I tēnei wā,ngā rauemi tākai whakapaipai pirau-koiorakua whakamahia mō te takai pakari o ngā kirīmi, ngā rīpene ngutu me ētahi atu mea whakapaipai. Nā te āhua motuhake o ngā mea whakapaipai, ehara i te mea me whai āhua ahurei anake, engari me whai takai hoki e tutuki ai āna mahi motuhake.
Hei tauira, ko te āhua kore pumau o ngā rauemi mata whakapaipai he rite ki te āhua o te kai. Nō reira, me whakarato ngā takai whakapaipai i ngā āhuatanga ārai whai hua ake, me te pupuri tonu i ngā āhuatanga whakapaipai. I tētahi taha, me wehe rawa te mārama me te hau, me karo i te waikura o te hua, me wehe hoki ngā huakita me ētahi atu moroiti kei uru ki te hua. I tētahi atu taha, me ārai hoki i te mimiti o ngā kai hohe o ngā whakapaipai e ngā rauemi takai, te tauhohe rānei ki a rātou i te wā e rongoa ana, ka pā ki te haumaru me te kounga o ngā whakapaipai.
Hei tāpiritanga, he nui ngā whakaritenga haumaru koiora mō ngā takai whakapaipai, nā te mea i roto i ngā tāpiringa o ngā takai whakapaipai, ka rewa pea ētahi matū kino e ngā whakapaipai, ā, ka poke ai ngā whakapaipai.
Ngā rauemi tākai whakapaipai pirau-koiora:
Rauemi PLAHe pai te tukatuka me te hototahi ki te koiora, ā, koinei te rauemi matua mō ngā takai whakapaipai pirau-koiora. He pakari te rauemi PLA me te ātete miihini, he mea pai mō ngā takai whakapaipai pakari.
Te Cellulose me ōna huaKo ngā polysaccharides ēnei e whakamahia whānuitia ana i roto i te hanga takai, ā, ko ngā polymer tūturu tino nui rawa atu o te ao. Kei roto ko ngā waeine monomer glucose e honoa ana mā roto i ngā here glycosidic B-1,4, e āhei ai ngā mekameka cellulose ki te hanga hononga hauwai kaha i waenga i ngā mekameka. He pai te takai cellulose mō te penapena i ngā whakapaipai maroke kore-waikawa.
Ngā rauemi māngaroHe polysaccharides i hangaia mai i te amylose me te amylopectin, i ahu mai i ngā witi, te manioka me ngā rīwai. Ko ngā rauemi māngaro e wātea ana i te hokohoko he ranunga māngaro me ētahi atu pūhui, pērā i te waipiro polyvinyl, te polycaprolactone rānei. Kua whakamahia ēnei rauemi thermoplastic e hangai ana ki te māngaro i roto i te whānuitanga o ngā tono ahumahi, ā, ka taea te whakatutuki i ngā tikanga o te tono extrusion, te werohanga werohanga, te pupuhi pupuhi, te pupuhi kiriata me te pahuka o ngā takai whakapaipai. He pai mō ngā takai whakapaipai maroke kore-waikawa.
KitosanHe pūmanawa tōna hei rauemi takai pirau-koiora mō ngā whakapaipai nā tōna kaha patu huakita. Ko te Chitosan he polysaccharide cationic i ahu mai i te deacetylation o te chitin, i ahu mai i ngā anga o ngā crustacean, i ngā hyphae harore rānei. Ka taea te whakamahi i te Chitosan hei paninga i runga i ngā kiriata PLA hei whakaputa takai ngāwari e pirau-koiora ana, ā, he antioxidant hoki.
