ʻO ka polylactic acid (H-[OCHCH3CO]n-OH) maikaʻi ke kūpaʻa wela, ʻo ka mahana hana ʻo 170 ~ 230 ℃, a he kūpaʻa maikaʻi kona.Hiki ke hana ʻia ma nā ʻano like ʻole, e like me ka extrusion, spinning, biaxial stretching, Injection blow molding.Ma waho aʻe o ka biodegradable, nā huahana i hana ʻia me ka polylactic acid he biocompatibility maikaʻi, gloss, transparency, manaʻo lima a me ka pale wela.ʻO ka polylactic acid (PLA) i hoʻomohala ʻia e Guanghua Weiye kekahi mau mea antibacterial a me ka lapalapa ahi.A me ka pale ʻana o UV, no laila he nui ka hoʻohana ʻana.Hiki ke hoʻohanaʻia e like me nā mea hoʻopili, nā fibers a me nā mea i ulanaʻoleʻia, a me nā mea'ē aʻe.
ʻO nā pono nui o ka polylactic acid penei:
ʻO ka polylactic acid (PLA) kahi ʻano mea biodegradable hou, i hana ʻia mai ka starch maka i manaʻo ʻia e nā kumu mea kanu hou (e like me ke kulina).Hoʻomaʻamaʻa ʻia nā mea maka starch no ka loaʻa ʻana o ka glucose, a laila fermented me ka glucose a me kekahi mau kānana e hana ai i ka waika lactic maʻemaʻe kiʻekiʻe, a laila hoʻohui ʻia kekahi waika polylactic kaumaha mole e ka synthesis kemika.Loaʻa iā ia ka biodegradability maikaʻi.Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganisms i ke ʻano, a i ka hopena e hana ʻia ke kalapona a me ka wai me ka ʻole o ka hoʻohaumia ʻana i ke kaiapuni.He mea maikaʻi loa kēia i ka mālama ʻana i ke kaiapuni a ua ʻike ʻia ʻo ia he mea pili i ke kaiapuni.Hoʻohana mau ʻia nā plastik maʻamau e ka ʻā ʻana a me ka puhi ʻana, e hoʻokuʻu ʻia ka nui o nā kinoea hoʻomaʻemaʻe i ka lewa, aʻo ka polylactic acid plastics e kanu ʻia i loko o ka lepo e hoʻohaʻahaʻa, a komo pololei ke kalapona i hana ʻia i loko o ka lepo. e nā mea kanu, ʻaʻole e hoʻokuʻu ʻia i ka lewa.ʻAʻole e hoʻoulu i ka hopena greenhouse.
