Ingabe i-PLA Ingabola?
•I-polylactic acid, eyaziwa nangokuthi i-PLA, ibilokhu ikhona iminyaka eminingi. Kodwa-ke, abakhiqizi abakhulu be-PLA basanda kungena emakethe ngemuva kokuthola uxhaso ezinkampanini ezinkulu ezifisa ukufaka esikhundleni sepulasitiki yokwenziwa. Ngakho-ke, ingabe i-PLA iyabola?
•Nakuba impendulo ingekho lula, sinqume ukunikeza incazelo futhi sincoma ukuthi siqhubeke nokufundwa kulabo abanentshisekelo. I-PLA ayiboli, kodwa iyabola. Ama-enzyme angabhidliza i-PLA awatholakali kakhulu endaweni ezungezile. I-Proteinase K iyi-enzyme ekhuthaza ukubola kwe-PLA nge-hydrolysis. Abacwaningi abanjengoWilliams ngo-1981 kanye noTsuji noMiyauchi ngo-2001 bahlola udaba lokuthi i-PLA iyabola yini. Imiphumela yabo ixoxwa encwadini ethi Biomaterials Science: An Introduction to Medical Materials futhi yethulwa emhlanganweni we-European Biomaterials Society. Ngokusho kwale mithombo, i-PLA ilawulwa kakhulu yi-hydrolysis, ngaphandle kwanoma yiziphi izinto eziphilayo. Ngenkathi abantu abaningi bengase bacabange ukuthi i-PLA iyabola, kubalulekile ukuqaphela lokhu.
•Eqinisweni, i-hydrolysis ye-PLA yi-proteinase K ayivamile kangangokuthi ayibalulekile ngokwanele ukuba ixoxwe kabanzi kwisayensi yezinto eziphilayo. Sithemba ukuthi lokhu kuzocacisa izinkinga eziphathelene nokubola kwe-PLA futhi sizoqhubeka nemizamo yethu yokuhlinzeka ngezixazululo ezinhle kakhulu zezidingo zakho zepulasitiki ezinobungani nemvelo kanye nokubola.
Iisiphetho:
I-PLA iyipulasitiki ebolayo esetshenziswa kakhulu ezintweni zansuku zonke njengezikhwama nezinkomishi ezilahlwayo. Kodwa-ke, ingonakala kuphela ezindaweni zokukhiqiza umquba noma zokugaya ukudla okungena-aerobic, okwenza ukuwohloka ezindaweni zemvelo ezivamile kube nzima. Izifundo ziqinisekisile ukuthi i-PLA yonakala kancane endaweni yasolwandle.
