Hauv kev tsim khoom raug, kev sim tshawb fawb thiab lwm yam kev xav tau ntawm thaj chaw, qhov tseeb static pressure air floating platform ua lub luag haujlwm tseem ceeb. Kev xaiv lub hauv paus platform, zoo li kev tso lub hauv paus rau lub tsev, muaj feem cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub platform. Granite precision base thiab mineral casting base ua ob qho kev xaiv nrov, txhua tus muaj nws tus kheej qhov zoo, cov hauv qab no yog kev sib piv ntxaws rau koj.
Kev Ruaj Ntseg: Qhov sib txawv ntawm kev siv lead ua los ntawm ntuj thiab kev sib xyaw ua ke
Tom qab ntau lab xyoo ntawm kev hloov pauv geological, cov quartz, feldspar thiab lwm yam minerals sab hauv tau siv lead ua kom nruj, cov qauv no tuab heev thiab sib xws. Thaum muaj kev cuam tshuam sab nraud, xws li kev co los ntawm kev ua haujlwm ntawm cov khoom siv loj nyob ib puag ncig, lub hauv paus granite zoo li lub ntaub thaiv khov kho, uas tuaj yeem thaiv thiab txo qis, thiab tuaj yeem txo qhov kev co ntawm lub platform siab zoo li qub los ntawm ntau dua 80%, muab lub hauv paus khov kho thiab ruaj khov rau kev txav mus los ntawm lub platform. Hauv lub rooj cob qhia semiconductor chip manufacturing, cov txheej txheem lithography muaj qhov yuav tsum tau ua siab rau kev ruaj khov ntawm lub platform, thiab lub hauv paus granite ua kom muaj kev ua haujlwm raug ntawm cov khoom siv lithography chip, pab kom muaj kev kos duab meej ntawm cov qauv chip, thiab txhim kho cov txiaj ntsig ntawm kev tsim khoom chip.
Lub hauv paus casting mineral yog ua los ntawm cov khoom me me sib xyaw nrog cov khoom siv tshwj xeeb. Nws cov qauv sab hauv yog sib xws thiab nws muaj qee yam ntxwv ntawm kev co. Thaum cuam tshuam nrog kev co dav dav, nws tuaj yeem muab qhov chaw ua haujlwm ruaj khov rau lub platform. Txawm li cas los xij, thaum muaj kev co siab thiab kev co tas mus li, lub peev xwm txo kev co ntawm cov mineral casting base tsis txaus me ntsis piv rau granite base, uas yuav ua rau muaj kev hloov pauv me ntsis ntawm kev txav mus los ntawm platform thiab cuam tshuam rau qhov tseeb ntawm kev ua haujlwm ultra-precision.
Kev khaws cia qhov tseeb: qhov sib npaug ntawm cov txiaj ntsig ntuj thiab kev tswj hwm dag ntawm kev nthuav dav qis
Granite paub txog nws cov coefficient qis heev ntawm thermal expansion, feem ntau yog 5-7 × 10⁻⁶ / ℃. Nyob rau hauv ib puag ncig ntawm qhov kub thiab txias hloov pauv, qhov loj ntawm lub granite precision base hloov me ntsis. Hauv thaj chaw ntawm astronomy, lub precision static pressure air float platform rau kev kho kom zoo ntawm lub lens telescope yog paired nrog lub granite base, txawm tias qhov sib txawv ntawm qhov kub thiab txias 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 submicron, pab cov kws tshawb fawb txog hnub qub kom ntes tau qhov kev hloov pauv me me ntawm cov cev ntuj nyob deb.
Hauv kev tsim cov qauv ntawm cov ntaub ntawv casting minerals, cov yam ntxwv thermal expansion tuaj yeem ua kom zoo dua thiab tswj tau, thiab cov coefficient ntawm thermal expansion tuaj yeem ze rau lossis zoo dua li granite los ntawm kev kho qhov sib piv ntawm cov minerals thiab binders. Hauv qee qhov kub-sensitive, high-precision ntsuas cov khoom siv, lub hauv paus minerals casting tuaj yeem tswj tau qhov loj me ruaj khov thaum qhov kub hloov pauv, ua kom ntseeg tau qhov tseeb ntawm kev txav mus los ntawm lub platform. Txawm li cas los xij, lub hauv paus casting minerals raug cuam tshuam los ntawm cov yam xws li kev laus ntawm cov binder, thiab qhov kev ruaj khov ntev mus ntev yuav tsum tau soj ntsuam ntxiv.
Durability: Cov yam ntxwv ntawm cov pob zeb ntuj tsim uas muaj zog thiab cov khoom siv sib xyaw uas tiv taus qaug zog
Granite qhov nyuaj yog siab, Mohs hardness tuaj yeem ncav cuag 6-7, nrog kev tiv thaiv zoo hnav. Hauv cov khoom siv science laboratory, lub platform uas siv ntau zaus precision static pressure air float, nws lub hauv paus granite tuaj yeem tiv taus kev sib txhuam mus sij hawm ntev, piv rau lub hauv paus ib txwm muaj, tuaj yeem ntev lub voj voog txij nkawm ntawm lub platform ntau dua 50%, txo cov nqi txij nkawm khoom siv, thiab xyuas kom meej tias kev ua haujlwm tshawb fawb txuas ntxiv mus. Txawm li cas los xij, cov khoom siv granite yog qhov tsis yooj yim tawg thiab yooj yim tawg thaum raug cuam tshuam tsis raug.
Lub hauv paus casting mineral muaj cov yam ntxwv zoo heev tiv thaiv kev qaug zog, uas tuaj yeem tiv taus kev puas tsuaj ntawm kev qaug zog thiab tswj kev ruaj khov ntawm cov qauv thaum lub sijhawm ntev ntawm kev txav mus los ntawm qhov tseeb static siab cua ntab platform. Tib lub sijhawm, nws muaj qee qhov kev tiv thaiv rau cov tshuaj lom neeg dav dav, thiab nyob rau hauv ib puag ncig nrog me ntsis kev pheej hmoo ntawm kev xeb tshuaj lom neeg, nws ruaj khov dua li lub hauv paus granite. Txawm li cas los xij, nyob rau hauv ib puag ncig hnyav xws li cov av noo siab, cov binder hauv lub hauv paus casting mineral tuaj yeem cuam tshuam, txo nws cov durability.
Tus nqi tsim khoom thiab qhov nyuaj ntawm kev ua: Cov teeb meem ntawm pob zeb ntuj thiab cov kev txwv ntawm kev ua cov khoom cuav
Kev khawb av thiab kev thauj mus los ntawm cov khoom siv granite yog qhov nyuaj, thiab kev ua cov txheej txheem xav tau cov cuab yeej 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 khoom siv casting mineral xav tau ib lub pwm thiab cov txheej txheem tshwj xeeb, thiab tus nqi tsim pwm thaum ntxov yog siab, tab sis thaum lub pwm tau tsim, tuaj yeem ua tiav ntau lawm thiab tus nqi ib chav tuaj yeem txo qis. Nws cov txheej txheem ua tiav yooj yim piv rau granite, thiab nws tuaj yeem ua tiav cov kev xav tau siab dua los ntawm kev siv tshuab, thiab muaj peev xwm tsim nyog hauv cov xwm txheej loj.
