1. Isishwankathelo sekhonkco lemizi-mveliso:
Igama elipheleleyo le-polylactic acid yi-poly lactic acid okanye i-poly lactic acid. Yimpahla ephezulu ye-molecular polyester efunyenwe yi-polymerization nge-lactic acid okanye i-lactic acid dimer lactide njenge-monomer. Yeyokwenziwa kwemathiriyeli yemolekyuli ephezulu kwaye ineempawu zebhayoloji kunye nokuthotywa. Okwangoku, i-polylactic acid yiplastiki enokubola kunye neyona mveliso ikhulileyo, imveliso enkulu kunye neyona isetyenziswa kakhulu kwihlabathi. Umphezulu wemveliso ye-polylactic acid yizo zonke iintlobo zezinto ezisisiseko, ezifana nombona, ummoba, i-beet yeswekile, njl., Ukufikelela phakathi kukulungiswa kwe-polylactic acid, kwaye ezantsi kusetyenziso lwe-polylactic acid, kubandakanywa nokukhuselwa kokusingqongileyo. i-tableware, ukupakishwa kokhuseleko lokusingqongileyo, njl.
2. Ushishino oluphezulu
Okwangoku, izinto eziluhlaza kwishishini le-polylactic acid yasekhaya yi-lactic acid, kwaye i-lactic acid ilungiswa kakhulu ukusuka kumbona, ummoba, i-beet yeswekile kunye nezinye iimveliso zezolimo. Ke ngoko, ishishini lokutyala izityalo elilawulwa ngumbona lishishini elinyukayo le-polylactic acid yeshishini. Ngokwembono yemveliso yombona yaseTshayina kunye nommandla wokutyala, imveliso yokutyala umbona waseTshayina iya kufikelela kwi-272.55 yezigidi zeetoni ngo-2021, kunye nomlinganiselo omkhulu, kwaye indawo yokutyala izinzile kwi-40-45 yezigidi zeehektare iminyaka emininzi. Ukususela ekuboneleleni kwexesha elide lombona e-China, kunokulindelwa ukuba ukunikezelwa kombona kuya kuhlala kuzinzile kwixesha elizayo.
Ngokuphathelele ezinye izinto ekrwada ezinokusetyenziswa ukuvelisa acid lactic, ezifana ummoba kunye neswekile beet, imveliso China iyonke ngo-2021 yaba iitoni million 15.662, nto leyo yayingaphantsi kunaleyo kwiminyaka edlulileyo, kodwa kusekho kwinqanaba eqhelekileyo. Kwaye amashishini kwihlabathi jikelele ajongana neendlela ezintsha zokulungisa iasidi ye-lactic, njengokusebenzisa umthombo weswekile kwimicu yomthi efana neendiza kunye ne-sawdust ukulungisa i-lactic acid okanye ukukhangela indlela yokusebenzisa imethane ukuvelisa i-lactic acid. Ngokubanzi, ukunikezelwa kweshishini elinyukayo le-polylactic acid liya kuba lizinzile kwixesha elizayo.
3. Ishishini eliphakathi
Njengezinto eziguquguqukayo ngokupheleleyo, i-polylactic acid inokuzisa ukuphela kwezinto eziluhlaza kwi-resource regeneration kunye ne-recycling system, enenzuzo yokuba izinto ezisekelwe kwi-petroleum azinayo. Ngoko ke, ukusetyenziswa kwe-polylactic acid kwimarike yasekhaya kuyanda. Ukusetyenziswa kwasekhaya ngo-2021 yi-48071.9 yeetoni, ukwanda kwe-40% unyaka nonyaka.
Ngenxa yomthamo ophantsi wemveliso ye-polylactic acid e-China, ubungakanani bokungenisa kwe-polylactic acid e-China bukhulu kakhulu kunobuninzi bokuthunyelwa ngaphandle. Kwiminyaka yakutshanje, ubungakanani bokungenisa kwe-polylactic acid bunyuke ngokukhawuleza buqhutywa yimfuno yasekhaya. Kwi-2021, ukungeniswa kwe-polylactic acid kufikelele kwiitoni ze-25294.9. Ukuthunyelwa kwamanye amazwe kwe-polylactic acid kwenze inkqubela phambili enkulu ngo-2021, yafikelela kwiitoni ezingama-6205.5, ukunyuka konyaka-ngonyaka kwe-117%.
Ingxelo ehambelanayo: ingxelo kuhlalutyo lwendlela yophuhliso kunye nokuqikelelwa kwethemba lophuhliso lwemveliso yemveliso ye-polylactic acid yaseTshayina ukusuka ngo-2022 ukuya ku-2028 ekhutshwe nguZhiyan.
4. Ushishino olusezantsi
Kwizicelo ezisezantsi, i-polylactic acid isetyenziswe kwiinkalo ezininzi kunye ne-biocompatibility yayo ekhethekileyo kunye ne-biodegradability. Okwangoku, isetyenziswe ngokubanzi kwipakethe yenqanaba loqhagamshelwano lokutya, i-tableware, isikhwama sefilimu kunye nezinye iimveliso kunye namasimi. Ngokomzekelo, ifilimu yeplastiki yezolimo eyenziwe nge-polylactic acid inokutshatyalaliswa ngokupheleleyo kwaye ilahleke emva kokuvunwa kwezityalo, engayi kunciphisa umthamo wamanzi kunye nokuchuma komhlaba, kodwa iphinde igweme iindleko ezongezelelweyo zomsebenzi kunye nokusebenza okufunekayo ukuze kubuyiselwe kwakhona. ifilimu yeplastiki, yindlela eqhelekileyo yokuphuhliswa kwefilimu yeplastiki eChina kwixesha elizayo. Indawo egqunywe yifilimu yeplastiki eTshayina imalunga neehektare ezingama-18000, kwaye ukusetyenziswa kwefilimu yeplastiki ngo-2020 ziitoni ezingama-1357000. Nje ukuba ifilimu yeplastiki eyonakeleyo ikwazi ukuthandwa, ishishini le-polylactic acid linendawo enkulu yophuhliso kwixesha elizayo.
