Hauv thaj chaw ntawm kev tswj hwm kev txav mus los uas muaj qhov tseeb heev, qhov kev ua tau zoo ntawm cov khoom siv txav mus los uas muaj qhov tseeb heev nyob ntawm cov yam ntxwv ntawm nws lub hauv paus. Lub hauv paus granite precision thiab lub hauv paus ceramic ua ob qho kev xaiv siab, txhua tus muaj qhov zoo tshwj xeeb, hauv kev ruaj khov, kev saib xyuas qhov tseeb, kev ruaj khov thiab lwm yam tseem ceeb muaj qhov sib txawv pom tseeb.
Kev Ruaj Ntseg: qhov sib zog ntawm ntuj thiab cuav
Granite tsim tom qab lub sijhawm geological ntev, cov qauv sab hauv yog ntom thiab sib xws, thiab cov zaub mov xws li quartz thiab feldspar tau sib txuas ze. Thaum muaj kev cuam tshuam sab nraud, xws li kev co los ntawm kev ua haujlwm ntawm cov khoom siv loj hauv lub chaw ua haujlwm, lub hauv paus granite tuaj yeem thaiv thiab ua kom zoo nrog nws cov qauv siv lead ua ke, uas tuaj yeem txo qhov kev co ntawm lub zog ntawm lub zog txav mus los ultra-precision xa mus rau lub ntab cua los ntawm ntau dua 80%, muab lub hauv paus ua haujlwm ruaj khov rau lub module kom ntseeg tau tias nws txav mus zoo hauv cov txheej txheem ntawm kev ua tiav siab lossis kev tshawb pom.
Lub hauv paus ceramic yog tsim los ntawm cov txheej txheem tsim khoom siab heev, thiab nws cov qauv sab hauv kuj zoo heev. Lub microstructure ntawm qee cov khoom siv ceramic ua haujlwm siab yuav luag zoo meej, uas tuaj yeem tsim cov nyhuv damping zoo rau kev co. Hauv qee cov khoom siv tshuaj xyuas qhov muag uas rhiab heev rau kev co, lub hauv paus ceramic tuaj yeem tswj hwm kev cuam tshuam kev co hauv qhov me me kom ntseeg tau tias muaj kev txav mus los ntawm qhov tseeb ntawm cov qauv txav mus los ntawm huab cua ntab, tab sis teb rau qhov loj thiab kev co siab, nws qhov kev ruaj khov tag nrho yog qis dua me ntsis ntawm lub hauv paus granite.
Kev khaws cia qhov tseeb: qhov zoo ntawm qhov nthuav dav tsawg thiab qhov xav tsis thoob ntawm kev ruaj khov kub siab
Granite paub txog nws cov coefficient qis heev ntawm thermal expansion, feem ntau ntawm 5-7 × 10⁻⁶ / ℃. Hauv qhov kub thiab txias hloov pauv, qhov loj ntawm lub granite precision base hloov me ntsis. Piv txwv li, hauv thaj chaw ntawm astronomy, lub ultra-precision motion module rau kev kho kom zoo ntawm lub lens telescope yog paired nrog lub granite base, txawm tias nyob rau hauv ib puag ncig uas qhov sib txawv ntawm kub ntawm hnub thiab hmo ntuj yog qhov tseem ceeb, nws tuaj yeem ua kom ntseeg tau tias qhov tseeb ntawm lub lens yog khaws cia ntawm qib sub-micron, pab cov kws tshawb fawb txog hnub qub kom ntes tau qhov kev hloov pauv me me ntawm cov cev ntuj ceeb tsheej nyob deb.
Cov ntaub ntawv ceramic kuj ua tau zoo hauv qhov kub siab ruaj khov thiab cov yam ntxwv nthuav dav tsawg, thiab cov coefficient ntawm thermal nthuav dav ntawm qee cov ceramics tshwj xeeb tuaj yeem qis li ze rau xoom. Nyob rau hauv qhov xwm txheej ntawm qhov kub siab lossis hloov pauv kub sai, lub hauv paus ceramic tuaj yeem tswj tau qhov loj me kom ntseeg tau tias qhov tseeb ntawm kev txav mus los ntawm ultra-precision motion module ntawm huab cua ntab tsis cuam tshuam. Hauv cov txheej txheem lithography ntawm semiconductor chip manufacturing, cov khoom siv lithography yuav tsum txuas ntxiv ua haujlwm hauv qhov chaw muaj tseeb siab, thiab lub hauv paus ceramic tuaj yeem tswj tau qhov tseeb ntawm qhov chaw ntawm lub module hauv qhov chaw kub siab uas tsim los ntawm cov khoom siv, ua tau raws li cov kev cai nruj ntawm kev tsim khoom nti rau qhov tseeb nanoscale.
Kev ruaj khov: Kev nyuaj siab ntawm cov pob zeb ntuj thiab cov khoom siv hluavtaws uas tiv taus corrosion
Granite qhov nyuaj yog siab, Mohs hardness tuaj yeem ncav cuag 6-7, nrog kev tiv thaiv zoo. Hauv chav kuaj khoom siv, feem ntau siv air float ultra-precision motion module, nws lub hauv paus granite tuaj yeem tiv taus kev sib txhuam ntev ntawm lub slider air float, piv nrog cov khoom siv ib txwm muaj, tuaj yeem ntev lub voj voog txij nkawm ntawm lub module ntau dua 50%, txo cov nqi kho khoom siv, kom ntseeg tau tias kev ua haujlwm tshawb fawb txuas ntxiv mus.
Cov khoom siv ceramic tsis yog tsuas yog muaj qhov nyuaj siab xwb, tab sis kuj muaj kev tiv thaiv corrosion zoo heev. Hauv qee qhov chaw ua lag luam uas muaj kev pheej hmoo ntawm kev xeb tshuaj lom neeg, xws li lub tshuab txav mus los ultra-precision ntawm lub ntab huab cua hauv cov khoom siv kuaj tshuaj lom neeg, lub hauv paus ceramic tuaj yeem tiv taus kev yaig ntawm cov pa roj lossis kua corrosive, tswj kev ncaj ncees ntawm qhov chaw thiab cov khoom siv kho tshuab ntev, thiab nws lub zog ruaj khov zoo dua li lub hauv paus granite hauv qee qhov chaw nyuaj.
Tus nqi tsim khoom thiab qhov nyuaj ntawm kev ua: kev khawb av thiab kev ua cov pob zeb ntuj thiab qhov kev txwv ntawm kev tsim khoom cuav
Cov txheej txheem khawb thiab thauj cov khoom siv granite yog qhov nyuaj, thiab kev ua cov txheej txheem xav tau cov khoom siv thiab thev naus laus zis siab heev. Vim nws qhov nyuaj thiab brittleness siab, nws yooj yim kom muaj teeb meem xws li ntug tawg thiab tawg hauv kev txiav, sib tsoo, polishing thiab lwm yam txheej txheem, thiab tus nqi pov tseg yog qhov siab, ua rau cov nqi tsim khoom siab.
Kev tsim cov hauv paus ceramic vam khom kev tsim kho tshiab thiab kev siv tshuab ua kom raug, txij li kev npaj cov khoom siv raw, molding mus rau sintering, txhua kauj ruam xav tau kev tswj hwm meej. Kev nqis peev thaum ntxov hauv kev tsim kho thiab tsim cov hauv paus ceramic ua tau zoo yog qhov loj heev thiab qhov kev siv tshuab siab, tab sis thaum nws ua tiav kev tsim khoom loj, tus nqi yuav tsum tau tswj hwm zoo, thiab nws muaj peev xwm tsim nyog rau cov ntawv thov siab.
Zuag qhia tag nrho, cov granite precision bases ua tau zoo hauv kev ruaj khov tag nrho thiab kev ruaj khov ib txwm muaj, thaum cov ceramic bases muaj qhov zoo tshwj xeeb hauv kev hloov pauv qhov kub thiab txias heev thiab kev tiv taus corrosion. Kev xaiv lub base yuav tsum raws li qhov xwm txheej ntawm daim ntawv thov tshwj xeeb, cov xwm txheej ib puag ncig thiab cov nqi ntawm cov air float ultra-precision motion module.
