Raws li cov khoom siv raw ntawm biodegradable plastics, muaj ob hom Biodegradable Plastics: Bio raws li thiab petrochemical raws li. PBAT yog ib hom petrochemical raws li biodegradable plastics.
Los ntawm cov txiaj ntsig ntawm kev sim biodegradation, PBAT tuaj yeem degraded tag nrho nyob rau hauv ib txwm huab cua puag ncig thiab faus rau hauv av rau 5 lub hlis.
Yog tias PBAT nyob hauv dej hiav txwv, cov kab mob me me tau hloov mus rau qhov chaw ntsev siab nyob hauv dej hiav txwv. Thaum qhov kub thiab txias yog 25 ℃ ± 3 ℃, nws tuaj yeem degraded tag nrho hauv li 30-60 hnub.
PBAT biodegradable plastics tuaj yeem ua rau biodegraded nyob rau hauv composting tej yam kev mob, lwm yam kev mob xws li anaerobic digestion ntaus ntawv, thiab tej yam ntuj tso ib puag ncig xws li av thiab seawater.
Txawm li cas los xij, qhov xwm txheej tshwj xeeb degradation thiab lub sij hawm degradation ntawm PBAT muaj feem xyuam rau nws cov qauv tshuaj tshwj xeeb, cov qauv ntawm cov khoom lag luam thiab degradation ib puag ncig.
