INGXOXO EMFUSHANE NGEZITSHA ZOKUDLA IZITSHA

INDLELA ENHLE YOKUSEBENZISA IMVELO, KUDINGEKA KUBE “NGOKUFANELE”

Nkulezi zinsuku, ngingena ezitolo zekhofi, “Izinti ezibolayo ze-PLA"akuseyona into entsha. Abantu abaningi banokungabaza okunjalo lapho behlangana nemikhiqizo enjalo:Kungani izinti ze-PLA ezibhalwe ukuthi “ziyabola” zingaboli isikhathi eside uma ziphonswa endaweni yemvelo?Ikuphi ngempela ukubaluleka kwayo kwezemvelo? Eqinisweni, izimfanelo zemvelo ze-PLA aziyona "icebo", kodwa zidinga ukusekelwe ekuqondeni kwesayensi nasekusetshenzisweni okufanele. Namuhla, ngokombono wemboni, sizoxoxa kafushane ngenani eliyinhloko, imingcele yokusetshenziswa kanye namaphuzu abalulekile okuwohloka kwe-PLA straws..

Kuyini i-PLA? I-Alchemy Yesimanje Evela Emvelweni

PI-LA, isifinyezo se-polylactic acid, iyinto ebolayo esuselwa ku-bio. Izinto zayo zokusetshenziswa zitholakala ezitshalweni zesitashi ezifana nommbila kanye ne-cassava, eziguqulwa zibe izinto ze-polymer ezinamandla aphezulu ngokubilisa, ukuhlanzwa kanye ne-polymerization, zakha umjikelezo wokuqala ovaliwe "ovela emvelweni". Ngokungafani nepulasitiki yendabuko ethembele kuphethiloli, isici sayo esivuselelekayo yinzuzo eyinhloko.

Ngokusho kwedatha evela kwi-China Plastics Processing Industry Association, ukukhiqiza ithani eli-1 le-PLA kunganciphisa amathani angu-2.1 okusetshenziswa kukaphethiloli kanye namathani angu-3.2 okukhishwa kwekhabhoni. Lo mphumela wokunciphisa ikhabhoni uqashelwa yizimakethe zomhlaba wonke, futhi futhi yisona sizathu esiyinhloko sokuthi izinkampani ezihamba phambili zetiye lobisi lwasekhaya zilithatha njengenye indlela eyinhloko esikhundleni se-straw yepulasitiki.

Isithembiso: Intuthuko Yangempela Isipho Se-PLA Straws

FOkokuqala, banikeza ulwazi olungcono.Abaningi bakhumbula izinkinga ngama-straw ephepha—athambile futhi athambile ngemva kwemizuzu engamashumi amabili ephuzweni. Ama-straw e-PLA axazulula lokhu kakhulu. Aqinile, awanambitheki, futhi azwakala efana nepulasitiki yendabuko, okusho ukuthi “enobungani nemvelo” akusadingeki azizwe sengathi ayavumelana.

Okwesibili, banesiphelo esicacile sesayensi.Ngaphansi kokufanelekaukwenziwa komquba ezimboniniUma izimo zivuma, indlela yokuwohloka kwe-PLA ichazwe kahle. Izikhungo ezikhethekile zinikeza ukushisa okuqhubekayo (55-70°C), umswakama oqondile, kanye nama-microbes athile. Lapha,Izitsha ze-PLAngokuvamile zihlukana zibe yi-carbon dioxide, amanzi, kanye ne-biomass zingakapheli izinsuku ezingu-90 kuya kwezingu-180, ziqedela umjikelezo osuka esitshalweni ubuyele emhlabeni.

Okubaluleke kakhulu, bashintsha umthombo.Ukukhiqiza ithani elilodwa le-PLA kungonga cishe amathani amabili kaphethiloli futhi kunciphise ukukhishwa kwekhabhoni ngamathani angaphezu kwamathathu. Kumelela umjikelezo: kusukela ekumbeni izinqolobane zasendulo kuya ekusebenziseni izinsiza zezitshalo ezivuselelekayo minyaka yonke.

Imingcele Yokusetshenziswa: Ayiyona “Eyonakalayo Yonke Indawo”, Idinga Ukulungiswa Kwesimo

Inkinga ilele ngqo kulezo “zimo ezinhle.”

Ukungaqondani okuningi nge-PLA kuvela ekulinganiseni "okubolayo" "nokubola kunoma iyiphi indawo". Lokho okubizwa ngokuthi "ububi" empeleni kuyimingcele yezindawo:

Ngokuphathelene nokushisa, izinga lokushisa lokushintsha kwengilazi le-PLA licishe libe ngu-50℃, lithamba kalula futhi liguquguquke uma lidlula leli zinga lokushisa, lifanele kuphela iziphuzo ezibandayo. Izinguqulo ezimelana nokushisa okuphezulu zidinga iziguquli, okunciphisa ukusebenza kahle kokubola ngo-10%-30%. Ngokuphathelene nendawo ezungezile, ukubola kwayo kuncike ezitshalweni ezithile ekuhlanganiseni izimboni, ngomjikelezo wokubola weminyaka engaphezu kwengu-50 enhlabathini yokushisa evamile, futhi amadolobha ambalwa kuphela asekhaya anezindawo zokwelashwa ezinkulu. Ngokuphathelene nezindleko, intengo yamanje yeyunithi yama-straw e-PLA ingu-0.08-0.1 yuan, izikhathi eziphindwe kathathu kuya kahlanu kunezepulasitiki zendabuko, futhi izindleko kulindeleke ukuthi zehle ngaphezu kuka-30% ngemuva kokwandiswa kwamandla ngo-2026.

Umbono Olinganiselayo: Lokho Okuyikho Nokuthi Akusikho Ukutshaya Kwe-PLA

PAma-straw e-LA amelela ubuchwepheshe obushintshayo obuwusizo, kodwa awayona inhlamvu yesiliva. Ayisihluthulelo esisebenza kuphela uma sifanelana nokhiye—uhlelo lokucubungula imfucuza oluhambisanayo. Kubathengi: Baphathe njengomfudlana wemfucuza okhethekile. Funa isitifiketi esithembekile esingafakwa umquba (njenge-BPI) bese ulandela isiqondiso sendawo sokulahla imfucuza yokudla noma amabhokisi aluhlaza aqondiswe ezindaweni zezentengiselwano.

Embonini: Ziqokomisa ukuthi ukusungula izinto ezintsha kuphela akwanele. Izixazululo eziphelele zidinga ushintsho oluhlelekile: ukwakheka komkhiqizo okungcono, imfundo yabathengi, kanye, okubaluleke kakhulu, ukutshalwa kwezimali engqalasizinda yokwenza umquba.

Isinyathelo Esibalulekile Ekuguqulweni Kwemvelo

PI-LA ayisona isisombululo esiphelele semvelo, kodwa iphula ukuqonda ukuthi "ukuvikelwa kwemvelo kumele kulahle ulwazi" futhi inikeza indlela engenzeka yokushintsha ipulasitiki. Ngokusakazwa kotshani be-PLA, imboni yezokupheka yasekhaya inciphisa imfucuza yepulasitiki ngamathani angaphezu kuka-120,000 ngonyaka, iqoqa ulwazi lokushintsha ezinye izigaba. Ngokuthuthuka kobuchwepheshe nezindawo, i-PLA izoqhubeka nokunika amandla ukuguqulwa kwemvelo, isebenza njengebhuloho elibalulekile phakathi kwezinto eziluhlaza zamanje nezesikhathi esizayo.

Izihloko Ezihlobene:

Ukucwila Okujulile Kwemboni|Imakethe YamaRandi Ayizigidi Eziyizigidi Ezingama-32 ngo-2034: Ukuphakama Okugcwele Kwe-Bioplastic Packaging Kusukela “Kumqondo Oluhlaza” Kuya “Ku-Commercial Mainstream”

Ama-Paper Straws Angase Angabi Yimpendulo Ephelele, Kodwa Ingabe Ukubuyela Enkathini Yepulasitiki Kungaba Ngcono?
