Dab tsi yog pla zaj yeeb yaj kiab?
Pla zaj duab xis yog biodegradable thiab ib puag ncig-phooj ywg zaj duab xis ua los ntawm cov pob kws resin.orgeg cov khoom siv xws li cov nplej pob kws ua pob txha lossis cov suab thaj. Siv cov khoom siv biomass ua rau cov khoom siv PLA sib txawv los ntawm feem ntau plastics, uas yog tsim siv cov pob txha taub hau los ntawm cov roj av distillation thiab polymerization ntawm roj av.
Txawm hais tias cov khoom siv nyoos sib txawv, PLA tuaj yeem tsim tau siv tib cov cuab yeej ua petrochemical plastics, ua cov txheej txheem tsim khoom siv tus nqi tau zoo. Pla yog qhov thib ob tsim nyog Bioplastic (tom qab thermoplastic starch) thiab muaj cov yam ntxwv zoo sib xws rau polypropylene (PE), lossis polystyrene (ps), nrog rau kev ua biodegrade.
Zaj duab xis muaj qhov pom tseeb zoo,Zoo tensile lub zog,thiab zoo txhav zoo thiab tawv.our Pla Films muaj ntawv pov thawj rau nplooj lwg raws li EN 13432 Daim Ntawv Pov Thawj
PLA zaj duab xis ua pov thawj los ua ib qho ntawm cov ntim khoom zoo tshaj plaws hauv kev lag luam ntim khoom, thiab tam sim no tau siv nyob rau hauv kev lag luam ntim khoom, khoom plig zoo li mov ci thiab taum noj.
Wow pla yog dab tsi?
PLA yog polyester (polymer (polymer uas muaj cov pab pawg Ester Lactic acid tuaj yeem tsim los ntawm cov kab mob uas muaj kab mob ntawm cov carbohydrate nyob rau hauv cov xwm txheej. Hauv kev lag luam-teev ntau lawm cov roj ntsha li chiv, cov carbohydrate qhov chaw ntawm kev xaiv tuaj yeem yog cov partic party, lossis cov kab mob hauv qab, ua rau cov txheej txheem muaj kev sib luag thiab txuas ntxiv mus ntxiv thiab txuas ntxiv mus ntxiv thiab txuas ntxiv mus ntxiv thiab txuas ntxiv mus ntxiv thiab txuas ntxiv mus ntxiv.
Qhov Kom Zoo Ib Lub Pla
PLA yog biodegradable nyob rau hauv cov kev lag luam sib txawv thiab yuav tawg nyob rau hauv kev xaiv kom zoo nkauj uas tuaj yeem coj ib nrab ntawm kev txiav txim siab thiab ua kom tiav tsim microplastics.
Cov txheej txheem tsim khoom rau PLA kuj yog ntau ib puag ncig tus phooj ywg zoo dua li ntawm cov khoom siv ib txwm ua los ntawm cov khoom siv pob txha ua kom zoo. Raws li kev tshawb fawb, cov pa roj carbon emissions cuam tshuam nrog cov txheej txheem PLA yog 80% qis dua li cov yas tsoos (khoom siv).
PLA tuaj yeem rov ua dua tshiab vim nws tuaj yeem tawg rau nws thawj Monomer los ntawm cov txheej txheem thermal depolymerization lossis los ntawm hydrolysis. Qhov tshwm sim yog cov kev daws teeb meem monomer uas tuaj yeem ua kom huv thiab siv rau cov hlua PLA tsim khoom tsis muaj kev poob zoo.
