Granite yog ib qho kev xaiv nrov rau cov khoom siv ua wafer vim nws lub zog ruaj khov, kev ruaj khov, thiab kev tiv taus xeb. Txawm hais tias hlau zoo li yog lwm txoj hauv kev xaiv tau, muaj ntau yam laj thawj vim li cas granite thiaj yog qhov kev xaiv zoo dua.
Ua ntej, granite yog ib qho nyuaj heev thiab muaj kev tiv thaiv siab rau kev hnav thiab rhuav. Qhov no txhais tau tias cov khoom siv ua wafer ua los ntawm granite tuaj yeem tiv taus kev siv tas li thiab tswj lawv cov qauv kom ruaj khov dhau sijhawm. Qhov sib txawv, cov khoom siv hlau feem ntau khoov thiab warping, uas tuaj yeem ua rau cov khoom siv tsis ua haujlwm lossis lub neej luv dua.
Qhov thib ob, granite yog ib yam khoom ruaj khov heev. Nws tsis nthuav dav lossis cog lus thaum muaj kev hloov pauv kub, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv uas raug cua sov lossis txias heev. Qhov kev ruaj khov no ua kom ntseeg tau tias qhov tseeb ntawm cov khoom siv tsis raug cuam tshuam los ntawm kev hloov pauv kub, uas yog qhov tseem ceeb tshwj xeeb hauv cov ntawv thov ua wafer rhiab heev.
Qhov thib peb, granite tiv taus xeb heev. Qhov no yog ib qho tseem ceeb hauv cov khoom siv ua wafer, vim tias cov kua ua haujlwm siv tuaj yeem ua rau xeb heev. Cov khoom siv hlau tsis yooj yim rau xeb thiab xeb, uas tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm thiab lub neej ntawm cov khoom siv.
Tsis tas li ntawd xwb, granite yog ib qho khoom rwb thaiv tsev zoo heev. Nws tsis coj hluav taws xob, uas txhais tau tias cov khoom siv hluav taws xob rhiab heev hauv cov khoom siv ua wafer raug tiv thaiv los ntawm kev cuam tshuam hluav taws xob.
Thaum kawg, granite yog ib qho kev xaiv zoo rau ib puag ncig rau cov khoom siv ua wafer. Nws yog ib yam khoom siv uas tshwm sim los ntawm ntuj uas tsis muaj tshuaj lom thiab tsis tso tawm cov tshuaj lom neeg thaum lub sijhawm nws lub neej. Qhov no ua rau nws yog ib qho kev xaiv ruaj khov rau cov tuam txhab uas cog lus tias yuav txo lawv cov kev cuam tshuam rau ib puag ncig.
Xaus lus, thaum hlau zoo li yog qhov kev xaiv ua tau rau cov khoom siv ua wafer, granite yog qhov kev xaiv zoo dua vim nws qhov ruaj khov, ruaj khov, tiv taus corrosion, cov khoom rwb thaiv tsev zoo heev, thiab kev ruaj khov. Kev xaiv granite rau cov khoom no ua kom ntseeg tau tias cov tuam txhab tuaj yeem ua cov wafers tau zoo thiab raug nrog kev saib xyuas tsawg kawg nkaus thiab muaj kev cuam tshuam tsis zoo rau ib puag ncig.
