I te pikinga ake o te mōhiotanga ki te taiao, kei te piki haere hoki te hiahia o te tangata mō ngā rauemi e pai ana ki te taiao me ā rātou hua. Kei te whakamahia haeretia ngā putea tākai PLA me ngā putea tākai PLA hei whakawairakau i te mākete.
Ko te waikawa polylactic, e mōhiotia ana ko te PLA (Polylactic Acid), he pūmua i whiwhihia mā te whakakotahi i te waikawa lactic hei rauemi matua. Ko te pūtake o ngā rauemi mata he nui mai i te kānga, te manioka, me ētahi atu. Kāore he parahanga i roto i te tukanga whakaputa PLA, ā, ka taea te pirau me te hangarua i te hua i roto i te taiao.
Ngā Painga o te PLA
1. Te pirau: I muri i te maka atu i te PLA, ka taea te pirau katoa hei wai me te hauhā waro i raro i ngā āhuatanga motuhake, ka hoki anō ki te tohanga taiao, ka karo i te parahanga roa ki te taiao i puta mai i ngā kirihou tuku iho.
2. Ngā rauemi whakahou: Ko te nuinga o te PLA ka whakapūhuitia mai i te waikawa lactic i tangohia mai i te māngaro kānga, te tō me ētahi atu hua, he rauemi whakahou, ā, ka whakaiti i te whakawhirinaki ki ngā rauemi hinu.
3. He pai te uruhanga o te hau, te uruhanga hāora me te uruhanga waro-hauhā, ā, he āhuatanga anō hoki tōna ki te wehe i te haunga. Ka piri ngā huaketo me ngā pokepokea ai ki te mata o ngā kirihou pirau-ora, nō reira kei reira ngā āwangawanga mō te haumaru me te akuaku. Heoi, ko te PLA anake te kirihou pirau-ora he pai rawa ngā āhuatanga ārai-huakita me te ārai-pokepokea.
Te tikanga whakapōrearea o te PLA
1. Te Whakapūngao Wai: Ka pakaru te rōpū ester o te mekameka matua, ka whakaitihia te taumaha ngota.
2. Te pirau wera: he āhuatanga uaua e hua ake ai ngā pūhui rerekē, pērā i ngā ngota māmā ake me ngā oligomer rārangi me te huringa me ngā taumaha ngota rerekē, tae atu ki te lactide.
3. Te pirau whakaahua: Ka taea e te hihi ultraviolet te pirau. He take nui tēnei mō te pānga o te PLA ki te hihi o te rā i roto i ngā kirihou, ngā ipu tākai, me ngā tono kiriata.
Te whakamahinga o te PLA i roto i te mara tākai
He whānuitia ngā momo rauemi PLA e whakamahia ana. I roto i te umanga takai, ko te kiriata PLA te nuinga o te wā e whakamahia ana i roto i ngā takai o waho o te kai, te inu me te rongoā hei whakakapi i ngā takai kirihou tuku iho, kia tutuki ai te kaupapa o te tiaki taiao me te pumau.
