Monga tonse tikudziwa, nsangalabwi ndi chinthu chabwino kwambiri.Mabanja ambiri amagwiritsa ntchito nsangalabwi pokongoletsa, ndipo nsangalabwi ili ndi nsangalabwi yachilengedwe ndi miyala yamtengo wapatali.Izi ndizofala kwambiri.Ndipo kaya ndi nsangalabwi yokumba kapena nsangalabwi zachilengedwe zili ndi ubwino wake ndi kuipa kwake.

Mawu Oyamba

Mwala Wopanga ndi kugwiritsa ntchito macadam wamwala wachilengedwe kapena granite kukhala zinthu zodzaza, zokhala ndi simenti, gesso ndi unsaturated polyester resin kuti zikhale zomatira, ndipo zimapangidwa ndi kusonkhezera, kugaya ndi kupukuta.

Mwala wachilengedwe wa marble ndi thanthwe la metamorphic lomwe limapangidwa ndi kutentha kwakukulu komanso kuthamanga kwakukulu mu crust.Imapangidwa makamaka ndi calcite, miyala yamchere, serpentine ndi dolomite.

Ubwino wa nsangalabwi zachilengedwe ndi kukongoletsa chitsanzo chikhalidwe, kumva bwino pambuyo kupukuta ndi kuuma ndi wamphamvu.Kufuna kuvala kukana kwambiri kuposa scagliola, osaopa kuyika utoto.Kuyipa kwa nsangalabwi yachilengedwe ndikuti singakhale wopanda msoko ndipo njere zomwe zili pamalo olumikizira sizingagwirizane.Mwala wachilengedwe ndi wopepuka komanso wovuta kukonza.

Ubwino wa nsangalabwi yokumba ndi mitundu yosiyanasiyana.Kulumikizana kwa nsangalabwi sikuonekeratu kotero kuti pali kukhulupirika kolimba.Imasinthasintha kwambiri kuposa miyala yachilengedwe.Miyala yopangidwa ndi mankhwala ndi mankhwala, kuuma kwake ndi kochepa, kosavuta kukanda komanso kuwononga. .
