PLA, kuma aka sani da polylactic acid polymerized daga poly lactic acid.Polylactic acid yana da kyakkyawan biodegradability, dacewa da sha, ba mai guba ba ne, kayan polymer na roba .lts albarkatun kasa shine polylactic acid, wanda aka samo asali daga fermentation na sitaci, irin su com da rc.Hakanan za'a iya samun shi daga cellulose, datti na dafa abinci ko sharar kifi.
PLA yana da nau'i mai yawa na albarkatun kasa, kuma samfurori da aka yi daga gare ta za a iya yin takin kai tsaye ko ƙonawa, wanda zai iya biyan bukatun ci gaba mai dorewa. don aikace-aikacen sa mai yaduwa.
Bugu da kari, PLA yana da thermal-plasticity kuma ana iya amfani da shi a fannoni da yawa, kamar kayan tattarawa, filaye, da sauransu.. galibi ana amfani da shi don abubuwan da za a iya zubar da su kamar kayan tebur da za a iya zubar da su, da kayan aikin lantarki da kula da lafiya.
Idan aka kwatanta da na gargajiya petrochemical kayayyakin, da makamashi amfani a cikin samar da polylactic acid ne kawai 20% zuwa 50% na petrochemical kayayyakin, da kuma carbon dioxide samar ne kawai 50% na petrochemical kayayyakin .Saboda haka, ci gaban polylactic acid deradable kayan wajibi ne don rage matsalolin muhalli da makamashi a duniya.

1.Biodegradability
Idan aka kwatanta da robobi na gargajiya, ana iya lalata acid polylactic zuwa CO2 da H2O ta ƙananan ƙwayoyin cuta da haske.Kayayyakin lalata halittu ba su da guba kuma marasa lahani kuma ba za su gurɓata muhalli ba.The monomer don samar da polylactic, wanda za a iya fermented da amfanin gona kamar shinkafa alkama da sukari gwoza ko irin kayan aikin gona.Saboda haka, da albarkatun kasa don samar da polylactic acid ne sabunta.Ana amfani da polylactic acid a matsayin kayan da za'a iya cirewa.
2. Bio-daidaituwa da Absorb-ability
Ana iya sanya polylactic acid ta hanyar acid ko enzyme don samar da lactic acid a cikin jikin mutum.A matsayin metabolite na sel, polylactic acid na iya ƙara haɓakawa ta hanyar enzymes a cikin jiki, don samar da CO2 da H2O.Sabili da haka, polylactic acid ba mai guba bane kuma mara lahani ga jikin ɗan adam haka ma yana da kyakkyawan daidaituwar yanayin halitta da ikon shayarwa, Polylactic acid an tabbatar da shi ta Hukumar Abinci da Magunguna ta Amurka wacce za'a iya amfani da ita azaman bio-material don dasawa a ciki. mutane.
3. Na'urar Mashin Jiki
A matsayin kayan aikin polymer na thermoplastic, poly lactic acid yana da kyawawan filastik da kaddarorin sarrafa jiki, tare da babban ma'anar narkewa, elasticity mai kyau da sassauci, da kyakkyawan ikon samar da thermal.Poly lactic acid kayan kamar polymer kayan kamar polypropylene (PP), polystyrene (PS), da kuma polypropylene ether guduro (PPO), za a iya aiki ta extrusion, mikewa, da allura gyare-gyaren.
