"Kev nyob uas tsis muaj carbon ntau" tau dhau los ua ib qho tseem ceeb hauv lub caij nyoog tshiab. Nyob rau xyoo tas los no, kev tiv thaiv ib puag ncig ntsuab, kev txuag hluav taws xob, thiab kev txo qis pa phem tau maj mam nkag mus rau hauv pej xeem lub zeem muag, thiab kuj tau dhau los ua ib qho kev hloov pauv tshiab uas tau txhawb nqa thiab nrov zuj zus hauv zej zog. Hauv lub caij nyoog ntsuab thiab qis carbon, kev siv cov khoom siv biodegradable yog suav tias yog ib lub cim tseem ceeb ntawm lub neej qis carbon, thiab tau txais kev hwm thiab nthuav dav.

Nrog rau kev nce qib ntawm lub neej, cov thawv ntim pluas su yas ua npuas dej pov tseg, hnab yas, chopsticks, khob dej thiab lwm yam khoom tau dhau los ua qhov chaw nyob hauv lub neej. Txawv ntawm ntawv, ntaub thiab lwm yam khoom siv, cov khoom yas raug pov tseg rau hauv qhov xwm txheej thiab nyuaj rau lwj. Thaum coj kev yooj yim rau tib neeg lub neej, kev siv ntau dhau kuj tuaj yeem ua rau "kev ua qias tuaj dawb". Hauv cov ntsiab lus no, cov khoom siv biodegradable biodegradable tau tshwm sim. Cov khoom siv biodegradable yog cov khoom siv tshiab uas muaj qhov zoo tseem ceeb hauv kev ua tau zoo ib puag ncig piv rau cov khoom siv yas pov tseg ib txwm muaj. Cov khoom tsim los ntawm kev siv cov khoom siv biodegradable ua cov khoom siv raw muaj qhov chaw ua lag luam loj heev thiab dhau los ua tus neeg nqa khoom tseem ceeb ntawm lub tswv yim kev ua neej tsis muaj carbon tsawg.

Muaj ntau hom khoom siv biodegradable, suav nrogPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, thiab lwm yam. Niaj hnub no peb yuav tsom mus rau cov khoom siv biodegradable PLA.

PLA, kuj hu uapolylactic acid, CAS 26023-30-3yog cov khoom siv hmoov txhuv nplej siab uas tau fermented los tsim cov lactic acid, uas tom qab ntawd hloov mus ua polylactic acid los ntawm kev tsim tshuaj lom neeg thiab muaj biodegradability zoo. Tom qab siv, nws tuaj yeem raug degraded tag nrho los ntawm cov kab mob me me hauv qhov xwm txheej, thaum kawg tsim cov pa roj carbon dioxide thiab dej yam tsis ua rau ib puag ncig puas tsuaj. Ib puag ncig zoo heev, thiab PLA tau lees paub tias yog cov khoom siv zoo rau ib puag ncig nrog cov khoom zoo heev.

Cov khoom siv tseem ceeb ntawm PLA yog cov nroj tsuag rov ua dua tshiab, pob kws thiab lwm yam khoom ua liaj ua teb thiab cov khoom siv sab nraud, thiab PLA yog ib ceg tseem ceeb ntawm cov khoom siv biodegradable tshiab. PLA muaj cov yam ntxwv tshwj xeeb hauv kev tawv thiab pob tshab. Nws muaj kev sib raug zoo ntawm biocompatibility, ntau yam kev siv, muaj zog lub cev thiab lub cev, thiab ua tau raws li ntau yam kev siv. Nws tuaj yeem siv rau ntau txoj hauv kev rau kev tsim khoom loj, nrog rau tus nqi tua kab mob ntawm 99.9%, ua rau nws yog cov khoom siv degradable zoo tshaj plaws.

Polylactic acid (PLA)yog ib yam khoom tshiab uas zoo rau ib puag ncig thiab ntsuab biodegradable uas tsim los ntawm lactic acid ua raw khoom; Nyob rau hauv xyoo tas los no, PLA tau siv rau cov khoom thiab cov teb xws li straws, tableware, cov ntaub ntawv ntim zaj duab xis, fibers, ntaub, 3D printing cov ntaub ntawv, thiab lwm yam. PLA kuj muaj peev xwm loj hlob zoo hauv cov teb xws li cov khoom siv kho mob, cov khoom siv tsheb, kev ua liaj ua teb, kev cog ntoo, thiab kev tiv thaiv ib puag ncig.

Cov PLA tsim los ntawmKev Lag Luam Unilongyog qhov kawg ntawm txhua yam "polylactic acid" me me. Los ntawm kev xaiv cov khoom siv polylactic acid zoo, PLA polylactic acid yas thiab PLA polylactic acid fiber yog siv los tsim cov khoom noj qab haus huv, zoo rau daim tawv nqaij, zoo, thiab muaj zog tiv thaiv kab mob. Nws cov khoom tseem ceeb suav nrog cov khaub ncaws niaj hnub, khau thiab lub kaus mom, cov khoom siv rooj tog, khob thiab lub lauj kaub, cov ntawv sau, cov khoom ua si, cov ntaub hauv tsev, cov khaub ncaws thiab ris tsho, cov khoom siv hauv tsev, cov ntaub so qhuav thiab ntub, thiab lwm yam uas cuam tshuam nrog peb lub neej txhua hnub.

Qhov tshwm sim ntawmPLAtuaj yeem pab tib neeg nyob deb ntawm cov pa phem dawb, txo cov yas puas tsuaj, thiab txhawb kom muaj kev paub zoo txog cov pa roj carbon thiab cov pa roj carbon neutrality. Lub hom phiaj ntawm Unilong Industry yog "ua raws li lub sijhawm, ua lub neej zoo rau ib puag ncig", txhawb nqa cov khoom biodegradable, ua rau tib neeg noj zaub mov zoo dua thiab nyob lub neej noj qab haus huv dua, cia biodegradation nkag mus rau ntau txhiab tsev neeg, ua tus qauv tshiab ntawm lub neej ntsuab thiab qis carbon, thiab nkag mus rau hauv lub neej qis carbon.
