Mu kuwerengera kolondola, kuyera kwa zinthu ndikofunikira kwambiri kuposa momwe ogula ambiri amazindikira. Mukasankha zida zomwe ziyenera kuyeza kulekerera kwa mainchesi ang'onoang'ono, katundu aliyense wazinthu amathandizira zolinga zanu zolondola kapena amachita motsutsana nazo. Chinthu chimodzi chomwe sichikambidwa mokwanira pogula zokambirana ndi porosity - ndipo kusiyana pakati pa granite yokhala ndi porous ndi zero-porosity ndi kwakukulu.
Nkhaniyi ikufotokoza chifukwa chake granite yopanda porosity yakhala chinthu chofunikira kwambiri pa zida zoyezera molondola, komanso tanthauzo la izi pa magwiridwe antchito a zida zanu, ndalama zoyezera, komanso chidaliro cha nthawi yayitali pakuyeza.
Kumvetsetsa Porosity mu Granite
Granite wachilengedwe, monga momwe ulili padziko lapansi, uli ndi ming'alu ndi mipata yaying'ono pakati pa tinthu ta mchere ta kristalo. Ma ming'alu amenewa amasiyana kukula kuyambira mipata yooneka mpaka nyumba zomwe zimangowoneka pang'onopang'ono. Mabuloko wamba a granite nthawi zambiri amakhala ndi ming'alu yomwe, ngakhale siivuta pa ntchito zomanga, imayambitsa nkhawa zazikulu pa kuwerengera kolondola.
Vuto ndi kuyamwa kwa chinyezi ndi kuipitsidwa. Mu chinthu chokhala ndi mabowo, madzi—madzi, mafuta, zosungunulira zotsukira, ngakhale mafuta ochokera m'manja opanda kanthu—amatha kulowa pansi pa nthaka. Zinthuzi zikalowa mkati, zimayambitsa mavuto angapo. Zimakhudza kukhazikika kwa mawonekedwe pamene kutentha kumasintha. Zimapanga kusiyana kwa kuuma kwa pamwamba. Zitha kusuntha kupita kunja panthawi yogwiritsidwa ntchito, kusiya zotsalira pazida zogwirira ntchito kapena kuipitsa malo oyesera ovuta.
Granite yopanda ma porosity yakonzedwa kuti ichotse ma voids amkati awa. Zotsatira zake ndi zinthu zokhuthala, zofanana komwe kapangidwe ka kristalo kamakhala kopitilira mkati, popanda malo amkati omwe angasunge zodetsa kapena kusunga chinyezi.
Momwe Zero-Porosity Imapezekera
Kuti granite isagwere bwino, pamafunika kukonza mwapadera. Njira yodziwika bwino imaphatikizapo kuyika vacuum ndi epoxy kapena ma resin ena oyenera.
