Ingabe Pla Biodegradable?
•I-Polylactic acid, eyaziwa nangokuthi PLA, ibilokhu ikhona iminyaka eminingi. Kodwa-ke, abakhiqizi abakhulu be-PLA basanda kungena emakethe ngemuva kokuthola imali ezinkampanini ezinkulu ezimisele ukufaka esikhundleni sokwenziwa kwepulasitiki. Ngakho-ke, ingabe yi-PLA biodegradable?
•Ngenkathi impendulo ingeyona elula, sanquma ukunikeza incazelo futhi sincome ukufundwa okuthe xaxa kulabo abanentshisekelo. I-PLA akuyona into engathandeki, kepha iyancipha. Ama-enzyme angahle aphule i-PLA akuvamile ukutholakala emvelweni. I-Proteinase K yi-enzyme ethinta ukucekelwa phansi kwe-pla nge-hydrolysis. Abaphenyi abanjengoWilliams ngonyaka we-1981 kanti uTsuji noMiyauchi ngo-2001 bahlola ukuthi i-PLA iyi-biodegradable. Imiphumela yabo kuxoxwe ngayo encwadini ye-biomideli Science: Isingeniso sezinto zokwelashwa futhi wethulwa emhlanganweni we-European BioMadium Society. Ngokusho kwale mithombo, i-PLA ilawulwa ngokuyinhloko yi-hydrolysis, ezimele kunoma yimuphi ama-ejenti we-biologic. Ngenkathi abantu abaningi bangacabanga ukuthi i-PLA iyi-biodegradable, kubalulekile ukukubona lokhu.
•Eqinisweni, i-hydrolysis ye-pla nge-proteinase K ayivamile kangangokuba ayibalulekile ukuthi kuxoxwe ngokuqhubekayo ku-biomodium science. Siyethemba ukuthi lokhu kucacisa izingqinamba ezizungeze i-Pla BiodeGreatibilibility futhi sizoqhubeka nemizamo yethu yokuhlinzeka ngezisombululo ezinhle kakhulu zezondla zepulasitiki ezinobungane nezemvelo.
In isiphetho:
I-PLA yipulasitiki esetshenziswa kakhulu ezintweni zansuku zonke ezifana nezikhwama nezinkomishi ezilahlayo. Kodwa-ke, kungangcolisa kuphela ekuhlolweni kwezimboni noma ezindaweni zokugaya i-anaerobic, okwenza ukonakaliswa ezindaweni ezijwayelekile zemvelo zinselele. Ucwaningo luqinisekisile ukuthi i-PLA ilimaza kancane emvelweni yasolwandle.
