PLA zaj duab xis yog dab tsi?
PLA zaj duab xis yog biodegradable thiab ib puag ncig-phooj ywg zaj duab xis ua los ntawm pob kws-raws li Polylactic Acid resin.organic qhov chaw xws li pob kws starch los yog qab zib pas nrig.Siv cov peev txheej biomass ua rau PLA ntau lawm sib txawv ntawm cov yas feem ntau, uas yog tsim los ntawm cov fossil fuels los ntawm distillation thiab polymerization ntawm roj av.
Txawm hais tias muaj qhov sib txawv ntawm cov khoom siv raw, PLA tuaj yeem tsim tau siv tib yam khoom siv xws li petrochemical plastics, ua rau PLA cov txheej txheem tsim tau tus nqi zoo.PLA yog thib ob feem ntau tsim bioplastic (tom qab cov hmoov txhuv nplej siab thermoplastic) thiab muaj cov yam ntxwv zoo sib xws rau polypropylene (PP), polyethylene (PE), los yog polystyrene (PS), thiab yog biodegradeable.
Zaj duab xis muaj zoo clarity,Zoo tensile zog,thiab zoo nruj thiab toughness.Our PLA films tau ntawv pov thawj rau composting raws li EN 13432 daim ntawv pov thawj
PLA zaj duab xis ua pov thawj tias yog ib qho ntawm cov khoom ntim zoo tshaj plaws hauv kev lag luam ntim khoom lag luam, thiab tam sim no tau siv rau hauv pob khoom rau paj, khoom plig, khoom noj xws li qhob cij thiab biscuit, taum kas fes.
YUAV UA LI CAS PLA?
PLA yog ib qho polyester (polymer uas muaj cov ester pawg) ua nrog ob lub monomers los yog lub tsev thaiv: lactic acid, thiab lactide.Lactic acid tuaj yeem tsim los ntawm cov kab mob fermentation ntawm carbohydrate qhov chaw raws li kev tswj xyuas.Nyob rau hauv kev lag luam-scale zus tau tej cov lactic acid, cov carbohydrate qhov chaw ntawm kev xaiv yuav ua tau pob kws starch, cassava keeb kwm, los yog qab zib, ua tus txheej txheem sustainable thiab txuas ntxiv mus.
ENVIRONMENTAL ADVANTAGE NTAWM PLA
PLA yog biodegradable nyob rau hauv kev lag luam composting tej yam kev mob thiab yuav tawg nyob rau hauv kaum ob lub lis piam, ua rau nws ib tug ntau dua kev xaiv ib puag ncig thaum nws los txog rau plastics nyob rau hauv sib piv rau cov tsoos plastics uas yuav siv sij hawm ntau pua xyoo los decompose thiab xaus mus tsim microplastics.
Cov txheej txheem tsim khoom rau PLA tseem yog ib puag ncig zoo dua li cov khoom siv niaj hnub ua los ntawm cov khoom siv pob txha finite.Raws li kev tshawb fawb, cov pa roj carbon emissions cuam tshuam nrog PLA ntau lawm yog 80% qis dua li cov khoom siv yas (qhov chaw).
PLA tuaj yeem rov ua dua tshiab raws li nws tuaj yeem tawg mus rau nws qhov qub monomer los ntawm cov txheej txheem thermal depolymerization lossis los ntawm hydrolysis.Qhov tshwm sim yog cov tshuaj monomer uas tuaj yeem ua kom huv thiab siv rau tom qab PLA ntau lawm yam tsis muaj kev poob zoo.
