Lub luag haujlwm hloov pauv ntawm alumina hmoov hauv kev lag luam abrasive
Cov neeg uas tau ua haujlwm hauv cov chaw ua haujlwm abrasive paub tias nws yog ib qho mob taub hau rau kev daws cov khoom siv uas muaj zog heev - cov hluav taws xob los ntawm lub log sib tsoo, khawb ntawm qhov chaw ua haujlwm, thiab qhov poob qis ntawm cov txiaj ntsig. Lub ntsej muag ntawm tus thawj coj tsaus dua li hauv qab ntawm lub lauj kaub. Txog thaum cov hmoov dawb ntawmalumina hmoovraug thawb mus rau hauv kev sib ntaus sib tua, nws rub kev lag luam abrasive mus rau hauv lub sijhawm tshiab. Niaj hnub no, cia peb tham txog vim li cas qhov no tau dhau los ua "tus cawm seej ntawm kev sib tsoo" ntawm kev lag luam niaj hnub no!
1. Muaj peev xwm: "tus tub rog hexagonal" hauv kev lag luam abrasive
Hmoov alumina yug los ua ib tug txiv neej tawv ncauj uas noj lub tais mov no. Peb yam khoom tawv ncauj uas ncaj qha rhuav tshem nws cov phooj ywg:
Qhov nyuaj yog siab: Mohs hardness pib ntawm 9.0, thib ob tsuas yog pob zeb diamond. Lub Hoobkas cuab yeej hauv Guangdong ntsuas: Thaum txiav cov hlau ceev ceev, lub neej ntawm alumina sib tsoo log yog 3 npaug ntawm cov abrasives ib txwm muaj. Tus tswv qub Huang hais nrog ib tug luam yeeb hauv nws lub qhov ncauj: "Kuv siv los hloov lub log sib tsoo peb zaug thaum txiav cov hlau alloy, tab sis tam sim no kuv tuaj yeem ua nws tag nrho txoj kev yam tsis tau ua pa!"
Kev ntshiab zoo kawg nkaus: 99.6% α-Al₂O₃ cov ntsiab lus, cov hlau tsis huv raug tswj kom tsawg dua 0.01%. Shanghai Semiconductor Hoobkas tau raug kev poob: siv cov hlau-muaj abrasives los txhuam cov wafers, qhov chaw zoo li pockmarks tom qab peb lub hlis; siv alumina hmoov los kho, nws tsis hloov xim txawm tias nyob rau hauv acid da dej.
Kev ruaj khov ntawm thermal zoo li tus dev laus: qhov chaw yaj 2050 ℃, qhov coefficient ntawm thermal expansion qis li 4.8 × 10⁻⁶ / ℃. Lub Hoobkas rocket nozzle hauv Qingdao siv nws los sib tsoo cov hlau kub siab, thiab qhov hloov pauv loj hauv qab 1500 ℃ ib puag ncig yog tsawg dua 6 npaug ntawm txoj kab uas hla ntawm cov plaub hau.
Qhov zoo kawg nkaus ntxiv yog tias nws tuaj yeem hloov nws cov duab 72 zaug - los ntawm cov khoom me me hauv micron mus rau cov hmoov me me hauv nano, nws tuaj yeem ua puag ncig lossis tiaj tus raws li koj xav tau, thiab nws tau tsim tshwj xeeb los kho txhua yam kev tsis mloog lus!
2. Qhov xwm txheej hloov pauv: "Kev ua tau zoo ntawm kev tawg nuclear" hauv peb qhov chaw sib ntaus sib tua loj
Kev cob qhia semiconductor: Kev txawj xaws paj ntaub theem Nano
Kev txhuam silicon wafer: Cov hmoov alumina tiaj tiaj hla qhov chaw ntawm silicon wafer zoo li kev caij skating, thiab qhov khawb poob qis 70% los ntawm kev sib tsoo es tsis txhob dov ib txwm muaj. Tus tswv ntawm SMIC tau qw hais tias: "Txoj haujlwm no zoo dua li paj ntaub!"
Silicon carbide chip: Nano-alumina polishing kua drills rau hauv qhov sib txawv ntawm cov chip, thiab qhov ua kom sov dissipation efficiency tau zoo dua los ntawm cov nyhuv quantum tunnel, thiab cov txiaj ntsig nce mus txog 99.98%. Tus kws ua haujlwm project patched daim duab electron microscope thiab khav theeb: "Qhov kev ua tau zoo no siab heev uas txawm tias tus yoov tshaj cum sawv ntawm nws yuav tsum ua qhov sib cais!"
Sapphire substrate: Submicron alumina txhuam cov LED substrate rau Ra <0.3nm, uas yog smoother dua li daim iav. Tus thawj coj ntawm Dongguan Optoelectronics Factory hais zoo siab tias: "Tam sim no peb tab tom ua iPhone lenses, thiab Apple cov neeg soj ntsuam tsis tuaj yeem nrhiav qhov txhaum nrog lawv!"
Lub Hoobkas Muag Tsheb: tus nqi pheej yig hauv online
Aerospace: cov kws tshaj lij kev sib tw hnyav heev
Kev ua cov hniav turbine mortise thiab tenon:Alumina sib tsoo logua haujlwm ntawm cov hlau nickel-based alloy, thiab nws tuaj yeem tiv taus 100 teev yam tsis poob hmoov ntawm qhov ceev ntawm 2200 rpm. Tus neeg tsav tsheb sim Lao Li ntsia ntawm lub vijtsam saib xyuas thiab qw tias: "Nrog rau qhov kev tiv thaiv kev hnav no, txawm tias Musk yuav tsum hla luam yeeb!"
Kev txhuam sab hauv phab ntsa ntawm lub foob pob hluav taws: Cov hmoov alumina uas tau txheej nrog nano txo qhov roughness mus rau Ra0.01μm, thiab kev siv roj tau zoo dua 8%. Tus thawj coj ua haujlwm hais nrog lub qhov muag liab tias: "Ib yam khoom no ib leeg tuaj yeem txuag tau peb tons roj txhua xyoo!"
3. Kev tawm tsam ntawm kev tsim khoom hauv tsev: los ntawm "caj dab daig" mus rau "kev sib tw caj npab"
Cov khoom siv alumina abrasives hauv tsev siv los ua "zaj dab neeg tu siab" - tsis zoo hnav tsis kam, cov khoom tsis ruaj khov, nano hmoov sib sau ua ke zoo li kua zaub pob khaus, thiab kev ua lag luam siab tau raug tswj hwm los ntawm cov tuam txhab Asmeskas thiab Nyiv Pooj13. Tab sis nthwv dej ntawm semiconductor localization yuam kom Jedi tawm tsam:
Kev tawm tsam purity: Ib lub Hoobkas hauv Luoyang tau tsim lub tshuab hluav taws xob arc furnace ntse tswj qhov kub thiab txias, thiab qhov hloov pauv theem α tau mus txog 99.95%, thiab qhov purity yog sib npaug rau Nyiv Showa Denko.
Kev ntsuas qhov loj ntawm cov khoom me me: Cov tuam txhab Zhejiang siv AI turbine classifiers los tswj qhov faib tawm ntawm cov khoom me me hauv ± 0.1μm. Cov neeg siv khoom Kauslim tau poob lawv lub puab tsaig thaum tshuaj xyuas cov khoom: "Cov ntaub ntawv no raug dua li lub tshuab ntes!"
Kev rov qab yug dua tshiab ntawm cov khib nyiab: Shandong lub hauv paus tsoo thiab rov ua kom cov khib nyiab zoo duacov log sib tsoo, thiab qhov sib xyaw ua ke raug txo kom txog 30%, thiab tus nqi raug txo los ntawm 40%. Tus thawj coj ntawm lub rooj cob qhia, Lao Zhou, luag thiab cem tias: "Cov khib nyiab uas tau muab pov tseg tsis tau zoo tam sim no muaj nqis dua li cov ntaub ntawv tshiab!"
4. Lub tshav rog yav tom ntej: peb qhov kev hloov pauv tseem ceeb yog ruaj khov
Kev tswj hwm theem nano: Hefei chav kuaj mob tau tsim cov thev naus laus zis dub - thev naus laus zis tso cov txheej txheem atomic los muab "armor" rau ntawm cov hmoov me me thiab daws qhov teeb meem ntawm kev sib sau ua ke. Tus kws tshawb fawb tau tsa cov qauv thiab khav theeb tias: "Tam sim no kev txhuam cov chip du dua li kev siv waxing!"
Kev Hloov Pauv Ntsuab: Lub Hoobkas Chongqing siv lub tshuab rov qab siv cov kua qaub pov tseg los txo qhov kev tso tawm ntawm 300 tons ntawm cov khib nyiab phom sij txhua xyoo. Cov neeg los ntawm Lub Chaw Tiv Thaiv Ib Puag Ncig tau tuaj xyuas thiab qhuas: "Koj yuav tso lub Hoobkas kho dej phwj tawm!"
Cov cuab yeej sib tsoo ntse: Ib lub Hoobkas hauv Zhengzhou tau teeb tsa lub ntsuas siab ntawm lub log sib tsoo kom kho cov kev sib tsoo hauv lub sijhawm tiag tiag. Xiao Liu, tus kws tshaj lij yug hauv xyoo 1990, ntaus ntawv rau ntawm lub keyboard thiab khav theeb tias: "Tam sim no kev kho cov kev sib tsoo yooj yim dua li kev ua si, thiab tus nqi tau mus txog 99.8%!"
