Ingabe i-PLA Biodegradable?
•I-Polylactic acid, eyaziwa nangokuthi i-PLA, isineminyaka eminingi ikhona.Kodwa-ke, abakhiqizi abakhulu be-PLA basanda kungena emakethe ngemuva kokuthola uxhaso ezinkampanini ezinkulu ezizimisele ngokushintsha amapulasitiki okwenziwa.Ngakho-ke, ingabe i-PLA iyabola?
•Yize impendulo ingelula, sinqume ukunikeza incazelo futhi sincoma ukuthi kuqhutshekwe nokufunda kulabo abanentshisekelo.I-PLA ayiboli, kodwa yonakala.Ama-enzyme angakwazi ukudiliza i-PLA awavamile ukutholakala endaweni ezungezile.I-Proteinase K iyi-enzyme eyenza ukuwohloka kwe-PLA nge-hydrolysis.Abacwaningi abanjengoWilliams ngo-1981 kanye noTsuji noMiyauchi ngo-2001 bahlola udaba lokuthi i-PLA iyabola yini.Imiphumela yabo kuxoxwa ngayo encwadini ethi Biomaterials Science: An Introduction to Medical Materials futhi yethulwa emhlanganweni we-European Biomaterials Society.Ngokwale mithombo, i-PLA ilawulwa ngokuyinhloko nge-hydrolysis, ngaphandle kwanoma yimaphi ama-biologic agents.Nakuba abantu abaningi bengase bacabange ukuthi i-PLA iyakwazi ukubola, kubalulekile ukukuqaphela lokhu.
•Eqinisweni, i-hydrolysis ye-PLA nge-proteinase K ayivamile kangangokuthi ayibalulekile ngokwanele ukuba kuxoxwe ngayo kusayensi ye-biomaterial.Sithemba ukuthi lokhu kuzocacisa izingqinamba eziphathelene nokubola kwe-PLA futhi sizoqhubeka nemizamo yethu yokuhlinzeka ngezixazululo ezingcono kakhulu zezidingo zakho zepulasitiki ezingangcolisi imvelo nezibolayo.
In isiphetho:
I-PLA iyipulasitiki ebolayo esetshenziswa kakhulu ezintweni zansuku zonke njengezikhwama nezinkomishi ezilahlwayo.Kodwa-ke, kungonakalisa kuphela endaweni yokwenza umquba wezimboni noma endaweni yokugaya ukudla kwe-anaerobic, okwenza ukuwohloka kwezindawo zemvelo kube inselele.Ucwaningo luye lwaqinisekisa ukuthi i-PLA yehlisa isithunzi kancane endaweni yasolwandle.
