Poly Lactic Acid yog ib qho polymer tau los ntawm polymerizing lactic acid ua cov khoom siv tseem ceeb thiab yog ib hom tshiab ntawm cov khoom siv biodegradable.Yog li ntawd,PLA xov pajyog ib puag ncig tus phooj ywg yarn.
Yog vim li cas vim li cas thiaj li nrov tshaj plaws thiab siv dav siv 3D luam ntawv rau FDM tshuab luam ntawv yog PLA.Piv nrog rau lwm cov ntaub ntawv, nws yooj yim heev rau luam, uas ua rau nws zoo tagnrho filament rau amateurs.Ib yam li ntawd, nws yog feem ntau ntseeg tiasPLA fiber ntauyog ruaj khov thiab muaj kev nyab xeeb dua li lwm yam khoom siv.Qhov kev xav no los ntawm qhov twg?Qhov kuv sustainability ntawm100% ib puag ncig-riendly PLA?Tom ntej no peb yuav tsom mus rau cov teeb meem ntsig txog PLA.
1. PLA ua li cas?
PLA, tseem hu ua Poly Lactic Acid, yog tau los ntawm cov khoom siv tshiab tshiab xws li pob kws.Extract hmoov nplej (glucose) los ntawm cov nroj tsuag thiab hloov mus rau cov piam thaj los ntawm kev ntxiv cov enzymes.Cov kab mob ferment nws mus rau lactic acid, uas tom qab ntawd hloov mus rau polylactide.Polymerization tsim cov saw hlau ntev molecular uas nws cov khoom zoo ib yam li cov roj av-raws li polymers.
2. "PLA's biodegradable thiab compostable" txhais li cas?
Cov ntsiab lus "biodegradable thiab compostable" thiab lawv qhov txawv yog qhov tseem ceeb thiab feem ntau to taub yuam kev.Jan-Peter Willie tau piav qhia tias: "Ntau tus neeg tsis meej pem "biodegradable" nrog "compostable."Hais lus dav dav, "biodegradable" txhais tau hais tias ib yam khoom tuaj yeem biodegraded, thaum "Compostable" feem ntau txhais tau tias cov txheej txheem no yuav ua rau composting.
Nyob rau hauv tej yam kev mob anaerobic lossis aerobic, cov ntaub ntawv "biodegradable" tuaj yeem decomposed.Txawm li cas los xij, yuav luag tag nrho cov ntaub ntawv yuav decompose nrog lub sijhawm dhau mus.Yog li ntawd, qhov tseeb ib puag ncig uas yog biodegradable yuav tsum tau txhais kom meej.Composting yog txheej txheem tsim khoom.Raws li European tus qauv EN13432, yog hais tias nyob rau hauv rau lub hlis nyob rau hauv ib tug industrial composting nroj tsuag, tsawg kawg yog 90% ntawm cov polymer los yog ntim yog hloov mus rau carbon emissions los ntawm cov kab mob, thiab lub siab tshaj plaws cov ntsiab lus ntawm cov additives yog 1%, lub polymer los yog ntim. suav tias yog "compostable".Thawj qhov zoo yog tsis muaj mob.Lossis peb tuaj yeem hais hauv cov ntsiab lus: "Tag nrho cov composting yog ib txwm biodegradable, tab sis tsis yog tag nrho biodegradation yog composting".
3. PLA xov paj puas yog ib puag ncig zoo?
Thaum txhawb PLA cov ntaub ntawv, lo lus "biodegradable" feem ntau yog siv, uas qhia tau hais tias PLA, xws li cov khib nyiab hauv chav ua noj, tuaj yeem rot hauv tsev compost lossis ib puag ncig ntuj.Txawm li cas los xij, qhov no tsis yog qhov xwm txheej.PLA filament tuaj yeem piav raws liNaturally degradable PLA filament, tab sis nyob rau hauv tej yam kev mob ntawm industrial composting, nyob rau hauv cov ntaub ntawv no, nws yog tsim nyog hais tias nws yog ib tug biodegradable polymer.Industrial composting tej yam kev mob, piv txwv li nyob rau hauv lub xub ntiag ntawm microorganisms, tswj kub thiab av noo yog ib tug tsim nyog mob rau PLA kom degradable tiag tiag. "Florent Port piav qhia.Jan-Peter Willie ntxiv: "PLA yog compostable, tab sis nws tsuas yog siv tau rau hauv kev lag luam composting nroj tsuag."
Nyob rau hauv cov kev lag luam composting no, PLA tuaj yeem biodegraded nyob rau hauv hnub rau hli.Qhov kub yuav tsum siab tshaj 55-70ºC.Nicholas kuj tau lees tias: "PLA tuaj yeem tsuas yog biodegraded nyob rau hauv kev lag luam composting tej yam kev mob."
4. Puas yog PLA tuaj yeem rov ua dua?
Raws li peb tus kws tshaj lij, PLA nws tus kheej tuaj yeem rov ua dua tshiab.Txawm li cas los xij, Florent Port tau taw qhia: "Tam sim no tsis muaj PLA pov tseg pov tseg rau 3D luam ntawv.Qhov tseeb, cov yas khib nyiab tam sim no yog qhov nyuaj rau kev paub qhov txawv ntawm PLA los ntawm lwm cov polymers (xws li PET (cov fwj dej) ). ”
5. Puas yog PLA pob kws filament yog ib puag ncig zoo tshaj plaws filament?
Nicolas Roux ntseeg hais tias tsis muaj lwm txoj hauv kev rau cov pob kws filament, "Hmoov tsis zoo, kuv tsis paub qhov tseeb ntsuab thiab nyab xeeb pob kws filament, txawm tias lawv yuav tawm hauv lub ntiaj teb lossis dej hiav txwv los yog muaj peev xwm biodegrade lawv tus kheej.Kuv xav tias thaum xaiv cov ntaub ntawv, cov tuam txhab nyiam siv cov filaments nrog kev nyab xeeb sib xws hauv lub luag haujlwm.
Jiayi cov100% biodegradable PLA xov pajtau yeej unanimous qhuas ntawm cov neeg muas zaub.f koj tab tom nrhiav rau qhov tsim nyog degradable emvronmentally tus phooj ywg xov paj, koj tuaj yeem tiv tauj peb
