Asayansi ochokera ku Germany ndi Netherlands akufufuza zatsopano zosunga zachilengedwePLAzipangizo. Cholinga chake ndi kupanga zida zokhazikika zogwiritsa ntchito kuwala monga zowunikira zamagalimoto, ma lens, mapulasitiki owunikira kapena maupangiri owunikira. Pakadali pano, mankhwalawa amapangidwa ndi polycarbonate kapena PMMA.
Asayansi akufuna kupeza pulasitiki yopangidwa ndi bio kuti apange nyali zamagalimoto. Zikuoneka kuti asidi polylactic ndi oyenera ofuna zinthu.
Kupyolera mu njirayi, asayansi athetsa mavuto angapo omwe amakumana nawo ndi mapulasitiki achikhalidwe: choyamba, kutembenukira kuzinthu zongowonjezwdwa kungathe kuchepetsa mavuto omwe amadza chifukwa cha mafuta osakanizika pamakampani apulasitiki; chachiwiri, chingachepetse mpweya wa carbon dioxide; chachitatu, ichi Chimaphatikizapo kulingalira za moyo wonse wa zinthu.
"Sikuti polylactic acid imakhala ndi ubwino wokhazikika, imakhalanso ndi zinthu zabwino kwambiri za kuwala ndipo ingagwiritsidwe ntchito pazithunzi zowoneka bwino za mafunde a electromagnetic," anatero Dr. Klaus Huber, pulofesa pa yunivesite ya Paderborn ku Germany.
Pakalipano, chimodzi mwazovuta zomwe asayansi akugonjetsa ndikugwiritsa ntchito polylactic acid m'madera okhudzana ndi LED. LED imadziwika ngati gwero lounikira bwino komanso losamalira zachilengedwe. "Makamaka, moyo wautali wautumiki ndi kuwala kowoneka bwino, monga kuwala kwa buluu kwa nyali za LED, kumapangitsa kuti pakhale zofunikira kwambiri pazida," akufotokoza Huber. Ichi ndichifukwa chake zinthu zolimba kwambiri ziyenera kugwiritsidwa ntchito. Vuto ndilakuti: PLA imakhala yofewa pafupifupi madigiri 60. Komabe, magetsi a LED amatha kutentha mpaka madigiri 80 akugwira ntchito.
Vuto linanso lovuta ndi crystallization ya polylactic acid. Polylactic acid imapanga ma crystallites pafupifupi madigiri 60, omwe amasokoneza zinthuzo. Asayansi ankafuna kupeza njira kupewa crystallization; kapena kupanga ndondomeko ya crystallization kuti ikhale yowongoka - kotero kuti kukula kwa crystallites komwe kunapangidwa sikungakhudze kuwala.
Mu labotale ya Paderborn, asayansi adazindikira koyamba ma molekyulu a polylactic acid kuti asinthe zinthu zakuthupi, makamaka kusungunuka kwake komanso crystallization. Huber ali ndi udindo wofufuza momwe zowonjezera, kapena mphamvu zama radiation, zimatha kusintha zinthu. "Tinapanga njira yaing'ono yobalalitsira kuwala kwapang'onopang'ono makamaka kuti tiphunzire kupanga kristalo kapena kusungunuka, njira zomwe zimakhudza kwambiri ntchito ya kuwala," adatero Huber.
Kuphatikiza pa chidziwitso cha sayansi ndi luso, polojekitiyi ikhoza kupereka phindu lalikulu pazachuma pambuyo pa kukhazikitsidwa. Gululi likuyembekeza kupereka mayankho ake oyamba kumapeto kwa 2022.
