1. Chidule cha unyolo wa mafakitale:
Dzina lonse la polylactic acid ndi polylactic acid kapena polylactic acid. Ndi chinthu cha polyester chokhala ndi mamolekyulu ambiri chomwe chimapezeka popangidwa ndi lactic acid kapena lactic acid dimer lactide ngati monomer. Ndi cha zinthu zopangidwa ndi mamolekyulu ambiri ndipo chili ndi makhalidwe achilengedwe komanso kuwonongeka. Pakadali pano, polylactic acid ndi pulasitiki yosinthika yomwe ikukula kwambiri, yotulutsa kwambiri komanso yogwiritsidwa ntchito kwambiri padziko lonse lapansi. Makampani opanga ma polylactic acid ndi mitundu yonse ya zinthu zoyambira, monga chimanga, nzimbe, beet, ndi zina zotero, pakati pake ndi kukonzekera polylactic acid, ndipo pansi pake ndi kugwiritsa ntchito polylactic acid, kuphatikiza mbale zotetezera chilengedwe, ma CD oteteza chilengedwe, ndi zina zotero.
2. Makampani otsogola
Pakadali pano, zinthu zopangira polylactic acid m'nyumba ndi lactic acid, ndipo lactic acid imapangidwa kwambiri kuchokera ku chimanga, nzimbe, beet ndi zinthu zina zaulimi. Chifukwa chake, makampani obzala mbewu omwe amatsogoleredwa ndi chimanga ndi makampani otsogola a polylactic acid industrial. Kuchokera ku malingaliro a malo obzala chimanga ku China, zokolola za chimanga ku China zidzafika matani 272.55 miliyoni mu 2021, ndi kukula kwakukulu, ndipo malo obzala akhala okhazikika pa mahekitala 40-45 miliyoni kwa zaka zambiri. Kuchokera ku chakudya cha chimanga ku China chomwe chimapezeka kwa nthawi yayitali, tikuyembekeza kuti chakudya cha chimanga chidzakhala chokhazikika mtsogolo.
Ponena za zinthu zina zopangira zomwe zingagwiritsidwe ntchito popanga lactic acid, monga nzimbe ndi shuga beet, kuchuluka kwa zinthu zomwe China idatulutsa mu 2021 kunali matani 15.662 miliyoni, zomwe zinali zochepa kuposa zaka zam'mbuyomu, koma zinalibe pamlingo wabwinobwino. Ndipo makampani padziko lonse lapansi akufufuzanso njira zatsopano zopangira lactic acid, monga kugwiritsa ntchito gwero la shuga mu ulusi wamatabwa monga udzu ndi utuchi kuti akonze lactic acid kapena kufufuza njira yogwiritsira ntchito methane popanga lactic acid. Ponseponse, kupezeka kwa polylactic acid m'makampani apamwamba kudzakhala kokhazikika mtsogolo.
3. Makampani apakati
Popeza ndi chinthu chowola bwino, polylactic acid imatha kubweretsa zinthu zopangira mu njira yobwezeretsanso zinthu ndi kubwezeretsanso, yomwe ili ndi ubwino womwe zinthu zopangidwa ndi mafuta sizili nawo. Chifukwa chake, kugwiritsa ntchito polylactic acid pamsika wamkati kukuwonjezeka. Kugwiritsa ntchito m'nyumba mu 2021 ndi matani 48071.9, kuwonjezeka kwa 40% pachaka.
Chifukwa cha mphamvu yochepa yopangira polylactic acid ku China, kuchuluka kwa polylactic acid ku China kuli kwakukulu kwambiri kuposa kuchuluka kwa mafuta otumizidwa kunja. M'zaka zaposachedwa, kuchuluka kwa polylactic acid ku China kwakwera mofulumira chifukwa cha kufunikira kwa dzikolo. Mu 2021, mafuta otumizidwa kunja a polylactic acid anafika matani 25294.9. Kutumiza kunja kwa polylactic acid kunapitanso patsogolo kwambiri mu 2021, kufika matani 6205.5, kuwonjezeka kwa 117% pachaka.
Lipoti lofanana: lipoti la kusanthula momwe zinthu zikuyendera pa chitukuko ndi kuneneratu za chitukuko cha makampani opanga zinthu za polylactic acid ku China kuyambira 2022 mpaka 2028 loperekedwa ndi Zhiyan consulting
4. Makampani otsika
Mu ntchito zoyambira pansi, polylactic acid yagwiritsidwa ntchito m'magawo ambiri chifukwa cha kuyanjana kwake ndi chilengedwe komanso kuwonongeka kwake. Pakadali pano, yagwiritsidwa ntchito kwambiri pakulongedza zakudya, mbale zophikira, ma CD a matumba a filimu ndi zinthu zina ndi minda. Mwachitsanzo, filimu ya pulasitiki yaulimi yopangidwa ndi polylactic acid imatha kuwonongeka kwathunthu ndikutha pambuyo pokolola mbewu, zomwe sizingachepetse kuchuluka kwa madzi ndi chonde m'nthaka, komanso kupewa ndalama zowonjezera zantchito ndi ntchito zomwe zimafunikira kuti filimu ya pulasitiki ibwezeretsedwe, zomwe ndi njira yodziwika bwino yopangira filimu ya pulasitiki ku China mtsogolo. Malo omwe filimu ya pulasitiki imaphimbidwa ndi filimu ya pulasitiki ku China ndi pafupifupi mahekitala 18000, ndipo kugwiritsa ntchito filimu ya pulasitiki mu 2020 ndi matani 1357000. Filimu ya pulasitiki yowonongeka ikangotchuka, makampani a polylactic acid ali ndi malo akuluakulu oti apangidwe mtsogolo.
