Kev siv cov khoom siv siab heev hauv cov txheej txheem tsim khoom tab tom tseem ceeb zuj zus, tshwj xeeb tshaj yog hauv kev sib dhos roj teeb tsis siv neeg. Ib qho khoom siv uas tau txais kev saib xyuas ntau yog granite, uas paub txog nws cov khoom zoo tshaj plaws uas tuaj yeem txhim kho kev ua haujlwm zoo thiab kev raug ntawm cov txheej txheem tsim khoom.
Granite, ib lub pob zeb ntuj tsim los ntawm quartz, feldspar thiab mica, paub txog nws qhov ruaj khov thiab ruaj khov. Hauv cov kab sib dhos roj teeb tsis siv neeg, granite yog lub hauv paus zoo tagnrho rau ntau yam khoom, suav nrog cov chaw ua haujlwm, cov khoom siv thiab cov cuab yeej. Nws qhov kev ruaj khov txo qis kev co, ua kom ntseeg tau tias cov txheej txheem sib dhos zoo heev tau ua tiav nrog qhov tseeb tshaj plaws. Qhov no yog qhov tseem ceeb tshwj xeeb hauv kev tsim roj teeb, qhov twg txawm tias qhov tsis sib xws me me tuaj yeem ua rau muaj teeb meem loj hauv cov khoom kawg.
Tsis tas li ntawd xwb, qhov ruaj khov ntawm cov roj teeb granite yog lwm qhov zoo tseem ceeb. Kev sib dhos roj teeb feem ntau muaj cov txheej txheem uas tsim cua sov, thiab granite lub peev xwm los tiv taus qhov kub thiab txias tsis muaj kev sib txhuam lossis kev puas tsuaj ua rau nws yog qhov kev xaiv txhim khu kev qha rau kev tswj hwm kev ncaj ncees ntawm cov khoom siv sib dhos. Qhov kev ua kom sov no pab txhawb rau ib puag ncig tsim khoom zoo dua, thaum kawg txhim kho qhov zoo ntawm cov roj teeb tsim tawm.
Ntxiv rau nws cov khoom siv kho tshuab thiab cua sov, granite yooj yim ntxuav thiab tswj, uas yog qhov tseem ceeb hauv ib puag ncig tsim khoom uas muaj kuab paug tuaj yeem ua rau muaj qhov tsis zoo. Granite qhov xwm txheej tsis muaj qhov ntxeem tau tiv thaiv kev nqus cov tshuaj lom neeg thiab lwm yam khoom, ua kom ntseeg tau tias cov kab sib dhos tseem huv thiab ua haujlwm tau zoo.
Tsis tas li ntawd xwb, qhov zoo nkauj ntawm granite tuaj yeem txhim kho qhov chaw ua haujlwm tag nrho, tsim kom muaj kev tshaj lij, ib puag ncig zoo uas txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm thiab kev tsim khoom.
Xaus lus, kev siv granite hauv cov kab sib dhos roj teeb tsis siv neeg qhia txog qhov ua tau ntau yam thiab ua tau zoo ntawm cov khoom siv no. Nws lub zog ruaj khov, kev ruaj khov thermal thiab yooj yim ntawm kev saib xyuas ua rau nws yog ib qho khoom muaj nqis hauv kev nrhiav kev tsim roj teeb zoo, uas yog txoj hauv kev rau kev nce qib hauv kev lag luam khaws cia hluav taws xob.
