Granite yog ib qho ntawm cov ntaub ntawv nrov tshaj plaws uas siv hauv kev lag luam tsim khoom rau cov khoom siv sib dhos ua kom raug. Nws qhov ruaj khov thiab kev ruaj khov ua rau nws yog cov khoom siv txhim khu kev qha rau kev tsim cov chaw ua haujlwm ntawm lub rooj rau cov khoom siv sib dhos ua kom raug. Cov rooj granite muaj peev xwm muab qhov chaw ua haujlwm tiaj tus thiab tiaj tus uas tso cai rau kev ntsuas kom raug, ua rau lawv zoo tagnrho rau kev siv qhov tseeb. Txawm li cas los xij, txhawm rau kom tswj tau qhov tseeb ntawm cov khoom siv sib dhos thiab ua tiav cov txiaj ntsig zoo, qhov chaw ua haujlwm ntawm lub rooj granite yuav tsum ua tau raws li qee qhov yuav tsum tau ua.
Qhov chaw ua haujlwm ntawm lub rooj granite yuav tsum huv, qhuav, thiab tsis muaj kev co. Kev co tuaj yeem ua rau muaj kev cuam tshuam tsis xav tau rau qhov workpiece, thiab txhua qhov kev cuam tshuam sab nraud tuaj yeem cuam tshuam qhov tseeb ntawm kev sib dhos. Yog li ntawd, qhov chaw ua haujlwm yuav tsum raug cais tawm ntawm cov chaw ua haujlwm ntawm kev co xws li cov tshuab hnyav lossis tsheb khiav. Tsis tas li ntawd, qhov kub thiab txias ntawm qhov chaw ib puag ncig yuav tsum nyob ruaj khov kom tiv thaiv kev hloov pauv ntawm cov ntaub ntawv ua haujlwm.
Yuav kom lub rooj granite ua haujlwm tau zoo, yuav tsum tau ntxuav tas li. Cov av qias neeg, cov khib nyiab, thiab cov hmoov av tuaj yeem sib sau ua ke rau ntawm lub rooj, uas yuav cuam tshuam rau qhov tseeb ntawm cov khoom siv. Cov txheej txheem ntxuav yuav tsum suav nrog kev so qhov chaw nrog daim ntaub huv, ntub dej thiab ziab nws nrog phuam tsis muaj plaub. Tsis tas li ntawd, siv lub tshuab nqus tsev kom tshem tawm cov khib nyiab ntawm qhov chaw yog qhov pom zoo. Qee zaum, yuav tsum tau siv cov tshuaj ntxuav tshwj xeeb los tshem tawm cov xim tawv ncauj.
Lwm txoj hauv kev los tswj qhov chaw ua haujlwm ntawm lub rooj granite yog siv cov ntaub thaiv uas tiv thaiv qhov chaw ntawm kev raug rau qhov chaw ib puag ncig hnyav lossis lwm yam sab nraud. Piv txwv li, cov ntaub thaiv tiv thaiv yuav siv tau los tiv thaiv lub rooj ntawm cov teebmeem phem ntawm lub teeb UV, cov tshuaj lom neeg nchuav, lossis cov tshuaj corrosive. Qhov no ua kom lub rooj granite nyob ruaj khov thiab khaws nws qhov tiaj tus.
Xaus lus, cov rooj granite zoo tagnrho rau cov khoom siv sib dhos ua ke vim lawv lub zog, kev ruaj khov, thiab qhov tseeb. Txhawm rau kom tswj tau qhov tseeb ntawm cov khoom siv thiab ua tiav cov txiaj ntsig zoo, qhov chaw ua haujlwm ntawm lub rooj granite yuav tsum ua tau raws li qee qhov kev cai xws li kev huv, kev cais tawm ntawm kev co, thiab qhov kub thiab txias zoo tshaj plaws. Kev ntxuav tas li thiab kev siv cov npog tiv thaiv tuaj yeem pab tswj tau qhov kev ncaj ncees ntawm lub rooj granite thiab khaws nws txoj haujlwm. Kev saib xyuas kom zoo ntawm lub rooj granite thiab nws qhov chaw ua haujlwm yog qhov tseem ceeb hauv kev ua tiav qhov kev ntsuas raug thiab meej uas tseem ceeb hauv kev sib dhos ua ke ntawm cov khoom siv.
