Ngaba i-PLA iyabola?
•I-polylactic acid, ekwaziwa ngokuba yi-PLA, ibikho kangangeminyaka emininzi. Nangona kunjalo, abavelisi abakhulu be-PLA basandula ukungena kwimarike emva kokufumana inkxaso-mali kwiinkampani ezinkulu ezinomdla wokutshintsha iiplastiki ezenziweyo. Ngoko ke, ngaba i-PLA iyabola?
•Nangona impendulo ingekho lula, sigqibe ekubeni sinike ingcaciso size sicebise ukuba abo banomdla bafunde ngakumbi. I-PLA ayiboli, kodwa iyabola. Ii-enzymes ezinokubolisa i-PLA azifumaneki rhoqo kwindawo esingqongileyo. I-Proteinase K yi-enzyme ekhuthaza ukubola kwe-PLA nge-hydrolysis. Abaphandi abafana noWilliams ngo-1981 kunye noTsuji kunye noMiyauchi ngo-2001 baphonononge umba wokuba i-PLA iyabola na. Iziphumo zabo zixutyushwa kwincwadi ethi Biomaterials Science: An Introduction to Medical Materials kwaye zavezwa kwintlanganiso ye-European Biomaterials Society. Ngokwale mithombo, i-PLA ilawulwa ngokuyintloko yi-hydrolysis, ngaphandle kwe-arhente zebhayoloji. Nangona 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 yezinto eziphilayo. Siyathemba ukuba oku kuyayicacisa imiba ejikeleze i-PLA biodegradability kwaye siza kuqhubeka nemizamo yethu yokubonelela ngezisombululo ezilungileyo kwiimfuno zakho zeplastiki ezinobuhlobo nokusingqongileyo kunye ne-biodegradable.
Iisiphelo:
I-PLA yiplastiki ebolayo esetyenziswa kakhulu kwizinto zemihla ngemihla ezifana neengxowa kunye neekomityi ezilahlwayo. Nangona kunjalo, inokonakala kuphela kwiindawo zokwenza umgquba kwimizi-mveliso okanye kwiindawo zokugaya ukutya okungena-aerobic, nto leyo eyenza ukonakala kwiindawo zendalo eziqhelekileyo kube nzima. Izifundo ziqinisekisile ukuba i-PLA yonakala kancinci kwindawo yolwandle.
