Granite yog pob zeb uas tsis muaj zog (igneous pob zeb) tsim los ntawm magma. Ib feem ntawm cov av hauv av magma ntws tawm ntawm qhov chaw thaum nws nce mus rau qhov tsis muaj zog ntawm lub ntiaj teb crust. Tseem muaj ib feem ntawm magma uas yog tus tub nkeeg. Qhov kub siab melts cov pob zeb nyob ib puag ncig thiab tsis xav mus deb, yog li nws condenses nyob rau hauv cov pob zeb formations. Granite yog tsim los ntawm condensation ntawm no magma uas invaded tob underground. Vim tias muaj kev kub siab hauv cov pob zeb hauv av, qhov kev ntxhib los mos yog ib qho nyuaj thiab tsis yooj yim rau corrode.
Tus nqi ntawm granite ntsiab nyob rau hauv kho kom zoo nkauj sab hauv yog feem ntau xav nyob rau hauv ob lub ntsiab lus:
Ib qho yog cov khoom siv ua haujlwm. Ntuj granite muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, yog li nws yog qhov tsim nyog rau countertops, parapet phab ntsa, ntaiv, thiab tes tuav.
Qhov thib ob yog qhov zoo nkauj ntawm nws tus kheej cov khoom, tshwj xeeb tshaj yog tag nrho saum npoo ntawm granite thiab cov qauv zoo sib xws. Raws li cov qauv tsim, nws muaj irreplaceable zoo nkauj. Nyob rau hauv xyoo tas los no, ntau lub npe nrov sab hauv tsim tau siv granite ntsiab.
Ntawm qhov tod tes, granite cov ntsiab lus kuj tau sib xws nrog ntau qhov nrov concave-convex nto tsim, uas tuaj yeem ua tiav cov phab ntsa zoo nkauj heev.
Granite, lub ntsiab tseem ceeb ntawm lub teb chaws crust, yog ib tug igneous pob zeb tsim los ntawm condensation ntawm magma nyob rau hauv lub nto thiab belongs rau cov pob zeb sib sib zog nqus intrusive. Nws tsuas yog muaj nyob rau hauv daim ntawv ntawm cov zaub mov xws li quartz los yog feldspar. Lub etymology ntawm granite yog Latin granum, lub ntsiab lus nplej los yog nplej.
Vim tias granite yog pob zeb plutonic, feem ntau nws tuaj yeem tsim cov pob zeb zoo nkauj uas tuaj yeem ua qhov txawv ntawm qhov muag liab qab, yog li lub npe. Granite tsis yooj yim rau huab cua, muaj xim zoo nkauj, thiab nws cov tsos thiab xim tuaj yeem khaws cia rau ntau tshaj li ib puas xyoo. Vim nws lub siab tawv thiab hnav tsis kam, nws tsis yog tsuas yog siv rau qib siab architectural kho kom zoo nkauj tej yaam num thiab hauv pem teb, tab sis kuj yog thawj xaiv rau sab nraum zoov carvings.
Granite yog dav faib thoob plaws ntiaj teb, xws li hauv Asia, Europe, Africa, thiab America. Nyob rau hauv txawv teb chaws, nws yog dav faib nyob rau hauv lub tebchaws United States, South Africa, Finland, Canada, Brazil, Is Nrias teb, Sweden, thiab lwm qhov chaw. Hauv Suav teb, cov pob zeb zoo li no feem ntau faib rau hauv Inner Mongolia, Fujian, Shanxi, Sichuan, Shandong, Hubei, thiab Xinjiang. Vim nws qhov kev faib tawm dav thiab ntau hom, pob zeb no tsim nyog ua vaj ntxwv ntawm tsev neeg pob zeb.
Raws li cov khoom siv pob zeb ntuj, granite muaj ntau yam kev siv.
1. Rau architectural kho kom zoo nkauj. Granite feem ntau siv rau hauv kev kho kom zoo nkauj architectural. Piv txwv li, lub rooj vag ntawm villas, pob zeb ntawm txoj kev, thiab lwm yam yog tag nrho ua nrog cov pob zeb zoo li no ua cov khoom siv yooj yim.
2. Khoom siv tes ua carving. Tau kawg, zoo li cov jade dawb hauv marble, cov xim, kev ntxhib los mos, thiab luster zoo dua, thiab nws tuaj yeem siv rau carving lossis ua qee yam khoom siv tes ua, thiab tus nqi tsis pheej yig.
3. Cov khoom siv txhua hnub. Piv txwv li, cov ntxhuav marble thiab cov rooj zaum hauv pob zeb hauv tib neeg lub neej txhua hnub kuj yog ua los ntawm cov pob zeb no. Hauv luv luv, granite muaj ntau yam kev siv, tsuas yog koj tsis tuaj yeem xav txog nws, thiab koj siv tsis tau yam tsis muaj lawv.
