Kūlana Kūʻai Kūʻai a me nā manaʻo o ka Biodegradable PLA Non woven Fabric

Ka nui makeke o ka waika polylactic

Polylactic acid (PLA), ma ke ʻano hemea hoʻoheheʻe ʻia i ke kaiapuni, ua hoʻohana nui ʻia i nā ʻano hana like ʻole e like me ka hoʻopili ʻana, textile, medical, a me ka mahiʻai i nā makahiki i hala iho nei, a ke hoʻomau nei ka nui o kāna mākeke. Wahi a ka loiloi a me nā helu helu o ka nui o ka mākeke polylactic acid, ʻo ka nui o ka mākeke polylactic acid (PLA) ka nui o ka honua e hiki i ka 11.895 biliona yuan (RMB) i ka makahiki 2022, a ke manaʻo ʻia nei e hōʻea i 33.523 biliona yuan e 2028. ʻO ka nui o ka ulu ʻana o ka hui makahiki o ka polylactic acid (PLA) mākeke i ka wā wānana.

Mai ka hiʻohiʻona o nā kahua noi o ka polylactic acid, ʻo nā mea hoʻopihapiha i kēia manawa ka nui o nā mea kūʻai aku, ʻoi aku ma mua o 65% o ka nui o ka ʻai. Me ka hoʻomaikaʻi ʻana o ka ʻike kaiapuni a me nā koi o ka hoʻomohala hoʻomau, e manaʻo ʻia ka hoʻohana ʻana o ka polylactic acid i loko o ke kahua paʻi. Ma ka manawa like, ua hoʻolako pū nā kahua noi o nā mea ʻai meaʻai, fiber / non-woven fabrics, 3D paʻi mea, etc. Mai ka hiʻohiʻona o ka koi maoli, me ke kākoʻo ʻana i ka paʻa ʻana i ka plastic a me nā hoʻoponopono pāpā ʻana e nā aupuni ma nā ʻāina like ʻole a me nā ʻāina, ke hoʻomau nei ka ulu ʻana o ka noi honua no nā plastic biodegradable. ʻO ka noi no ka polylactic acid ma ka mākeke o Kina i ka makahiki 2022 e manaʻo ʻia e hōʻea i 400000 tons, a ua manaʻo ʻia e hōʻea i 2.08 miliona tons e 2025. I kēia manawa, ʻo ka wahi hoʻohana nui o ka polylactic acid he mau mea hoʻopihapiha, ʻoi aku ma mua o 65% o ka nui o ka ʻai; ʻO nā mea aʻe e like me nā mea ʻai, nā lole fiber/non-woven, a me nā mea paʻi 3D. ʻO ʻEulopa a me ʻAmelika ʻAmelika ka mākeke nui loa no PLA, aʻo ka ʻāina ʻo Asia Pacific kekahi o nā mākeke wikiwiki loa.

Wahi kūʻai o ka waika polylactic

ʻO ka hoʻonui ʻana i ka ʻike kaiapuni e hāpai i ka ulu ʻana o ka mākeke: Me ka hoʻonui ʻana i ka ʻike kaiapuni honua, ke hoʻomau nei ka noi no nā mea biodegradable. ʻO ka polylactic acid, ma ke ʻano he mea i loaʻa mai nā kumuwaiwai hou a me ka biodegradable i loko o ke kaiapuni kūlohelohe, ua makemake nui ʻia e nā ʻoihana a me nā mea kūʻai aku.

ʻO ka hiki ke hoʻomohala o ka hoʻololi ʻana i nā plastics kuʻuna: ʻO ka polylactic acid he biodegradability maikaʻi a me ka biocompatibility, a hiki ke hoʻohana ʻia e hoʻololi i nā huahana plastic disposable e like me nā ʻeke plastik, nā papa ʻaina, nā mea hoʻopihapiha, a me nā mea ʻē aʻe.

Ke hoʻomau nei ka hoʻomaikaʻi ʻana i nā waiwai waiwai: Me ka holomua o ka ʻenehana, ua hoʻomaikaʻi mau ʻia ka hana o ka polylactic acid, ʻoi aku ka nui o ka ikaika, ka pale ʻana i ka wela, a me ka hiki ke hana, e holomua nui ana a hoʻonui i kāna mau noi, e like me ka paʻi 3D, nā mea lapaʻau, a me nā kula ʻē aʻe.

Kākoʻo kulekele a me ka hoʻomohala ʻana i nā kaulahao ʻoihana: ʻO kekahi mau ʻāina a me nā ʻāina e paipai i ka hoʻohana ʻana i nā mea biodegradable ma o ke kākoʻo kulekele a me nā hana kānāwai, e hāpai i ka ulu ʻana o ka mākeke polylactic acid. Eia nō naʻe, me ka hoʻomau mau ʻana o ke kaulahao ʻoihana a me ka hōʻemi hou ʻana i ke kumukūʻai, e lilo ka mākeke polylactic acid i mea hoʻokūkū.

Ke ʻimi nei i nā wahi noi e puka mai ana: ʻAʻole wale ka mākeke o ka polylactic acid i loko o ka ʻeke kuʻuna a me nā mea e pono ai i kēlā me kēia lā, akā loaʻa pū kekahi i nā manaʻo noi no ka hoʻololi ʻana i ka lepo, nā lako lapaʻau, nā textiles, a me nā māla ʻē aʻe. I ka wā e hiki mai ana, ʻo ka ʻimi ʻana i nā māla e kū mai ana e hoʻoulu hou i ka makemake o ka mākeke.

Ma ke ʻano holoʻokoʻa, ma ke ʻano he biodegradable, polylactic acid ka maikaʻi o ka hoʻomohala ʻana i ka mākeke, ʻoi aku ka maikaʻi me ka hoʻolaha ʻana o ka ʻike kaiapuni, hoʻomaikaʻi ʻenehana, a me ke kākoʻo kulekele. Manaʻo ka mākeke polylactic acid e hoʻolauna i nā manawa hoʻomohala hou aʻe.

ʻO nā ʻoihana koʻikoʻi i ka ʻoihana lole lole ʻole o ka PLA

ʻO nā ʻoihana nui i ka honua biodegradableʻoihana lole lole ʻole PLA, me Asahi Kasei Hui, Qingdao Vinner Mea Hou, Foshan Membrane Technology, Great Lakes Filters, eSUN Bio Material, WINIW Nonwoven Materials, Foshan Guide Textile, D-TEX Nonwovens, Fujian Greenjoy Biomaterial, Techtex, TotalEnergies Corbion, National Bridge Industrial.

Nā Luʻi i alo ʻia e ka PLA Nonwovens Industry

ʻOiai ka manaʻo o ka ulu ʻana, ke kū nei ka ʻoihana nonwovens PLA i kekahi mau pilikia. ʻO kekahi pilikia nui ke kumukūʻai o ka hana. ʻOi aku ke kumukūʻai o ka PLA i kēia manawa ke hoʻohālikelike ʻia me nā mea hana ʻole i ulana ʻia. Eia nō naʻe, manaʻo ʻia ka holomua o ka ʻenehana a me ka ʻoihana waiwai e hoʻohaʻahaʻa i nā kumukūʻai hana i ka wā e hiki mai ana. ʻO kekahi pilikia ʻo ka loaʻa ʻana o nā mea maka. Loaʻa ʻia ka PLA mai nā kumuwaiwai hou, a hiki i nā loli i ke kaulahao hoʻolako ke hopena i ka ulu ʻana o ka ʻoihana.

Ka hopena o ka PLA Nonwovens

Ka hopena kaiapuni o PLA nonwovens (PLA lole i ulana ole ia) he mea koʻikoʻi e noʻonoʻo ai. Loaʻa ʻia ka PLA mai nā kumuwaiwai hou a loaʻa iā ia kahi kapuaʻi kalapona haʻahaʻa i hoʻohālikelike ʻia me nā mea i hoʻokumu ʻia i ka petroleum. ʻO nā PLA nonwovens hiki ke hoʻopuehu ʻia a wāwahi i nā ʻāpana kūlohelohe ma lalo o nā kūlana kikoʻī. Hoʻemi kēia hiʻohiʻona i ka hōʻiliʻili ʻana o nā ʻōpala non-biodegradable i loko o nā pae ʻāina a kōkua i ka wā e hiki mai ana. Eia nō naʻe, he mea nui e hōʻoia i ka hoʻonohonoho pono ʻana o nā ʻōnaehana hoʻokele ʻōpala e hoʻonui i nā pono o nā PLA nonwovens.

Dongguan Liansheng Non ulana 'enehana Co., Ltd.ua hoʻokumu ʻia ma Mei 2020. He ʻoihana hana lole lole ʻaʻole i ulana nui ʻia e hoʻohui i ka noiʻi a me ka hoʻomohala ʻana, ka hana ʻana, a me ke kūʻai aku. Hiki iā ia ke hana i nā kala like ʻole o ka PP spunbond non-woven fabrics me ka laulā o lalo o 3.2 mika mai 9 grams a 300 grams.
