Granite yog ib yam khoom siv nrov rau kev ua cov khoom siv tshuab vim nws qhov tawv, ruaj khov thiab tiv taus kev hnav thiab rhuav. Txawm li cas los xij, tseem yuav muaj qhov tsis zoo hauv cov khoom siv tshuab granite uas tuaj yeem cuam tshuam rau lawv qhov zoo thiab kev ua haujlwm.
Ib qho ntawm cov teeb meem feem ntau hauv cov khoom siv granite yog cov kab nrib pleb. Cov no yog cov kab tawg lossis cov kab uas tshwm sim ntawm qhov chaw lossis sab hauv ntawm cov khoom vim muaj kev ntxhov siab, kev cuam tshuam lossis kev hloov pauv kub. Cov kab nrib pleb tuaj yeem ua rau cov khoom tsis muaj zog thiab ua rau nws tsis ua haujlwm sai.
Lwm qhov tsis zoo yog porosity. Cov khoom siv granite porous yog cov uas muaj cov hnab me me lossis cov qhov khoob hauv lawv. Qhov no tuaj yeem ua rau lawv tsis muaj zog thiab yooj yim tawg lossis tawg thaum muaj kev ntxhov siab. Porosity kuj tseem tuaj yeem cuam tshuam rau qhov tseeb ntawm qhov loj ntawm cov khoom, ua rau muaj qhov tsis raug hauv cov tshuab.
Qhov tsis zoo thib peb yog qhov tiav ntawm qhov chaw. Cov khoom siv tshuab granite tej zaum yuav muaj qhov tiav ntawm qhov chaw tsis sib npaug lossis ntxhib uas tuaj yeem cuam tshuam rau lawv txoj haujlwm. Qhov roughness tuaj yeem ua rau muaj kev sib txhuam thiab ua rau muaj kev hnav thiab tsim kua muag ntawm cov khoom. Nws kuj tseem tuaj yeem ua rau nws nyuaj rau mount lossis sib sau ua ke cov khoom kom raug.
Thaum kawg, qhov zoo ntawm cov granite siv kuj tuaj yeem cuam tshuam rau cov khoom. Cov granite tsis zoo yuav muaj cov khoom tsis huv lossis tsis sib xws uas tuaj yeem cuam tshuam rau nws qhov nyuaj, ruaj khov thiab hnav tsis kam. Qhov no tuaj yeem ua rau hloov thiab kho cov khoom siv tshuab ntau zaus.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov qhov tsis zoo no tuaj yeem txo qis lossis tshem tawm nrog cov txheej txheem tsim khoom zoo thiab kev ntsuas kev tswj hwm zoo. Piv txwv li, cov kab nrib pleb tuaj yeem tiv thaiv tau los ntawm kev siv cov granite zoo thiab tswj qhov kub thiab kev ntxhov siab thaum lub sijhawm ua haujlwm. Porosity tuaj yeem tshem tawm los ntawm kev siv cov txheej txheem nqus tsev kom sau cov voids nrog cov resin lossis polymer. Qhov tiav ntawm qhov chaw tuaj yeem txhim kho los ntawm kev txhuam thiab siv cov cuab yeej txiav precision.
Thaum kawg, cov khoom siv granite yog ib qho kev xaiv txhim khu kev qha thiab ruaj khov rau cov tshuab. Los ntawm kev ua kom muaj kev tsim khoom zoo thiab kev tswj xyuas zoo, qhov tsis zoo tuaj yeem txo qis thiab lub neej ntev thiab kev ua tau zoo ntawm cov khoom tuaj yeem ua kom siab tshaj plaws.
