1. Uhlolojikelele lochungechunge lwezimboni:
Igama eligcwele le-polylactic acid i-poly lactic acid noma i-poly lactic acid. Kuyinto ephezulu ye-polyester yamangqamuzana etholwe ngokwenza i-polymerization nge-lactic acid noma i-lactic acid dimer lactide njenge-monomer. Iyingxenye ye-synthetic high molecular material futhi inezici zesisekelo sebhayoloji kanye nokuwohloka. Njengamanje, i-polylactic acid iyipulasitiki ebolayo enezimboni ezivuthwe kakhulu, umkhiqizo omkhulu futhi osetshenziswa kakhulu emhlabeni. Imboni ekhuphukayo ye-polylactic acid yizo zonke izinhlobo zezinto zokusetshenziswa eziyisisekelo, ezifana nommbila, umoba, isithombo sebhitrudi, njll., ukufinyelela okuphakathi kuwukulungiswa kwe-polylactic acid, kanti umfula ongezansi ikakhulukazi ukusetshenziswa kwe-polylactic acid, kuhlanganise nokuvikelwa kwemvelo. i-tableware, ukupakishwa kokuvikela imvelo, njll.
2. Imboni ekhuphuka nomfula
Njengamanje, imboni ye-polylactic acid yasekhaya i-lactic acid, kanti i-lactic acid ilungiswa kakhulu kusuka kummbila, umoba, isithombo sebhitrudi neminye imikhiqizo yezolimo. Ngakho-ke, imboni yokutshala izitshalo ephethwe ummbila iyimboni ekhuphukayo yochungechunge lwezimboni ze-polylactic acid. Ngokombono wendawo yokutshala ummbila waseShayina kanye nendawo yokutshala, umkhiqizo wokutshala ummbila waseShayina uzofinyelela kumathani ayizigidi ezingama-272.55 ngo-2021, ngesilinganiso esikhulu, futhi indawo yokutshala izinzile kumahektha ayizigidi ezingama-40-45 iminyaka eminingi. Kusukela ekuhlinzekeni isikhathi eside kommbila e-China, kungalindelwa ukuthi ukuhlinzekwa kommbila kuzohlala kuzinzile esikhathini esizayo.
Ngokuqondene nezinye izinto zokusetshenziswa ezingasetshenziswa ukukhiqiza acid lactic, ezifana umoba kanye ushukela isithombo sebhitrudi, okukhipha ingqikithi China ngo-2021 kwaba 15.662 million amathani, okuyinto yayiphansi kunaleyo eminyakeni eyedlule, kodwa namanje ezingeni evamile. Futhi amabhizinisi emhlabeni wonke ahlola futhi ngenkuthalo izindlela ezintsha zokwenza i-lactic acid, njengokusebenzisa umthombo kashukela emicu yezinkuni njengotshani namasaha ukuze kulungiswe i-lactic acid noma ukuhlola indlela yokusebenzisa i-methane ukukhiqiza i-lactic acid. Sekukonke, ukuhlinzekwa kwemboni ekhuphuka nomfula ye-polylactic acid kuzozinza ngokuzayo.
3. Imboni ephakathi nendawo
Njengento ebolayo ngokuphelele, i-polylactic acid ingaletha ukuphela kwezinto ezingavuthiwe ohlelweni lokuvuselelwa kabusha kwensiza kanye nohlelo lokugaywa kabusha, olunezinzuzo ezingenazo izinto ezisekelwe ku-petroleum. Ngakho-ke, ukusetshenziswa kwe-polylactic acid emakethe yasekhaya kuyanda. Ukusetshenziswa kwasekhaya ngo-2021 kungamathani angama-48071.9, okuwukunyuka kwama-40% unyaka nonyaka.
Ngenxa yomthamo ophansi wokukhiqiza we-polylactic acid e-China, inani le-polylactic acid e-China likhulu kakhulu kunenani elithunyelwa ngaphandle. Eminyakeni yamuva nje, inani lokungenisa le-polylactic acid likhuphuke ngokushesha liqhutshwa isidingo sasekhaya. Ngo-2021, ukungeniswa kwe-polylactic acid kwafinyelela kumathani angama-25294.9. Ukuthunyelwa kwamanye amazwe kwe-polylactic acid nakho kwaba nenqubekelaphambili enkulu ngo-2021, yafinyelela kumathani angama-6205.5, okuwukunyuka konyaka ngo-117%.
Umbiko ohlobene: umbiko wokuhlaziywa kwethrendi yentuthuko kanye nokubikezela kwethemba lokuthuthuka komkhakha womkhiqizo we-polylactic acid waseChina kusukela ngo-2022 kuya ku-2028 okhishwe nguZhiyan consulting.
4. Imboni ye-downstream
Ekusetshenzisweni komfula, i-polylactic acid isetshenziswe emikhakheni eminingi nge-biocompatibility yayo eyingqayizivele kanye ne-biodegradability. Njengamanje, isetshenziswe kabanzi ekufakweni kwezinga lokuthintana nokudla, i-tableware, isikhwama sefilimu kanye neminye imikhiqizo nezinkambu. Isibonelo, ifilimu yepulasitiki yezolimo eyenziwe nge-polylactic acid ingacekelwa phansi ngokuphelele futhi inyamalale ngemuva kokuvunwa kwezitshalo, okungeke kunciphise okuqukethwe kwamanzi nokuvunda kwenhlabathi, kodwa futhi kugweme izindleko ezengeziwe zomsebenzi kanye nokusebenza okudingekayo ukuze kubuyiswe kabusha. ifilimu yepulasitiki, okuwumkhuba ojwayelekile wokuthuthukiswa kwefilimu yepulasitiki eChina esikhathini esizayo. Indawo embozwe ifilimu yepulasitiki eChina ingamahektha ayi-18000, kanti ukusetshenziswa kwefilimu yepulasitiki ngo-2020 kungamathani ayi-1357000. Uma ifilimu yepulasitiki eyonakalayo seyidume kakhulu, imboni ye-polylactic acid inesikhala esikhulu sokuthuthuka esikhathini esizayo.
