Ma granite pamwamba ndi zida zina zoyezera molondola zimapangidwa ndi granite yapamwamba kwambiri. Komabe, si mitundu yonse ya granite yoyenera kupanga zida izi zolondola. Kuti zitsimikizire kulimba, kukhazikika, komanso kulondola kwa ma granite pamwamba, zinthu zopangira granite ziyenera kukwaniritsa zofunikira zina. Pansipa pali makhalidwe ofunikira omwe granite iyenera kukhala nawo kuti igwiritsidwe ntchito popanga ma granite pamwamba ndi zida zina zoyezera.
1. Kuuma kwa Granite
Kuuma kwa granite ndi chimodzi mwazinthu zofunika kwambiri posankha zinthu zopangira mbale za granite pamwamba. Granite yomwe imagwiritsidwa ntchito pazida zolondola iyenera kukhala ndi kuuma kwa Shore kwa pafupifupi madigiri 70. Kuuma kwakukulu kumatsimikizira kuti pamwamba pa granite pamakhalabe yosalala komanso yolimba, zomwe zimapangitsa kuti pakhale malo oyezera okhazikika komanso odalirika.
Kuphatikiza apo, mosiyana ndi chitsulo chopangidwa ndi chitsulo, granite imalimbana ndi dzimbiri ndi dzimbiri, zomwe zimapangitsa kuti ikhale yabwino kwambiri pamalo omwe ali ndi chinyezi chambiri kapena kusinthasintha kwa kutentha. Kaya imagwiritsidwa ntchito ngati mbale yowunikira granite kapena ngati tebulo logwirira ntchito, granite imatsimikizira kuyenda kosalala popanda kukangana kapena kumamatira kosafunikira.
2. Mphamvu Yokoka ya Granite
Granite ikakwaniritsa kuuma kofunikira, mphamvu yake yokoka (kapena kuchuluka kwake) ndiye chinthu china chofunikira kwambiri. Granite yomwe imagwiritsidwa ntchito popanga mbale zoyezera iyenera kukhala ndi mphamvu yokoka pakati pa 2970–3070 kg/m³. Granite ili ndi mphamvu yochulukirapo, zomwe zimapangitsa kuti kutentha kwake kukhale kolimba. Izi zikutanthauza kuti mbale za granite pamwamba sizingakhudzidwe kwambiri ndi kusintha kwa kutentha kapena chinyezi, zomwe zimapangitsa kuti zitsimikizire kulondola komanso kulondola panthawi yoyezera. Kukhazikika kwa zinthuzo kumathandiza kupewa kusintha kwa kutentha, ngakhale m'malo omwe kutentha kumasinthasintha.
3. Mphamvu Yokakamiza ya Granite
Granite yomwe imagwiritsidwa ntchito popanga zida zoyezera molondola iyeneranso kuwonetsa mphamvu yayikulu yopondereza. Mphamvu imeneyi imatsimikizira kuti granite imatha kupirira kupsinjika ndi mphamvu zomwe zimagwiritsidwa ntchito poyezera popanda kupindika kapena kusweka.
Chiŵerengero cha kukula kwa granite ndi 4.61 × 10⁻⁶/°C, ndipo kuchuluka kwake koyamwa madzi ndi kochepera 0.13%. Zinthu zimenezi zimapangitsa granite kukhala yoyenera kwambiri popanga mbale za granite pamwamba ndi zida zina zoyezera. Mphamvu yolimba kwambiri komanso kuyamwa madzi pang'ono kumatsimikizira kuti zinthuzo zimasunga kulondola kwake komanso kusalala pakapita nthawi, ndipo sizikufunika kukonza kwambiri.
Mapeto
Granite yokha yokhala ndi makhalidwe oyenera—monga kuuma kokwanira, mphamvu yokoka, ndi mphamvu yokakamiza—ndiyo ingagwiritsidwe ntchito kupanga mbale zapamwamba za granite ndi zida zoyezera zolondola kwambiri. Zipangizozi ndizofunikira kwambiri kuti zitsimikizire kulondola kwa nthawi yayitali, kulimba, komanso kugwira ntchito bwino kwa zida zanu zoyezera zolondola. Mukasankha granite popanga zida zoyezera, ndikofunikira kuonetsetsa kuti zopangirazo zikukwaniritsa zofunikira izi.
