Qhov txawv ntawm qhov zoo tshaj plaws Marble thiab Granite txiav hniav?

Ob leeg granite thiab marble yog cov pob zeb nrov thiab tau siv dav hauv kev tsim kho. Qhov sib txawv ntawm granite thiab marble tseem tuaj yeem sib cais zoo, xws li cov qauv. Kev ntxhib los mos ntawm granite yog mottled, thiab kev ntxhib los mos ntawm marble tshwm. Muaj yeeb yuj qauv kev ntxhib los mos, tshwj xeeb tshaj yog zoo nkauj.

Nyob rau hauv cov nqe lus ntawm pob zeb hardness, marble yog ib tug mos pob zeb, thiab granite yog ib tug nruab nrab-nyuaj pob zeb. Hais txog hardness, granite yog me ntsis zoo dua. Nyob rau hauv cov nqe lus ntawm pob zeb hom, marble yog metamorphic pob zeb, thaum granite yog igneous pob zeb. Tsis tas li ntawd, marble muaj ntau yam xim. Ntau haiv neeg thiab muaj yeeb yuj, thaum granite feem ntau yog grey lossis dawb.

Marble yog cov pob zeb metamorphic lossis cov pob zeb carbonate. Nws yog cov txheej txheem zoo, thiab ruaj khov, tuaj yeem polished, muaj ntau yam xim, muaj xim zoo nkauj, thiab muaj hluav taws xob tsawg.

Vim tias nws tsis tiv taus huab cua thiab tsis tshua siv sab nraum zoov, marble feem ntau yog siv rau kev kho kom zoo nkauj sab hauv. Vim tias marble zoo dua, nws cov qauv yog nplua nuj, thiab nws cov xim yog mos. Tom qab tso, nws yuav tshwm sim ntau txheej, nplua nuj, thiab nplua nuj. Cov kev xav tau ntawm kev xaiv marble pom hniav yog ntau dua li cov granite pom hniav. Qhov tshwm sim ntawm chipping thiab ntog ces kaum tsis tuaj yeem tshwm sim.

Granite muaj siab hardness thiab yooj yim los tswj. Tab sis nws ua rau tib neeg lub siab txias. Nws feem ntau yog siv rau hauv av thiab phab ntsa nyob rau sab nraum zoov lossis pej xeem. Yog li ntawd, cov neeg siv khoom feem ntau muaj tsawg dua qhov kev txiav txim siab ntawm cov hniav granite dua li cov hniav marble.

Ntxiv rau qhov sib txawv saum toj no, marble txiav hniav thiab granite txiav hniav muaj qhov sib txawv hauv qab no:

Cov qauv ntu ntawm ob yog sib txawv:granite hniav xav tau ntau dua sharpness.

Cov xim ntawm cov seem yog txawv:cov seem marble feem ntau yog yellowish nyob rau hauv cov xim thiab belongs rau qib nruj, thaum lub granite seem feem ntau yog silver-grey thiab belongs rau qib hlau.

Cov grooves yog txawv:cov grooves ntawm ob qhov sib txawv, feem ntau ntawm cov marble yog U zawj los yog ib tug ntses nuv zawj, thaum lub granite pom hniav yog ib qho tseem ceeb zawj.

Scale thiab thickness ntawm ntu:Marble muaj qis hardness, yog li cov ntu marble kuj yog thinner

Tus nqi sib txawv thiab sab nraud:Marble yog me ntsis kim dua granite.

Seem kev ntxhib los mos:Qhov kev ntxhib los mos ntawm granite feem ntau yog mottled, thaum lub marble seem yog nplua nuj xim, zoo nyob rau hauv kev ntxhib los mos, thiab muaj yeeb yuj.

Welds:Cov welds ntawm ob lub substrates thiab ntu kuj txawv.
