Kei te rangahau ngā kaipūtaiao o Tiamana me Hōrana i ngā rongoā hou e pai ana mō te taiaoPLAngā rauemi. Ko te whāinga he whakawhanake i ngā rauemi pumau mō ngā tono whatu pēnei i ngā rama motuka, ngā karāhe arotahi, ngā kirihou whakaata, ngā aratohu rama rānei. I tēnei wā, ko te nuinga o ēnei hua he mea hanga ki te polycarbonate, ki te PMMA rānei.
E hiahia ana ngā kaipūtaiao ki te kimi i tētahi kirihou e ahu mai ana i te koiora hei hanga rama waka. E kitea ana ko te waikawa polylactic te rauemi e tika ana.
Mā tēnei tikanga, kua whakatauhia e ngā kaipūtaiao ētahi raruraru e pā ana ki ngā kirihou tuku iho: tuatahi, mā te tahuri ki ngā rauemi whakahou ka taea te whakaiti i te pēhanga i puta mai i te hinu mata ki te umanga kirihou; tuarua, ka taea te whakaiti i ngā tukunga hauhā waro; tuatoru, kei roto i tēnei te whakaaro ki te huringa ora katoa o te rauemi.
"Ehara i te mea he painga noa iho o te waikawa polylactic mō te pumau, engari he tino pai hoki ōna āhuatanga whatu, ā, ka taea te whakamahi i roto i te whānuitanga kitea o ngā ngaru hikohiko," te kī a Tākuta Klaus Huber, he ahorangi i Te Whare Wānanga o Paderborn i Tiamana.
I tēnei wā, ko tētahi o ngā uauatanga e wikitoriahia ana e ngā kaipūtaiao ko te whakamahinga o te waikawa polylactic i roto i ngā mara e pā ana ki te LED. E mōhiotia ana te LED he puna mārama whai hua, he pai hoki mō te taiao. "Ina koa, ko te roa o te ora mahi me te hihi e kitea ana, pērā i te mārama kikorangi o ngā rama LED, e tino hiahiatia ana ngā rauemi whatu," te whakamārama a Huber. Koinei te take me whakamahi ngā rauemi tino pakari. Ko te raruraru: Ka ngohengohe te PLA i te 60 nekehanga pea. Heoi, ka taea e ngā rama LED te eke ki te pāmahana tae atu ki te 80 nekehanga i te wā e whakahaerehia ana.
Ko tētahi atu uauatanga wero ko te whakatioatatanga o te waikawa polylactic. Ka hangaia e te waikawa polylactic ngā tioata i te pāmahana tata ki te 60 nekehanga, ka whakapōuri i te rauemi. I hiahia ngā kaipūtaiao ki te kimi huarahi hei karo i tēnei whakatioatatanga; ki te whakahaere rānei i te tukanga whakatioatatanga — kia kore ai te rahi o ngā tioata i hangaia e pā ki te mārama.
I roto i te taiwhanga o Paderborn, i tuatahitia e ngā kaipūtaiao ngā āhuatanga ngota o te waikawa polylactic hei whakarerekē i ngā āhuatanga o te rauemi, inā koa tōna āhua rewa me te tioata. Ko Huber te kawenga mō te rangahau i te nui o te kaha o ngā tāpiringa, te pūngao irahiko rānei, ki te whakapai ake i ngā āhuatanga o ngā rauemi. "I hangaia e mātou he pūnaha marara mārama koki-iti mō tēnei hei ako i ngā tukanga hanganga tioata, rewa rānei, arā, ngā tukanga he pānga nui ki te mahi whatu," te kī a Huber.
Haunga te mātauranga pūtaiao me te hangarau, tera pea ka puta he hua ōhanga nui i muri i te whakatinanatanga o te kaupapa. E matapaetia ana e te tīma ka tukuna atu tā rātou pepa whakautu tuatahi i te mutunga o te tau 2022.
