Nrog kev loj hlob sai ntawm kev lag luam, cov thav duab txaj marble tam sim no tau siv dav. Tom qab ntau lab xyoo ntawm kev laus, lawv muaj cov qauv zoo sib xws, kev ruaj khov zoo heev, lub zog, kev tawv siab, thiab kev raug siab, muaj peev xwm tuav cov khoom hnyav. Lawv tau siv dav hauv kev tsim khoom lag luam thiab kev ntsuas hauv chaw kuaj mob. Yog li, qee qhov yuam kev feem ntau thaum tswj cov thav duab txaj marble yog dab tsi? Hauv qab no yog cov lus piav qhia ntxaws ntxaws.
1. Ntxuav nrog dej
Cov thav duab txaj marble, zoo li ntoo ntuj thiab pob zeb ntuj, yog cov khoom siv uas muaj qhov ntxeem tau uas tuaj yeem ua pa lossis tsuas yog nqus dej thiab yaj cov pa phem los ntawm kev raus. Yog tias lub pob zeb nqus dej thiab cov pa phem ntau dhau, ntau yam teeb meem ntawm pob zeb tuaj yeem tshwm sim, xws li daj, ntab, xeb, tawg, dawb, poob, dej tawm, tawm xim, thiab tiav matte.
2. Tsis txhob kov cov khoom tsis yog nruab nrab
Txhua lub pob zeb muaj kev rhiab heev rau cov kua qaub thiab cov alkalis. Piv txwv li, cov kua qaub feem ntau ua rau granite oxidize, ua rau pom xim daj vim yog pyrite oxidation. Cov kua qaub kuj ua rau xeb, uas cais cov calcium carbonate uas muaj nyob hauv marble thiab ua rau qhov chaw cais cov ciam teb ntawm granite's alkaline feldspar thiab quartz silicide. 3. Tsis txhob npog cov thav duab marble nrog cov khib nyiab rau lub sijhawm ntev.
Yuav kom lub pob zeb ua pa tau zoo, tsis txhob npog nws nrog cov ntaub pua plag thiab cov khib nyiab, vim qhov no tiv thaiv cov dej noo kom tsis txhob evaporate los ntawm hauv qab lub pob zeb. Lub pob zeb yuav raug kev khaus vim yog cov dej noo. Cov dej noo ntau ntxiv tuaj yeem ua rau khaus. Yog tias koj yuav tsum tso cov ntaub pua plag lossis cov khib nyiab, nco ntsoov ntxuav nws kom huv si. Siv cov khoom siv plua plav thiab electrostatic traction tsis tu ncua rau kev tshem tawm cov plua plav thiab kev ntxuav, txawm tias ua haujlwm nrog granite khov kho lossis marble mos.
