Ndizochitika zofala kwambiri. Misewu yowonongeka, yodzaza ndi maenje, ikukankhira kugwirizana kwa nthaka mpaka malire ndi kuwavula msanga msanga. Kapenanso kutsogolera ku mapeto ake, kaya ndi punctures ndi kuphulika matayala, kapena kuonongeka shock absorber.
Mtengo wake ndi wokwera, kwa madalaivala, omwe akukumana ndi ngongole zambiri zokonza, komanso kwa ma municipalities ndi mabungwe ena, omwe amayenera kukonza kapena kumanganso misewu yomweyi.
Tsopano, ofufuza ku Switzerland afika pa yankho lomwe likuwoneka ngati matsenga ... wakuda, ngati kamvekedwe ka phula. Iwo adatha kupanga misewu yokhoza kudzikonza yokha, kuteteza mapangidwe a maenje owonongeka. Koma si zamatsenga, koma sayansi yabwino, pogwiritsa ntchito nano-teknoloji kuti athetse vuto lomwe lakhalapo kuyambira pamene msewu wopangidwa unapangidwa.
Kodi zingatheke bwanji kuti msewu udzikonzere wokha?
Choyamba tiyenera kudziwa momwe mabowo amapangidwira. Asphalt yomwe msewuwu umapangidwira imakumana ndi kupsinjika kwakukulu kwamafuta ndi makina, osatchulanso kuwonekera nthawi zonse kuzinthu. Zinthu izi zimakankhira zinthuzo mpaka malire, kutulutsa ming'alu yaying'ono, yomwe imakula pakapita nthawi mpaka imasiya kukhala ming'alu ndikumaliza kukhala mabowo.
Ndiko kuti, ngati tilepheretsa kupanga ming'alu, tidzapewa kupanga mabowo. Monga? Chinsinsicho chiri mu phula - zinthu zakuda zomangira za viscous, zomwe zimachokera ku mafuta osakanizika, omwe amasunga zinthu zonse zomwe zimagwiritsidwa ntchito mu asphalt.
Kwa odziwika bwino phula, yeniyeni kuchuluka kwa chitsulo okusayidi nanoparticles anawonjezedwa kuti zimatsimikizira kukonza katundu. Izi zikakumana ndi mphamvu ya maginito zimatenthetsa. Ndipo amatenthetsa mpaka kusungunula phula, motero amadzaza ming'alu iliyonse.
Etienne Jeoffroy, ETH Zurich ndi Empa Complex Materials LaboratoryLingaliro ndiloti ma nano-particles asakanizidwe ndi binder [...] ndikuwotcha mpaka akuyenda pang'onopang'ono ndikutseka ming'alu.
Njira yothetsera vutoli sikulepheretsa kupanga ming'alu yokha. Mwa kuyankhula kwina, zikanakakamiza msewu kuti uwoneke, nthawi ndi nthawi, ku mphamvu ya maginito kuti zinthu zokonzanso zinthuzo zigwire ntchito. Malinga ndi ofufuza, zingakhale zokwanira kamodzi pachaka kutsimikizira kuti njira yothetsera vutoli ikugwira ntchito. Ndipo chabwino kwambiri, kutalika kwa msewu ukhoza kuwonjezedwa m'nthawi, mpaka kuwirikiza kawiri kuposa momwe zilili pano.
Kukhala ndi moyo wautali, kuchepetsa mtengo wanthawi yayitali. Komanso luso latsopano kapena zida zatsopano sizikanafunikira kuti apange misewu, popeza ma nano-particles amawonjezeredwa panthawi yokonzekera phula.
Pofuna kuwonetsa mseu ku mphamvu ya maginito, ofufuza akuganiza kuti magalimoto azikhala ndi zozungulira zazikulu, mwachitsanzo, majenereta a mphamvu yamagetsi yamagetsi. Ikafika nthawi yokonza msewu, umakhala wotsekedwa kwa maola angapo, zomwe zimalola majenereta ozungulirawa kuti azizungulira.
Kuti yankho likhale logwira ntchito mokwanira, msewu uyenera kumangidwa ndi zinthu izi kuyambira pachiyambi. Komabe, sizimalepheretsa kuti isagwiritsidwe ntchito m'misewu yomwe ilipo, monga Jeoffroy akunena kuti: "Tikhoza kukhala ndi nano-particles mu kusakaniza ndikugwiritsanso ntchito mphamvu ya maginito, kukwaniritsa kutentha koyenera kugwirizanitsa zinthu zatsopano ndi za njira yomwe ilipo."
Cholinga cha gululi tsopano ndikupeza mabizinesi omwe angathe kukulitsa dongosololi ndikupeza njira yotsika mtengo kwambiri yogwiritsira ntchito.
