Koj puas tuaj yeem paub qhov txawv ntawm granite thiab marble?

Marble thiab granite muaj ntau dua thiab nrov dua hauv tsev kho kom zoo nkauj vim lawv qhov zoo nkauj thiab kav ntev.

Ntawm no' s yuav ua li cas paub qhov txawv ntawm granite los ntawm marble.

Muaj ob lub ntsiab pob zeb: tib neeg tsim thiab ntuj.

Ntawm no peb tsuas yog ua kom paub ntuj marble thiab natural granite.

Ntuj marble yog lub qub pob zeb nyob rau hauv lub crust los ntawm kub thiab siab siab ua thiab kev tsim ntawm metamorphic pob zeb.

Pob zeb tawv nruab nrab, mas calcite, limestone, serpentine thiab dolomite muaj pes tsawg leeg.

Lub ntsiab tseem ceeb yog calcium carbonate, suav rau ntau tshaj 50%.

Lwm tus suav nrog magnesium carbonate, calcium oxide, manganese oxide thiab silicon dioxide.

Vim tias marble muaj qhov ua tsis muaj zog feem ntau, cov calcium carbonate hauv cov huab cua tau cuam tshuam los ntawm cov pa roj carbon dioxide, carbide thiab chav, kuj yooj yim rau qhov sib xyaw thiab yaj, lub nplaim sai poob luster.

Yog li ntawd, qee yam, xws li dawb marble thiab ai nej qing, yog qhov ntshiab thiab kuj ruaj khov thiab ruaj khov thiab tuaj yeem siv sab nraum zoov.

Lwm yam ntxiv tsis haum rau kev siv sab nraum zoov, feem ntau tsuas yog siv rau cov chaw kho kom zoo nkauj sab hauv.

Lub ntuj marble tuaj yeem tsim ua cov vaj huam sib luag ua kom zoo nkauj rau cov khoom ua kom zoo nkauj, siv rau sab hauv phab ntsa, ntsib cov chaw, pob zeb, pua plag tsev, windowsills, tsev tos qhua, chaw ua yeeb yaj kiab, tsev ua yeeb yaj kiab, khw khw, tsev qiv ntawv, tshav dav hlau, chaw nres tsheb hauv xov tooj cua thiab lwm cov phiaj xwm kev tsim kho pej xeem yog zoo tagnrho rau qib-qib tsim kho kom zoo nkauj sab hauv ua tiav nrog cov platform thiab of elevator qhov rooj.

Tsis tas li ntawd, nws tseem tuaj yeem siv ua murals murals, xuas tes ua, khoom siv txhua hnub, thiab lwm yam.

Ntuj granite yog cov pob zeb tsis tuaj yeem, tseem hu ua acid crystal plutonic pob zeb.

Nws yog pob zeb uas faib ntau tshaj plaws hauv cov pob zeb tsis zoo.

Nws yog lub pob zeb tawv, muaj xws li feldspar, quartz, thiab mica.

Nws cov lus muaj pes tsawg leeg yog li ntawm silica, txheeb txog li 65%.

~ 75%.

Cov pob zeb ua pob zeb tawv thiab ntom, thiab raws li lawv cov qoob loo loj, lawv tuaj yeem faib ua peb hom: pegmatite, coarse nplej thiab nplua nplej.

Qhov zoo ntawm granite yog txiav txim siab los ntawm cov ntxhia pob zeb ua ke thiab cov qauv.

Cov khoom lag luam zoo ntawm cov pob zeb granite nplua nuj yog qhov zoo thiab teeb, mica cov ntsiab lus yog me me, cov ntsiab lus quartz yog loj, tsis muaj pyrite.

Granite tsis yooj yim yuav raug weathered thiab metamorphosed, thiab nws cov tsos thiab xim tuaj yeem khaws cia rau ntau dua ib puas xyoo. Nws yog tsuas yog siv rau txheej txheem phab ntsa thiab sab nrauv phab ntsa kho kom zoo nkauj.

Granite, vim nws lub siab tawv thiab hnav tsis kam, kuj tseem feem ntau siv nyob rau hauv kev ua tiav qib siab kho kom zoo nkauj hauv tsev ua haujlwm, xws li cov rooj zaum hauv tsev.

Vim tias granite ua nyuaj dua thiab ntau dua cov kua qaub dua li marble, nws yog qhov tsim nyog rau cov chaw ua si sab nraum zoov, tshav puam, cov plag tsev ntawm cov chav ua noj, thiab lub qhov rais sills rau kev kho kom zoo nkauj hauv tsev.

Marble tuaj yeem siv rau saum txee, ua noj ua haus txee thiab cov txee rau hauv cov txee tsev noj mov.

1. Granite: Granite tsis muaj kab xim, ntau dua rau cov xim taw tes, muaj xim ntshiab.

Ua kom mos mos zoo nkauj ntxhia ntxhia dua, ntau cov qauv thiab cov qauv yog.

2. Marble SLATE: marble khoom siv ntxhia ua ke muaj pes tsawg leeg yog yooj yim txheej txheem, feem ntau ntawm kev ntxhib los mos yog exquisite, daim iav nyhuv yog qhov zoo.

Qhov tsis zoo yog tias qhov kev ntxhib los mos yog softer dua li granite thiab nws yooj yim puas thaum ntaus los ntawm cov khoom hnyav, thaum lub pob zeb lub teeb xim tau yooj yim.

Sim ua kom xaiv ib qho xim rau hauv pem teb marble. Cov khoom siv txaij ua haujlwm zoo dua thaum xaiv cov txee rau.

Lwm txoj hauv kev xaiv tuaj yeem xa mus rau txheej txheem xaiv granite.
