Granite, lub pob zeb tsis zoo ntawm lub ntuj tsim feem ntau ntawm quartz, feldspar, thiab mica, tau ntev tau lees paub rau nws txoj kev zoo nkauj thiab kav ntev. Txawm li cas los xij, nws qhov tseem ceeb txuas ntxiv dhau ntawm architecture thiab countertops; granite plays lub luag haujlwm tseem ceeb hauv kev ruaj ntseg ntawm cov tshuab kho qhov muag. Kev nkag siab txog kev tshawb fawb tom qab granite qhov kev ruaj ntseg tuaj yeem ua rau pom kev ntawm nws cov ntawv thov hauv qhov chaw siab xws li cov chaw soj ntsuam thiab cov chaw tsim khoom.
Ib qho ntawm cov laj thawj tseem ceeb vim li cas granite tau txais kev pom zoo hauv cov tshuab kho qhov muag yog nws qhov zoo heev rigidity. Qhov ntom ntom ntawm cov pob zeb no ua rau nws tswj hwm kev ncaj ncees raws li kev sib txawv ntawm ib puag ncig. Qhov kev nruj no txo qis kev co thiab deformation, uas yog qhov tseem ceeb hauv kev ua haujlwm kho qhov muag. Hauv qhov system kho qhov muag, txawm tias qhov kev txav me ntsis tuaj yeem ua rau tsis zoo, uas tuaj yeem cuam tshuam cov duab zoo. Granite lub peev xwm nqus thiab dissipate vibrations ua rau nws yog ib qho khoom siv zoo tshaj plaws rau mounting optical Cheebtsam xws li telescopes thiab microscopes.
Tsis tas li ntawd, granite muaj tsawg coefficient ntawm thermal expansion. Cov cuab yeej no yog qhov tseem ceeb hauv kev siv kho qhov muag, vim qhov kub thiab txias tuaj yeem ua rau cov khoom nthuav dav lossis kev cog lus, uas tuaj yeem ua rau misalignment. Granite qhov tsis tshua muaj coefficient ntawm thermal expansion kom ntseeg tau tias cov khoom siv kho qhov muag nyob ruaj khov thiab ua raws li qhov tseeb txawm tias qhov kub thiab txias. Qhov kev ruaj ntseg no tseem ceeb tshwj xeeb hauv cov tshuab kho qhov muag siab, qhov tseeb yog qhov tseem ceeb tshaj plaws.
Tsis tas li ntawd, granite lub ntuj tsis kam hnav ua rau nws ruaj khov hauv kev siv kho qhov muag. Tsis zoo li lwm cov ntaub ntawv uas degrade lub sij hawm, granite tswj nws cov khoom, kom ntseeg tau ntev, kev ua haujlwm ruaj khov. Qhov kev ua haujlwm ntev no txo qhov kev xav tau ntau zaus hloov, ua granite ib qho kev xaiv pheej yig rau lub hauv paus ntawm optical systems.
Hauv cov ntsiab lus, kev tshawb fawb tom qab granite qhov kev ruaj ntseg hauv cov tshuab kho qhov muag nyob hauv nws cov rigidity, tsis tshua muaj thermal expansion, thiab durability. Cov khoom no ua granite yog ib qho khoom siv tsis tau hauv qhov chaw kho qhov muag, kom ntseeg tau tias cov tshuab ua haujlwm tau zoo thiab txhim khu kev qha. Raws li thev naus laus zis txuas ntxiv mus, granite yuav tsis ntseeg tau txuas ntxiv mus ua lub hauv paus hauv kev txhim kho cov tshuab kho qhov muag zoo.
