Granite yog ib yam khoom siv nrov rau kev tsim lub hauv paus ntawm cov khoom siv sib dhos ua kom raug vim nws qhov kev ruaj khov siab, kev ua haujlwm ntev, thiab kev tiv taus kev hnav thiab rhuav. Txawm hais tias granite yog ib qho kev xaiv khoom siv zoo heev rau ntau daim ntawv thov, nws tseem muaj qhov tsis zoo lossis kev txwv, tshwj xeeb tshaj yog thaum siv rau hauv cov khoom siv sib dhos ua kom raug. Cia peb tshawb nrhiav qee qhov tsis zoo ntawm cov hauv paus granite hauv cov khoom siv sib dhos ua kom raug thiab cov hau kev los txo cov teeb meem no.
Ib qho ntawm cov kev txwv tseem ceeb tshaj plaws ntawm granite ua cov khoom siv rau cov khoom siv sib dhos ua ke yog nws qhov kev nyiam ntuj tsim kom khoov lossis khoov dhau sijhawm. Txawm tias muaj kev saib xyuas thiab kev ntsuas tsis tu ncua, lub hauv paus granite thaum kawg tuaj yeem poob nws qhov chaw tiaj tiaj vim nws cov khoom sib xyaw. Qhov no tuaj yeem ua rau muaj kev sib dhos tsis sib haum, uas tuaj yeem cuam tshuam tsis zoo rau qhov tseeb thiab kev sib xws ntawm cov txheej txheem sib dhos.
Lwm qhov tsis zoo ntawm cov hauv paus granite rau cov khoom siv sib dhos precision yog lawv qhov kev cuam tshuam rau kev tawg thiab tawg. Vim yog qhov tawv thiab kev ruaj khov ntawm granite, nws tuaj yeem tawg lossis tawg thaum raug kev cuam tshuam sai lossis hnyav. Qhov no tuaj yeem tshwm sim yog tias lub cuab yeej raug poob lossis ntaus los ntawm ib yam khoom hnyav. Txhua qhov kev tawg lossis kev puas tsuaj tuaj yeem ua rau muaj qhov tsis raug hauv cov txheej txheem sib dhos, thiab kev kho lossis hloov pauv ntawm lub hauv paus granite tawg tuaj yeem siv sijhawm thiab kim.
Cov hauv paus granite kuj tseem muaj qhov txwv ntawm qhov loj thiab qhov hnyav. Vim yog qhov ntom ntawm cov khoom siv, nws tuaj yeem nyuaj rau kev tsim cov hauv paus granite loj dua yam tsis muaj teeb meem nrog qhov hnyav thiab kev yooj yim nqa. Qhov hnyav ntawm lub hauv paus yuav ua rau nws nyuaj rau txav lossis hloov chaw ntawm lub cuab yeej, thiab qhov hnyav tuaj yeem ua rau cov nqi xa khoom nce ntxiv thiab kev nyuaj siab rau kev thauj mus los.
Lwm qhov teeb meem uas yuav tshwm sim nrog cov hauv paus granite rau cov khoom siv sib dhos ua ke yog lawv qhov kev hloov pauv kub. Txawm hais tias lawv tiv taus cua sov thiab txias, cov hauv paus granite tseem tuaj yeem nthuav dav lossis cog lus thaum muaj kev hloov pauv kub. Qhov no tuaj yeem ua rau muaj teeb meem sib dhos, qhov yuam kev ntsuas, thiab lwm yam teeb meem uas tuaj yeem cuam tshuam tsis zoo rau cov txheej txheem sib dhos.
Txawm hais tias muaj cov kev txwv no los xij, tseem muaj ntau yam zoo rau kev siv cov hauv paus granite rau cov khoom siv sib dhos ua kom raug. Ib txoj hauv kev los txo qhov teeb meem no yog xyuas kom meej tias cov hauv paus granite tau npaj kom raug thiab khaws cia kom zoo. Qhov no tuaj yeem suav nrog kev ntsuas tsis tu ncua, kev sib tsoo ntawm qhov chaw, kev txhuam kom zoo, thiab kev saib xyuas rau txhua yam cim ntawm kev ntswj lossis tawg. Kev ntxuav thiab tua kab mob ntawm qhov chaw tsis tu ncua kuj tseem tuaj yeem pab tswj kom muaj chaw ua haujlwm huv thiab huv si, txo cov kev pheej hmoo ntawm kev ua qias tuaj.
Hauv kev xaus lus, cov hauv paus granite muaj ntau yam zoo uas ua rau lawv yog qhov kev xaiv zoo heev rau cov khoom siv sib dhos ua kom raug. Txawm li cas los xij, lawv tsis yog tsis muaj lawv qhov tsis zoo, xws li kev nkhaus, tawg, qhov hnyav txwv, thiab qhov kub thiab txias. Los ntawm kev paub txog cov teeb meem no thiab ua cov kauj ruam los txo lawv, cov chaw tsim khoom tuaj yeem txuas ntxiv tau txais txiaj ntsig los ntawm ntau yam zoo tshwj xeeb ntawm cov hauv paus granite. Nrog kev saib xyuas zoo thiab kev saib xyuas kom meej, cov hauv paus granite tuaj yeem txuas ntxiv muab lub hauv paus txhim khu kev qha rau cov khoom siv sib dhos ua kom raug rau ntau xyoo tom ntej.
