Cov txheej txheem thiab cov lus qhia ntawm granite slab.

 

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 lub slab. Qhov nruab nrab ntawm cov granite ceev yog txij li 2.63 txog 2.75 g/cm³, ua rau nws yog cov khoom siv ruaj khov uas 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:
Granite paub txog nws qhov nqus dej tsawg, feem ntau yog li ntawm 0.1% txog 0.5%. Qhov cwj pwm no ua rau nws tiv taus kev pleev xim thiab tsim nyog rau cov txee hauv chav ua noj thiab chav dej. Qhov porosity ntawm granite tuaj yeem sib txawv raws li nws cov khoom xyaw mineral, cuam tshuam rau nws qhov ruaj khov thiab kev saib xyuas.

5. Lub zog thiab kev ruaj khov:
Cov pob zeb granite muaj lub zog compressive siab, feem ntau tshaj 200 MPa, ua rau lawv haum rau kev siv hnyav. Lawv txoj kev tiv taus khawb, cua sov, thiab tshuaj lom neeg ua rau lawv siv tau ntev dua, ua rau lawv yog qhov kev xaiv zoo rau ob qho tib si hauv tsev thiab kev lag luam.

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 koj qhov project. Nrog lawv cov khoom siv ruaj khov thiab kev zoo nkauj, cov pob zeb granite tseem yog qhov kev xaiv nyiam hauv kev tsim kho thiab tsim qauv.
