Nrog rau txoj kev loj hlob sai ntawm kev lag luam, marble txaj thav ntawv yog tam sim no dav siv. Tom qab ntau lab xyoo ntawm kev laus, lawv muaj ib qho kev ntxhib los mos, zoo heev stability, lub zog, siab hardness, thiab siab precision, muaj peev xwm tuav cov khoom hnyav. Lawv yog dav siv nyob rau hauv industrial ntau lawm thiab kuaj ntsuas. Yog li, dab tsi yog qee qhov yuam kev thaum tuav marble txaj thav ntawv? Hauv qab no yog cov lus piav qhia ntxaws.
1. Npog nrog dej
Marble txaj thav ntawv, zoo li ntoo thiab ntuj pob zeb, yog cov khoom ntxeem tau uas ua pa los yog yooj yim nqus dej thiab yaj cov kab mob los ntawm kev immersion. Yog tias lub pob zeb nqus dej ntau dhau thiab cov khoom paug, ntau yam pob zeb tsis xws luag tuaj yeem tsim, xws li yellowing, ntab, xeb, tawg, whitening, shedding, dej me ntsis, efflorescence, thiab matte tiav.
2. Tsis txhob sib cuag nrog cov ntaub ntawv uas tsis yog nruab nrab
Tag nrho cov pob zeb yog rhiab heev rau acids thiab alkalis. Piv txwv li, acid feem ntau ua rau granite rau oxidize, ua rau yellowish tsos vim pyrite oxidation. Acidity kuj ua rau corrosion, uas cais cov calcium carbonate uas muaj nyob rau hauv marble thiab ua rau saum npoo cais cov ciam teb ntawm granite alkaline feldspar thiab quartz silicide. 3. Tsis txhob npog marble txaj thav ntawv nrog cov khib nyiab rau lub sijhawm ntev.
Txhawm rau kom lub pob zeb ua pa du, tsis txhob npog nws nrog cov ntaub pua plag thiab cov khib nyiab, vim qhov no tiv thaiv cov dej noo los ntawm evaporating hauv qab pob zeb. Lub pob zeb yuav raug kev txom nyem los ntawm kev kub nyhiab vim ya raws. Cov dej noo ntau ntxiv tuaj yeem ua rau khaus. Yog tias koj yuav tsum nteg cov ntaub pua plag lossis cov khib nyiab, nco ntsoov ntxuav nws kom huv. Tsis tu ncua siv cov plua plav collector thiab electrostatic traction rau cov plua plav tshem tawm thiab ntxuav, txawm tias ua haujlwm nrog cov khoom siv granite lossis mos marble.
