Kev taw qhia txog kev loj hlob yav tom ntej thiab kev tshawb pom tshiab ntawm cov hmoov av dawb corundum
Thaum taug kev mus rau hauv lub chaw ua haujlwm tsim khoom siv precision hauv Shenzhen, Li Gong txhawj xeeb txog lub tshuab microscope - ib pawg ntawm cov khoom siv ceramic siv rau cov iav lithography muaj cov khawb nano-level ntawm lawv cov nplaim. Tom qab hloov cov khoom tshiab tsim qis-sodiumhmoov av dawb corundumua kua txhuam nrog lub chaw tsim khoom, cov khawb tau ploj mus zoo kawg nkaus. "Cov hmoov no zoo li nws muaj qhov muag, thiab nws tsuas yog 'tom' cov pob yam tsis ua rau lub substrate mob!" Nws tsis tuaj yeem pab tab sis ntaus nws lub taub hau thiab qhuas. Qhov xwm txheej no qhia txog kev hloov pauv thev naus laus zis uas kev lag luam micropowder dawb corundum tab tom dhau mus. Cov "hniav kev lag luam" uas ib zaug muaj plua plav tab tom hloov mus ua "nano scalpels" rau kev tsim khoom siab.
1. Cov teeb meem kev lag luam tam sim no: Kev lag luam hmoov me me nyob ntawm txoj kev sib tshuam ntawm kev hloov pauv
Lub lag luam thoob ntiaj teb dawb corundum micro hmoov zoo li yuav loj hlob - Tuam Tshoj, ua tus tsim khoom loj tshaj plaws, suav txog ntau dua 60% ntawm kev tsim khoom thoob ntiaj teb, thiab qhov loj ntawm kev ua lag luam yuav tshaj 10 billion hauv 2022227. Tab sis thaum koj taug kev mus rau hauv thaj chaw Hoobkas hauv Gongyi, Henan, cov thawj coj co taub hau ntawm cov khoom muag: "Cov khoom pheej yig tsis tuaj yeem muag tau, thiab cov khoom kim heev tsis tuaj yeem ua tau." Qhov no qhia txog ob qhov teeb meem loj hauv kev lag luam:
Muaj peev xwm ntau dhau: Cov khoom siv hmoov me me ib txwm muaj kev sib xyaw ua ke, ntes tau hauv kev sib ntaus sib tua nqi, thiab cov nyiaj tau los poob qis dua 10%
Cov khoom siv kim heev tsis txaus:Hmoov micro semiconductortseem vam khom kev xa khoom tuaj, thiab qee lub tuam txhab tsim khoom thoob ntiaj teb cov khoom lag luam 99.99% purity raug muag ntawm tus nqi txog li 500,000 yuan ib tuj, uas yog 8 npaug ntawm cov khoom lag luam hauv tsev
Qhov loj dua yog tias qhov kev foom phem rau kev tiv thaiv ib puag ncig tau nruj zuj zus. Xyoo tas los, ib lub Hoobkas qub hauv Zibo, Shandong raug nplua 1.8 lab rau qhov ua dhau tus qauv ntawm cov pa roj carbon dioxide rau lub cub tawg. Tus thawj coj luag ntxhi: "Cov nqi tiv thaiv ib puag ncig noj cov txiaj ntsig, tab sis yog tias koj tsis teeb tsa cov khoom siv tshiab, koj yuav tsum kaw!" 8 Thaum cov neeg siv khoom hauv qab pib xav tau daim ntawv pov thawj carbon footprint, lub sijhawm ntawm kev tsim khoom ntau tau nkag mus rau hauv kev suav rov qab.
2. Kev tshawb pom tshiab txog thev naus laus zis: Plaub qhov kev sib ntaus sib tua tab tom pib
(1) Kev npaj Nanoscale: kev sib ntaus sib tua kom tig "micro hmoov" mus rau hauv "hmoov zoo"
Kev sib tw loj ntawm cov khoom me me: Cov tuam txhab ua lag luam tau ua tiav kev tsim cov hmoov me me hauv qab 200 nanometers, uas tsuas yog ib lub voj voog loj dua li tus kab mob coronavirus tshiab (kwv yees li 100 nanometers).
Kev tshawb pom thev naus laus zis dispersion: Hanshou Jincheng Company txoj kev faib tawm hydraulic sedimentation daws qhov teeb meem ntawm cov khoom me me los ntawm kev ntxiv cov khoom sib xyaw dispersant, compressing qhov loj me ntawm cov khoom sib xyaw ntawm tib pawg ntawm cov khoom los ntawm ± 30% mus rau hauv ± 5%.
Kev tswj hwm morphology: Sphericalization tso cai rau micro hmoov dov txhuam los hloov qhov swb txhuam, thiab qhov kev puas tsuaj polishing poob qis 70%.6. Ib tug engineer los ntawm ib lub tuam txhab Nyiv Pooj tau piav qhia nws li: "Nws zoo li hloov cov xuab zeb nrog cov hlaws iav, thiab qhov feem pua ntawm kev khawb ntuj tsim poob qis."
(2) Kev hloov pauv sodium tsawg: Kev huv huv txiav txim siab tus nqi
Kev lag luam semiconductor ntxub cov sodium ions - qhov sodium uas muaj kuab paug loj npaum li ib lub noob ntsev tuaj yeem rhuav tshem tag nrho cov wafer. Hmoov corundum dawb uas muaj sodium tsawg (Na2O cov ntsiab lus ≤ 0.02%) tau dhau los ua khoom lag luam kub:
Kev txhim kho thev naus laus zis arc melting: Kev tiv thaiv roj inert melting tau txais yuav, thiab tus nqi sodium volatilization nce ntxiv 40%.
Txoj kev npaj hloov cov khoom siv raw: Kaolin siv los hloov bauxite, thiab cov ntsiab lus sodium raug txo qis ntau dua 60%.
Txawm hais tias tus nqi ntawm cov khoom no siab dua 3 npaug ntawm cov hmoov ib txwm muaj, nws tsis muaj txaus. Cov kab sodium qis uas nyuam qhuav muab tso rau hauv kev tsim khoom hauv lub Hoobkas hauv Jiangxi muaj cov xaj kom txog rau xyoo 2026.
(3)Kev tsim khoom ntsuab: kev txawj ntse yuam los ntawm kev tiv thaiv ib puag ncig
Kev siv cov khoom siv raw rov ua dua tshiab: Kev siv tshuab rov ua dua tshiab ntawm cov log sib tsoo pov tseg tuaj yeem ua rau kom muaj kev siv cov hmoov pov tseg ntau dua 85%, txo tus nqi los ntawm 4,000 yuan ib tuj
Kev hloov pauv ntawm cov txheej txheem: Cov txheej txheem ua hmoov qhuav hloov pauv tag nrho cov txheej txheem ntub dej, thiab cov dej khib nyiab tso tawm raug txo kom xoom. Henan cov tuam txhab tau tsim cov txheej txheem rov qab siv cua sov pov tseg, thiab kev siv hluav taws xob tau poob qis 35%.
Kev Hloov Pauv Cov Khib Nyhiab: Ib lub Hoobkas hauv Liaocheng, xeev Shandong tau hloov cov khib nyiab slag mus ua cov khoom siv hauv tsev uas tiv taus hluav taws, uas tau tsim 2 lab yuan hauv cov nyiaj tau los txhua xyoo. Tus thawj coj tau tso dag tias: "Ua ntej, kev tiv thaiv ib puag ncig yog ib txoj hauv kev los yuav kev nyab xeeb, tab sis tam sim no nws yog ib txoj hauv kev tshiab los khwv tau nyiaj."
(4) Kev tsim khoom ntse: kev dhia ceev ceev raws li cov ntaub ntawv
Hauv lub rooj cob qhia digital ntawm Zhengzhou Xinli, lub vijtsam loj qhia txog qhov nkhaus faib cov khoom me me ntawm cov hmoov me me hauv lub sijhawm tiag tiag. "Lub kaw lus AI sorting system tuaj yeem hloov kho cov cua ntws, yog li ntawd tus nqi tsim nyog ntawm cov khoom nce ntxiv los ntawm 82% mus rau 98%. " Tus thawj coj kev tshaj lij taw tes rau cov khoom siv khiav thiab hais tias 6. Kev saib xyuas online ntawm lub tshuab ntsuas qhov loj me ntawm cov khoom me me laser ua ke nrog cov txheej txheem kev kawm tshuab tuaj yeem ua tiav cov lus taw qhia theem ob ntawm kev hloov pauv zoo, hais lus zoo rau hom "tom qab kev tshuaj xyuas" ib txwm muaj.
3. Kev sib ntaus sib tua yav tom ntej: kev hloov pauv zoo nkauj los ntawm cov log sib tsoo mus rau cov chips
Qhov tom ntej "txoj kev kub"ntawm cov hmoov av dawb corundum qhib:
Kev ntim khoom semiconductor: siv rau kev ua kom nyias thiab txhuam cov silicon wafer, nrog rau kev thov thoob ntiaj teb txhua xyoo ntau dua 25%
Lub zog tshiab: ua cov khoom siv roj teeb lithium separator, txhim kho kev tiv taus cua sov thiab kev coj ua ion
Biomedical: Nano-polishing ntawm cov hniav ceramic restorations, nrog rau qhov yuav tsum tau ua kom raug ntawm 0.1 micron
Kev hloov pauv ntawm cov hmoov av dawb corundum yog ib qho me me ntawm Tuam Tshoj txoj kev txhim kho kev tsim khoom. Thaum lub Hoobkas qub hauv Zibo siv 3D luam ntawv los tsim kho dua tshiab lub tshav pob ntawm lub qhov cub calcining, thiab thaum pab pawg los ntawm Suav Academy of Sciences cog cov alumina microspheres ib leeg-siv lead ua hauv chav kuaj, qhov tshwm sim ntawm "kev ua tsov rog micrometer" no tsis tau txiav txim siab los ntawm lub peev xwm tsim khoom tam sim no, tab sis los ntawm leej twg tuaj yeem txhais lub hauv paus ntawm kev tsim khoom yav tom ntej nrog nanometer precision.
