Isiqondiso sentuthuko yesikhathi esizayo kanye nokuthuthuka kwezobuchwepheshe kwe-white corundum micropowder
Engena eshabhu lokukhiqiza ngokunemba eShenzhen, uLi Gong wayekhathazekile nge-microscope - iqoqo lezinto zobumba ezisetshenziselwa amalensi omshini we-lithography zazinemihuzuko esezingeni eliphansi ebusweni bazo. Ngemva kokushintsha indawo entsha eyayisanda kuthuthukiswa ene-sodium ephansi.i-white corundum micropowderuketshezi olupholisha ngomkhiqizi, imihuzuko yanyamalala ngokuyisimangaliso. “Le mpuphu ifana nokuthi inamehlo, futhi ‘iluma’ amaqhubu kuphela ngaphandle kokulimaza i-substrate!” Akakwazanga ukuzibamba ngaphandle kokushaya ikhanda lakhe futhi wancoma. Lesi senzakalo sibonisa ushintsho lwezobuchwepheshe oludlulayo embonini ye-white corundum micropowder. “Amazinyo ezimboni” ayekade enothuli aguquka abe “ama-nano scalpels” okukhiqiza okusezingeni eliphezulu.
1. Amaphuzu abuhlungu embonini yamanje: Imboni yempuphu encane esendleleni yokuguqulwa
Imakethe yomhlaba wonke ye-white corundum micro powder ibonakala ichuma kakhulu - iShayina, njengomkhiqizi omkhulu kunabo bonke, ikhiqiza ngaphezu kwama-60% omkhiqizo womhlaba wonke, kanti usayizi wemakethe uzodlula amabhiliyoni ayi-10 ngo-202227. Kodwa uma ungena endaweni yefektri eGongyi, eHenan, abaphathi banikina amakhanda abo ngempahla ethengiswayo: “Izimpahla ezinentengo ephansi azikwazi ukuthengiswa, futhi izimpahla ezisezingeni eliphezulu azikwazi ukwenziwa.” Lokhu kwembula izinkinga ezimbili ezinkulu embonini:
Umthamo ophansi kakhulu: Imikhiqizo yempuphu encane yendabuko ihlanganiswa ngokuphelele, ibanjwe enkingeni yempi yentengo, futhi inzuzo yehle ngaphansi kuka-10%
Ukunikezwa okuphezulu akwanele:Impuphu encane yebanga le-semiconductorisathembele ekungenisweni kwempahla kwamanye amazwe, futhi umkhiqizo womkhiqizi othile wamazwe ngamazwe ohlanzekile ongu-99.99% uthengiswa ngentengo efinyelela ku-500,000 yuan ngethani, okuphindwe kasishiyagalombili kunemikhiqizo yasekhaya.
Okubi nakakhulu ukuthi isiqalekiso sokuvikelwa kwemvelo siya ngokuya siqina. Ngonyaka odlule, ifektri endala eZibo, eShandong yahlawuliswa imali eyizigidi ezingu-1.8 ngokweqa izinga lokusebenzisa igesi yokukhipha ugesi esitofini. Umphathi wamomotheka kabuhlungu: “Izindleko zokuvikelwa kwemvelo zidla inzuzo, kodwa uma ungafaki imishini emisha, kufanele uvale!” 8 Lapho amakhasimende angaphansi eqala ukudinga izitifiketi ze-carbon footprint, inkathi yokukhiqiza okukhulu isingene ekubaleni phansi.
2. Impumelelo kwezobuchwepheshe: Izimpi ezine ziyaqhubeka
(1) Ukulungiswa kwe-nanoscale: impi yokuguqula “impuphu encane” ibe “impuphu ecolekileyo”
Ukuncintisana ngobukhulu bezinhlayiya: Izinkampani ezihamba phambili zifinyelele ekukhiqizweni okukhulu kwezimpushana ezincane ezingaphansi kwama-nanometer angu-200, okuyindilinga eyodwa kuphela enkulu kune-coronavirus entsha (cishe ama-nanometer ayi-100).
Intuthuko yobuchwepheshe bokuhlakazeka: Inqubo yokuhlukanisa i-hydraulic sedimentation yenkampani iHanshou Jincheng ixazulula inkinga yokuhlanganiswa kwezinhlayiya ngokufaka i-composite dispersant, icindezela ukuhlakazeka kosayizi wezinhlayiya zeqoqo elifanayo lemikhiqizo kusukela ku-±30% kuya ngaphakathi ku-±5%.
Ukulawulwa kwesimo: Ukwakheka kwe-spherical kuvumela ukungqubuzana kwe-micro powder rolling ukuthi kuthathe indawo yokungqubuzana okushelelayo, futhi izinga lomonakalo wokupholisha lehla ngo-70%.6. Unjiniyela wasenkampanini yaseJapan ukuchaze kanje: “Kufana nokufaka esikhundleni se-gravel ngama-glass beads esikhundleni, futhi amathuba okuklwebheka ayancipha ngokwemvelo.”
(2) Ukuguquka okuphansi kwe-sodium: Ubumsulwa bunquma inani
Imboni ye-semiconductor iyawazonda ama-ion e-sodium – ukungcoliswa kwe-sodium okunobukhulu benhlamvu kasawoti kungabhubhisa i-wafer yonke. Impuphu ye-corundum emhlophe ene-sodium ephansi (okuqukethwe kwe-Na2O ≤ 0.02%) isibe yimpahla ethandwa kakhulu:
Ukuthuthukiswa kobuchwepheshe bokuncibilikisa i-arc: Ukuncibilikisa ukuvikelwa kwegesi okungenayo i-inert kuyasetshenziswa, futhi izinga lokuguquguquka kwe-sodium likhuphuka ngo-40%
Uhlelo lokufaka esikhundleni sezinto ezingavuthiwe: I-Kaolin isetshenziselwa ukufaka esikhundleni se-bauxite, futhi okuqukethwe yi-sodium ngokwemvelo kuncishiswa ngaphezu kuka-60%
Nakuba intengo yalolu hlobo lomkhiqizo iphakeme ngokuphindwe kathathu kuneyempuphu evamile, ayitholakali kalula. Umugqa we-sodium ephansi osanda kufakwa ekukhiqizweni efektri eJiangxi une-oda kuze kube ngu-2026.
(3)Ukukhiqiza okuluhlaza: ukuhlakanipha okuphoqelelwa ukuvikelwa kwemvelo
Ukuvuselelwa kwezinto ezingavuthiwe: Ubuchwepheshe bokuvuselela amasondo okugaya imfucuza bungakhuphula izinga lokuvuselelwa kwempuphu yemfucuza ibe ngu-85%, kunciphise izindleko ngama-yuan angu-4,000 ngethani
Ukuguquka kwenqubo: Inqubo yokwenza impuphu eyomile ithatha indawo ngokuphelele yendlela emanzi, futhi ukukhishwa kwamanzi amdaka kwehliswa kube yi-zero. Amabhizinisi aseHenan aqalise uhlelo lokubuyisa ukushisa okungcolile, futhi ukusetshenziswa kwamandla kwehle ngo-35%
Ukuguqulwa kwemfucuza eqinile: Ifektri eLiaocheng, eSifundazweni saseShandong yaguqula imfucuza yaba izinto zokwakha ezingashi, empeleni okwakhiqiza imali engenayo eyizigidi ezimbili zama-yuan minyaka yonke. Umphathi wahleka wathi: “Ngaphambilini, ukuvikelwa kwemvelo kwakuyindlela yokuthenga ukuphepha, kodwa manje sekuyindlela entsha yokwenza imali.”
(4) Ukukhiqizwa okuhlakaniphile: ukugxuma okunembile okuqhutshwa idatha
E-workshop yedijithali yaseZhengzhou Xinli, isikrini esikhulu sibonisa ijika lokusatshalaliswa kosayizi wezinhlayiya ze-micropowder ngesikhathi sangempela. "Uhlelo lokuhlunga lwe-AI lungalungisa ngokuguquguqukayo amapharamitha okuhamba komoya, ukuze izinga lokufaneleka komkhiqizo likhuphuke lisuka ku-82% liye ku-98%." Umqondisi wezobuchwepheshe wakhomba imishini esebenzayo wathi 6. Ukuqapha okuku-inthanethi kwe-laser particle size analyzer kuhlanganiswe ne-algorithm yokufunda komshini kungafeza impendulo yezinga lesibili ngokuguquguquka kwekhwalithi, kuvalelisa ngokuphelele imodi yendabuko "yokuhlola".
3. Inkundla yempi yesikhathi esizayo: ushintsho oluhle kakhulu kusukela kumasondo okugaya kuya kuma-chips
Okulandelayo "ithrekhi yegolide"I-white corundum micropowder iyavuleka:
Ukupakishwa kwe-semiconductor: okusetshenziselwa ukunciphisa nokupholisha i-silicon wafer, ngesilinganiso sokukhula kwesidingo somhlaba wonke saminyaka yonke esingaphezu kuka-25%
Insimu entsha yamandla: njengezinto zokumboza ezihlukanisa ibhethri le-lithium, ezithuthukisa ukumelana nokushisa kanye nokuqhuba kwe-ion
Okwezokwelapha: Ukupholisha okuncane kokulungiswa kwe-ceramic yamazinyo, ngesidingo sokunemba esingu-0.1 micron
Ukuvela kwe-white corundum micropowder kuyisici esincane sokuthuthukiswa kokukhiqiza eShayina. Lapho ifektri endala eZibo isebenzisa ukuphrinta kwe-3D ukwakha kabusha insimu yokugeleza kwesithando sokushisa i-calcining, futhi lapho ithimba elivela e-Chinese Academy of Sciences lihlakulela ama-microspheres e-single-crystal alumina elabhorethri, umphumela walo "mpi ye-micrometer" awuzange usanqunywa amandla okukhiqiza amanje, kodwa ngokuthi ubani owayengachaza itshe lesisekelo lokukhiqiza esikhathini esizayo ngokunemba kwe-nanometer.
