ʻO ka polylactic acid (PLA) kahi mea bio-based a hoʻololi hou ʻia, i hana ʻia mai nā mea starch i manaʻo ʻia e nā mea kanu mea kanu hou (e like me ka maile a me ka cassava).Hoʻopili ʻia nā mea maka o ka starch no ka loaʻa ʻana o ka glucose, a laila hana ʻia ka waika lactic maʻemaʻe kiʻekiʻe e ka fermentation o ka glucose a me kekahi mau ʻano, a laila hoʻohui ʻia ka waika POlylactic me kahi kaumaha molekala e ka synthesis kemika.Loaʻa iā ia ka biodegradability maikaʻi.Ma hope o ka hoʻohana ʻana, hiki ke hoʻohaʻahaʻa ʻia e nā microorganism i ke ʻano ma lalo o nā kūlana kikoʻī, a i ka hopena e hoʻopuka i ka carbon dioxide a me ka wai.ʻAʻole ia e hoʻohaumia i ke kaiapuni, he mea maikaʻi loa ia i ka pale ʻana i ke kaiapuni a ʻike ʻia ʻo ia he mea pili i ke kaiapuni.Kina PP Nonwoven lole lole
PLA,like pū me kekahi ʻanoPET spunbond,He maikaʻi ka drapability, smoothness, moisture absorption a me ka ea permeability, kūlohelohe bacteriostasis a me ka ʻili e hōʻoluʻolu ana i ka waika nāwaliwali, maikaʻi ka wela a me ka pale UV.
PLA i kākau ʻia e like me: polylactic acid
ʻO ka polylactic acid, i kapa ʻia ʻo polylactide, no ka ʻohana polyester.ʻO ka polylactic acid (PLA) kahi polymer i loaʻa ma ka polymerization o ka lactic acid ma ke ʻano he kumu kumu.Ua lawa ke kumu waiwai maka a hiki ke hana hou.Hoʻohana nui ia i ke kulina a me ka cassava ma ke ʻano he kumu.ʻO ke kaʻina hana o ka PLA he pollution-free, a hiki ke biodegraded ka huahana e ʻike i ka pōʻaiapuni i ke ʻano, no laila he mea polymer ʻōmaʻomaʻo kūpono.
ʻO ka polylactic acid ka paʻa wela maikaʻi, ka mahana wela 170 ~ 230 ℃, ka pale ʻana o ka solvent maikaʻi, hiki ke hana ʻia i nā ʻano like ʻole, e like me ka extrusion, spinning, biaxial stretching, injection blow molding.ʻO nā huahana i hana ʻia me ka polylactic acid ʻaʻole hiki ke biodegradable, akā loaʻa pū kekahi biocompatibility maikaʻi, gloss, transparency, feel and heat resistance.Loaʻa iā lākou kekahi mau bacterial resistance, flame retardant a me UV resistance, no laila ua hoʻohana nui ʻia lākou e like me nā mea hoʻopihapiha, nā fibers a me nā nonwovens, a me nā mea ʻē aʻe. , hana pepa) a me nā kahua lapaʻau a me ke olakino.
