Cov platforms granite precision yog siv dav hauv kev lag luam uas xav tau kev ua haujlwm siab thiab ruaj khov, xws li metrology thiab kev tsim khoom. Muab lawv lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov tseeb ntawm qhov ntev, ib lo lus nug tseem ceeb feem ntau tshwm sim: granite hygroscopic npaum li cas, thiab nws puas tuaj yeem deform hauv qhov chaw noo noo? Kev nkag siab txog cov khoom hygroscopic ntawm granite yog qhov tseem ceeb rau kev ua kom ntseeg tau tias cov platforms no tswj hwm lawv qhov ruaj khov thiab kev ua tau zoo hauv ntau yam kev ua haujlwm.
Granite, ua ib lub pob zeb ntuj, muaj ntau yam minerals, suav nrog quartz, feldspar, thiab mica. Tsis zoo li cov ntaub ntawv xws li ntoo lossis qee yam hlau, granite muaj hygroscopicity qis heev. Qhov no txhais tau tias nws tsis nqus cov dej noo ntau los ntawm ib puag ncig, txawm tias nyob rau hauv cov huab cua noo. Cov qauv molecular ntawm granite, feem ntau yog tsim los ntawm cov noob minerals ruaj khov heev, ua rau nws tiv taus qhov o lossis warping uas kev nqus dej noo ua rau hauv lwm cov ntaub ntawv.
Qhov tsis muaj kev nqus dej ntau yog ib qho ntawm cov laj thawj vim li cas granite yog cov khoom siv zoo rau cov platforms precision. Hauv kev sib piv rau lwm cov ntaub ntawv uas yuav nthuav dav lossis cog lus vim muaj kev hloov pauv ntawm cov dej noo, granite qhov hygroscopicity qis ua kom nws tseem ruaj khov txawm tias nyob rau hauv ib puag ncig nrog cov dej noo hloov pauv. Tus cwj pwm no yog qhov tseem ceeb rau cov ntawv thov uas xav tau qhov tseeb siab, qhov twg txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev hauv kev ntsuas.
Txawm hais tias granite tsis nqus cov dej noo ntau heev, qhov dej noo ntau dhau tseem tuaj yeem cuam tshuam rau nws qhov chaw. Yog tias raug rau cov dej noo ntau heev rau lub sijhawm ntev, qhov chaw ntawm granite yuav khaws qee qhov dej noo ntawm qhov chaw, tab sis qhov no feem ntau tsis txaus los ua rau deformation lossis poob qhov tseeb. Qhov tseeb, thaum kho thiab kaw kom zoo, cov platform granite tiv taus cov yam ntxwv ib puag ncig xws li dej noo, qhov kub thiab txias hloov pauv, thiab kev raug tshuaj lom neeg.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev saib xyuas kom zoo yog qhov tseem ceeb kom cov platform granite nyob rau hauv qhov zoo tshaj plaws. Txawm hais tias granite tiv taus kev nqus dej noo yog qhov zoo tshaj plaws, nws tseem raug nquahu kom khaws cov platforms no rau hauv qhov chaw uas tswj tau qhov av noo. Hauv cov cheeb tsam uas muaj av noo siab heev, kev xyuas kom meej tias lub platform tau khaws cia rau hauv chav tswj huab cua nrog qhov kub thiab txias sib xws yuav tiv thaiv cov yam sab nraud los ntawm kev cuam tshuam nws cov kev ua tau zoo.
Xaus lus, cov platform granite precision tsis yog hygroscopic hauv kev nkag siab ib txwm muaj, thiab lawv lub peev xwm los tiv taus cov av noo siab yam tsis muaj deforming ua rau lawv zoo tagnrho rau kev siv precision. Lawv qhov kev nqus dej noo qis ua kom lawv tswj tau lawv qhov tseeb thiab ruaj khov, txawm tias nyob rau hauv qhov chaw noo noo. Txawm li cas los xij, txhawm rau kom ntseeg tau tias muaj kev ua tau zoo mus sij hawm ntev, nws tseem pom zoo kom khaws cia thiab ua haujlwm cov platforms no hauv qhov chaw uas qhov kub thiab txias raug tswj. Los ntawm kev nkag siab txog cov khoom ntawm granite thiab kev ceev faj tsim nyog, kev lag luam tuaj yeem siv tag nrho cov khoom siv lub zog thiab kev ruaj khov rau cov haujlwm siab.
