Dab tsi ntawm Environmentally Friendly Thiab Degradable Materials Muaj?

Nrog rau txoj kev loj hlob ntawm tib neeg lub neej, cov khoom yas tau dhau los ua ib feem tseem ceeb ntawm lub neej. Txawm li cas los xij, cov khoom yas tsoos yog qhov nyuaj rau degrade thiab ua rau muaj kuab paug loj rau lub ntiaj teb ib puag ncig. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb tau nquag tsim cov khoom siv degradable, qhib tshooj tshiab rau kev tiv thaiv ib puag ncig. Kab lus no yuav qhia txog ntau yam khoom tseem ceeb uas degradable, lawv cov yam ntxwv thiab kev siv.

 

1. Polylactic acid (PLA)

Polylactic acid yog cov khoom siv biodegradable uas ua los ntawm cov hmoov txhuv nplej siab uas tau muab rho tawm los ntawm cov chaw cog qoob loo (xws li pob kws). PLA muaj biocompatibility zoo thiab biodegradability thiab tuaj yeem decomposed rau hauv dej thiab carbon dioxide los ntawm cov kab mob hauv cov xwm txheej. PLA yog dav siv nyob rau hauv ntim, fiber ntau sportswear, ua liaj ua teb mulch zaj duab xis, 3D luam ntawv thiab lwm yam teb. Tshwj xeeb tshaj yog nyob rau hauv kev ntim khoom noj, PLA tableware, khob, tais thiab lwm yam khoom tau dhau los ua neeg nyiam.

 

2. Polyhydroxyalkanoate (PHA)

Polyhydroxyalkanoates yog aliphatic copolyesters nrog cov qauv sib txawv ua ke los ntawm cov kab mob los ntawm fermentation ntawm ntau qhov chaw carbon. PHA muaj cov khoom siv roj zoo thiab lub siab melting point, thiab tuaj yeem siv los ua cov khoom siv raw rau cov ntaub ntawv pov tseg, cov ntaub tsis-woven thiab lwm yam khoom. Piv nrog PLA, PHA muaj biocompatibility zoo dua thiab tuaj yeem siv rau hauv cov khoom siv kho mob, cov neeg nqa tshuaj thiab lwm yam haujlwm.

 

3. Poly ε-caprolactone (PCL)

Polyε-caprolactone yog ib qho qis melting point polymer tau los ntawm lub nplhaib-qhib polymerization ntawm ε-caprolactone. Lub melting point ntawm PCL tsuas yog 62 degree, thiab nws muaj biodegradability zoo, biocompatibility thiab non-toxicity. Yog li, PCL tuaj yeem siv rau hauv cov tshuaj tswj kev tso tawm, thiab tuaj yeem ua rau cov khoom siv kho mob pob txha kho, phais phais, thiab lwm yam. Tsis tas li ntawd, PCL kuj tuaj yeem siv los ua ib puag ncig tus phooj ywg plasticizer rau thermoplastic resins, ntim cov khoom ua si thiab tshuaj pleev ib ce, thiab lwm teb.

 

4. Polyester PBS / PBSA

Polyester PBS siv aliphatic succinic acid thiab butylene glycol ua cov ntaub ntawv tseem ceeb. Nws kuj tseem tuaj yeem tsim los ntawm cov khoom siv roj ntsha fermentation ntawm cov khoom siv qoob loo rov ua dua tshiab xws li cov hmoov txhuv nplej siab, cellulose, thiab qabzib. PBS yog siv rau hauv catering, ntim, tshuaj pleev ib ce fwj, tshuaj fwj, cov khoom siv kho mob pov tseg, cov yeeb yaj kiab ua liaj ua teb, tshuaj tua kab thiab chiv cov ntaub ntawv tso tawm, biomedical polymer cov ntaub ntawv thiab lwm yam. PBSA yog cov khoom siv hloov kho ntawm PBS nrog zoo thermal stability thiab mechanical zog, thiab yog dav siv nyob rau hauv lub tshav pob ntawm 3D printing.

5. Daim ntawv thov kev cia siab

Nrog rau kev txhim kho ntawm ib puag ncig kev paub thiab kev txhawb nqa cov cai, kev thov kev cia siab ntawm cov ntaub ntawv degradable tau dhau los ua ntau thiab dav. Nyob rau hauv lub neej yav tom ntej, cov ntaub ntawv degradable yuav maj mam hloov cov khoom siv yas thiab txo cov pa phem ib puag ncig. Nyob rau tib lub sijhawm, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov kws tshawb fawb yuav txuas ntxiv txhim kho cov ntaub ntawv degradable nrog kev ua tau zoo dua thiab tus nqi qis los txhawb kev txhim kho txuas ntxiv ntawm kev tiv thaiv ib puag ncig. Tsis tas li ntawd, kev siv cov khoom siv degradable hauv kev kho mob, kev ua liaj ua teb, kev lag luam thiab lwm yam kev lag luam tseem yuav nthuav dav ntxiv, ua kom yooj yim dua thiab kev tiv thaiv ib puag ncig rau tib neeg lub neej.

Saum toj no:

Raws li ib tug pioneer nyob rau hauv lub tshiab era ntawm kev tiv thaiv ib puag ncig, degradable cov ntaub ntawv tau qhia muaj zog daim ntawv thov muaj peev xwm nyob rau hauv ntau yam teb. Cov ntaub ntawv xws li polylactic acid, polyhydroxyalkanoate, polyε-caprolactone thiab polyester PBS / PBSA txhua tus muaj cov yam ntxwv tshwj xeeb thiab siv, thiab ua ke lawv pab daws teeb meem ib puag ncig. Cia peb koom tes zoo siab tos txais lub sijhawm tshiab ntawm kev tiv thaiv ib puag ncig thiab tsim kom muaj lub neej yav tom ntej zoo ua ke!
