Awọn ẹya ara ẹrọ ti PLA
1.Biodegradability
Ti a ṣe afiwe pẹlu awọn pilasitik ibile, polylactic acid le dinku si CO2 ati H2O nipasẹ awọn microorganisms ati ina.Awọn ọja ibajẹ iti kii ṣe majele ati laiseniyan ati pe kii yoo ba agbegbe jẹ.Awọn monomer fun producing polylactic, eyi ti o le wa ni fermented nipa ogbin bi alikama iresi ati suga beet tabi ogbin iru awọn ọja.Nitorina, awọn aise ohun elo fun producing polylactic acid jẹ sọdọtun.Polylactic acid gẹgẹbi awọn ohun elo biodegradable ti n yọ jade jẹ lilo pupọ.
2. Bio-ibaramu ati Absorb-agbara
Polylactic acid le jẹ hydrolyzed nipasẹ acid tabi henensiamu lati ṣe agbekalẹ lactic acid ninu ara eniyan.Gẹgẹbi metabolite ti awọn sẹẹli, polylactic acid le jẹ iṣelọpọ siwaju sii nipasẹ awọn enzymu ninu ara, lati ṣe agbekalẹ CO2 ati H2O.Nitorinaa, polylactic acid kii ṣe majele ati laiseniyan si ara eniyan pẹlupẹlu o ni ibamu bio-ibaramu ati agbara bio-absorb, Polylactic acid jẹ ifọwọsi nipasẹ Ile-iṣẹ Ounje ati Oògùn AMẸRIKA ti o le ṣee lo bi ohun elo bio-fun gbingbin ni eniyan.
3. Ti ara Machinable
