Granite yog ib qho kev xaiv nrov rau cov txaj tshuab thaum nws los txog rau cov khoom siv ua wafer. Qhov no yog vim muaj ntau yam zoo uas granite muaj dua li hlau. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov laj thawj vim li cas ib tug neeg yuav tsum xaiv granite es tsis txhob siv hlau rau cov txaj tshuab granite.
1. Kev Ruaj Ntseg thiab Kev Rigidity
Granite paub txog nws qhov ruaj khov thiab rigidity. Nws yog ib qho qauv crystalline homogeneous uas tsis warp lossis twist nyob rau hauv ntau yam kub. Qhov no txhais tau tias nws ruaj khov dua li hlau, uas tuaj yeem nthuav dav, cog lus, thiab txawm tias distort nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov ruaj khov thiab rigidity ntawm granite ua rau nws yog ib qho khoom zoo tagnrho rau cov txaj tshuab uas xav tau qhov chaw tseeb thiab kev ntsuas raug.
2. Kev co damping
Granite muaj cov yam ntxwv zoo heev uas tiv thaiv kev co. Nws tuaj yeem nqus tau kev poob siab thiab kev co zoo dua li cov hlau. Hauv cov khoom siv ua wafer, qhov twg qhov tseeb yog qhov tseem ceeb tshaj plaws, kev co tuaj yeem ua rau muaj qhov yuam kev thiab kev ntsuas tsis raug. Yog li ntawd, kev siv cov txaj tshuab granite tuaj yeem txo qhov kev co thiab xyuas kom meej tias kev ntsuas yog qhov tseeb thiab sib xws.
3. Kev Ruaj Ntseg Thermal
Granite muaj cov coefficient qis ntawm thermal expansion, uas txhais tau tias nws nthuav dav thiab cog lus me ntsis thaum raug rau qhov kub hloov pauv. Qhov kev ruaj khov thermal no tseem ceeb hauv cov khoom siv ua wafer, qhov twg cov tshuab yuav tsum ua haujlwm ntawm qhov kub siab. Nws tseem ceeb heev hauv kev ua haujlwm precision qhov twg qhov kub hloov pauv tuaj yeem ua rau muaj kev cuam tshuam hauv cov hlau, ua rau muaj qhov tsis raug hauv kev ntsuas.
4. Kev ruaj khov thiab kev hnav tsis kam
Granite paub txog nws qhov ruaj khov thiab tiv taus kev hnav thiab rhuav. Nws yog ib yam khoom tawv thiab ntom uas tuaj yeem tiv taus cov xwm txheej hnyav yam tsis muaj kev puas tsuaj. Piv rau, hlau tuaj yeem khawb, lwj, lossis txawm tias xeb, ua rau xav tau kev kho lossis hloov pauv. Qhov ruaj khov thiab tiv taus kev hnav ntawm granite ua rau nws yog cov khoom siv pheej yig rau cov txaj tshuab hauv lub sijhawm ntev.
5. Yooj yim ntxuav
Granite yooj yim ntxuav thiab tswj. Tsis zoo li hlau, nws tsis xeb lossis lwj, thiab nws tiv taus cov tshuaj lom neeg thiab cov xim av. Hauv cov khoom siv ua wafer, qhov twg kev huv si yog qhov tseem ceeb, kev siv cov txaj tshuab granite txo qhov xav tau kev ntxuav thiab kev saib xyuas ntau zaus.
Xaus lus, qhov zoo ntawm granite dua li hlau ua rau nws yog cov khoom siv zoo tshaj plaws rau cov txaj tshuab hauv cov khoom siv ua wafer. Nws qhov ruaj khov, kev co damping, thermal stability, durability, hnav tsis kam, thiab yooj yim ntxuav ua rau nws yog qhov kev xaiv pheej yig rau cov txaj tshuab hauv lub sijhawm ntev. Yog li, kev xaiv granite dua li hlau rau cov txaj tshuab granite yog ib kauj ruam zoo rau kev txhim kho qhov zoo thiab kev ua haujlwm ntawm cov khoom siv ua wafer.
