Taw qhia txog ntawm anti-xeb peb-seem hnab khoom

Biodegradable hnab yas yog cov khoom siv roj hmab uas tuaj yeem ua kom muaj kev phom sij (xws li cov kev ua kom muaj zog (xws li cov teeb meem microbial, lub teeb lossis dej sib cais):

1. Cov ntaub ntawv tseem ceeb thiab cov yam ntxwv ntawm biodegradable plastics

Cov khoom siv tseem ceeb ntawm biodegradable plastics
Cov ntaub ntawv txiag polymer: cov hmoov txhuv nplej siab (pob kws, thiab cov ntoo khaub noom (cov khaub noom cellulose)
Cov khoom siv hluavtaws biodegradable:
Polylactic Acid (TA): Ua los ntawm cov nplej zom ua ke, tsawg dua lossis sib npaug nrog pbat los txhim kho cov tawv nqaij kom txhim kho kev ua kom nruj.
Pbat / PBS: roj av-lossis hluav taws xob sib xyaw ua ke, hloov tau thiab feem ntau siv nyob rau hauv cov ntaub ntawv sib xyaw.
Polyhydroxy Fatty Acid Ester (Phay): ncaj qha synthesized los ntawm cov kab mob hauv qab, tsis yeem nyob hauv hiav txwv thiab av, thiab tus nqi siab .
Kev ua kom zoo ntawm cov khoom ntawm biodegradable plastics
Los ntawm blending pla thiab pbat (feem ntau yog nyob rau hauv ib tug sib piv ntawm 7: 3), siv rau hauv tus account hardness thiab yooj yim dua.
Cov ntaub ntawv hmoov txhuv nplej siab yuav tsum tau ntxiv nrog cov yas ua kom tau yooj yim los txhim kho kev ruaj khov thiab zam qhov kev tsim ntawm microplastics {}}

Kev tsis pom zoo mechanism thiab ib puag ncig yuav tsum muaj ntawm biodegradable plastics

Lub hauv paus ntsiab lus ntawm biodegradation ntawm plastics

Microorganisms secreet esterase thiab lwm yam "molecular txiab" los txiav cov molecular, thiab maj decomepose rau hauv dej, carbon dioxide thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic ntsev thiab inorganic
Cov Kev Tsim Nyog Tsim Nyog: Nws xav tau ib qho chaw sib sau ua ke (cov huab cua kub thiab av noo + cov micradganism nplua nuj), thiab qhov kev nplua nuj qeeb hauv ib puag ncig ntuj.

Kev ua raws li kev sib tw thiab cov khoom lag luam ntawm biodegradable plastics
