Hom thiab qhov zoo ntawm cov khoom siv granite siv los ua lub hauv paus rau lub tshuab ntsuas kev sib koom tes (CMM) yog qhov tseem ceeb rau nws txoj kev ruaj ntseg mus sij hawm ntev thiab qhov tseeb.Granite yog cov khoom siv nrov xaiv vim nws cov khoom zoo heev xws li kev ruaj ntseg siab, tsis tshua muaj thermal expansion, thiab tsis kam hnav thiab corrosion.Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov sib txawv ntawm cov ntaub ntawv granite tuaj yeem cuam tshuam qhov kev ruaj ntseg thiab qhov tseeb ntawm CMM.
Ua ntej, nws yog ib qho tseem ceeb kom nkag siab tias tsis yog txhua yam khoom siv granite yog tib yam.Granite tuaj yeem sib txawv ntawm nws lub cev thiab tshuaj lom neeg nyob ntawm qhov chaw txua txiag zeb nws yog los ntawm, qib, thiab cov txheej txheem tsim khoom.Qhov zoo ntawm cov khoom siv granite siv yuav txiav txim siab qhov ruaj khov thiab qhov tseeb ntawm CMM, uas yog qhov tseem ceeb rau kev ua kom zoo thiab kev tsim khoom.
Ib qho tseem ceeb uas yuav tau xav txog yog qib ntawm cov ntsiab lus quartz hauv granite.Quartz yog cov ntxhia uas yog lub luag haujlwm rau hardness thiab durability ntawm granite.High-quality granite yuav tsum muaj tsawg kawg yog 20% quartz cov ntsiab lus los xyuas kom meej tias cov khoom yog ruaj khov thiab tuaj yeem tiv taus qhov hnyav thiab kev co ntawm CMM.Quartz kuj muab qhov ruaj khov, uas yog qhov tsim nyog rau kev ntsuas qhov tseeb.
Lwm qhov yuav tsum tau xav txog yog qhov porosity ntawm cov khoom siv granite.Porous granite tuaj yeem nqus dej noo thiab tshuaj lom neeg, uas tuaj yeem ua rau corrosion thiab deformation ntawm lub hauv paus.Zoo granite yuav tsum muaj tsawg porosity, ua rau nws zoo impermeable rau dej thiab tshuaj.Qhov no txhim kho qhov ruaj khov thiab raug ntawm CMM lub sijhawm.
Kev ua tiav ntawm lub hauv paus granite tseem yog qhov tseem ceeb.Lub hauv paus CMM yuav tsum muaj qhov zoo-grained nto tiav los muab kev ruaj ntseg zoo thiab raug ntawm lub tshuab.Nrog rau qhov ua tiav tsis zoo, lub hauv paus tuaj yeem muaj qhov pits, khawb, thiab lwm yam tsis xws luag uas tuaj yeem cuam tshuam qhov ruaj khov ntawm CMM.
Hauv kev xaus, qhov zoo ntawm cov khoom siv granite siv hauv CMM ua lub luag haujlwm tseem ceeb hauv nws txoj kev ruaj ntseg mus sij hawm ntev thiab qhov tseeb.High-quality granite nrog cov ntsiab lus quartz haum, tsis tshua muaj porosity, thiab nplua-grained nto tiav yuav muab qhov zoo tshaj plaws ruaj khov thiab raug rau kev ntsuas kev siv.Xaiv tus neeg muag khoom muaj npe nrov uas siv cov granite zoo los tsim lawv cov tshuab ntsuas yuav ua kom lub neej ntev ntawm CMM thiab ntsuas qhov ntsuas zoo ib yam.
