Granite yog hnav-resistant, tsis yooj yim rau huab cua, thiab muaj xim ci. Cov xim tuaj yeem khaws cia rau ntau tshaj 100 xyoo. Lub rooj tsavxwm muaj cov khoom sib dhos zoo. Nyob rau hauv xyoo tas los no, nws tau dav siv nyob rau hauv high-end architectural kho kom zoo nkauj tej yaam num los ntawm cov neeg siv khoom ntawm txhua lub hnub nyoog. Txawm li cas los xij, muaj ntau ntau hom granite. Feem ntau, tib neeg tsis tsuas yog tsis tuaj yeem paub qhov txawv ntawm ntau hom granite, tab sis nws yog ib qho yooj yim rau confuse granite thiab marble.
Granite yog nplua nuj nyob rau hauv cov kev pab cuam thiab muaj ntau hom, thiab tau dav siv nyob rau hauv civil engineering txij thaum ancient sij hawm. Muaj ntau tshaj 100 ntau yam ntawm ntuj granite nyob rau hauv Suav teb, feem ntau ua nyob rau hauv Sichuan, Shandong, Guangxi, Fujian, Shanxi, Henan thiab Inner Mongolia. Muaj ntau ntau hom granite. Feem ntau, tib neeg tsis tuaj yeem paub qhov txawv ntawm ntau hom granite zoo, tab sis nws yog qhov yooj yim rau confuse granite thiab marble. Niaj hnub no, peb yuav saib cov txheej txheem kev faib tawm ntawm granite:
01. Kev faib tawm los ntawm geological pob zeb homGranite tuaj yeem muab faib ua peb hom: magmatic granite, metamorphic granite thiab sedimentary granite raws li hom pob zeb hauv geology. Hom kev faib tawm no muaj ntau dua hauv kev kawm lossis cov ntaub ntawv, thiab nws tsis tshua siv hauv lub neej txhua hnub kom paub qhov txawv
02. Muab faib raws li qhov loj ntawm cov feldspar crystals muaj Feem ntau hais lus, granite tuaj yeem muab faib ua peb hom:
nplua-grained granite, nruab nrab-grained granite thiab coarse-grained granite. Tsis muaj qhov sib txawv loj ntawm peb. Qhov nruab nrab txoj kab uas hla ntawm nplua-grained granite feldspar muaju yog 1.6mm-3.2mm, thiab qhov ntom ntom yog qhov siab. Qhov nruab nrab txoj kab uas hla ntawm nruab nrab-grained granite feldspar muaju yog 6.4 hli. Qhov nruab nrab txoj kab uas hla ntawm coarse-grained granite feldspar crystals yog hais txog 12.7mm, thiab tseem muaj cov crystals nrog cov kab uas loj dua, qee qhov txawm ncav cuag ob peb centimeters, tab sis qhov ntom ntom ntawm coarse-grained granite kuj tsawg.
03. Xaiv los ntawm xim
Hais txog xim, Suav granite muaj xim dub, dawb, liab, grey xiav, daj, ntshav, ntsuab, xim, thiab xim series, cov xim dub thiab grey granite muaj qhov zoo hauv Suav teb. Thaum peb feem ntau paub qhov txawv ntawm granite, feem ntau ntawm lawv txawv ntawm cov xim lossis cheeb tsam, yog li hom no yuav ntau dua.
