Bo-rasaense ba tsoang Jeremane le Netherlands ba ntse ba etsa lipatlisiso tse ncha tse baballang tikolohoPLAlisebelisoa.Sepheo ke ho hlahisa lisebelisoa tse tšoarellang bakeng sa lisebelisoa tsa optical tse kang mabone a likoloi, lilense, li-plastiki tse khanyang kapa litataiso tse khanyang.Hajoale, lihlahisoa tsena hangata li entsoe ka polycarbonate kapa PMMA.
Bo-rasaense ba batla ho fumana polasetiki e thehiloeng ho bio ho etsa mabone a koloi.Hoa fumaneha hore acid ea polylactic ke lisebelisoa tse loketseng tsa mokhethoa.
Ka mokhoa ona, bo-rasaense ba rarolotse mathata a 'maloa a tobaneng le li-plastiki tsa setso: pele, ho lebisa tlhokomelo ea bona mehloling e tsosolositsoeng ho ka fokotsa ka katleho khatello e bakoang ke oli e sa hloekang indastering ea polasetiki;ea bobeli, e ka fokotsa ho ntšoa ha carbon dioxide;ea boraro, sena se Akarelletsa ho nahanela potoloho eohle ea bophelo ba lintho tse bonahalang.
Dr. Klaus Huber, moprofesa Univesithing ea Paderborn, Jeremane, o re: "Hase feela hore polylactic acid e na le melemo mabapi le ts'ebetso e tsitsitseng, e boetse e na le lisebelisoa tse ntle haholo tsa optical 'me e ka sebelisoa ka bongata bo bonahalang ba maqhubu a motlakase.
Hona joale, e 'ngoe ea mathata ao bo-rasaense ba a hlōlang ke ho sebelisoa ha polylactic acid masimong a amanang le LED.LED e tsejoa e le mohloli oa leseli o sebetsang hantle le o se nang tikoloho."Haholo-holo, bophelo bo bolelele ba tšebeletso le mahlaseli a bonahalang, a kang lebone le leputsoa la mabone a LED, a beha litlhoko tse phahameng ho lisebelisoa tsa optical," ho hlalosa Huber.Ke ka lebaka lena ho tlamehang ho sebelisoa thepa e tšoarellang haholo.Bothata ke: PLA e fetoha e bonolo hoo e ka bang likhato tse 60.Leha ho le joalo, mabone a LED a ka fihla mocheso o fihlang ho likhato tse 80 ha a ntse a sebetsa.
Bothata bo bong bo phephetsang ke crystallization ea polylactic acid.Polylactic acid e etsa likristale ka likhato tse ka bang 60, tse fifatsang thepa.Bo-rasaense ba ne ba batla ho fumana mokhoa oa ho qoba crystallization ena;kapa ho etsa hore ts'ebetso ea crystallization e laolehe haholoanyane - e le hore boholo ba li-crystallites tse entsoeng bo ke ke ba ama leseli.
Ka laboratoring ea Paderborn, bo-rasaense ba ile ba qala ka ho etsa qeto ea hore na limolek'hule tsa polylactic acid e le ho fetola thepa ea eona, haholo-holo boemo ba eona ba ho qhibiliha le kristale.Huber o na le boikarabello ba ho batlisisa hore na li-additives, kapa matla a mahlaseli a kotsi, a ka ntlafatsang thepa ea thepa."Re ile ra haha sistimi e nyenyane ea ho hasanya lebone ka ho khetheha bakeng sa sena ho ithuta ho thehoa ha kristale kapa mekhoa ea ho qhibiliha, mekhoa e nang le tšusumetso e kholo mosebetsing oa optical," ho boletse Huber.
Ho phaella tsebong ea saense le ea theknoloji, morero ona o ka fana ka melemo e mengata ea moruo ka mor'a hore e sebelisoe.Sehlopha se lebelletse ho fana ka leqephe la sona la pele la likarabo bofelong ba 2022.
