Kuyika magetsi: Simenti yatsopano imapangitsa konkriti kupanga magetsi

Mainjiniya ochokera ku South Korea apanga kompositi yopangidwa ndi simenti yomwe ingagwiritsidwe ntchito mu konkire kuti ipange zinthu zomwe zimapanga ndikusunga magetsi pogwiritsa ntchito mphamvu zamakina akunja monga mapazi, mphepo, mvula ndi mafunde.

Posandutsa nyumba kukhala magwero amagetsi, simentiyo ithetsa vuto la malo omanga omwe amawononga 40% ya mphamvu zapadziko lonse lapansi, akukhulupirira.

Ogwiritsa ntchito zomangamanga sayenera kuda nkhawa kuti adzagwidwa ndi magetsi.Mayesero adawonetsa kuti 1% voliyumu ya ma conductive carbon fibers mu osakaniza a simenti inali yokwanira kupatsa simenti zinthu zamagetsi zomwe zimafunidwa popanda kusokoneza magwiridwe antchito, ndipo zomwe zidapangidwa pano zinali zotsika kwambiri kuposa momwe zimaloledwa mthupi la munthu.

Akatswiri ofufuza zamakina ndi zomangamanga ochokera ku Incheon National University, Kyung Hee University ndi Korea University adapanga simenti yopangidwa ndi ma conductive kompositi (CBC) yokhala ndi ulusi wa kaboni womwe ungakhalenso ngati triboelectric nanogenerator (TENG), mtundu wa makina okolola mphamvu.

Adapanga kapangidwe kake ka labu ndi capacitor yochokera ku CBC pogwiritsa ntchito zida zomwe zidapangidwa kuti ziyese mphamvu zake zokolola ndikusunga.

"Tinkafuna kupanga zida zopangira mphamvu zomwe zingagwiritsidwe ntchito pomanga mphamvu zopanda zero zomwe zimagwiritsa ntchito ndikupangira magetsi awo," adatero Seung-Jung Lee, pulofesa ku Incheon National University's Department of Civil and Environmental Engineering.

"Popeza simenti ndi chinthu chofunikira kwambiri pomanga, tidaganiza zoigwiritsa ntchito ndi zodzaza ma conductive ngati chinthu chofunikira kwambiri pamakina athu a CBC-TENG," adawonjezera.

Zotsatira za kafukufuku wawo zidasindikizidwa mwezi uno m'magazini ya Nano Energy.

Kupatula kusungirako mphamvu ndi kukolola, zinthuzo zitha kugwiritsidwanso ntchito kupanga makina odzimva okha omwe amayang'anira thanzi lamapangidwe ndikulosera moyo wotsalira wa zomanga za konkriti popanda mphamvu zakunja.

"Cholinga chathu chachikulu chinali kupanga zida zomwe zidapangitsa moyo wa anthu kukhala wabwino komanso zosafunikira mphamvu zowonjezera kuti zipulumutse dziko lapansi.Ndipo tikuyembekeza kuti zomwe zapeza kuchokera ku kafukufukuyu zitha kugwiritsidwa ntchito kukulitsa kugwiritsa ntchito kwa CBC ngati mphamvu zonse zopangira mphamvu za net-zero," adatero Prof. Lee.

Pofalitsa kafukufukuyu, Incheon National University inaseka kuti: "Zikuwoneka ngati kuyamba kosangalatsa kwa mawa kowala komanso kobiriwira!"
