Msika Wamsika ndi Zomwe Zikuyembekezeka za Biodegradable PLA Zosalukidwa

Kukula kwa msika wa polylactic acid

Polylactic acid (PLA), mongazinthu zachilengedwe zowola ndi zachilengedwe, yakhala ikugwiritsidwa ntchito kwambiri m’madera osiyanasiyana monga kulongedza katundu, nsalu, zamankhwala, ndi ulimi m’zaka zaposachedwapa, ndipo kukula kwake kwa msika kukukulirakulirabe. Malinga ndi kusanthula ndi ziwerengero za kukula kwa msika wa polylactic acid, msika wapadziko lonse wa polylactic acid (PLA) ufika pa 11.895 biliyoni ya yuan (RMB) mu 2022, ndipo ukuyembekezeka kufika 33.523 biliyoni pofika 2028.

Malinga ndi momwe minda yogwiritsira ntchito polylactic acid, zida zonyamula katundu ndizomwe zimagwiritsidwa ntchito kwambiri, zomwe zimapitilira 65% yazomwe zimagwiritsidwa ntchito. Ndi kusintha kwa chidziwitso cha chilengedwe komanso zofunikira za chitukuko chokhazikika, kugwiritsa ntchito asidi wa polylactic m'munda wolongedza kukuyembekezeka kuwonjezereka. Panthawi imodzimodziyo, minda yogwiritsira ntchito ziwiya zodyera, nsalu za fiber / zosalukidwa, zipangizo zosindikizira za 3D, ndi zina zotero zaperekanso malo atsopano a msika wa polylactic acid. Malinga ndi zomwe zimafunikira kwenikweni, mothandizidwa ndi zoletsa za pulasitiki ndi malamulo oletsa maboma m'maiko ndi zigawo zosiyanasiyana, kufunikira kwapadziko lonse kwa mapulasitiki owonongeka kupitilira kukula. Kufunika kwa asidi a polylactic pamsika wa China mu 2022 akuyembekezeka kufika matani 400000, ndipo akuyembekezeka kufika matani 2.08 miliyoni pofika chaka cha 2025. Pakalipano, malo akuluakulu ogwiritsira ntchito polylactic acid ndi zipangizo zonyamula katundu, zomwe zimawerengera 65% ya kugwiritsidwa ntchito konse; Chotsatira ndi ntchito monga ziwiya zodyera, nsalu za fiber/zosalukidwa, ndi zida zosindikizira za 3D. Europe ndi North America ndiye misika yayikulu kwambiri ya PLA, pomwe dera la Asia Pacific ndi amodzi mwamisika yomwe ikukula mwachangu.

Malo amsika a polylactic acid

Kupititsa patsogolo kuzindikira kwachilengedwe kumalimbikitsa kukula kwa msika: Ndikukula kwachidziwitso chachilengedwe padziko lonse lapansi, kufunikira kwa zinthu zomwe zingawonongeke kukupitiliza kukwera. Asidi ya polylactic, monga chinthu chochokera kuzinthu zongowonjezedwanso komanso kuwonongeka kwachilengedwe m'chilengedwe, imakondedwa kwambiri ndi mafakitale ndi ogula.

Kuthekera kwachitukuko m'malo mwa mapulasitiki achikhalidwe: Asidi a polylactic ali ndi biodegradability yabwino ndi biocompatibility, ndipo angagwiritsidwe ntchito m'malo mwa zinthu zapulasitiki zotayidwa monga matumba apulasitiki, tableware, zida zonyamula, etc. Chifukwa chake, ili ndi kuthekera kwakukulu kwachitukuko pazofunikira za tsiku ndi tsiku ndi mafakitale onyamula.

Kuwongolera kosalekeza kwa zinthu zakuthupi: Ndi kupita patsogolo kwa teknoloji, ntchito ya polylactic acid yakhala ikuwongolera mosalekeza, makamaka ponena za mphamvu, kukana kutentha, ndi kusinthika, kupititsa patsogolo kwambiri ndikukulitsa ntchito zake zosiyanasiyana, monga kusindikiza kwa 3D, zipangizo zamankhwala, ndi zina.

Thandizo la ndondomeko ndi chitukuko cha mafakitale: Mayiko ndi zigawo zina zimalimbikitsa kugwiritsa ntchito zinthu zowonongeka pogwiritsa ntchito ndondomeko ndi malamulo, zomwe zimalimbikitsa kukula kwa msika wa polylactic acid. Pakadali pano, ndikusintha kosalekeza kwa ma chain chain ndikuchepetsanso mtengo, msika wa polylactic acid udzakhala wampikisano.

Kuyang'ana madera omwe akugwiritsidwa ntchito: Polylactic acid sikuti imakhala ndi msika pazoyika zachikhalidwe komanso zofunikira zatsiku ndi tsiku, komanso ili ndi chiyembekezo chogwiritsa ntchito pakusintha nthaka, zida zamankhwala, nsalu, ndi zina. M'tsogolomu, kufufuza minda yomwe ikubwera kudzapititsa patsogolo kufunika kwa msika.

Ponseponse, monga chinthu chosawonongeka, asidi a polylactic ali ndi chiyembekezo chabwino chakukula kwa msika, makamaka ndikulimbikitsa chidziwitso cha chilengedwe, kusintha kwaukadaulo, ndikuthandizira mfundo. Msika wa polylactic acid ukuyembekezeka kubweretsa mwayi wambiri wachitukuko.

Mabizinesi akuluakulu mumakampani opanga nsalu za PLA

Mabizinesi akuluakulu padziko lonse lapansi omwe angawonongekePLA sanali nsalu nsalu makampani, kuphatikizapo Asahi Kasei Corporation, Qingdao Vinner New Materials, Foshan Membrane Technology, Great Lakes Filters, eSUN Bio Material, WINIW Nonwoven Materials, Foshan Guide Textile, D-TEX Nonwovens, Fujian Greenjoy Biomaterial, Techtex, TotalEnergies Industrial Corbion, National Bridges Corbion.

Mavuto Omwe Akukumana ndi Makampani a PLA Nonwovens

Ngakhale pali chiyembekezo chakukula, makampani a PLA nonwovens amakumana ndi zovuta zina. Vuto limodzi lalikulu ndi mtengo wopangira. PLA pakadali pano ndiyokwera mtengo kupanga poyerekeza ndi zida zachikhalidwe zosawoka. Komabe, kupita patsogolo kwaukadaulo ndi zachuma zikuyembekezeka kutsitsa mtengo wopangira mtsogolo. Vuto lina ndi kupezeka kochepa kwa zipangizo. PLA imachokera kuzinthu zongowonjezwdwa, ndipo kusinthasintha kulikonse komwe kulipo kungakhudze kukula kwamakampani.

Environmental Impact ya PLA Nonwovens

Mphamvu zachilengedwe za PLA nonwovens (PLA nonwoven nsalu mwambo) ndichinthu chofunikira kwambiri kuchiganizira. PLA imachokera kuzinthu zongowonjezedwanso ndipo imakhala ndi mpweya wocheperako poyerekeza ndi zida zopangira mafuta. PLA nonwovens ndi compostable ndi kusweka mu zigawo zachilengedwe pansi pa mikhalidwe yeniyeni. Khalidweli limachepetsa kuchuluka kwa zinyalala zosawonongeka m'malo otayirako ndikupangitsa kuti tsogolo likhale lokhazikika. Komabe, ndikofunikira kuwonetsetsa kuti njira zoyendetsera zinyalala zili m'malo kuti ziwonjezeke mapindu a PLA nonwovens.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
