Lub luag haujlwm hloov pauv ntawm alumina hmoov hauv kev lag luam abrasive
Cov neeg uas tau ua hauj lwm hauv kev cob qhia abrasive paub tias nws yog ib qho mob taub hau los daws cov khoom siv tawv tawv - cov nplaim taws los ntawm lub log sib tsoo, khawb ntawm qhov chaw ua haujlwm, thiab qhov poob ntawm cov txiaj ntsig. Tus thawj lub ntsej muag yog tsaus dua li hauv qab ntawm lub lauj kaub. Kom txog rau thaum cov hmoov dawb ntawmalumina hmoovrushed mus rau hauv lub battlefield, nws dragged lub abrasive kev lag luam mus rau ib tug tshiab era. Niaj hnub no, cia peb tham txog vim li cas qhov no tau dhau los ua "tus cawm seej" ntawm kev lag luam niaj hnub no!
1. Muaj txuj ci: "hexagonal warrior" hauv kev lag luam abrasive
Alumina hmoov yug los ua ib tug neeg tawv tawv uas noj lub tais no. Peb hard-core zog ncaj qha tsoo nws cov phooj ywg:
Hardness yog siab: Mohs hardness pib ntawm 9.0, thib ob tsuas yog pob zeb diamond. Lub tuam txhab cuab yeej cuab tam hauv Guangdong ntsuas: Thaum txiav cov hlau nrawm, lub neej ntawm alumina sib tsoo lub log yog 3 npaug ntawm cov khoom siv zoo tib yam. Tus tswv qub Huang tau hais nrog luam yeeb hauv nws lub qhov ncauj: "Kuv tau hloov lub log sib tsoo peb zaug thaum txiav cov hlau alloy, tab sis tam sim no kuv tuaj yeem ua tau txhua txoj hauv kev yam tsis ua pa!"
Zoo kawg purity: 99.6% α-Al₂O₃ cov ntsiab lus, hlau impurities yog suppressed tsawg dua 0.01%. Shanghai Semiconductor Factory raug kev txom nyem: siv hlau-muaj abrasives rau polish wafers, qhov saum npoo zoo li pockmarks tom qab peb lub hlis; siv alumina hmoov los kho, nws tsis hloov xim txawm nyob rau hauv cov kua qaub da dej.
Thermal stability zoo li qub dev: melting point 2050 ℃, thermal expansion coefficient tsawg li 4.8 × 10⁻⁶ / ℃. Lub foob pob hluav taws nozzle Hoobkas hauv Qingdao siv nws los zom cov hlau kub kub, thiab qhov hloov pauv loj hauv qab 1500 ℃ ib puag ncig tsawg dua 6 npaug ntawm txoj kab uas hla ntawm cov plaub hau.
Dab tsi yog qhov zoo tshaj plaws yog tias nws tuaj yeem hloov nws cov duab 72 zaug - los ntawm micron-theem ca cov khoom mus rau nano-theem kheej kheej hmoov, nws tuaj yeem hloov pauv lossis tiaj tus raws li koj xav tau, thiab nws tshwj xeeb tsim los kho txhua yam kev tsis mloog lus!
2. Revolutionary scene: "Nuclear explosion-level performance" nyob rau hauv peb qhov kev sib ntaus sib tua loj
Semiconductor Rhiav: Nano-theem paj ntaub txuj ci
Silicon wafer polishing: Flat alumina micropowder skims hla saum npoo ntawm silicon wafer zoo li skating, thiab khawb tus nqi poob los ntawm 70% los ntawm zawv zawg sib tsoo es tsis txhob tsoo tsoos. Tus tswv ntawm SMIC tau hais tias: "Qhov haujlwm no yog qhov muag heev dua li paj ntaub!"
Silicon carbide nti: Nano-alumina polishing kua laum rau hauv cov nti sib txawv, thiab cov cua sov dissipation efficiency yog txhim kho los ntawm cov nyhuv quantum, thiab cov txiaj ntsig tau nce mus txog 99.98%. Tus kws ua haujlwm ua haujlwm tau patted daim duab electron microscope thiab khav hais tias: "Qhov kev txiav txim siab no siab heev uas txawm tias yoov tshaj cum sawv ntawm nws yuav tau ua qhov sib cais!"
Sapphire substrate: Submicron alumina polishes LED substrate rau Ra <0.3nm, uas yog smoother dua daim iav. Tus thawj coj ntawm Dongguan Optoelectronics Factory tau hais zoo siab tias: "Tam sim no peb tab tom tsim iPhone lo ntsiab muag, thiab Apple cov neeg soj ntsuam nrhiav tsis tau qhov txhaum rau lawv!"
Automotive Rhiav: tus nqi killer online
Aerospace: cov kws tshaj lij kev sib tw heev
Turbine hniav mortise thiab tenon ua:Alumina sib tsoo logua haujlwm ntawm nickel-based alloy, thiab nws tuaj yeem tiv taus 100 teev yam tsis muaj hmoov poob ntawm qhov ceev ntawm 2200 rpm. Tus neeg tsav tsheb xeem Lao Li ntsia ntawm qhov kev tshuaj ntsuam xyuas thiab qw: "Nrog qhov hnav tsis kam, txawm tias Musk yuav tsum tau haus luam yeeb!"
Rocket nozzle puab phab ntsa polishing: Nano-coated alumina hmoov txo cov roughness rau Ra0.01μm, thiab roj efficiency yog txhim kho los ntawm 8%. Tus thawj kws ua choj tau hais nrog lub qhov muag liab: "Cov 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 "cuam tshuam caj dab" mus rau "arm wrestling"
Cov alumina abrasives hauv tsev siv los ua "zaj dab neeg tu siab" - kev hnav tsis zoo, cov khoom tsis ruaj khov, nano hmoov agglomeration zoo li pob khaus kua zaub, thiab lub khw high-end tau monopolized los ntawm American thiab Japanese tuam txhab 13. Tab sis nthwv dej ntawm semiconductor localization yuam Jedi counterattack:
Purity nres: Ib lub Hoobkas hauv Luoyang tau tsim lub cub hluav taws xob ntse tswj qhov kub thiab txias, thiab α theem hloov pauv tau mus txog 99.95%, thiab qhov purity yog sib npaug rau Nyiv Showa Denko.
Particle loj metaphysics: Zhejiang tuam txhab uas muag siv AI turbine classifiers los tswj cov particle loj faib nyob rau hauv ± 0.1μm. Cov neeg siv khoom Kauslim tau poob lawv lub puab tsaig thaum tshuaj xyuas cov khoom: "Cov ntaub ntawv no yog qhov tseeb dua li lub tshuab ntes!"
Khib nyiab rebirth: Shandong puag crushes thiab refines pov tsegsib tsoo log, thiab qhov sib xyaw ua ke yog txo mus rau 30%, thiab tus nqi raug txo los ntawm 40%. Tus thawj coj ntawm lub rooj cob qhia, Lao Zhou, luag thiab thuam tias: "Cov khib nyiab uas tau muab pov tseg thaum poob tam sim no muaj nqis dua li cov khoom tshiab!"
4.Qhov kev sib ntaus sib tua yav tom ntej: peb lub ntsiab lus tseem ceeb ruaj khov
Nano-theem tswj: Hefei lub chaw kuaj mob tau los nrog cov thev naus laus zis dub - atomic txheej deposition thev naus laus zis los tso "cov cuab yeej" rau ntawm cov hmoov micro thiab daws qhov teeb meem ntawm agglomeration. Tus kws tshawb fawb tau tuav tus qauv thiab khav hais tias: "Tam sim no chip polishing smoother dua waxing!"
Green Revolution: Cov nroj tsuag Chongqing siv cov pov tseg cov kua qaub rov qab los txo qhov tso tawm ntawm 300 tons ntawm cov khib nyiab pov tseg txhua xyoo. Cov neeg los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Ib puag ncig tau tuaj xyuas thiab muab tus ntiv tes xoo: "Koj yuav tso cov dej phwj tuaj tawm!"
Cov cuab yeej sib tsoo ntse: Lub Hoobkas hauv Zhengzhou tau teeb tsa lub siab ntsuas ntawm lub log sib tsoo los kho cov kev sib tsoo hauv lub sijhawm. Xiao Liu, tus kws tshaj lij yug hauv xyoo 1990, ntaus rau ntawm cov keyboard thiab khav hais tias: "Tam sim no kho qhov tsis yooj yim dua li kev ua si, thiab cov txiaj ntsig tau mus txog 99.8%!"
