I tēnei wā, ko te wāhanga matua o te whakamahi i te waikawa polylactic ko ngā rauemi tākai, neke atu i te 65% o te whakamahinga katoa; ā, muri iho ko ngā tono pēnei i ngā taputapu kai, ngā muka/kakahu kore-whatu, me ngā rauemi tā 3D. Ko Ūropi me Amerika Te Raki ngā mākete nui rawa atu mō te PLA, ko Āhia Moana-nui-a-Kiwa tētahi o ngā mākete tino tere te tipu o te ao i te mea kei te tipu haere tonu te tono mō te PLA i ngā whenua pēnei i a Haina, Hapani, Kōrea ki te Tonga, Īnia me Thailand.
Mai i te tirohanga o te momo tono, nā te pai o ōna āhuatanga miihini me te ā-tinana, he pai te waikawa polylactic mō te hanga whakarewa, te hanga werohanga, te hanga pupuhi whakarewa, te miro, te pahuka me ētahi atu tukanga tukatuka kirihou nui, ā, ka taea te hanga hei kiriata me te pepa, muka, waea, paura me ētahi atu momo. Nō reira, i te roanga o te wā, kei te whānui haere tonu ngā āhuatanga tono o te waikawa polylactic i te ao, ā, kua whānuitia te whakamahinga i roto i ngā takai me ngā taputapu kai, ngā hua takai putea kiriata, te keri hau shale, ngā muka, ngā papanga, ngā rauemi tā 3D me ētahi atu hua. Kei te tūhuratia tonutia tōna pūmanawa tono i roto i ngā mara o te rongoā, ngā wāhanga motuka, te ahuwhenua, te ngahere me te tiaki taiao.
I roto i te whakamahinga o te ao motuka, i tēnei wā, ka tāpirihia ētahi atu rauemi polymer ki te PLA hei hanga i ngā hiato hei whakapai ake i te ātete wera, te ngāwari me te ātete pānga o te PLA, ā, ka whānui ake te whānuitanga o tana whakamahinga i roto i te mākete motuka.
Te tūnga o ngā tono ki tāwāhi
I tīmata wawe te whakamahinga o te waikawa polylactic i roto i ngā motuka ki tāwāhi, ā, kua tino pakari te hangarau, ā, kua tino matatau te whakamahinga o te waikawa polylactic whakarerekētia. Ko ētahi waitohu motuka o tāwāhi e mōhiotia ana e tātou e whakamahi ana i te waikawa polylactic whakarerekētia.
I te mahi tahi a Mazda Motor Corporation me Teijin Corporation me Teijin Fiber Corporation, kua whakawhanakehia e rātou te papanga koiora tuatahi o te ao i hangaia ki te 100% waikawa polylactic, e whakamahia ana mō ngā whakaritenga kounga me te pakari o te taupoki nohoanga motuka i roto i te roto o te motuka. waenganui; I hangaia, i hokona hoki e te Kamupene Mitsubishi Nylon o Hapani tētahi momo PLA hei rauemi matua mō ngā whāriki papa motuka. I whakamahia tēnei hua i roto i te motuka ranu hou o te tuatoru o ngā whakatipuranga a Toyota i te tau 2009.
Ko te rauemi muka waikawa polylactic e pai ana ki te taiao i hangaia e Toray Industries Co., Ltd. o Hapani, i whakamahia hei uhi tinana me te papa o roto o te sedan ranu HS 250 h a Toyota Motor Corporation. Ka taea hoki te whakamahi i tēnei rauemi mō ngā tuanui o roto me ngā whakapaipai tatau, me ngā rauemi whakapaipai.
Ko te tauira Toyota Raum o Hapani e whakamahi ana i te muka kenaf/pūhui PLA hei hanga uhi potae tāpui, me te rauemi polypropylene (PP)/PLA kua whakarerekētia hei hanga panera tatau motuka me ngā panera whakapaipai taha.
Kua whakawhanakehia ngātahitia e te Kamupene Röchling Tiamana me te Kamupene Corbion tētahi rauemi hiato o te PLA me te muka karāhe, te muka rakau rānei, e whakamahia ana i roto i ngā wāhanga o roto o ngā motuka me ngā wāhanga mahi.
Kua whakawhanakehia e te Kamupene RTP o Amerika ngā hua hiato muka karāhe, e whakamahia ana i roto i ngā hipoki hau motuka, ngā ārai rā, ngā parepare āwhina, ngā pare taha me ētahi atu wāhanga. Ko ngā hipoki hau EU, ngā taupoki rā, ngā pare-iti, ngā pare taha me ētahi atu wāhanga.
Kua whakawhanakehia e te kaupapa EU ECOplast tētahi kirihou koiora i hangaia mai i te PLA me te nanoclay, e whakamahia motuhaketia ana mō te hanga wāhanga motuka.
Tūnga tono ā-rohe
Kua roa te rangahau mō te whakamahinga o te PLA ā-rohe i roto i te umanga motuka, engari nā te pai haere o te mōhiotanga ki te tiaki taiao ā-rohe, kua tīmata ngā kamupene motuka me ngā kairangahau ā-rohe ki te whakanui ake i te rangahau me te whanaketanga me te whakamahinga o te PLA kua whakarerekētia mō ngā waka, ā, kua tere te whanaketanga me te whakatairanga o te whakamahinga o te PLA i roto i ngā motuka. I tēnei wā, ko te PLA ā-rohe te nuinga e whakamahia ana i roto i ngā wāhanga me ngā wāhanga o roto o ngā motuka.
Kua whakarewahia e Lvcheng Biomaterials Technology Co., Ltd. ngā rauemi hiato PLA kaha-teitei, ā, kua whakamahia nei ki roto i ngā whakarara hau o ngā motuka, ngā anga matapihi tapatoru me ētahi atu wāhanga.
Kua angitu a Kumho Sunli i te whakawhanake i te PC/PLA polycarbonate, he pai ngā āhuatanga miihini, he pirau-ora, he hangarua hoki, ā, e whakamahia ana i roto i ngā wāhanga o roto o ngā motuka.
Kua whakawhanakehia ngātahitia hoki e Te Whare Wānanga o Tongji me SAIC ngā rauemi hiato waikawa polylactic/muka taiao, ka whakamahia hei rauemi mō roto i ngā waka waitohu a SAIC.
Ka whakanuia ake ngā rangahau ā-rohe mō te whakarerekētanga o te PLA, ā, ko te arotahi ā muri ake nei ka aro ki te whakawhanake i ngā matū waikawa polylactic me te roa o te mahi me te mahi e tutuki ai ngā whakaritenga o te whakamahinga. I te whanaketanga me te ahunga whakamua o te hangarau whakarerekētanga, ka whānui ake te whakamahinga o te PLA ā-rohe i roto i te mara o ngā motuka.
