Cov hauv paus tshuab granite tau nrov zuj zus hauv kev lag luam tsim khoom thiab kev siv tshuab vim lawv cov yam ntxwv tshwj xeeb, uas tuaj yeem txhim kho kev ua haujlwm ntawm lub tshuab. Kev xaiv lub hauv paus tshuab yog qhov tseem ceeb vim nws cuam tshuam ncaj qha rau qhov tseeb, kev ruaj khov thiab lub neej ua haujlwm ntawm cov khoom siv.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov cuab yeej siv tshuab granite yog lawv qhov kev ruaj khov tshwj xeeb. Granite yog cov khoom siv ntom thiab muaj zog uas txo qhov kev co thaum lub sijhawm ua haujlwm. Qhov kev ruaj khov no ua kom lub tshuab tswj tau nws qhov kev sib dhos thiab kev ua haujlwm raug, ua rau qhov zoo dua qub thiab txo qhov hnav ntawm cov cuab yeej txiav. Qhov sib piv, cov hlau ib txwm muaj peev xwm khoov lossis co thaum muaj cov khoom hnyav, uas tuaj yeem cuam tshuam rau qhov tseeb ntawm kev ua haujlwm machining.
Lwm yam tseem ceeb yog qhov ruaj khov ntawm thermal. Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov no yog qhov tseem ceeb hauv cov chaw uas muaj kev hloov pauv ntawm qhov kub thiab txias ntau zaus, vim nws pab tswj lub tshuab qhov tseeb ntawm qhov ntev. Cov tshuab uas tau teeb tsa rau ntawm cov hauv paus granite yuav tsis tshua muaj kev hloov pauv thermal, ua rau muaj kev ua haujlwm ruaj khov dhau sijhawm.
Tsis tas li ntawd xwb, cov hauv paus tshuab granite tiv taus kev xeb thiab kev hnav, yog li lawv kav ntev dua. Tsis zoo li cov hauv paus hlau uas tuaj yeem xeb lossis lwj mus raws sijhawm, granite tsis cuam tshuam los ntawm dej noo thiab tshuaj lom neeg, ua kom lub tshuab khiav tau zoo rau ntau xyoo yam tsis tas yuav saib xyuas ntau.
Tsis tas li ntawd xwb, qhov zoo nkauj ntawm granite tsis tuaj yeem tsis quav ntsej. Nws qhov chaw ci ntsa iab tsis yog tsuas yog zoo li kev tshaj lij xwb, tab sis nws kuj yooj yim los ntxuav, uas yog qhov tseem ceeb rau kev tswj hwm qhov chaw ua haujlwm huv.
Hauv kev xaus lus, cov hauv paus tshuab granite ua rau lub tshuab ua haujlwm tau zoo dua los ntawm kev muab kev ruaj khov zoo dua, kev ruaj khov thermal, kev tiv thaiv corrosion thiab kev zoo nkauj. Raws li kev lag luam txuas ntxiv nrhiav txoj hauv kev los txhim kho kev ua haujlwm zoo thiab qhov tseeb, kev siv cov hauv paus tshuab granite yuav loj hlob, ua rau nws yog qhov kev nqis peev muaj txiaj ntsig rau cov tuam txhab tsim khoom uas nrhiav kev ua tau zoo hauv lawv cov txheej txheem machining.
