Pakalipano, penti zolembera misewu yakunja ndizochokera kumadzi kwambiri ndipo zimakula mwachangu. Zoposa 90% za penti zolembera misewu m'maiko otukuka monga United States, Germany, Spain, Sweden, ndi Finland amagwiritsa ntchito zopangira madzi. Chifukwa cha kuyambika koyambirira kwa zokutira zolembera zakunja ndi chitukuko chofulumira chaukadaulo, zokutira zolembera mumsewu wa nanometer, zokutira zolembera zamsewu zamagulu awiri, zokutira zopaka utoto zamtundu wamtundu, ndi zina zotero.
Miyezi ingapo kapena masiku angapo mutatha kupanga, padzakhala kusintha kwakukulu kwa mamasukidwe akayendedwe, kupukuta khungu, ndi zina zotero, zomwe zimapangitsa kuti kupopera mankhwala kusakhale bwino kwa ❖ kuyanika ndi kutsegula bwino; nthawi yosamata singathe kukwaniritsa zofunikira zenizeni zomanga misewu ndikukhudza zomangamanga Kuyenda bwino kwa magalimoto panthawiyo.
Panopa pali mafakitale akuluakulu ndi ang'onoang'ono oposa 100 opaka utoto ku China. Mafakitale akuluakulu angapo omwe ali ndi luso lamphamvu kwambiri ayambanso kupanga utoto wopangira misewu yotengera madzi. Pofuna kuonetsetsa kuti penti zolembera mumsewu zili bwino, unduna wa zamayendedwe wapanga mafakitale oyenerera. Miyezo ikulimbikitsa mwamphamvu zokutira zolembera mumsewu zamadzi. Kusanthula kwa akatswiri a zokutira pansi: Pakukula kwamakampani oyendera misewu ku China komanso kuchuluka kwa umwini wamagalimoto, kufunikira kwa zokutira kudzakwera. Ndi kuwonjezeka kwa kuzindikira kwa anthu za chitetezo cha chilengedwe ndi kuthandizira ndondomeko ndi malamulo a dziko, kufunikira kwa zokutira zolembera zolembera madzi mumsewu Kuchuluka kwake ndi kwakukulu.
Zopangira zopenta zapamadzi za mdziko langa zagwiritsidwa ntchito pomanga mabwalo a ndege, misewu yayikulu, ndi ntchito zina, zomwe zidavumbulutsanso zovuta zina zaukadaulo. Mavuto apano a zotchingira zounikira zonyezimira m'madzi zotengera madzi ndi monga: kusapsa bwino komanso kusasunthika kwa nyengo, ndipo ziyenera kulumikizidwanso pakapita nthawi 1a; kusakanizika kwa madzi ndi kukana kwa alkali, osatha kukwaniritsa zofunikira zenizeni zakuyenda pamsewu m'madzi; osauka banga kukana, ndi pamwamba chizindikiro n'zosavuta kudziunjikira fumbi. Kukhudza retroreflective coefficient ndi kuchepetsa chonyezimira zotsatira; kusakhazikika kosungirako.
