He aha te Polylactic Acid PLA CAS 26100-51-6?

Ko te poly (waikawa lactic), e mohiotia ana ano ko te polylactide, he momo hou o nga mea koiora ka riro mai i te polymerization o te waikawa lactic hei rauemi mata matua. He pai te koiora, ka taea te whakaheke katoa e nga microorganism i roto i te taiao i muri i te whakamahinga, i te mutunga ka whakaputa te waro hauhaa me te wai kaore e pokea te taiao. He tino painga tenei mo te whakamarumaru i te taiao, a, ka mohiotia hei taonga taiao. He maha nga tono a te PLA, tae atu ki te tangohanga, te werohanga mo te werohanga, te kume kiriata, te hurihuri, me etahi atu mara.

Taupānga

Ko te waikawa polylactic(PLA) i whakauruhia i te tau 1966 mo nga whakaurunga pokanga whakakino. Ka puta te waikawa lactic, he takawaenga noa o te kawa warowaihā. Ko nga tui o te waikawa polyglycolic he reiti whakahekenga e rite ana ki te raupapa whakaora o nga kopa taiao. He maha nga tono a te PLA, tae atu ki te tangohanga, te werohanga, te tarai kiriata, te hurihuri, me etahi atu mara.
