Polylactic acid (PLA) yog ib qho polymerized nrog lactic acid ua cov khoom siv tseem ceeb, uas yog tag nrho cov khoom siv thiab tuaj yeem tsim dua tshiab.Cov txheej txheem ntau lawm ntawm polylactic acid yog tsis muaj kuab paug, thiab cov khoom tuaj yeem biodegraded kom ua tiav cov xwm txheej, yog li nws yog cov khoom siv ntsuab zoo tagnrho.Polylactic acid ((PLA)) yog ib yam tshiab ntawm biodegradable khoom raucov khoom yas, 3D luam ntawv.Cov hmoov txhuv nplej siab tau muab rho tawm los ntawm cov khoom siv txuas ntxiv mus ntxiv (xws li pob kws) yog tsim rau hauv lactic acid los ntawm fermentation thiab tom qab ntawd hloov mus rau hauv polylactic acid los ntawm polymer synthesis.

Poly (lactic acid) muaj biodegradability zoo heev thiab tuaj yeem degraded los ntawm 100% ntawm cov kab mob hauv cov av hauv ib xyoos tom qab tso tseg, ua rau carbon dioxide thiab dej thiab tsis muaj kuab paug rau ib puag ncig.Ua tau tiag tiag "los ntawm xwm, koom nrog xwm".Lub ntiaj teb cov pa roj carbon dioxide emissions raws li xov xwm tshaj tawm, lub ntiaj teb no kub yuav nce mus rau 60 ℃ nyob rau hauv 2030. Ordinary plastics tseem incinerated, ua rau ib tug loj npaum li cas ntawm cov tsev xog paj gases yuav tawm mus rau saum huab cua, thaum polylactic acid yog faus rau hauv av rau degradation. .Qhov tshwm sim carbon dioxide mus ncaj qha rau hauv av organic teeb meem los yog absorbed los ntawm cov nroj tsuag, yuav tsis tawm mus rau hauv huab cua, yuav tsis ua rau Greenhouse Effect.

Poly (lactic acid) yog tsim rau ntau yam kev ua xws li tshuab moulding thiabtxhaj tshuaj molding.Nws yog ib qho yooj yim rau txheej txheem thiab dav siv.Nws tuaj yeem siv los ua txhua yam ntawm cov thawv ntim khoom noj, ntim khoom noj, cov thawv ntim khoom noj ceev ceev, cov ntaub ntawv tsis-woven, kev lag luam thiab cov ntaub npuag los ntawm kev lag luam mus rau pej xeem siv.Thiab tom qab ntawd ua tiav rau hauv cov ntaub ntawv ua liaj ua teb, kev kho mob fabrics, rags, cov khoom siv huv, sab nraum zoov los tiv thaiv ultraviolet fabrics, tsev pheeb suab ntaub, hauv pem teb txaj thiab lwm yam, kev lag luam kev cia siab yog heev.Nws tuaj yeem pom tias nws cov khoom siv kho tshuab thiab lub cev zoo.

Cov yam ntxwv ntawm lub cev ntawm polylactic acid (PLA) thiab petrochemical hluavtaws hluavtaws yog qhov zoo sib xws, uas yog, nws tuaj yeem siv los ua ntau yam khoom siv.Polylactic acid kuj muaj qhov zoo glossiness thiab pob tshab, uas zoo ib yam li cov yeeb yaj kiab ua los ntawm polystyrene thiab tsis tuaj yeem muab los ntawm lwm cov khoom siv biodegradable.
