Lub platform granite yog lub platform ua los ntawm granite. Tsim los ntawm pob zeb igneous, granite yog pob zeb tawv, crystalline. Chiv thawj muaj feldspar, quartz, thiab granite, nws yog interspersed nrog ib lossis ntau yam minerals dub, txhua yam teeb tsa ua ib qho qauv zoo sib xws.
Granite feem ntau yog ua los ntawm quartz, feldspar, thiab mica. Feldspar suav txog 40% -60%, thiab quartz rau 20% -40%. Nws cov xim nyob ntawm hom thiab qhov ntau ntawm cov khoom no. Granite yog pob zeb crystalline tag nrho. Granite zoo muaj cov noob zoo thiab sib xws, cov qauv ntom ntom, cov ntsiab lus quartz siab, thiab lub ci ntsa iab feldspar.
Granite muaj cov silica ntau, ua rau nws yog pob zeb acidic. Qee cov granites muaj cov khoom siv radioactive me ntsis, yog li cov granite no yuav tsum tsis txhob siv rau sab hauv tsev. Granite muaj cov qauv ntom ntom, cov qauv tawv, thiab tiv taus cov kua qaub, alkalis, thiab huab cua, ua rau nws tsim nyog rau kev siv sab nraum zoov ntev. Granite muaj cov yam ntxwv hauv qab no:
1. Granite muaj cov qauv ntom ntom, lub zog compressive siab, nqus dej tsawg, qhov nyuaj ntawm qhov chaw siab, kev ruaj khov tshuaj lom neeg zoo, thiab lub zog ruaj khov, tab sis tsis zoo rau hluav taws.
2. Granite muaj cov qauv granular nrog cov noob me me, nruab nrab, lossis cov noob loj, lossis cov qauv porphyritic. Nws cov noob yog sib xws thiab zoo, nrog cov qhov me me (porosity feem ntau yog 0.3% txog 0.7%), nqus dej tsawg (feem ntau 0.15% txog 0.46%), thiab zoo tiv taus te.
3. Granite yog ib yam khoom tawv, nrog rau Mohs hardness ntawm kwv yees li 6 thiab qhov ceev ntawm 2.63 g / cm³ txog 2.75. Qhov g / (cm³) ntau yam muaj lub zog compressive ntawm 100-300 MPa, nrog rau cov granite zoo-grained ncav cuag ntau dua 300 MPa. Nws lub zog flexural feem ntau yog ntawm 10 thiab 30 MPa.
Qhov thib plaub, granite muaj cov txiaj ntsig zoo, ua tau raws li ntau yam kev ua, thiab muaj cov yam ntxwv zoo heev ntawm kev sib txuas slab. Tsis tas li ntawd, granite tsis yooj yim puas, ua rau nws tsim nyog rau kev kho kom zoo nkauj sab nraum zoov.
Kev tswj lub platform marble (marble slab) yuav tsum tau txiav txim siab qhov kev kam rau siab thiab kev saib xyuas ntawm lub platform marble tam sim no, nrog rau kev txiav txim siab seb qhov chaw ua haujlwm puas muaj qhov. Yog tias lub platform marble muaj qhov me me ntawm nws qhov chaw, nws yuav tsum tau xa rov qab mus rau lub Hoobkas rau kev ua tiav. Yog tias qhov kev ua haujlwm tsuas yog hloov pauv, kev kho yuav tsum tau ua ntawm qhov chaw siv. Tom qab siv sijhawm ntev, ntau zaus, lub platform marble yuav Yog tias lub platform marble tiaj tus, qhov yuam kev precision yuav maj mam nce ntxiv, ua rau qhov kev ua haujlwm precision tsis raug. Hauv qhov no, nws yuav tsum tau kho.
Cov kauj ruam txij nkawm rau cov platforms marble:
1. Tshawb xyuas qhov tseeb ntawm lub platform marble thiab txiav txim siab nws qhov yuam kev tam sim no.
2. Siv cov khoom siv txhuam thiab cov cuab yeej sib tsoo los zom cov pob zeb marble kom tiaj tiaj.
3. Qhov thib ob semi-fine sib tsoo ntawm lub platform marble tom qab qhov sib tsoo ntxhib yog kom tshem tawm cov khawb tob thiab ua tiav qhov sib npaug xav tau.
4. Sib tsoo qhov chaw ua haujlwm ntawm lub platform marble kom ua tiav qhov kev txiav txim siab xav tau.
5. Sim qhov tseeb ntawm lub platform marble tom qab txhuam, thiab dua tom qab ib lub sijhawm.
