Granite, ua ib yam khoom siv dav dav hauv kev tsim kho, kho kom zoo nkauj, cov cuab yeej siv precision thiab lwm yam teb, nws qhov ceev yog qhov qhia tseem ceeb rau kev ntsuas qhov zoo thiab kev ua tau zoo. Thaum xaiv cov ntaub ntawv granite, nws yog ib qho tseem ceeb kom nkag siab txog cov yam tseem ceeb uas cuam tshuam rau lawv qhov ceev. Cov hauv qab no yuav piav qhia ntxiv rau koj.
I. Cov Khoom Siv Hauv Cov Pob Zeb
Granite feem ntau yog ua los ntawm cov zaub mov xws li quartz, feldspar thiab mica. Cov qauv siv lead ua, cov ntsiab lus thiab hom ntawm cov zaub mov no muaj feem cuam tshuam loj rau qhov ceev. Cov qauv siv lead ua ntawm quartz thiab feldspar yog qhov sib zog me me, thiab lawv cov qhov ceev yog qhov siab. Thaum cov ntsiab lus ntawm ob hom zaub mov no hauv granite siab, qhov ceev tag nrho kuj yuav nce ntxiv raws li. Piv txwv li, qee hom granite nplua nuj hauv quartz thiab feldspar feem ntau muaj qhov ceev siab. Ntawm qhov tsis sib xws, cov qauv siv lead ua ntawm mica yog qhov xoob me ntsis. Yog tias cov ntsiab lus mica hauv granite siab me ntsis, nws yuav ua rau nws qhov ceev txo qis. Tsis tas li ntawd, granite uas muaj ntau cov zaub mov nrog cov qhov hnyav molecular siab xws li hlau thiab magnesium feem ntau muaj qhov ceev siab dua. Granite, uas nplua nuj hauv cov zaub mov silicate, muaj qhov ceev qis dua.
II. Qhov Loj thiab Cov Qauv ntawm Cov Khoom Me Me
Qhov loj ntawm cov khoom me me
Cov pob zeb granite me me npaum li cas, lawv yuav sib sau ua ke ntau npaum li ntawd, thiab cov qhov me me sab hauv yuav tsawg dua, uas ua rau muaj qhov hnyav ntxiv rau ib chav thiab qhov ceev dua. Ntawm qhov tod tes, rau cov granite uas muaj cov noob loj, cov khoom me me nyuaj rau sib sau ua ke thiab muaj ntau qhov chaw me me, ua rau qhov ceev tsawg dua.
Qib ntawm kev nruj ntawm cov qauv
Granite uas muaj cov qauv me me muaj cov khoom me me uas sib xyaw ua ke zoo heev thiab yuav luag tsis muaj qhov khoob pom tseeb. Cov qauv no pab ua kom muaj qhov ntom ntom. Txawm li cas los xij, cov granite uas tsis muaj cov qauv xoob, vim yog kev sib xyaw ua ke ntawm cov khoom me me, muaj qhov chaw loj thiab ntuj tsim muaj qhov ntom ntom qis dua. Piv txwv li, granite uas muaj cov qauv ntom ntom uas tsim los ntawm cov txheej txheem geological tshwj xeeb muaj qhov ntom ntom sib txawv ntau dua li nws cov qauv xoob.
III. Qib ntawm Crystallization
Thaum lub sijhawm tsim cov granite, thaum qhov kub thiab siab hloov pauv, cov pob zeb siv lead ua yuav maj mam crystallize. Granite nrog qib siab ntawm crystallization muaj kev teeb tsa crystal zoo dua thiab compact, thiab qhov sib txawv ntawm cov siv lead ua me dua. Yog li ntawd, nws muaj qhov hnyav ntau dua ib chav ntim thiab qhov ceev dua. Granite nrog qib qis ntawm crystallization muaj kev teeb tsa crystal tsis zoo dua thiab qhov sib txawv loj dua ntawm cov siv lead ua, ua rau qhov ceev qis dua.
Iv. Qhov Hnyuv thiab Kab Ntsig
Thaum lub sijhawm tsim thiab khawb granite, cov qhov thiab cov kab nrib pleb yuav tshwm sim. Qhov muaj cov qhov no txhais tau tias tsis muaj cov khoom khov kho hauv qhov no, uas yuav txo qhov hnyav tag nrho ntawm granite thiab yog li ntawd txo nws qhov ceev. Qhov ntau qhov thiab cov kab nrib pleb muaj, qhov loj dua lawv qhov loj me thiab qhov dav dua lawv qhov kev faib tawm, qhov pom tseeb dua qhov cuam tshuam ntawm kev txo qis ntawm qhov ceev yuav yog. Yog li ntawd, thaum xaiv cov ntaub ntawv granite, kev soj ntsuam seb puas muaj qhov pom tseeb thiab cov kab nrib pleb ntawm nws qhov chaw tuaj yeem siv ua qhov siv los ntsuas nws qhov ceev.
V. Tsim Ib Puag Ncig
Cov xwm txheej ib puag ncig geological sib txawv tuaj yeem ua rau muaj qhov sib txawv ntawm kev faib tawm thiab cov ntsiab lus ntawm cov zaub mov hauv granite, yog li cuam tshuam rau nws qhov ceev. Piv txwv li, granite tsim nyob rau hauv qhov kub thiab txias siab thiab siab siab muaj cov pob zeb ua kom tiav ntau dua, cov qauv compact dua, thiab tej zaum qhov ceev dua. Qhov ceev ntawm granite tsim nyob rau hauv ib puag ncig tsis hnyav yuav txawv. Tsis tas li ntawd, cov yam ntxwv ib puag ncig xws li kub, siab thiab noo noo kuj tuaj yeem cuam tshuam rau cov qauv thiab cov khoom siv hauv granite, cuam tshuam tsis ncaj qha rau nws qhov ceev.
Vi. Cov Txheej Txheem Ua Khoom
Cov txheej txheem siv hauv cov txheej txheem khawb av, xws li kev khawb av blasting, yuav ua rau muaj cov kab nrib pleb me me hauv cov granite, cuam tshuam rau nws cov qauv thiab tom qab ntawd muaj qee qhov cuam tshuam rau nws qhov ceev. Kev tsoo, sib tsoo thiab lwm txoj hauv kev thaum lub sijhawm ua cov txheej txheem kuj tseem tuaj yeem hloov pauv lub xeev thiab cov qauv ntawm granite, yog li cuam tshuam rau nws qhov ceev. Thaum lub sijhawm thauj mus los thiab khaws cia, cov txheej txheem ntim khoom tsis raug lossis cov chaw khaws cia hnyav yuav ua rau granite raug zawm, sib tsoo lossis lwj, uas kuj tseem yuav cuam tshuam rau nws qhov ceev.
Xaus lus, thaum xaiv cov ntaub ntawv granite, nws yog ib qho tsim nyog yuav tsum xav txog ntau yam uas cuam tshuam rau qhov ceev uas tau hais los saum toj no kom thiaj li ntsuas tau lawv cov kev ua tau zoo thiab xaiv cov ntaub ntawv granite tsim nyog tshaj plaws rau cov xwm txheej thov tshwj xeeb.
