# Vim li cas thiaj siv Granite ua qhov ntsuas ntsuas qhov tseeb
Granite tau ntev tau lees paub tias yog cov khoom siv zoo tshaj plaws rau cov cuab yeej ntsuas qhov tseeb, thiab yog vim li cas. Nws cov khoom tshwj xeeb ua rau nws yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv hauv kev tsim, engineering, thiab kev tswj kom zoo.
Ib qho ntawm cov laj thawj tseem ceeb los siv granite ua cov cuab yeej ntsuas qhov tseeb yog nws qhov tshwj xeeb ruaj khov. Granite yog lub pob zeb uas tsis muaj zog uas ua rau muaj qhov thermal expansion tsawg, uas txhais tau hais tias nws tuav nws qhov ntev txawm tias nyob rau hauv qhov kub thiab txias. Qhov kev ruaj ntseg no yog qhov tseem ceeb rau kev ntsuas qhov tseeb, txawm tias qhov hloov pauv me me tuaj yeem ua rau muaj qhov yuam kev loj hauv kev ntsuas.
Lwm qhov zoo ntawm granite yog nws hardness. Nrog rau Mohs hardness ntsuam xyuas ntawm ib ncig ntawm 6 mus rau 7, granite yog resistant rau khawb thiab hnav, xyuas kom meej tias ntsuas qhov chaw nyob twj ywm du thiab raug raws sij hawm. Qhov kev ruaj khov no yog qhov tseem ceeb tshwj xeeb hauv ib puag ncig uas cov cuab yeej nquag siv thiab raug hnav thiab tsim kua muag.
Granite kuj muaj qhov zoo tshaj plaws flatness, uas yog ib qho tseem ceeb rau precision ntsuas cov cuab yeej xws li daim hlau nto thiab ntsuas blocks. Lub tiaj tiaj tso cai rau kev ntsuas kom raug thiab pab ua kom cov khoom sib dhos thaum lub sijhawm tsim khoom. Lub flatness ntawm granite tuaj yeem ntsuas rau qhov ua siab ntev ntawm ob peb microns, ua rau nws haum rau cov ntawv thov siab.
Tsis tas li ntawd, granite yog non-porous thiab chemically resistant, uas txhais tau hais tias nws muaj peev xwm tiv taus ntau yam khoom yam tsis muaj degrading. Cov cuab yeej no muaj txiaj ntsig tshwj xeeb hauv cov chaw lag luam uas cov cuab yeej tuaj yeem cuam tshuam nrog cov roj, cov kuab tshuaj, lossis lwm yam tshuaj.
Thaum kawg, granite qhov kev thov kom zoo nkauj tsis tuaj yeem raug saib xyuas. Nws txoj kev zoo nkauj ntuj ua rau nws yog ib qho kev xaiv nrov rau cov hom phiaj tso saib hauv chav kuaj thiab kev cob qhia, txhim kho tag nrho ib puag ncig.
Hauv kev xaus, kev siv granite ua cov cuab yeej ntsuas qhov tseeb yog tsim nyog los ntawm nws txoj kev ruaj ntseg, hardness, flatness, tshuaj tsis haum, thiab zoo nkauj zoo nkauj. Cov cwj pwm no ua rau granite yog ib qho khoom siv tseem ceeb hauv thaj tsam ntawm kev ntsuas qhov tseeb, kom ntseeg tau qhov tseeb thiab kev ntseeg siab hauv ntau yam kev siv.
