He aha ka PLA? ʻO ka PLA kahi mea biodegradable hou, i hana ʻia me ka starch maka i manaʻo ʻia e nā kumuwaiwai mea kanu hou (e like me ke kulina). Hana ʻia nā mea maka starch i ʻakika lactic ma o ka fermentation a laila hoʻololi ʻia i polylactic acid ma o ka synthesis kemika.
Loaʻa i ka PLA ka biodegradability kūʻokoʻa, biocompatibility a ʻaʻole e waiho i nā pilikia kūlohelohe ma hope o ka hoʻohaʻahaʻa ʻana. E lilo ia i mea mālama kaiaola a me ke kaiapuni me ka noi ākea a me nā manaʻo hoʻomohala i ka wā e hiki mai ana. Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganisms i ke ʻano, a hoʻopuka hope loa i ka carbon dioxide a me ka wai me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni, he mea maikaʻi loa ia i ka mālama ʻana i ke kaiapuni. ʻIke ʻia ʻo ia he mea pili i ke kaiapuni. He nui nā noi a PLA, e like me ka extrusion, injection molding, kiʻi kiʻiʻoniʻoni, wili a pēlā aku. Ka helu onā mīkini e hana ana i nā plastic PLAke mahuahua nei no hoi.
PLA=Mai mea kanu a i ka lepo, he koho poepoe maoli
E like meHEY12 Hiki ke hoopau iaMīkini hana kīʻaha PLA, loaʻa i nā kīʻaha PLA biodegradable a me nā kīʻaha.
HEY01 Mea Hoʻolele PaʻaMea ʻai Biodegradable a me ka mīkini hana pahu,ka mea nui no ka hana ʻana i nā ipu plastik like ʻole (pahu hua, ipu huaʻai, pahu meaʻai, pahu pahu, a me nā mea ʻē aʻe) me nā lau thermoplastic.
GTMSMART Loaʻa iā ia nā lako ʻoihana a loaʻa ka mahalo lokahi mai nā mea kūʻai aku ma nā ʻāina like ʻole. Inā makemake ʻoe e ʻike hou aku e pili ana i nā mīkini huahana PLA like ʻole, e ʻoluʻolu e kūkākūkā!
