Degradable ntim hnab, qhov cuam tshuam yog degradable, tab sis degradable ntim tau muab faib ua "degradable" thiab "tag nrho degradable" ob yam.
Lub hnab yas biodegradable yog ua los ntawm cov nyom nyom thiab lwm yam zoo rau tib neeg lub cev thiab ib puag ncig, sib txawv ntawm peb cov khoom siv hluavtaws, tom qab pov tseg, nyob rau hauv qhov kev ua ntawm ib puag ncig lom neeg, tuaj yeem decomposed los ntawm nws tus kheej, tsis hais rau tib neeg lossis ib puag ncig. yog harmless, belongs rau lub ntim ntsuab.Lub hnab yas degradable yog ib hom ntawm cov khoom siv pov tseg uas tuaj yeem degraded thiab yooj yim degraded.
Cov hnab yas degradable tuaj yeem muab faib ua ob hom los ntawm qhov sib txawv ntawm cov khoom siv raw thiab decomposition yam:
• Ib lub hnab yas feem ntau yog ua los ntawm cov yas polyethylene, tov nrog cov hmoov txhuv nplej siab thiab lwm cov tshuaj lom neeg degradable, los yog lub hnab yas biodegradable.Hom hnab yas no decomposes tsuas yog los ntawm kev ua ntawm cov kab mob.
• Lwm hom yog tsim los ntawm polyethylene yas, tov nrog ntxhia hmoov xws li lub teeb desorption tus neeg saib xyuas thiab calcium carbonate, uas tseem hu ua lub teeb desorption hnab yas.Lub hnab yas zoo li no tawg hauv qab qhov kev txiav txim ntawm lub hnub.
Lub hnab degradable tiav txhais tau hais tias tag nrho cov hnab yas yog degraded rau hauv dej thiab carbon dioxide.Lub hauv paus tseem ceeb ntawm cov khoom siv degradable no yog ua tiav los ntawm pob kws, cassava thiab lwm yam ntaub ntawv rau hauv lactic acid, los yog PLA.Poly Lactic Acid (PLA) yog ib yam tshiab ntawm cov khoom siv roj ntsha thiab cov khoom siv rov ua dua tshiab biodegradable.Cov khoom siv hmoov txhuv nplej siab yog saccharified kom tau cov piam thaj, thiab tom qab ntawd cov piam thaj thiab qee hom yog fermented los tsim cov purity lactic acid, thiab tom qab ntawd PLA nrog qee qhov hnyav molecular yog tsim los ntawm cov txheej txheem tshuaj synthesis.Nws muaj biodegradability zoo.Tom qab siv, nws tuaj yeem degraded los ntawm cov kab mob hauv cov kab mob hauv cov xwm txheej tshwj xeeb, thiab thaum kawg tsim cov pa roj carbon dioxide thiab dej.Nws tsis ua phem rau ib puag ncig, uas muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab yog ib puag ncig-phooj ywg rau cov neeg ua haujlwm.
