Ndi chitukuko chofulumira chamakampani, mafelemu a nsangalabwi tsopano akugwiritsidwa ntchito kwambiri. Pambuyo pa ukalamba wazaka mamiliyoni ambiri, amakhala ndi mawonekedwe ofanana, okhazikika, olimba, olimba kwambiri, komanso olondola kwambiri, amatha kunyamula zinthu zolemera. Amagwiritsidwa ntchito kwambiri popanga mafakitale komanso kuyeza kwa labotale. Ndiye, ndi zolakwika zotani zomwe zimachitika posamalira mafelemu a nsangalabwi? M'munsimu muli kufotokoza mwatsatanetsatane.
1. Kutsuka ndi Madzi
Mafelemu a nsangalabwi, monga matabwa achilengedwe ndi mwala wachilengedwe, ndi zida za porous zomwe zimatha kupuma kapena kungomwa madzi ndikusungunula zowononga pomiza. Ngati mwala umatenga madzi ochulukirapo ndi zowononga, zofooka zosiyanasiyana zamwala zimatha kukhala, monga chikasu, kuyandama, dzimbiri, kusweka, kuyera, kukhetsa, mawanga amadzi, efflorescence, ndi kumaliza kwa matte.
2. Pewani kukhudzana ndi zinthu zopanda ndale
Miyala yonse imakhudzidwa ndi ma acid ndi alkalis. Mwachitsanzo, asidi nthawi zambiri imapangitsa kuti granite ikhale oxidize, zomwe zimapangitsa kuti pakhale mawonekedwe achikasu chifukwa cha okosijeni wa pyrite. Acidity imayambitsanso dzimbiri, zomwe zimalekanitsa calcium carbonate yomwe ili mu marble ndipo imapangitsa kuti pamwamba pakhale malire a tirigu a granite alkaline feldspar ndi quartz silicide. 3. Pewani kuphimba mafelemu a nsangalabwi ndi zinyalala kwa nthawi yaitali.
Kuonetsetsa kuti mwalawo ukupuma bwino, pewani kuuphimba ndi kapeti ndi zinyalala, chifukwa izi zimalepheretsa kuti chinyezi chisachoke pansi pa mwalawo. Mwala udzavutika ndi kuyabwa chifukwa cha chinyezi. Kuchuluka kwa chinyezi kungayambitse kupsa mtima. Ngati mukuyenera kuyala kapeti kapena zinyalala, onetsetsani kuti mwayeretsa bwino. Nthawi zonse gwiritsani ntchito chotolera fumbi ndi ma electrostatic traction pochotsa fumbi ndi kuyeretsa, kaya mukugwira ntchito ndi granite yolimba kapena mwala wofewa.
