1. Isishwankathelo sekhonkco lemizi-mveliso:
Igama elipheleleyo le-polylactic acid yi-polylactic acid okanye i-polylactic acid. Yinto ye-polyester enemolekyuli ephezulu efunyenwe yi-polymerization nge-lactic acid okanye i-lactic acid i-dimer lactide njenge-monomer. Yeyezinto ezenziwe ngemolekyuli ephezulu kwaye ineempawu zebhayoloji kunye nokubola. Okwangoku, i-polylactic acid yiplastiki ebolayo enophuhliso oluvuthiweyo, imveliso enkulu kwaye isetyenziswa kakhulu kwihlabathi liphela. Ishishini le-polylactic acid liphezulu kuzo zonke iintlobo zezinto ezisisiseko, ezifana nombona, umoba, iswekile, njl., indawo ephakathi kukulungiswa kwe-polylactic acid, kwaye ezantsi kukusetyenziswa kwe-polylactic acid, kubandakanya izitya zokukhusela okusingqongileyo, ukupakishwa kokukhusela okusingqongileyo, njl.
2. Ishishini elinyukayo
Okwangoku, izinto ezisetyenziswa kwishishini le-polylactic acid yasekhaya yi-lactic acid, kwaye i-lactic acid ilungiselelwe kakhulu ngombona, umoba, i-beet yeswekile kunye nezinye iimveliso zezolimo. Ke ngoko, ishishini lokutyala izityalo elilawulwa yi-corn lishishini eliphambili le-polylactic acid industrial chain. Ngokwembono yemveliso yombona kunye nendawo yokutyala yaseTshayina, imveliso yokutyala umbona yaseTshayina iya kufikelela kwiitoni ezingama-272.55 ezigidi ngo-2021, ngomlinganiselo omkhulu, kwaye indawo yokutyala ibizinzile kwiihektare ezingama-40-45 ezigidi kangangeminyaka emininzi. Ngokwenkxaso yombona yexesha elide eTshayina, kunokulindeleka ukuba umbone uya kuhlala uzinzile kwixesha elizayo.
Ngokuphathelele ezinye izinto ezingasetyenziswa ukuvelisa i-lactic acid, ezifana nomoba kunye ne-sugar beet, imveliso iyonke yaseTshayina ngo-2021 yayiziitoni ezili-15.662 ezigidi, nto leyo eyayiphantsi kunaleyo kwiminyaka edlulileyo, kodwa isekwinqanaba eliqhelekileyo. Kwaye amashishini kwihlabathi liphela ahlola ngenkuthalo iindlela ezintsha zokulungisa i-lactic acid, njengokusebenzisa umthombo weswekile kwimicu yomthi efana nomququ kunye nothuli lwesawdust ukulungiselela i-lactic acid okanye ukuhlola indlela yokusebenzisa i-methane ukuvelisa i-lactic acid. Lilonke, ukunikezelwa kwe-polylactic acid kushishino oluphezulu kuya kuba kuzinzile kwixesha elizayo.
3. Ishishini eliphakathi
Njengezinto ezinokubola ngokupheleleyo, i-polylactic acid ingazisa izinto eziluhlaza kwinkqubo yokuhlaziya nokuhlaziya izixhobo, enezibonelelo ezingenazo izinto ezisekelwe kwi-petroleum. Ke ngoko, ukusetyenziswa kwe-polylactic acid kwimarike yasekhaya kuyanda. Ukusetyenziswa kwasekhaya ngo-2021 yi-48071.9 yeetoni, ukunyuka kwe-40% ngonyaka.
Ngenxa yomthamo ophantsi wemveliso ye-polylactic acid eTshayina, ubungakanani bokungenisa i-polylactic acid eTshayina bukhulu kakhulu kunobungakanani bokuthumela ngaphandle. Kwiminyaka yakutshanje, ubungakanani bokungenisa i-polylactic acid bunyuke ngokukhawuleza ngenxa yemfuno yasekhaya. Ngo-2021, ukungeniswa kwe-polylactic acid kufikelele kwiitoni ezingama-25294.9. Ukuthunyelwa kwe-polylactic acid kwamanye amazwe nako kwenze inkqubela phambili enkulu ngo-2021, kwafikelela kwiitoni ezingama-6205.5, ukunyuka konyaka nonyaka kwe-117%.
Ingxelo enxulumeneyo: ingxelo malunga nohlalutyo lwemikhwa yophuhliso kunye noqikelelo lwamathemba ophuhliso lweshishini lemveliso ye-polylactic acid yaseTshayina ukususela ngo-2022 ukuya ku-2028 ekhutshwe yiZhiyan consulting
4. Ishishini elisezantsi
Kwizicelo ezisezantsi, i-polylactic acid isetyenzisiwe kwiindawo ezininzi ngenxa yokuhambelana kwayo okungaqhelekanga kunye nokubola kwayo. Okwangoku, isetyenziswa kakhulu ekupakisheni ukutya, kwiitafile, kwiingxowa zefilimu nakwezinye iimveliso kunye namasimi. Umzekelo, ifilimu yeplastiki yezolimo eyenziwe nge-polylactic acid inokonakala ngokupheleleyo kwaye inyamalale emva kokuvunwa kwezityalo, nto leyo engayi kunciphisa umxholo wamanzi kunye nokuchuma komhlaba, kodwa ikwaphephe iindleko ezongezelelweyo zomsebenzi kunye nokusebenza ezifunekayo ekubuyiselweni kwefilimu yeplastiki, nto leyo eyindlela eqhelekileyo yophuhliso lwefilimu yeplastiki eTshayina kwixesha elizayo. Indawo egutyungelwe yifilimu yeplastiki eTshayina imalunga neehektare ezili-18000, kwaye ukusetyenziswa kwefilimu yeplastiki ngo-2020 yi-1357000 yeetoni. Nje ukuba ifilimu yeplastiki ebolayo ikwazi ukuthandwa, ishishini le-polylactic acid linendawo enkulu yophuhliso kwixesha elizayo.
