Nniaj hnub nim no, taug kev mus rau hauv cov khw kas fes, "PLA cov straws biodegradable"tsis yog ib yam tshiab lawm. Muaj ntau tus neeg muaj kev tsis ntseeg thaum lawv kov cov khoom no:Vim li cas cov PLA straws uas muaj daim ntawv lo "biodegradable" thiaj tsis lwj mus ntev thaum muab pov rau hauv ib puag ncig ntuj?Nws tus nqi ib puag ncig nyob qhov twg tiag? Qhov tseeb, cov yam ntxwv ib puag ncig ntawm PLA tsis yog "kev dag ntxias", tab sis yuav tsum ua raws li kev paub txog kev tshawb fawb thiab kev siv kom raug. Niaj hnub no, los ntawm kev lag luam, peb yuav tham luv luv txog tus nqi tseem ceeb, cov ciam teb siv thiab cov ntsiab lus tseem ceeb ntawm PLA straws..

TSHOOJ I

PLA yog dab tsi? Kev Alchemy Niaj Hnub Nim No Los Ntawm Xwm

PLA, luv rau polylactic acid, yog ib yam khoom siv bio-based biodegradable. Nws cov khoom siv raw yog los ntawm cov qoob loo hmoov txhuv nplej siab xws li pob kws thiab cassava, uas raug hloov mus ua cov khoom siv polymer muaj zog siab los ntawm kev fermentation, purification thiab polymerization, tsim ib lub voj voog kaw thawj zaug ntawm "los ntawm xwm". Txawv ntawm cov yas ib txwm siv roj av, nws cov yam ntxwv rov ua dua tshiab yog qhov zoo tshaj plaws.

Raws li cov ntaub ntawv los ntawm Tuam Tshoj Plastics Processing Industry Association, tsim tau 1 tuj ntawm PLA tuaj yeem txo tau 2.1 tuj ntawm kev siv roj av thiab 3.2 tuj ntawm cov pa roj carbon. Qhov kev txo qis carbon no tau lees paub los ntawm cov lag luam thoob ntiaj teb, thiab nws tseem yog qhov laj thawj tseem ceeb vim li cas cov hom tshuaj yej mis nyuj hauv tsev coj nws ua lwm txoj hauv kev rau cov yas straws.

Cov Lus Cog Tseg: Kev Muab Cov Khoom Siv PLA Uas Muaj Kev Txhim Kho Tiag Tiag

Fua ntej, lawv muab kev paub zoo dua.Muaj coob tus neeg nco qab txog cov teeb meem nrog cov ntawv straws - nws yuav mos thiab tawv tom qab haus dej tau nees nkaum feeb. PLA straws feem ntau daws qhov teeb meem no. Lawv ruaj khov, tsis muaj saj, thiab zoo li cov yas ib txwm muaj, txhais tau tias "phooj ywg rau ib puag ncig" tsis tas yuav xav tias zoo li kev sib haum xeeb lawm.

Qhov thib ob, lawv muaj qhov kawg ntawm kev tshawb fawb meej.Nyob rau hauv qhov zoo tagnrhokev ua composting hauv kev lag luamtej yam kev mob, PLA txoj kev lwj yog qhov tseeb. Cov chaw tshwj xeeb muab cua sov tas mus li (55-70 ° C), av noo meej, thiab cov kab mob tshwj xeeb. Ntawm no,Cov pas nrig PLAfeem ntau yuav tawg ua cov pa roj carbon dioxide, dej, thiab biomass hauv 90 txog 180 hnub, ua tiav ib lub voj voog los ntawm cov nroj tsuag rov qab mus rau lub ntiaj teb.

Qhov tseem ceeb tshaj plaws, lawv hloov qhov chaw.Kev tsim ib tuj ntawm PLA tuaj yeem txuag tau li ob tuj roj av thiab txo cov pa roj carbon ntau dua peb tuj. Nws sawv cev rau qhov tseem ceeb: los ntawm kev khawb cov pob zeb qub mus rau kev siv cov nroj tsuag uas rov ua dua tshiab txhua xyoo.

Cov Ciam Teb Siv: Tsis Yog "Yuav Poob Tau Thoob Ntiaj Teb", Xav Tau Kev Hloov Kho Qhov Chaw

Qhov teeb meem nyob ntawm cov "xwm txheej zoo tshaj plaws."

Feem ntau cov kev nkag siab yuam kev txog PLA yog los ntawm kev sib npaug ntawm "biodegradable" thiab "degradable hauv txhua qhov chaw ib puag ncig". Nws qhov hu ua "qhov tsis zoo" yog qhov txwv ntawm qhov chaw:

Hais txog qhov kub thiab txias, PLA qhov kub hloov pauv iav yog li 50 ℃, yooj yim mos thiab deforming thaum tshaj qhov kub no, tsuas yog haum rau cov dej haus txias. Cov qauv tiv taus kub siab xav tau cov khoom hloov kho, txo qhov ua tau zoo ntawm kev puas tsuaj los ntawm 10% -30%. Hais txog ib puag ncig, nws qhov kev puas tsuaj nyob ntawm cov nroj tsuag tshwj xeeb hauv kev ua composting kev lag luam, nrog rau lub voj voog puas tsuaj ntau tshaj 50 xyoo hauv av kub ib txwm, thiab tsuas yog ob peb lub nroog hauv tsev muaj cov chaw kho mob loj. Hais txog tus nqi, tus nqi tam sim no ntawm PLA straws yog 0.08-0.1 yuan, 3-5 npaug ntawm cov yas ib txwm muaj, thiab tus nqi yuav poob ntau dua 30% tom qab nthuav dav peev xwm hauv xyoo 2026.

Ib Lub Zeem Muag Sib Npaug: Dab Tsi Yog PLA Straws Thiab Tsis Yog

PCov straws LA sawv cev rau ib qho thev naus laus zis hloov pauv muaj txiaj ntsig, tab sis lawv tsis yog lub mos txwv nyiaj. Lawv yog tus yuam sij uas tsuas yog ua haujlwm yog tias nws haum rau lub xauv - lub kaw lus ua cov khib nyiab sib xws. Rau Cov Neeg Siv Khoom: Kho lawv zoo li cov kwj deg pov tseg tshwj xeeb. Nrhiav daim ntawv pov thawj compostable ntseeg tau (xws li BPI) thiab ua raws li cov lus qhia hauv zos rau kev pov tseg rau hauv cov khib nyiab zaub mov lossis cov thoob khib nyiab ntsuab uas xa mus rau cov chaw lag luam.

Rau Kev Lag Luam: Lawv hais tias kev tsim kho tshiab ntawm cov khoom siv xwb tsis txaus. Cov kev daws teeb meem dav dav xav tau kev hloov pauv thoob plaws: kev tsim khoom zoo dua, kev qhia rau cov neeg siv khoom, thiab, qhov tseem ceeb, kev nqis peev hauv cov khoom siv composting.

Ib Kauj Ruam Tseem Ceeb Hauv Kev Hloov Pauv Ib Puag Ncig

PLA tsis yog ib qho kev daws teeb meem ib puag ncig zoo tshaj plaws, tab sis nws rhuav tshem qhov kev paub tias "kev tiv thaiv ib puag ncig yuav tsum tso tseg kev paub dhau los" thiab muab txoj hauv kev rau kev hloov pauv yas. Los ntawm kev nrov ntawm PLA straws, kev lag luam noj mov hauv tsev txo cov khib nyiab yas los ntawm ntau dua 120,000 tons txhua xyoo, sau cov kev paub dhau los rau kev hloov pauv ntawm lwm pawg. Nrog kev txhim kho ntawm thev naus laus zis thiab cov chaw, PLA yuav txuas ntxiv txhawb kev hloov pauv ib puag ncig, ua haujlwm ua tus choj tseem ceeb ntawm cov ntaub ntawv ntsuab tam sim no thiab yav tom ntej.
