Ngaba i-PLA Biodegradable?
•I-Polylactic acid, ekwabizwa ngokuba yi-PLA, ikhona iminyaka emininzi.Nangona kunjalo, abavelisi abakhulu be-PLA basandula kungena kwimarike emva kokuba befumene inkxaso-mali kwiinkampani ezinkulu ezinomdla wokutshintsha iiplastiki zokwenziwa.Ke, ngaba i-PLA iyabola?
•Ngelixa impendulo ingekho lula, sigqibe kwelokuba sinikeze ingcaciso kwaye sicebise ukufunda ngakumbi kwabo banomdla.I-PLA ayiboli, kodwa yonakala.Ii-Enzymes ezinokwaphula i-PLA azifane zifumaneke kwindawo esingqongileyo.Iproteinase K yi-enzyme eyenza ukuthotywa kwe-PLA nge-hydrolysis.Abaphandi abanjengoWilliams ngo-1981 kunye noTsuji kunye noMiyauchi kwi-2001 bahlolisise umba wokuba i-PLA i-biodegradable.Iziphumo zabo zixutyushwa kwincwadi ethi Biomaterials Science: An Introduction to Medical Materials kwaye iboniswe kwintlanganiso ye-European Biomaterials Society.Ngokwale mithombo, i-PLA ilawulwa ngokukodwa nge-hydrolysis, ezimeleyo kuyo nayiphi na i-biologic agents.Ngelixa abantu abaninzi benokucinga ukuba i-PLA iyabola, kubalulekile ukuyiqonda le nto.
•Enyanisweni, i-hydrolysis ye-PLA yi-proteinase K inqabile kangangokuba ayibalulekanga ngokwaneleyo ukuba ixoxwe ngakumbi kwisayensi ye-biomaterial.Siyathemba ukuba oku kucacisa imiba ejikeleze ukonakaliswa kwezinto eziphilayo ze-PLA kwaye siya kuqhubeka neenzame zethu zokubonelela ngezona zisombululo zingcono kwiimfuno zakho zeplastiki ezinobungani bendalo kunye ne-biodegradable.
In isiphelo:
I-PLA yiplastiki enokubola esetyenziswa kakhulu kwizinto zemihla ngemihla ezifana neengxowa ezilahlwayo kunye neekomityi.Nangona kunjalo, inokuthotywa kuphela kwindawo yokwenziwa komgquba kwimizi-mveliso okanye i-anaerobic digestion, isenza ukonakaliswa kwindawo eqhelekileyo yendalo ibe ngumngeni.Uphononongo luqinisekisile ukuba i-PLA ithotywa kancinci kwindawo yaselwandle.
