Bo-rasaense ba tsoang Jeremane le Netherlands ba ntse ba etsa lipatlisiso ka lintho tse ncha tse sireletsang tikolohoPLAthepa. Sepheo ke ho ntshetsa pele thepa e tsitsitseng bakeng sa ditshebediso tsa mabone tse kang mabone a koloi, dilense, dipolasetiki tse bontshang lesedi kapa ditataiso tsa mabone. Hajoale, dihlahiswa tsena hangata di entswe ka polycarbonate kapa PMMA.
Bo-rasaense ba batla ho fumana polasetiki e thehiloeng linthong tsa tlhaho ho etsa mabone a koloi. Ho ile ha fumaneha hore polylactic acid ke thepa e loketseng.
Ka mokhoa ona, bo-rasaense ba rarollotse mathata a 'maloa a tobaneng le polasetiki ea setso: ea pele, ho lebisa tlhokomelo ea bona mehloling e nchafatsoang ho ka fokotsa khatello e bakoang ke oli e tala indastering ea polasetiki ka katleho; ea bobeli, e ka fokotsa mosi oa carbon dioxide; ea boraro, sena se kenyelletsa ho nahana ka potoloho eohle ea bophelo ba thepa.
“Esiti ea polylactic ha e na melemo feela mabapi le ho tšoarella, hape e na le thepa e ntle haholo ea optical 'me e ka sebelisoa maemong a bonahalang a maqhubu a motlakase,” ho bolela Ngaka Klaus Huber, moprofesa Univesithing ea Paderborn Jeremane.
Hona jwale, e 'ngoe ea mathata ao bo-rasaense ba a hlolang ke ho sebelisoa ha polylactic acid masimong a amanang le LED. LED e tsejoa e le mohloli oa leseli o sebetsang hantle le o mosa tikolohong. "Haholo-holo, bophelo bo bolelele ba tšebeletso le mahlaseli a bonahalang, joalo ka leseli le leputsoa la mabone a LED, li beha litlhoko tse phahameng thepa ea optical," ho hlalosa Huber. Ke ka lebaka leo thepa e tšoarellang haholo e lokelang ho sebelisoa. Bothata ke hore: PLA e ba bonolo ka likhato tse ka bang 60. Leha ho le joalo, mabone a LED a ka fihla mochesong o fihlang likhatong tse 80 ha a ntse a sebetsa.
Bothata bo bong bo phephetsang ke ho kristaletsoa ha polylactic acid. Polylactic acid e etsa likristale ka mocheso o ka bang likhato tse 60, tse fifatsang thepa. Bo-rasaense ba ne ba batla ho fumana mokhoa oa ho qoba ho kristaletsoa hona; kapa ho etsa hore ts'ebetso ea kristale e laolehe haholoanyane - e le hore boholo ba likristale tse entsoeng bo se ke ba ama leseli.
Laboratoring ea Paderborn, bo-rasaense ba ile ba qala ka ho fumana litšobotsi tsa limolek'hule tsa polylactic acid e le ho fetola litšobotsi tsa thepa, haholo-holo boemo ba eona ba ho qhibiliha le ho kristaleha ha eona. Huber o ikarabella bakeng sa ho batlisisa hore na li-additives, kapa matla a mahlaseli, li ka ntlafatsa litšobotsi tsa thepa hakae. "Re hahile sistimi ea ho hasanya leseli la sekhutlo se senyenyane ka ho khetheha bakeng sa sena ho ithuta ho thehoa ha kristale kapa lits'ebetso tsa ho qhibiliha, lits'ebetso tse nang le tšusumetso e kholo mosebetsing oa mahlo," ho boletse Huber.
Ntle le tsebo ea saense le ea tekheniki, projeke ena e ka fana ka melemo e meholo ea moruo kamora ho kenngoa tšebetsong. Sehlopha se lebeletse ho fana ka leqephe la sona la pele la likarabo qetellong ea 2022.
