Masayendisiti anobva kuGermany neNetherlands ari kutsvagisa hutsva hunoenderana nemhoteredzoPLAzvinhu.Chinangwa ndechekugadzira zvinhu zvinogoneka zvekushandisa optical senge mota dzemwenje, lenzi, mapurasitiki anopenya kana madhairekitori.Parizvino, zvigadzirwa izvi zvinowanzogadzirwa ne polycarbonate kana PMMA.
Masayendisiti anoda kutsvaga bio-based plastic kugadzira marambi emota.Zvinoitika kuti polylactic asidhi ndiyo yakakodzera mumiriri zvinhu.
Kuburikidza nenzira iyi, masayendisiti akagadzirisa matambudziko akati wandei akatarisana nemapurasitiki echinyakare: kutanga, kutendeudzira pfungwa dzavo kune zvinogona kudzokororwa zviwanikwa zvinogona kunyatso kudzikisa kumanikidzwa kunokonzerwa nemafuta asina kuchena paindasitiri yepurasitiki;chechipiri, inogona kuderedza kubudiswa kwecarbon dioxide;chechitatu, izvi Zvinosanganisira kutariswa kwehupenyu hwese hwezvinhu.
"Hakusi chete kuti polylactic acid ine zvakanakira maererano nekugadzikana, inewo yakanaka kwazvo optical properties uye inogona kushandiswa mumagetsi anooneka emagetsi emagetsi," anodaro Dr. Klaus Huber, purofesa paYunivhesiti yePaderborn muGermany.
Parizvino, imwe yezvinetso izvo masayendisiti ari kukunda ndeyekushandiswa kwepolylactic acid muminda ine hukama ne LED.LED inozivikanwa seyakajeka uye ine hushamwari mwenje sosi."Kunyanya, hupenyu hurefu hwesevhisi uye nemwaranzi inooneka, senge mwenje webhuruu wemarambi e LED, inoisa zvakanyanya kudiwa pazvinhu zvemaziso," anotsanangura Huber.Ichi ndicho chikonzero zvinhu zvakasimba zvakanyanya zvinofanira kushandiswa.Dambudziko nderekuti: PLA inova yakapfava pakutenderedza 60 madhigirii.Nekudaro, mwenje we LED unogona kusvika tembiricha yakakwira se80 madhigirii uchishanda.
Imwe dambudziko rakaoma ndeye crystallization ye polylactic acid.Polylactic asidhi inoumba crystallites painotenderera 60 madhigirii, ayo anodzima zvinhu.Masayendisiti aida kuwana nzira yekudzivisa iyi crystallization;kana kuita kuti crystallization process iwedzere kudzoreka - kuitira kuti ukuru hwekristallite hwakaumbwa husazokanganisa chiedza.
Murabhoritari yePaderborn, masayendisiti akatanga asarudza mamorekuru epolylactic acid kuitira kuti achinje zvimiro zvezvinhu, kunyanya kunyungudika kwayo uye crystallization.Huber ane basa rekuongorora kuti zvinowedzerwa, kana simba remwaranzi, zvinogona kuvandudza zvimiro zvemidziyo."Takavaka diki-angle light scattering system zvakanyanya kuti izvi zvidzidze kuumbwa kwekristaro kana kunyunguduka maitiro, maitiro ane zvakakosha pakushanda kwemaziso," akadaro Huber.
Pamusoro peruzivo rwesainzi uye tekinoroji, chirongwa ichi chinogona kuunza zvakakosha zvehupfumi mushure mekuita.Chikwata chinotarisira kupa pepa rayo rekutanga mhinduro panopera 2022.
