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 takai pirau-koiora matua mō ngā mea whakapaipai. 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.
