Teeb meem dab tsi yuav tshwm sim hauv kev siv cov granite thiab yuav ua li cas tiv thaiv lawv?

Taw qhia:

Cov khoom siv granite tau siv dav hauv kev tsim cov cuab yeej ntsuas thiab ntsuas khoom vim lawv cov khoom ruaj khov ruaj khov, muaj lub siab tawv, thiab qis coefficient ntawm thermal expansion. Txawm li cas los xij, nyob rau hauv kev siv cov khoom lag luam granite, qee cov teeb meem yuav tshwm sim, uas tuaj yeem cuam tshuam kev ua tau zoo ntawm cov khoom siv. Kab lus no yuav tham txog cov teeb meem no thiab cov hau kev los tiv thaiv lawv.

Teeb meem:

1. Staining:

Sij hawm dhau mus, cov khoom lag luam granite tuaj yeem tsim cov stains vim raug rau ntau yam tshuaj lom lossis cov tshuaj yeeb dej thaum lub sijhawm tsim khoom lag luam lossis siv. Stains tej zaum yuav cuam tshuam cov khoom siv ntawm cov khoom siv thiab tseem tuaj yeem hloov cov khoom saum npoo av ntawm granite, yog li cuam tshuam lawv cov kev ua tau zoo.

2. Kev tawg:

Granite tuaj yeem tawg nyob hauv qee qhov xwm txheej, xws li raug rau cov kev cuam tshuam ntau lossis kev cuam tshuam sai. Cov kab nrib pleb tuaj yeem ua rau cov qauv ntawm cov khoom siv thiab kev txiav txim siab nws raug.

3. Deformation:

Granite seem yog tsis yeem, tab sis lawv tseem tuaj yeem ua kom zoo yog tias lawv raug lub zog loj lossis thauj khoom ntau. Deformation tuaj yeem cuam tshuam qhov tseeb ntawm cov cuab yeej thiab tuaj yeem ua rau lwm cov khoom sib txawv.

Kev Tiv Thaiv:

1. Kev tu thiab txij nkawm:

Txhawm rau tiv thaiv staining, granite seem yuav tsum tau muab ntxuav kom tsis tu ncua nrog cov tshuaj ntxuav tsis sib xws. Zam txhob siv cov kua qaub lossis cov tshuaj alkaline txij li cov no tuaj yeem ua rau txhaws. Yog tias stains yog tam sim no, txawm yog ib qho poultice lossis daim ntawv thov ntawm hydrogen peroxide tuaj yeem siv rau kev tshem tawm.

2. Tsim nyog tuav thiab cia:

Granite qhov chaw yuav tsum daws nrog kev saib xyuas thiab khaws cia rau hauv ib puag ncig qhuav thiab huv. Zam txhob ua rau lawv los ncaj qha tshav ntuj lossis huab cua sov, uas tuaj yeem ua rau tawg. Cov khoom lag luam granite yuav tsum muaj kev tiv thaiv thaum thauj kom tsis txhob muaj kev cuam tshuam.

3. Cov qauv hloov kho:

Cov kev hloov kho tsim tau tuaj yeem siv los tiv thaiv kev deformation thiab kev tawg. Los ntawm kev ntxiv cov qauv kev txhawb nqa lossis kho cov qauv tsim ntawm cov khoom siv, lub thauj khoom tuaj yeem faib cov yaum sij, yog li tsis txhob muaj kev ntxhov siab ntau rau qee thaj chaw tshwj xeeb. Finite elate tsom xam (fea) kuj tseem siv tau los txheeb xyuas cov peev xwm ntawm cov chaw ntawm kev ntxhov siab.

Xaus:

Granite feem yog qhov tseem ceeb rau cov kev ntsuas siab ntsuas cov twj thiab cov khoom siv. Txawm li cas los xij, lawv yuav tsum tau siv thiab tswj kom zoo kom zam cov teeb meem. Los ntawm kev kho cov txheej txheem kho vaj tse, tuav, thiab kev sib koom ua raws, lub neej ntawm cov khoom siv tuaj yeem ntev. Cov kev tsim qauv kuj tseem tuaj yeem tsim kom muaj feem rau kev xav tau tshwj xeeb, yog li ntseeg tau tias cov cuab yeej ua rau kev ua tau zoo tshaj plaws. Nws yog qhov tseem ceeb rau kev ceev faj kev ceev faj kom tiv thaiv txhua qhov teeb meem, yog tso cai rau cov khoom siv ua haujlwm kom zoo, thiab nyeg tsim khoom ntxiv.
