Granite precision platforms tau dav siv hauv kev lag luam uas xav tau siab precision thiab ruaj khov, xws li metrology thiab kev tsim khoom. Muab lawv lub luag haujlwm tseem ceeb hauv kev tswj qhov tseeb qhov tseeb, ib lo lus nug tseem ceeb feem ntau tshwm sim: yuav ua li cas hygroscopic yog granite, thiab nws puas tuaj yeem deform nyob rau hauv ib qho chaw ntub dej? Nkag siab txog cov khoom hygroscopic ntawm granite yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov platforms no tswj lawv cov kev ruaj ntseg thiab kev ua tau zoo hauv ntau hom kev ua haujlwm.
Granite, raws li lub pob zeb ntuj, yog tsim los ntawm ntau yam minerals, xws li quartz, feldspar, thiab mica. Tsis zoo li cov ntaub ntawv xws li ntoo lossis qee yam hlau, granite muaj hygroscopicity tsawg heev. Qhov no txhais tau tias nws tsis nqus cov dej noo ntau los ntawm ib puag ncig ib puag ncig, txawm tias nyob rau hauv cov huab cua ntub. Cov qauv molecular ntawm granite, feem ntau yog tsim los ntawm cov ntxhia pob zeb ruaj khov, ua rau nws tiv taus qhov o lossis warping uas nqus dej ua rau lwm yam khoom.
Qhov tsis muaj qhov nqus dej tseem ceeb yog ib qho ntawm cov laj thawj vim li cas granite yog cov khoom nyiam rau cov platforms precision. Hauv kev sib piv rau lwm cov ntaub ntawv uas yuav nthuav tawm lossis cog lus vim qhov hloov pauv ntawm cov av noo, granite qhov hygroscopicity tsawg ua kom ntseeg tau tias nws tseem nyob ruaj khov txawm tias nyob rau hauv ib puag ncig nrog cov qib noo noo fluctuating. Cov yam ntxwv no yog qhov tseem ceeb tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau qhov tseeb siab, qhov twg txawm tias qhov me me hloov pauv tuaj yeem ua rau muaj qhov yuam kev hauv kev ntsuas.
Txawm hais tias granite tsis nqus noo noo mus rau qhov pom tau, cov av noo heev tseem tuaj yeem cuam tshuam rau nws qhov chaw. Yog tias raug cov dej noo siab rau lub sijhawm ntev, qhov saum npoo ntawm granite tuaj yeem khaws qee qhov dej noo, tab sis qhov no feem ntau tsis txaus ua rau deformation lossis poob ntawm qhov tseeb. Qhov tseeb, thaum kho thiab kaw kom zoo, granite platforms muaj kev tiv thaiv ib puag ncig xws li ya raws, kub hloov pauv, thiab tshuaj lom neeg raug.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov, txawm li cas los xij, kev saib xyuas kom zoo yog qhov tseem ceeb kom ua kom granite platforms nyob rau hauv qhov zoo. Txawm hais tias granite qhov kev tiv thaiv tsis zoo rau kev nqus dej yog qhov zoo dua, nws tseem pom zoo kom khaws cov platform no hauv ib puag ncig uas tswj cov av noo. Nyob rau hauv cov cheeb tsam ntawm high humidity, xyuas kom meej tias lub platform yog khaws cia nyob rau hauv ib tug huab cua-tswj chav tsev nrog zoo ib yam kub thiab av noo theem yuav tiv thaiv tej yam sab nraud los ntawm influencing nws cov kev ua tau zoo.
Hauv kev xaus, granite precision platforms tsis hygroscopic nyob rau hauv ib txwm kev txiav txim siab, thiab lawv muaj peev xwm tiv taus high humidity tsis deforming ua rau lawv zoo tagnrho rau precision daim ntaub ntawv. Lawv qhov nqus dej tsawg ua kom ntseeg tau tias lawv tswj hwm lawv qhov tseeb thiab ruaj khov, txawm tias nyob hauv qhov chaw ntub dej. Txawm li cas los xij, txhawm rau ua kom muaj kev ua haujlwm ntev, nws tseem pom zoo kom khaws thiab ua haujlwm cov platforms no hauv ib puag ncig uas tswj qhov kub thiab av noo. Los ntawm kev nkag siab txog cov khoom ntawm granite thiab kev ceev faj kom tsim nyog, kev lag luam tuaj yeem ua tiav cov khoom siv lub zog thiab ruaj khov rau kev ua haujlwm siab.
