1. Chidule cha unyolo wa mafakitale:
Dzina lonse la polylactic acid ndi poly lactic acid kapena poly lactic acid. Ndi mkulu maselo poliyesitala zakuthupi anapezedwa polymerization ndi lactic acid kapena lactic asidi dimer lactide monga monoma. Ndiwopangidwa ndi ma molekyulu apamwamba kwambiri ndipo ali ndi mawonekedwe achilengedwe komanso kuwonongeka. Pakadali pano, asidi wa polylactic ndi pulasitiki wosasinthika wokhala ndi mafakitale okhwima kwambiri, otulutsa kwambiri komanso omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi. Kumtunda kwa polylactic asidi makampani ndi mitundu yonse ya zipangizo zofunika, monga chimanga, nzimbe, beet shuga, etc., pakati amafika ndi yokonza asidi polylactic, ndi kunsi kwa mtsinje makamaka ntchito polylactic asidi, kuphatikizapo kuteteza chilengedwe. tableware, ma CD oteteza zachilengedwe, etc.
2. Makampani akumtunda
Pakali pano, zopangira za m'banja polylactic asidi makampani ndi lactic acid, ndi asidi lactic makamaka anakonza kuchokera chimanga, nzimbe, shuga beet ndi zina zaulimi. Chifukwa chake, makampani obzala mbewu omwe amalamulidwa ndi chimanga ndi makampani akumtunda a polylactic acid mafakitale. Kutengera momwe chimanga cha China chimalima ndikubzala, mbewu yaku China yobzala chimanga idzafika matani 272.55 miliyoni mu 2021, ndi gawo lalikulu, ndipo malo obzala akhala okhazikika pa mahekitala 40-45 miliyoni kwa zaka zambiri. Kuchokera ku nthawi yayitali ya chimanga ku China, zikhoza kuyembekezera kuti kuperekedwa kwa chimanga kudzakhalabe kokhazikika m'tsogolomu.
Koma zopangira zina zomwe zingagwiritsidwe ntchito popanga asidi lactic, monga nzimbe ndi beet shuga, linanena bungwe okwana China mu 2021 anali 15.662 miliyoni matani, amene anali m'munsi kuposa zaka zapitazo, koma pa mlingo wabwinobwino. Ndipo mabizinesi padziko lonse lapansi akufufuzanso mwachangu njira zatsopano zopangira lactic acid, monga kugwiritsa ntchito gwero la shuga mu ulusi wamatabwa monga udzu ndi utuchi pokonzekera lactic acid kapena kufufuza njira yogwiritsira ntchito methane kupanga lactic acid. Pazonse, kupezeka kwa makampani akumtunda kwa polylactic acid kudzakhala kokhazikika mtsogolo.
3. Makampani apakati
Monga zinthu zomwe zimatha kuwonongeka kwathunthu, asidi a polylactic amatha kubweretsa kutha kwazinthu zopangira zida zosinthika ndikubwezeretsanso, zomwe zili ndi zabwino zomwe zida zamafuta zilibe. Chifukwa chake, kumwa kwa polylactic acid pamsika wakunyumba kukukulirakulira. Zomwe zimagwiritsidwa ntchito m'nyumba mu 2021 ndi matani 48071.9, kuwonjezeka kwa 40% pachaka.
Chifukwa cha kuchepa kwa asidi a polylactic ku China, kuchuluka kwa asidi wa polylactic ku China ndi kwakukulu kwambiri kuposa kuchuluka kwa kunja. M'zaka zaposachedwa, kuchuluka kwa asidi wa polylactic wakwera kwambiri chifukwa cha kufunikira kwapakhomo. Mu 2021, kulowetsedwa kwa asidi wa polylactic kudafika matani 25294.9. Kutumiza kwa polylactic acid kudapitanso patsogolo kwambiri mu 2021, kufikira matani 6205.5, kuwonjezeka kwa chaka ndi 117%.
Lipoti lofananira: lipoti la kusanthula kwachitukuko ndi kuneneratu kwachitukuko kwamakampani aku China polylactic acid kuyambira 2022 mpaka 2028 loperekedwa ndi Zhiyan consulting
4. Makampani otsika
M'malo otsika, asidi a polylactic agwiritsidwa ntchito m'magawo ambiri ndi biocompatibility yake yapadera komanso kuwonongeka kwachilengedwe. Pakali pano, wakhala chimagwiritsidwa ntchito chakudya kukhudzana mlingo ma CD, tableware, filimu thumba ma CD ndi zinthu zina ndi minda. Mwachitsanzo, filimu yapulasitiki yaulimi yopangidwa ndi asidi ya polylactic imatha kunyonyotsoka ndikuzimiririka pambuyo pokolola mbewu, zomwe sizingachepetse kuchuluka kwa madzi ndi chonde m'nthaka, komanso kupewa ndalama zowonjezera zogwirira ntchito ndi ntchito zomwe zimafunikira kuti abwezeretsedwe. filimu ya pulasitiki, yomwe ndizochitika zambiri za chitukuko cha filimu ya pulasitiki ku China m'tsogolomu. Dera lomwe lili ndi filimu yapulasitiki ku China ndi pafupifupi mahekitala 18000, ndipo kugwiritsa ntchito filimu yapulasitiki mu 2020 ndi matani 1357000. Kanema wapulasitiki wowonongeka akatha kutchuka, makampani a polylactic acid amakhala ndi malo akulu otukuka mtsogolo.
