Chifukwa cha kukula kwa mafakitale mwachangu, mafelemu a bedi la marble tsopano akugwiritsidwa ntchito kwambiri. Pambuyo pa zaka mamiliyoni ambiri akukalamba, ali ndi kapangidwe kofanana, kukhazikika bwino, mphamvu, kuuma kwambiri, komanso kulondola kwambiri, amatha kunyamula zinthu zolemera. Amagwiritsidwa ntchito kwambiri popanga mafakitale komanso poyesa labotale. Ndiye, ndi zolakwika ziti zomwe zimachitika kawirikawiri pokonza mafelemu a bedi la marble? Pansipa pali kufotokozera mwatsatanetsatane.
1. Kutsuka ndi Madzi
Mafelemu a miyala yamtengo wapatali, monga matabwa achilengedwe ndi miyala yachilengedwe, ndi zinthu zokhala ndi mabowo zomwe zimatha kupuma kapena kungoyamwa madzi ndikusungunula zodetsa pozimiza. Ngati mwalawo utenga madzi ambiri ndi zodetsa, zolakwika zosiyanasiyana za miyala zimatha kuchitika, monga chikasu, kuyandama, dzimbiri, ming'alu, kuyera, kutayika, madontho a madzi, kuwala kwa dzuwa, ndi kutha kwa matte.
2. Pewani kukhudzana ndi zinthu zosakhudzana ndi mpweya
Miyala yonse imakhala yogwirizana ndi ma acid ndi ma alkali. Mwachitsanzo, asidi nthawi zambiri amachititsa kuti granite isungunuke, zomwe zimapangitsa kuti iwoneke yachikasu chifukwa cha pyrite oxidation. Asidi imayambitsanso dzimbiri, zomwe zimalekanitsa calcium carbonate yomwe ili mu marble ndipo zimapangitsa kuti pamwamba pa granite pakhale kusiyana pakati pa malire a alkaline feldspar ndi quartz silicide. 3. Pewani kuphimba mafelemu a marble ndi zinyalala kwa nthawi yayitali.
Kuti mwalawo ukhale wosalala, pewani kuuphimba ndi kapeti ndi zinyalala, chifukwa izi zimaletsa chinyezi kuti chisatuluke pansi pa mwalawo. Mwalawo udzavutika ndi kukwiya chifukwa cha chinyezi. Kuchuluka kwa chinyezi kungayambitse kukwiya. Ngati muyenera kuyika kapeti kapena zinyalala, onetsetsani kuti mwayeretsa bwino. Nthawi zonse gwiritsani ntchito chosonkhanitsira fumbi ndi mphamvu zamagetsi pochotsa fumbi ndi kuyeretsa, kaya pogwiritsa ntchito granite yolimba kapena marble yofewa.
