Masayendisiti anobva kuGermany neNetherlands ari kutsvaga mishonga mitsva isingakuvadzi zvakatipoteredzaPLAzvinhu. Chinangwa ndechekugadzira zvinhu zvinogara kwenguva refu zvekushandisa maziso zvakaita semwenje yemotokari, malenzi, mapurasitiki anodzora chiedza kana nhungamiro dzemwenje. Parizvino, zvigadzirwa izvi zvinowanzogadzirwa nepolycarbonate kana PMMA.
Masayendisiti ari kuda kuwana purasitiki yakagadzirwa nemakemikari kuti igadzire marambi emotokari. Zvakazoonekwa kuti polylactic acid imhando yakakodzera.
Kuburikidza nenzira iyi, masayendisiti akagadzirisa matambudziko akati wandei anosangana nemapurasitiki echinyakare: chekutanga, kutendeukira kuzvinhu zvinogona kushandiswazve kunogona kuderedza zvinobudirira kumanikidzwa kunokonzerwa nemafuta asina kucheneswa muindasitiri yepurasitiki; chechipiri, kunogona kuderedza kuburitswa kwecarbon dioxide; chechitatu, izvi zvinosanganisira kufunga nezvehupenyu hwese hwezvinhu.
"Polylactic acid haina zvayakanakira chete panyaya yekuchengetedza zvinhu, inewo hunhu hwakanaka hwekuona uye inogona kushandiswa mumafungu emagetsi anooneka," anodaro Dr. Klaus Huber, purofesa paYunivhesiti yePaderborn muGermany.
Parizvino, chimwe chezvinetso zviri kukundwa nesainzi kushandiswa kwepolylactic acid muminda ine chekuita neLED. LED inozivikanwa senzvimbo yechiedza inoshanda uye isingakuvadzi nharaunda. "Zvikurukuru, hupenyu hurefu hwebasa uye mwaranzi inoonekwa, senge mwenje webhuruu wemwenje yeLED, inoda zvakanyanya zvinhu zve optical," anotsanangura Huber. Ichi ndicho chikonzero nei zvinhu zvakasimba zvakanyanya zvichifanira kushandiswa. Dambudziko nderekuti: PLA inonyorova paanenge madhigirii makumi matanhatu. Zvisinei, mwenje ye LED inogona kusvika tembiricha yakakwira kusvika madhigirii makumi masere panguva yekushanda.
Chimwe chinonetsa ndechekuita kuti polylactic acid iite crystallization. Polylactic acid inogadzira makristaro paanenge madhigirii makumi matanhatu, izvo zvinoita kuti zvinhu zvisanyatsooneka. Masayendisiti aida kutsvaga nzira yekudzivirira kuumbwa uku; kana kuti kuita kuti maitiro ekugadzira makristaro ave nyore kudzora - kuitira kuti saizi yemakristaro akaumbwa isakanganise chiedza.
Murabhoritari yePaderborn, masayendisiti akatanga aona hunhu hwemamorekuru epolylactic acid kuitira kuti achinje hunhu hwechinhu chacho, kunyanya mamiriro acho ekunyunguduka uye kugadzika kwekristaro. Huber ine basa rekuongorora kuti zvinowedzera, kana simba remwaranzi, zvinogona sei kuvandudza hunhu hwezvinhu. "Takavaka sisitimu yekupararira kwechiedza chekona diki kuitira kuti izvi zvidzidze maitiro ekuumbwa kwekristaro kana kunyunguduka, maitiro ane simba guru pakushanda kwemaziso," akadaro Huber.
Kuwedzera paruzivo rwesainzi nehunyanzvi, chirongwa ichi chinogona kuunza mabhenefiti makuru ehupfumi mushure mekuitwa kwacho. Chikwata ichi chinotarisira kupa bepa rayo rekutanga remhinduro panosvika kupera kwa2022.
