inkambu yokugeleza yeziko lokubala, futhi lapho ithimba elivela e-Chinese Academy of Sciences litshala ama-microspheres e-alumina e-crystal eyodwa elabhorethri, umphumela wale "mpi ye-micrometer" wawungasanqunywa amandla okukhiqiza amanje, kodwa ngubani ongachaza isisekelo sokukhiqiza ngokunemba kwesikhathi esizayo nge-nanometer.
