ʻO ka polylactic acid, i kapa ʻia ʻo polylactide, no ka ʻohana polyester.ʻO ka polylactic acid (PLA) he polymer polymerized me ka lactic acid ka mea nui.He nui nā mea maka a hiki ke hana hou.ʻO ke kaʻina hana o ka polylactic acid he pollution-free, a hiki i ka huahana ke biodegradable, e ʻike ana i ke kahe ʻana i ke ʻano, no laila he mea polymer ʻōmaʻomaʻo kūpono.ʻO ka polylactic acid (PLA) he ʻano hou o nā mea biodegradable.Hana ʻia ia mai nā mea starch i unuhi ʻia mai nā kumuwaiwai mea kanu hou (e like me ke kulina) ma o ka fermentation, a laila hoʻololi ʻia i polylactic acid ma o ka polymer synthesis.
He kūpono ka polylactic acid no ka hoʻoheheʻe ʻana, ka hoʻoheheʻe ʻana a me nā ʻano hana ʻē aʻe.He maʻalahi ke hana a hoʻohana nui ʻia.Hiki ke ho'ohana 'ia no ka ho'oponopono 'ana i nā pahu mea'ai like 'ole, nā mea'ai i ho'opa'a 'ia, nā pahu mea'ai wikiwiki, nā lole i ulana 'ole, nā lole 'oihana a me nā kīwila mai ka 'oihana i ka ho'ohana kīwila.A laila hiki ke hana ʻia i nā lole mahiʻai, nā lole mālama ola kino, nā ʻōpala, nā huahana maʻemaʻe, nā lole pale UV waho, nā lole lole, nā moena papahele, a me nā mea ʻē aʻe.Hiki ke ʻike ʻia he maikaʻi kona ʻano mīkini a me ke kino.
He aha nā mea maikaʻi o ka PLA maka?
1. He biodegradability maikaʻi kona.Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganism i ke ʻano ma lalo o nā kūlana kikoʻī, a hope loa e hoʻopuka i ke kalapona a me ka wai, me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni.ʻO ke ʻano o ka mālama ʻana i nā plastics maʻamau e hoʻomau ʻia a puhi ʻia, kahi e hoʻokuʻu ʻia ai ka nui o nā kinoea ʻōmaʻomaʻo i ka lewa, aʻo ka polylactic acid (PLA) plastics e kanu ʻia i loko o ka lepo no ka hoʻohaʻahaʻa ʻana, a komo pololei ka carbon dioxide i loko o ka lepo. ka lepo lepo a i ʻole e hoʻomoʻa ʻia e nā mea kanu, ʻaʻole e hoʻokuʻu ʻia i ka lewa a ʻaʻole e hana i kahi hopena ʻōmaʻomaʻo.
2. ʻO nā mea mechanical a me ke kino maikaʻi.He mea maʻalahi ke hana, hoʻohana nui ʻia, a loaʻa kahi manaʻo mākeke maikaʻi loa.
3. Hoʻopili maikaʻi a me ka degradability.Hoʻohana nui ʻia ia i ka lāʻau lapaʻau.
4. ʻO ka polylactic acid (PLA) ka mea like me ka petrochemical synthetic plastics i nā waiwai kino kumu a hiki ke hoʻohana nui ʻia no ka hana ʻana i nā huahana noi.ʻO ka Poly (lactic acid) (PLA) he maikaʻi ka luster a me ka ʻike, e like me ke kiʻi i hana ʻia me ka polystyrene a ʻaʻole hiki ke hāʻawi ʻia e nā huahana biodegradable ʻē aʻe.
5. ʻO ka polylactic acid (PLA) ka ikaika tensile maikaʻi loa a me ka ductility, a hiki ke hana ʻia e nā ʻano hana maʻamau.Hiki ke hana ʻia ka poly lactic acid (PLA) i nā huahana like ʻole e like me nā pono o nā ʻoihana like ʻole.
6. Poly (lactic acid) (PLA) film i maikai ea permeability, oxygen permeability a me carbon dioxide permeability, a me ia no hoi na hiʻohiʻona o ka ala kaawale.He mea maʻalahi ka hoʻopili ʻana i nā maʻi maʻi a me nā mold i ka ʻili o nā plastic biodegradable, no laila aia nā kānalua e pili ana i ka palekana a me ka maʻemaʻe.Eia nō naʻe, ʻo ka polylactic acid wale nō ka plastic biodegradable me nā waiwai antibacterial a anti mold maikaʻi loa.
7. Ke hoʻopau ʻia ka PLA, ua like kona waiwai wela me ko ka pepa, ʻo ia ka hapalua o ko nā plastik kahiko (e like me ka polyethylene).Eia kekahi, ʻaʻole ia e hoʻokuʻu i nā pūhui nitrogen, sulfide a me nā kinoea ʻona ʻē aʻe.
