Ka pirau te PLA?
•Kua roa te waikawa polylactic, e mōhiotia ana ko te PLA, e whakamahia ana. Heoi, nō nā tata nei ngā kaihanga nui o te PLA i uru mai ki te mākete whai muri i te whiwhinga pūtea mai i ngā kamupene nunui e hiahia ana ki te whakakapi i ngā kirihou hangai. Nō reira, ka pirau te PLA?
•Ahakoa ehara i te mea ngāwari te whakautu, i whakatau mātou ki te whakamārama me te taunaki atu kia pānuihia atu ki te hunga e hiahia ana. Kāore te PLA e pirau-koiora, engari he pirau. Kāore i te kitea ngā whākōkī ka taea te wawahi i te PLA i roto i te taiao. Ko te Proteinase K he whākōkī e whakaoho ana i te pirau o te PLA mā te waikura. I tūhuratia e ngā kairangahau pērā i a Williams i te tau 1981 me Tsuji rāua ko Miyauchi i te tau 2001 te take mēnā he pirau-koiora te PLA. Kei roto i te pukapuka Biomaterials Science: An Introduction to Medical Materials ā rātou hua, ā, i whakaaturia ki tētahi hui a te European Biomaterials Society. E ai ki ēnei puna, ko te waikura te mea matua e whakahaeretia ana e te PLA, motuhake mai i tētahi kaihoko koiora. Ahakoa he tokomaha te hunga e whakaaro ana he pirau-koiora te PLA, he mea nui kia mōhio ki tēnei.
•Ina hoki, he tino onge te waikura o te PLA mā te proteinase K, ā, kāore e nui te hiranga o tēnei mea hei kōrero anō i roto i te pūtaiao rauemi koiora. Ko te tumanako ka whakamāramahia e tēnei ngā take e pā ana ki te pirau o te PLA, ā, ka haere tonu ā mātou mahi ki te whakarato i ngā otinga pai rawa atu mō ō hiahia kirihou e pai ana ki te taiao, e pirau ana hoki.
Iwhakatau:
He kirihou pirau te PLA e whakamahia whānuitia ana i roto i ngā taonga o ia rā pēnei i ngā putea me ngā kapu whakakorekore. Heoi, ka pirau noa i roto i ngā taiao whakamomona ahumahi, i ngā taiao nakunaku anaerobic rānei, ā, he uaua te pirau i roto i ngā taiao taiao noa. Kua whakaūhia e ngā rangahau he iti noa te pirau o te PLA i roto i te taiao moana.
