Poly Lactic Acid ndi polima yomwe imapezedwa polima lactic acid ngati chinthu chachikulu ndipo ndi mtundu watsopano wazinthu zosawonongeka.Chifukwa chake,Mtengo wa PLAndi ulusi wokonda zachilengedwe.
Pali chifukwa chake chosindikizira cha 3D chodziwika kwambiri komanso chogwiritsidwa ntchito kwambiri kwa osindikiza a FDM ndi PLA.Poyerekeza ndi zipangizo zina, ndizosavuta kusindikiza, zomwe zimapangitsa kuti ikhale yabwino kwa amateurs.Mofananamo, anthu ambiri amakhulupirira zimenezoZithunzi za PLAndizokhazikika komanso zotetezeka kuposa zida zina.Kodi kulingalira kumeneku kumachokera kuti?Zomwe ndikukhazikika100% zachilengedwe-riendly PLA?Kenako tikambirana za PLA.
1. Kodi PLA imapangidwa bwanji?
PLA, yomwe imadziwikanso kuti Poly Lactic Acid, imapezeka kuchokera kuzinthu zongowonjezwdwanso zachilengedwe monga chimanga.Chotsani wowuma (shuga) kuchokera ku zomera ndikusintha kukhala shuga powonjezera ma enzyme.Tizilombo tating'onoting'ono timatulutsa lactic acid, yomwe imasinthidwa kukhala polylactide.Polymerization imapanga maunyolo aatali a molekyulu omwe katundu wake amafanana ndi ma polima opangidwa ndi petroleum.
2. Kodi "PLA's biodegradable and compotable" ikutanthauza chiyani?
Mawu akuti "biodegradable and compostable" ndi kusiyana kwawo n'kofunika ndipo nthawi zambiri samveka.Jan-Peter Willie anafotokoza kuti: “Anthu ambiri amasokoneza mawu akuti “biodegradable” ndi “compostable.”Kunena zochulukira, "biodegradable" amatanthauza kuti chinthu chikhoza kusinthidwa kukhala biodegraded, pomwe "Compostable" nthawi zambiri amatanthauza kuti izi zipangitsa kuti compost.
Pazinthu zina za anaerobic kapena aerobic, zinthu "zowonongeka" zimatha kuwola.Komabe, pafupifupi zipangizo zonse zidzawola pakapita nthawi.Choncho, malo enieni a chilengedwe omwe amatha kuwonongeka ndi biodegradable ayenera kufotokozedwa momveka bwino.Kompositi ndi njira yopangira.Malinga ndi muyezo waku Europe wa EN13432, ngati mkati mwa miyezi isanu ndi umodzi mufakitale yopanga kompositi, pafupifupi 90% ya polima kapena zonyamula zimasinthidwa kukhala mpweya wa kaboni ndi tizilombo, ndipo zowonjezera zowonjezera ndi 1%, polima kapena ma CD. amatengedwa ngati "compostable".Ubwino wapachiyambi ndi wopanda vuto.Kapena tinganene mwachidule kuti: "Kompositi yonse nthawi zonse imakhala yowonongeka, koma sikuti biodegradation yonse ndi composting".
3. Kodi ulusi wa PLA ndi wogwirizana ndi chilengedwe?
Polimbikitsa zipangizo za PLA, mawu oti "biodegradable" amagwiritsidwa ntchito nthawi zambiri, zomwe zimasonyeza kuti PLA, monga zinyalala zakukhitchini, zimatha kuvunda mu kompositi yapakhomo kapena chilengedwe.Komabe, izi sizili choncho.PLA filament ikhoza kufotokozedwa ngatimwachibadwa degradable PLA filament, koma pansi pa zikhalidwe zenizeni za composting ya mafakitale, mu nkhaniyi, ndi bwino kunena kuti ndi polima yowonongeka.Mikhalidwe ya kompositi ya mafakitale, mwachitsanzo, pamaso pa tizilombo tating'onoting'ono, kuwongolera kutentha ndi chinyezi ndikofunikira kuti PLA ikhale yowonongeka. "Florent Port anafotokoza.Jan-Peter Willie anawonjezera kuti: "PLA ndi compostable, koma itha kugwiritsidwa ntchito m'mafakitale opanga kompositi."
Pansi pamikhalidwe ya kompositi yamafakitale iyi, PLA ikhoza kusinthidwa mkati mwa masiku mpaka miyezi.Kutentha kuyenera kukhala kopitilira 55-70ºC.Nicholas adatsimikiziranso kuti: "PLA ingowonongeka pokhapokha ngati pali kompositi yamakampani."
4. Kaya PLA ikhoza kubwezeretsedwanso?
Malinga ndi akatswiri atatuwa, PLA yokha imatha kubwezeretsedwanso.Komabe, Florent Port ananena kuti: “Pakali pano palibe boma la PLA lotolera zinyalala zosindikizira za 3D.M'malo mwake, njira yapano ya zinyalala za pulasitiki ndizovuta kusiyanitsa PLA ndi ma polima ena (monga PET (mabotolo amadzi) ". Chifukwa chake, mwaukadaulo, PLA imatha kubwezeretsedwanso, malinga ngati mndandanda wazinthuzo ungokhala ndi PLA yokha ndipo sunaipitsidwe ndi mapulasitiki ena. .”
5. Kodi ulusi wa chimanga wa PLA ndiwomwe umateteza chilengedwe?
Nicolas Roux akukhulupirira kuti palibe njira ina yodalirika yosinthira ulusi wa chimanga, "Tsoka ilo, sindikudziwa ulusi weniweni wobiriwira komanso wotetezeka, kaya ungatulutse tinthu ting'onoting'ono padziko lapansi kapena m'nyanja kapenanso kuti zitha kudziwononga zokha.Ndikuganiza kuti posankha zipangizo, opanga amakonda kugwiritsa ntchito filaments ndi chitetezo chogwirizana mwanzeru.
Jiayi pa100% ulusi wa PLA wosawonongekawapeza chitamando chimodzi pakati pa makasitomala.Ngati mukuyang'ana ulusi wowonongeka wokhoza kuwonongeka, mutha kulumikizana nafe
