Granite thiab quartzite yog ob qho tib si ntuj pob zeb nquag siv hauv countertops thiab lwm yam kev siv, tab sis lawv muaj qhov sib txawv ntawm lawv cov muaj pes tsawg leeg, tsos, thiab kev ua tau zoo. Nov yog qhov sib txawv tseem ceeb ntawm granite thiab quartzite:
Kev sib xyaw:
Granite:Granite yog lub pob zeb uas tsis muaj zog uas feem ntau muaj quartz, feldspar, mica, thiab lwm yam minerals. Cov zaub mov muab granite nws qhov tshwj xeeb thiab ntau yam tsos.
Quartzite:Quartzite yog cov pob zeb metamorphic uas tsim los ntawm cov xuab zeb nyob rau hauv qhov kub thiab txias. Nws yog tsim los ntawm quartz siv lead ua nrog me me ntawm lwm yam minerals.
Hardness:
Granite:Granite paub txog nws cov durability thiab hardness. Nws yog lub pob zeb tawv thiab tawv, ua rau nws tiv taus khawb thiab hnav txhua hnub.
Quartzite:Quartzite tseem nyuaj dua li granite. Nws yog ib qho ntawm cov pob zeb nyuaj tshaj plaws, ua rau nws tiv taus khawb thiab puas.
Qhov tsos:
Granite:Granite muaj ntau yam xim thiab cov qauv vim muaj ntau yam minerals nyob rau hauv nws muaj pes tsawg leeg. Cov tsos mob tuaj yeem yog speckled, mottled, lossis veined.
Quartzite:Quartzite feem ntau muaj qhov zoo sib xws rau marble, nrog cov xim dawb lossis xim xim thiab cov leeg uas yuav hloov maj mam los yog ua siab tawv. Nws kuj tuaj yeem muaj ntau yam xim nyob ntawm cov zaub mov tam sim no.
Porosity thiab Absorption:
Granite:Granite yog ntxeem tau rau qee qhov, thiab nws qhov porosity tuaj yeem sib txawv nyob ntawm hom tshwj xeeb. Nws feem ntau yuav tsum tau muab lub sijhawm sib khi kom tsis txhob muaj xim.
Quartzite:Quartzite feem ntau tsis muaj qhov ntxeem tau ntau dua li granite, ua rau nws tiv taus ntau dua. Txawm li cas los xij, nws tseem yuav tau txais txiaj ntsig los ntawm kev sib khi, tshwj xeeb tshaj yog nyob rau hauv qhov chaw siv siab.
Thaum tshav kub kub Resistance:
Granite:Granite paub txog nws cov cua sov thiab tuaj yeem tiv taus cov lauj kaub kub thiab lauj kaub yam tsis muaj kev puas tsuaj.
Quartzite:Quartzite kuj tseem muaj cua sov, tab sis nws yog ib qho kev coj ua zoo los siv trivets lossis cov ntaub qhwv kub los tiv thaiv pob zeb thiab nws cov sealant.
Kev tu:
Ob leeg granite thiab quartzite xav tau kev tu thiab tu. Thaum granite yuav xav tau kev sib khi ua ntu zus, quartzite yuav xav tau kev sib khi tsawg dua vim nws qhov porosity qis dua.
Thaum xaiv ntawm granite thiab quartzite, xav txog tej yam xws li koj nyiam kev zoo nkauj, theem ntawm durability yuav tsum tau rau koj daim ntawv thov tshwj xeeb, thiab lub sij hawm tu koj nyiam. Nws tseem pom zoo kom sab laj nrog cov kws tshaj lij pob zeb lossis cov chaw muag khoom kom ntseeg tau tias cov khoom siv tau xaiv raws li koj cov kev xav tau tshwj xeeb.
