Dab tsi yog lub hnab biodegradable
Lub hnab biodegradable yog ib hom hnab yas uas tuaj yeem tawg ua cov sib txuas me me thiab nws thiaj li decomposed rau hauv tej yam ntuj tso xws li dej, carbon dioxide, thiab biomass. Cov hnab no feem ntau yog tsim los ntawm biodegradable polymers muab los ntawm cov khoom siv cog xws li cov hmoov txhuv nplej siab lossis cellulose. Piv nrog rau cov hnab yas ib txwm siv, cov hnab biodegradable tuaj yeem tawg sai dua thiab muaj kev cuam tshuam me me rau kev ua qias tuaj ib puag ncig. Biodegradable hnab feem ntau yog siv los hloov cov hnab yas ib txwm siv los txo lawv qhov cuam tshuam rau ib puag ncig.
Cov ntaub ntawv ntawmdegradable yas ntim hnabsuav nrog:
1. PLA (polylactic acid): Nws yog tsim los ntawm cov khoom siv hmoov txhuv nplej siab, uas yog biodegradable thiab tuaj yeem degraded ib txwm nyob hauv av.
2. PBAT (polybutylene succinate/butanediol glutarate): yog ua los ntawm biodegradable polyester, uas tuaj yeem decomposed los ntawm cov kab mob los tsim carbon dioxide, dej thiab biomass tom qab degradation.
3. PHA (polyhydroxyalkanoate): ib yam khoom polyester synthesized los ntawm cov kab mob los ntawm cov txheej txheem fermentation, uas muaj biodegradability zoo thiab tuaj yeem degraded nyob rau hauv ib puag ncig ntuj.
4. PCL (Polycaprolactone): Ua los ntawm fossil fuels xws li roj av, nws tuaj yeem degraded nyob rau hauv ib puag ncig ntuj, thiab nws tus nqi decomposition tuaj yeem nrawm los ntawm lub cev lossis tshuaj.
Nws yuav tsum tau muab sau tseg tias txawm hais tias cov ntaub ntawv no muaj ib tug tej yam degree ntawm biodegradability, nws tsis tau txhais hais tias lawv yuav decomposed sai nyob rau hauv tag nrho cov mob, yog li kev siv thiab pov tseg ntawm cov ntim cov ntaub ntawv tseem yuav tsum tau ceev faj thiab scientific tsim nyog.
