Is PLA Biodegradable?
•Polylactic acid, inozivikanwawo sePLA, yave iripo kwemakore mazhinji.Nekudaro, vagadziri vakuru vePLA vachangobva kupinda mumusika mushure mekuwana mari kubva kumakambani makuru anoda kutsiva mapurasitiki ekugadzira.Saka, PLA inogona kuparara here?
•Kunyange mhinduro isiri nyore, takasarudza kupa tsananguro uye nekukurudzira kuwedzera kuverenga kune vanofarira.PLA haina biodegradable, asi inoshatisa.Ma Enzymes anogona kuputsa PLA haawanzo kuwanikwa munzvimbo.Proteinase K is enzyme inokonzera kuparara kwePLA kuburikidza nehydrolysis.Vatsvagiri vakaita saWilliams muna 1981 naTsuji naMiyauchi muna 2001 vakaongorora nyaya yekuti PLA inoodza here.Mhedzisiro yavo inokurukurwa mubhuku rinonzi Biomaterials Science: An Introduction to Medical Materials uye yakaratidzwa pamusangano weEuropean Biomaterials Society.Zvinoenderana neaya masosi, PLA inodzorwa zvakanyanya nehydrolysis, yakazvimirira kune chero biologic agents.Nepo vanhu vazhinji vangafunga kuti PLA inoodza, zvakakosha kuti uzive izvi.
•Muchokwadi, hydrolysis yePLA neproteinase K haina kushomeka zvekuti haina kukosha zvakakwana kuti ikurukurwe mberi mune biomaterial sainzi.Tinovimba izvi zvinojekesa nyaya dzakatenderedza PLA biodegradability uye isu tichaenderera mberi nekuedza kwedu kupa mhinduro dzakanakisa dzezvakatipoteredza uye biodegradable zvepurasitiki zvaunoda.
In mhedziso:
PLA ipurasitiki inogona kuparara inoshandiswa zvakanyanya muzvinhu zvemazuva ese semabhegi anoraswa nemakapu.Nekudaro, inogona kungodzikisira muindasitiri composting kana anaerobic digestion nharaunda, zvichiita kushatisa munzvimbo dzakajairwa dzechisikigo zvinonetsa.Zvidzidzo zvakasimbisa kuti PLA inokanganisa zvishoma munzvimbo yegungwa.
