Cov Ntawv Thov Tseem Ceeb thiab Tus Nqi Lag Luam ntawm Ultra-Precision / Ultra-Fine Diamond Micropowder
Cov hmoov pob zeb diamond uas muaj qhov tseeb thiab zoo heev, ua cov khoom siv abrasive uas nyuaj tshaj plaws, ntse tshaj plaws, thiab tswj tau qhov loj me ntawm cov khoom me me uas muaj tam sim no, tab tom dhau los ua cov khoom siv tseem ceeb hauv kev tsim khoom raug. Nrog rau qhov xav tau ntau ntxiv rau qhov zoo ntawm qhov chaw, kev ua tiav qhov tseeb, thiab kev ntseeg siab ntawm cov khoom siv los ntawm kev lag luam xws li optics, electronics, semiconductors, thiab lub zog tshiab,pob zeb diamond micropowdertab tom txav los ntawm kev sib tsoo thiab polishing ib txwm mus rau qib siab dua ultra-precision manufacturing, thiab nws daim ntawv thov scope yog txuas ntxiv nthuav dav. Cov khoom me me ntawm pob zeb diamond micropowder feem ntau yog nruab nrab ntawm 0.1–10 μm, nrog rau submicron thiab nano-sized ultrafine hmoov ua cov khoom siv tseem ceeb hauv kev tsim khoom siab heev. Lawv muaj qhov nyuaj siab heev Mohs 10, thermal conductivity siab, coefficient qis ntawm kev sib txhuam, thiab micro-cutting peev xwm tsim thaum lub sijhawm ua tiav, ua rau atomic-level nto tiav ntawm cov ntaub ntawv ua tiav. Qhov no yog qhov pom tseeb tshwj xeeb hauv theem kawg polishing ntawm optical lenses, sapphire, ceramics, laser crystals, semiconductor wafers, thiab ultrahard metals, qhov twg lawv qhia txog qhov zoo tsis tuaj yeem hloov pauv.
Hauv cov teb ntawm optics thiab lasers,hmoov pob zeb diamond ultrafinefeem ntau yog siv rau kev txhuam kom meej ntawm cov iav kho qhov muag, cov siv lead ua infrared, cov qhov rai sapphire, cov iav uas muaj kev cuam tshuam siab, thiab cov siv lead ua laser. Kev lag luam optics xav tau qhov roughness ntawm qhov chaw siab heev, feem ntau xav tau Ra < 1 nm. Cov ntug txiav ntse ntawm cov hmoov pob zeb diamond, ua haujlwm hauv hom kev puas tsuaj tsawg, txo cov khaubncaws sab nraud povtseg thiab cov kab nrib pleb me me, txhim kho kev xa hluav taws xob thiab kev ua haujlwm ntawm qhov muag. Hauv kev ua cov iav xov tooj ntawm tes sapphire, cov qhov rai infrared, cov lim dej sib txuas lus, thiab cov iav resonator laser, cov khoom siv txhuam pob zeb diamond, cov ntaub txhuam pob zeb diamond, thiab cov khoom siv pob zeb diamond yog cov khoom siv tseem ceeb. Ntxiv mus, cov hmoov ultrafine kuj siv rau hauv MRF (magnetorheological rheological polishing) thiab CMP (chemical mechanical polishing) cov txheej txheem. Los ntawm kev tswj qhov loj me ntawm cov khoom me me thiab cov txheej txheem txheej saum npoo, kev txiav sib xws thiab kev txhuam tsis zoo yog ua tiav, txhim kho kev ua haujlwm zoo thiab cov txiaj ntsig ntawm cov khoom siv kho qhov muag.
Hauv kev lag luam semiconductor thiab electronics, ultraprecision diamond hmoov yog siv rau kev sib tsoo thiab polishing ntawm silicon wafers, silicon carbide (SiC), gallium nitride (GaN), sapphire substrates, thiab compound semiconductor wafers. Nrog rau kev loj hlob sai ntawm SiC fais fab khoom siv thiab kev lag luam semiconductor tiam thib peb, qhov nyuaj thiab brittleness ntawm wafers ua rau muaj kev thov ntau dua rau kev sib tsoo consumables. Diamond micropowder tuaj yeem tshem tawm cov khoom sai sai thaum lub sijhawm sib tsoo thiab txo qhov roughness ntawm qhov chaw mus rau qib nanometer thaum lub sijhawm polishing, txo qhov puas tsuaj ntawm qhov chaw thiab yog li txhim kho cov khoom siv thiab kev ua haujlwm dissipation cua sov. Hauv kev lag luam vaj huam sib luag zaub, diamond micropowder yog siv dav rau kev polishing ultra-precision ntawm iav npog, saib iav, 3D npog iav, thiab AR / VR optical Cheebtsam. Nws cov txheej txheem ua haujlwm siab tuaj yeem ua rau lub voj voog molding luv dua, txhim kho cov khoom sib xws, thiab txhim kho cov kab ntau lawm thiab lub sijhawm voj voog.
Hauv cov teb uas muaj zog heev xws li cemented carbide, ceramics, thiab metal matrix composites, ultrafine diamond micropowder yog siv dav rau kev sib tsoo precision ntawm cov ntug cuab yeej, precision polishing ntawm pwm, kev txhim kho qhov chaw ntawm cov khoom siv aerospace, thiab precision forming. Thaum cov cuab yeej cemented carbide tuaj yeem txhim kho kev tiv thaiv kev hnav thiab txiav lub neej tom qab ntug passivation thiab polishing,pob zeb diamond micropowder tuaj yeem ua tiav qhov txiav me me thaum tswj qhov ntse, ua rau muaj qhov sib npaug thiab puag ncig microstructure ntawm ntug txiav. Hauv kev lag luam pwm precision, xws li pwm txhaj tshuaj, pwm tuag-casting, thiab pwm optical, pob zeb diamond micron hmoov polishing tuaj yeem ua tiav cov teebmeem zoo li daim iav sub-nanometer, txhim kho lub neej pwm, kev ua haujlwm demolding, thiab molding zoo. Hauv kev lag luam tsheb, aerospace, thiab cov khoom siv hluav taws xob, pob zeb diamond micron hmoov kuj tseem siv rau kev sib tsoo ultra-precision ntawm qee cov ntaub ntawv tshwj xeeb, xws li cov khoom siv turbine ceramic nyuaj, nickel-based superalloys, thiab carbon fiber composites, muab cov khoom muaj kev ntseeg siab dua thiab kev ua haujlwm ruaj khov.
Raws li cov teb thov txuas ntxiv nthuav dav, cov txheej txheem npaj ntawm ultra-precision pob zeb diamond micron hmoov kuj tseem niaj hnub hloov kho dua tshiab. Tam sim no, cov txheej txheem npaj tseem ceeb suav nrog kev sib tsoo pob zeb diamond dag zog siab, kev tawg (nanodiamond), cov txheej txheem tshuaj lom neeg, thiab cov txheej txheem hloov kho qhov chaw. Txhawm rau kom tau raws li qhov xav tau siab dua rau kev ruaj khov thiab kev ncua hauv kev lag luam optics thiab semiconductor, cov hmoov micron zoo feem ntau yog coated, xws li nrog cov hlau, inorganics, organics, thiab surfactants, yog li txhim kho kev sib kis, kev tiv thaiv cua sov, thiab kev ua tiav. Ultrafine-grained pob zeb diamond maj mam hloov cov tsooscov ntaub ntawv txhuam hniavxws li cerium oxide thiabaluminahauv cov txheej txheem CMP, txhim kho qhov tiaj tiaj thiab kev ua haujlwm zoo ntawm cov wafers thiab cov khoom siv kho qhov muag. Yav tom ntej, nrog rau kev txhim kho ntawm kev tsim khoom ntse, kev sib txuas lus quantum, cov khoom siv kho mob precision thiab cov khoom siv optoelectronic siab heev, ultra-precision diamond micro hmoov yuav txuas ntxiv nthuav nws cov ciam teb daim ntawv thov thiab dhau los ua cov khoom siv tseem ceeb hauv kev lag luam ua cov ntaub ntawv.
