Lub hauv paus granite yog ib qho tseem ceeb ntawm cov khoom siv ua duab. Nws yog ib qho chaw tiaj tiaj ua los ntawm cov granite zoo uas ua haujlwm ua lub platform ruaj khov thiab ruaj khov rau cov khoom siv. Cov hauv paus granite yog nrov tshwj xeeb hauv cov ntawv thov ua duab qib kev lag luam uas qhov kev ruaj khov, qhov tseeb, thiab qhov tseeb yog qhov tseem ceeb.
Granite yog ib yam khoom zoo tshaj plaws rau kev siv hauv kev ua duab vim nws ruaj khov heev thiab tiv taus qhov kub thiab txias thiab lwm yam ib puag ncig. Lub pob zeb kuj tseem ntom heev, uas txhais tau tias nws muaj qhov coefficient qis ntawm thermal expansion (CTE). Qhov cwj pwm no ua kom lub hauv paus granite tsis nthuav dav lossis cog lus nrog kev hloov pauv ntawm qhov kub thiab txias, txo qhov kev pheej hmoo ntawm kev cuam tshuam duab.
Tsis tas li ntawd xwb, qhov chaw tiaj tiaj ntawm lub hauv paus granite tshem tawm txhua qhov kev co, ua kom ntseeg tau tias kev ua cov duab raug thiab meej. Qhov ceev ntawm granite kuj ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv suab nrov, ntxiv rau kev ua cov ntaub ntawv duab kom meej thiab meej.
Hauv kev ua cov duab, qhov tseeb ntawm cov khoom siv yog qhov tseem ceeb heev. Txhua qhov tsis sib xws lossis qhov yuam kev hauv kev ua cov txheej txheem tuaj yeem ua rau cov txiaj ntsig tsis raug thiab kev tshuaj xyuas tsis zoo. Qhov ruaj khov uas muab los ntawm lub hauv paus granite ua kom ntseeg tau tias cov khoom siv tseem nyob hauv qhov chaw yam tsis muaj kev txav mus los, ua rau cov txiaj ntsig tseeb tshaj plaws.
Nws yog ib qho tsim nyog sau tseg tias cov hauv paus granite tsis yog tsuas yog siv rau hauv cov cuab yeej ua duab qib industrial xwb, tab sis kuj tseem siv rau hauv cov khoom siv kuaj mob siab xws li microscopes, qhov twg kev ruaj khov thiab kev ua kom raug yog qhov tseem ceeb.
Hauv kev xaus lus, lub hauv paus granite ua lub hauv paus tseem ceeb rau cov cuab yeej ua duab, xa kev ruaj khov, qhov tseeb, thiab qhov tseeb rau qhov tseeb tshaj plaws thiab raug. Nws tus qauv tsim thiab kev tsim kho yog tsim los muab kev co tsawg kawg nkaus thiab nthuav dav lossis cog lus kub, tsim kom muaj kev ruaj khov thiab muaj kev nyab xeeb rau kev ua duab. Rau cov lag luam nrog cov qauv nruj ntawm kev ua tau zoo thiab qhov tseeb, nws yog ib qho khoom siv txhim khu kev qha thiab tsim nyog los lav qhov ua tiav hauv kev ua duab.
