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 na kahua lapaau a me ke ola kino.
