Biodegradation feem ntau yog hais txog decomposition ntawm cov kab mob. Cov kab mob uas muaj nyob rau hauv cov xwm txheej decomposes yam tsis muaj kev cuam tshuam rau ib puag ncig. Lub degree ntawm degradation yog hu ua degradation index. Biodegradable cov ntaub ntawv xa mus rau cov ntaub ntawv uas tuaj yeem decomposed tag nrho rau hauv cov tebchaw uas tsis tshua muaj molecular los ntawm cov kab mob (xws li cov kab mob, fungi thiab algae, thiab lwm yam) nyob rau hauv qhov tsim nyog thiab ua kom pom qhov chaw ib puag ncig.
Cov cuab yeej / khoom siv
Polycaprolactone, polybutylene succinate, polylactic acid, polyhydroxyalkanoate, aliphatic aromatic copolyester
txoj kev / kauj ruam
1.Biodegradation feem ntau yog hais txog kev decomposition ntawm cov kab mob. Cov kab mob uas muaj nyob rau hauv cov xwm txheej decomposes yam tsis muaj kev cuam tshuam rau ib puag ncig. Lub degree ntawm degradation yog hu ua degradation index. Biodegradable cov ntaub ntawv xa mus rau cov ntaub ntawv uas tuaj yeem decomposed tag nrho rau hauv qis-molecular-yuag compounds los ntawm cov kab mob (xws li cov kab mob, fungi thiab algae, thiab lwm yam) nyob rau hauv tsim nyog thiab ua kom pom tseeb tej yam ntuj tso tej yam kev mob.
3. Sib tov cov khoom piv txwv nrog cov compost inoculum thiab muab tso rau hauv lub thawv composting. Nyob rau hauv tej yam kev mob ntawm cov pa oxygen, kub (58 ± 2C), thiab av noo ({3}} feem pua), ua composting txaus, thiab ntsuas qhov degradation ntawm cov khoom tom qab 45 hnub. Qhov kawg tso tawm ntawm CO2 (tuaj yeem txuas ntxiv mus rau 6 lub hlis), qhov sib piv ntawm qhov tseeb tso tawm ntawm CO2 rau nws qhov kev tso tawm siab tshaj plaws yog siv los sawv cev tus nqi biodegradation ntawm cov khoom.
