Hauv kev ua granite, kev ntseeg tau ntawm lub tshuab yog qhov tseem ceeb tshaj plaws. Cov khoom siv granite ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom siv ua haujlwm tau zoo thiab ua haujlwm tau zoo. Los ntawm kev nqis peev rau cov khoom siv granite zoo, cov lag luam tuaj yeem txhim kho kev ntseeg tau ntawm lawv cov tshuab, yog li ua rau muaj kev tsim khoom ntau dua thiab txo lub sijhawm tsis ua haujlwm.
Ib qho ntawm cov ua rau lub tshuab ua haujlwm tsis zoo hauv kev ua granite yog kev hnav cov khoom. Granite yog cov khoom siv ntom thiab abrasive uas tuaj yeem ua rau cov tshuab puas tsuaj. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom siv ruaj khov thiab muaj zog tsim tshwj xeeb rau kev ua granite. Cov khoom siv tshuab granite zoo tau tsim los tiv taus cov xwm txheej nyuaj ntawm kev lag luam, kom ntseeg tau tias lub tshuab ua haujlwm ntawm qib zoo tshaj plaws rau lub sijhawm ntev.
Kev saib xyuas tas li thiab kev hloov cov khoom qub raws sijhawm kuj tseem ceeb heev rau kev txhim kho kev ntseeg siab ntawm lub tshuab. Los ntawm kev saib xyuas cov xwm txheej ntawm cov tshuab thiab hloov cov khoom ua ntej lawv ua tsis tiav, cov tuam txhab tuaj yeem tiv thaiv kev ua tsis tiav tsis tau xav txog los ntawm kev cuam tshuam kev tsim khoom. Txoj hauv kev ua ntej no tsis yog tsuas yog txuag lub sijhawm xwb tab sis kuj txo cov nqi kho, ua rau nws yog kev nqis peev ntse rau txhua lub lag luam ua granite.
Ntxiv mus, kev siv cov thev naus laus zis siab heev hauv cov khoom siv granite tau hloov pauv kev lag luam. Cov khoom siv niaj hnub feem ntau muaj cov yam ntxwv ua kom zoo dua xws li cov txheej txheem lubrication zoo dua thiab tiv taus cua sov zoo dua. Cov kev tsim kho tshiab no pab txhim kho kev ntseeg siab ntawm cov tshuab, ua rau muaj cov zis thiab zoo sib xws hauv kev ua granite.
Hauv kev xaus lus, qhov tseem ceeb ntawm cov khoom siv hauv tshuab granite hauv kev txhim kho kev ntseeg siab ntawm lub tshuab tsis tuaj yeem hais ntau dhau. Los ntawm kev xaiv cov khoom zoo, ua kev saib xyuas tsis tu ncua, thiab kev siv cov thev naus laus zis tshiab, cov lag luam tuaj yeem ua kom lawv cov tshuab khiav tau zoo thiab ntseeg tau. Qhov no yuav ua rau muaj kev tsim khoom ntau ntxiv, txo cov nqi thiab tau txais txiaj ntsig zoo hauv kev lag luam ua granite. Kev nqis peev rau hauv cov khoom zoo tsis yog ib qho kev xaiv xwb; nws yog qhov tsim nyog rau kev vam meej hauv kev lag luam no.
