Cov txheej txheem thiab cov lus qhia ntawm granite slabs.

 

Cov pob zeb granite yog ib qho kev xaiv nrov hauv kev tsim kho thiab kev tsim kho sab hauv vim lawv lub zog ruaj khov, kev zoo nkauj, thiab kev hloov pauv tau yooj yim. Kev nkag siab txog cov txheej txheem thiab cov lus qhia ntawm cov pob zeb granite yog qhov tseem ceeb rau cov kws kes duab vajtse, cov neeg ua vaj tse, thiab cov tswv tsev kom txiav txim siab tau zoo.

1. Kev Sib Xyaws thiab Qauv:
Granite yog pob zeb igneous uas feem ntau muaj quartz, feldspar, thiab mica. Cov khoom sib xyaw ua ke ntawm cov minerals cuam tshuam rau cov xim, cov qauv, thiab qhov tsos ntawm cov slab. Qhov nruab nrab ntawm cov granite slabs yog txij li 2.63 txog 2.75 g/cm³, ua rau lawv ruaj khov thiab haum rau ntau yam kev siv.

2. Tuab thiab Loj:
Feem ntau cov pob zeb granite muaj qhov tuab li ntawm 2 cm (3/4 nti) thiab 3 cm (1 1/4 nti). Qhov loj me ntawm cov pob zeb no txawv, tab sis qhov loj me uas feem ntau muaj xws li 120 x 240 cm (4 x 8 feet) thiab 150 x 300 cm (5 x 10 feet). Kuj muaj qhov loj me uas koj xav tau, ua rau koj tsim tau yooj yim.

3. Qhov Chaw Tiav:
Qhov tiav ntawm cov pob zeb granite tuaj yeem cuam tshuam rau lawv qhov tsos thiab kev ua haujlwm. Cov tiav tiav feem ntau suav nrog polished, honed, flamed, thiab brushed. Cov tiav tiav polished muab qhov zoo li glossy, thaum honed muab qhov chaw matte. Cov tiav flamed yog qhov zoo tagnrho rau kev siv sab nraum zoov vim lawv cov khoom tiv taus kev nplua.

4. Kev Nqus Dej thiab Qhov Porosity:
Feem ntau cov pob zeb granite muaj cov dej nqus tsawg, feem ntau yog li ntawm 0.1% txog 0.5%. Cov yam ntxwv no ua rau lawv tiv taus cov xim thiab tsim nyog rau cov txee hauv chav ua noj thiab chav dej. Qhov porosity ntawm granite tuaj yeem sib txawv, cuam tshuam rau nws cov kev xav tau txij nkawm.

5. Lub zog thiab kev ruaj khov:
Granite paub txog nws lub zog tshwj xeeb, nrog rau lub zog compressive txij li 100 txog 300 MPa. Qhov kev ruaj khov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov chaw muaj neeg coob thiab cov ntawv thov sab nraum zoov, ua kom muaj lub neej ntev thiab tiv taus kev hnav.

Xaus lus, kev nkag siab txog cov txheej txheem thiab cov lus qhia ntawm cov pob zeb granite yog qhov tseem ceeb rau kev xaiv cov khoom siv zoo rau txhua qhov project. Nrog lawv cov yam ntxwv tshwj xeeb, cov pob zeb granite tseem yog qhov kev xaiv nyiam hauv ob qho chaw nyob thiab chaw ua lag luam.
