Cov kabmob cua yog ib feem tseem ceeb ntawm ntau yam lag luam uas xav tau qhov chaw meej thiab kev daws teeb meem tswj kev txav mus los. Ib qho ntawm cov ntaub ntawv tseem ceeb siv hauv kev tsim cov kabmob cua yog granite. Granite yog pob zeb ntuj uas tsim nyog rau cov kabmob cua vim nws cov yam ntxwv tshwj xeeb. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qee qhov laj thawj vim li cas granite yog qhov kev xaiv zoo dua li hlau rau cov kabmob cua granite.
Ua ntej tshaj plaws, granite yog ib yam khoom siv uas tawv thiab ruaj khov heev. Nws muaj lub zog compressive siab, thiab tuaj yeem tiv taus qhov hnyav thiab siab ntau yam tsis muaj kev hloov pauv lossis tawg. Qhov no ua rau nws yog ib yam khoom zoo tagnrho rau cov kabmob cua, uas xav tau lub substrate ruaj khov thiab tawv kom txhawb nqa lub nra uas raug tsiv mus. Piv rau cov hlau xws li hlau lossis txhuas, granite muaj kev ruaj khov zoo dua thiab muaj peev xwm tiv thaiv kev co.
Qhov thib ob, granite tiv taus kev hnav thiab tsim kua muag heev. Nws tsis raug cuam tshuam los ntawm feem ntau cov tshuaj lom neeg lossis cov tshuaj corrosive, ua rau nws yog qhov kev xaiv zoo rau kev siv hauv qhov chaw nyuaj. Qhov sib txawv, cov hlau tuaj yeem corrode lossis degraded dhau sijhawm, uas tuaj yeem ua rau txo qhov tseeb thiab tsis ruaj khov hauv huab cua bearing.
Lwm qhov zoo ntawm kev siv granite rau cov kabmob cua yog nws lub peev xwm ntuj tsim los tso cua sov. Granite muaj cov thermal conductivity siab, uas txhais tau tias nws tuaj yeem hloov cua sov tawm ntawm qhov chaw ntawm cov kabmob. Qhov no tseem ceeb vim tias cov kabmob cua tsim cua sov thaum lub sijhawm ua haujlwm, thiab yog tias tsis tso cua sov kom raug, cua sov tuaj yeem ua rau thermal nthuav dav thiab txo qhov tseeb.
Granite kuj yog ib yam khoom uas tsis yog hlau nplaum, uas yog ib qho tseem ceeb rau qee yam kev siv xws li kev tsim khoom siv hluav taws xob lossis kev thaij duab magnetic resonance imaging (MRI). Cov hlau tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv rhiab heev los ntawm kev tsim cov teb magnetic, thaum granite tsis muaj qhov teeb meem no.
Thaum kawg, granite yog ib yam khoom zoo nkauj uas tuaj yeem ua rau cov khoom siv ua haujlwm siab dua zoo nkauj dua. Nws muaj qhov tsos tshwj xeeb uas feem ntau siv rau hauv kev tsim vaj tsev, thiab tuaj yeem ntxiv kev pom rau lwm yam khoom siv.
Xaus lus, granite yog cov khoom siv zoo tshaj plaws rau cov kabmob cua rau cov khoom siv teeb tsa vim nws cov yam ntxwv zoo ntawm kev tawv, kev ruaj khov, kev tiv taus kev hnav thiab rhuav, kev tso cua sov zoo heev, cov khoom tsis muaj hlau nplaum, thiab kev zoo nkauj. Txawm hais tias hlau yuav muaj qee qhov zoo, granite muaj kev sib xyaw ua ke zoo ntawm kev ua haujlwm thiab kev zoo nkauj uas ua rau nws yog cov khoom siv xaiv rau ntau daim ntawv thov.
