Acide Poly Lactic Acide ni polymer yabonetse hakoreshejwe polymerizing acide lactique nkibikoresho nyamukuru kandi ni ubwoko bushya bwibinyabuzima bishobora kwangirika.Kubwibyo,PLA yarnni umugozi wangiza ibidukikije.
Hariho impamvu ituma ibikoresho byo gucapa 3D bizwi cyane kandi bikoreshwa cyane kubicapiro bya FDM ni PLA.Ugereranije nibindi bikoresho, biroroshye cyane gucapa, bigatuma iba filime nziza kubakunzi.Mu buryo nk'ubwo, muri rusange abantu bemeza koUmutwe wa PLAbiraramba kandi bifite umutekano kurusha izindi nyababyeyi.Iki gitekerezo kiva he?Ibyo i biramba100% ibidukikije-bidahwitse PLA?Ubutaha tuzibanda kubibazo bijyanye na PLA.
1. Nigute PLA ikorwa?
PLA, izwi kandi nka Poly Lactic Acide, iboneka mubikoresho fatizo byongerewe imbaraga nkibigori.Kuramo ibinyamisogwe (glucose) mubihingwa hanyuma ubihindure glucose wongeyeho enzymes.Microorganismes irayihindura aside ya lactique, hanyuma igahinduka polylactide.Polymerisation itanga urunigi rurerure rw'iminyururu ifite imitungo isa n'iy'ibikomoka kuri peteroli.
2. “PLA's biodegradable and compostable” isobanura iki?
Ijambo "biodegradable and compostable" no gutandukanya kwabo ni ngombwa kandi akenshi ntibisobanutse.Jan-Peter Willie yabisobanuye agira ati: “Abantu benshi bitiranya“ biodegradable ”n '“ ifumbire mvaruganda. ”Muri rusange, "biodegradable" bivuze ko ikintu gishobora kuba ibinyabuzima, mugihe "Compostable" mubisanzwe bivuze ko iyi nzira izavamo ifumbire.
Mubihe bimwe na bimwe bya anaerobic cyangwa aerobic, ibikoresho "biodegradable" birashobora kubora.Nyamara, ibikoresho hafi ya byose bizabora hamwe nigihe cyigihe.Kubwibyo, ibidukikije nyabuzima bishobora kwangirika bigomba gusobanurwa neza.Ifumbire ni inzira yubukorikori.Ukurikije ibipimo ngenderwaho by’iburayi EN13432, niba mu mezi atandatu mu ruganda rukora ifumbire mvaruganda, byibuze 90% ya polymer cyangwa ibipfunyika bihindurwamo imyuka ihumanya ikirere na mikorobe, kandi ibyinshi mubyongeweho ni 1%, polymer cyangwa gupakira ni bifatwa nk '“ifumbire mvaruganda”.Ubwiza bwumwimerere ntacyo butwaye.Cyangwa dushobora kuvuga muri make: "Ifumbire mvaruganda ihora ibora, ariko ntabwo biodegradation yose ifumbira".
3. Ese koko ubudodo bwa PLA bwangiza ibidukikije?
Iyo utezimbere ibikoresho bya PLA, ijambo "biodegradable" rikoreshwa kenshi, ryerekana ko PLA, nkimyanda yo mugikoni, ishobora kubora ifumbire mvaruganda cyangwa ibidukikije.Ariko, ntabwo aribyo.Filime ya PLA irashobora gusobanurwa nkmubisanzwe kwangirika kwa PLA filament, ariko mubihe byihariye byo gufumbira inganda, muriki gihe, birakwiye cyane kuvuga ko ari polymer ibinyabuzima.Imiterere y’ifumbire mvaruganda, ni ukuvuga imbere ya mikorobe, kugenzura ubushyuhe n’ubushuhe ni ikintu cya ngombwa kugira ngo PLA ibe yangirika. ”Icyambu cya Florent cyasobanuwe.Jan-Peter Willie yongeyeho ati: “PLA ifumbire mvaruganda, ariko irashobora gukoreshwa gusa mu nganda zikora ifumbire mvaruganda.”
Muri ibi bihe byifumbire mvaruganda, PLA irashobora kwangirika muminsi mike.Ubushyuhe bugomba kuba hejuru ya 55-70ºC.Nicholas yemeje kandi ati: “PLA irashobora kwangirika gusa mu gihe cy'ifumbire mvaruganda.”
4. Niba PLA ishobora gukoreshwa neza?
Nk’uko abahanga batatu babivuga, PLA ubwayo irashobora gukoreshwa neza.Icyakora, icyambu cya Florent cyagaragaje: “Kugeza ubu nta cyegeranyo cya PLA cyemewe cyo gucapa 3D.Mubyukuri, umuyoboro w’imyanda wa pulasitiki urimo biragoye gutandukanya PLA nizindi polymers (nka PET (amacupa y’amazi) ". Kubwibyo rero, mu buryo bwa tekiniki, PLA irashobora gukoreshwa, hashingiwe ko urutonde rwibicuruzwa rugizwe na PLA gusa kandi ntirwandujwe n’andi mashanyarazi. . ”
5. Ese filime y'ibigori ya PLA niyo yangiza ibidukikije cyane?
Nicolas Roux yizera ko nta bundi buryo burambye bushobora gukoreshwa mu guhunika ibigori, "Ikibabaje ni uko ntazi ibigori nyabyo kandi bitekanye, byaba byohereza uduce duto ku isi cyangwa inyanja cyangwa bakabasha kwangiza ibinyabuzima ubwabo.Ndibwira ko mugihe uhisemo ibikoresho, ababikora bahitamo gukoresha filaments hamwe numutekano uhuje muburyo bushinzwe.
Jiayi's100% biodegradable PLA yarnyatsindiye ishimwe bose mubakiriya.f urimo ureba ibyangiritse byangirika emvronmentally yintambara, urashobora kutwandikira
