"Cov pa roj carbon tsawg" tau dhau los ua lub ntsiab lus tseem ceeb hauv lub sijhawm tshiab. Nyob rau hauv xyoo tas los no, kev tiv thaiv ib puag ncig ntsuab, kev txuag hluav taws xob, thiab kev txo qis emission tau maj mam nkag mus rau pej xeem lub zeem muag, thiab kuj tau dhau los ua ib qho kev tawm tswv yim tshiab thiab nrov hauv zej zog. Nyob rau hauv lub caij ntuj sov thiab cov pa roj carbon tsawg, kev siv cov khoom siv biodegradable yog suav tias yog lub cim tseem ceeb ntawm lub neej tsis tshua muaj roj carbon monoxide, thiab tau txais kev hwm thiab nthuav tawm.

Nrog rau kev nrawm nrawm ntawm lub neej, cov khoom siv pov tseg ua npuas ncauj yas noj su, hnab yas, chopsticks, khob dej thiab lwm yam khoom tau dhau los ua txhua yam hauv lub neej. Sib txawv ntawm daim ntawv, ntaub thiab lwm yam ntaub ntawv, cov khoom yas yog muab pov tseg nyob rau hauv cov xwm thiab nyuaj rau degraded. Thaum ua kom yooj yim rau tib neeg lub neej, kev siv ntau dhau tuaj yeem ua rau "dawb paug". Hauv cov ntsiab lus no, biodegradable biomaterials tau tshwm sim. Cov ntaub ntawv biodegradable yog cov khoom siv tshiab uas muaj txiaj ntsig zoo ntawm kev ua haujlwm ib puag ncig piv rau cov khoom siv yas pov tseg. Cov khoom tsim khoom siv biodegradable biomaterials raws li cov ntaub ntawv raw muaj qhov chaw ua lag luam loj thiab dhau los ua ib qho tseem ceeb ntawm cov qauv kev ua neej nyob qis qis.

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

PLA, kuj hu uapolylactic acidd, CAS Nr .: 26023-30-3yog cov hmoov txhuv nplej siab raw khoom uas yog fermented los tsim lactic acid, uas tom qab ntawd hloov mus rau hauv polylactic acid los ntawm cov tshuaj synthesis thiab muaj biodegradability zoo. Tom qab siv, nws tuaj yeem degraded tag nrho los ntawm cov kab mob hauv cov xwm txheej, thaum kawg tsim cov pa roj carbon dioxide thiab dej tsis muaj kuab paug ib puag ncig. Ib puag ncig zoo heev, thiab PLA tau lees paub tias yog ib puag ncig tus phooj ywg cov khoom uas muaj cov khoom lom neeg zoo heev.

Cov ntaub ntawv tseem ceeb ntawm PLA yog cov nroj tsuag txuas ntxiv dua tshiab, pob kws thiab lwm yam khoom ua liaj ua teb thiab sab nrauv, thiab PLA yog ib ceg tseem ceeb ntawm cov khoom siv biodegradable. PLA muaj cov yam ntxwv tshwj xeeb ntawm hardness thiab pob tshab. Nws muaj zog biocompatibility, dav siv ntau yam, muaj zog lub cev thiab txhua yam khoom, thiab ua tau raws li ntau yam kev siv. Nws tuaj yeem siv ntau txoj hauv kev rau kev tsim khoom loj, nrog rau cov kab mob tua kab mob ntawm 99.9%, ua rau nws cov khoom pheej yig tshaj plaws degradable.

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

PLA tsim los ntawmUnilong Kev Lag Luamyog qhov kawg ntawm txhua txhua polylactic acid "particle". Los ntawm kev xaiv nruj ntawm cov khoom siv zoo polylactic acid raw khoom, PLA polylactic acid yas thiab PLA polylactic acid fiber ntau yog siv los tsim kev noj qab haus huv, tawv nqaij zoo, zoo, thiab muaj zog tiv thaiv kab mob roj av raws li cov yas hloov. Nws cov khoom tseem ceeb suav nrog cov khaub ncaws hnav, khau thiab kaus mom, cov tais diav, khob thiab kettles, cov ntawv sau, cov khoom ua si, cov khoom siv hauv tsev, cov ris tsho hnav thiab ris, cov khoom siv hauv tsev, cov ntaub so qhuav thiab ntub dej, thiab lwm yam uas cuam tshuam nrog peb lub neej txhua hnub.

Qhov tshwm sim ntawmPLAtuaj yeem pab tib neeg kom nyob deb ntawm cov pa phem dawb, txo cov yas puas, thiab txhawb kev ua kom zoo tshaj plaws ntawm cov pa roj carbon monoxide thiab carbon neutrality. Lub hom phiaj ntawm Unilong Kev Lag Luam yog "ua raws li lub sijhawm ntawm lub sijhawm, coj txoj kev ua neej nyob ib puag ncig", txhawb nqa cov khoom lag luam biodegradable, ua rau tib neeg noj qab haus huv thiab ua neej nyob zoo, cia biodegradation nkag mus rau ntau txhiab tsev neeg, ua tus qauv tshiab ntawm ntsuab thiab qis-carbon lub neej, thiab nkag siab nkag mus rau lub neej qis-carbon.
