I-Poly Lactic Acid yipolima efunyenwe ngokwenza ipolymerizing lactic acid njengeyona imathiriyeli ekrwada kwaye luhlobo olutsha lwemathiriyeli enokubola.Ngoko ke,Intambo ye-PLAngumsonto ohambelana nokusingqongileyo.
Kukho isizathu sokuba eyona nto idumileyo nesetyenziswa ngokubanzi imathiriyeli yoshicilelo ye-3D yabashicileli be-FDM yiPLA.Xa kuthelekiswa nezinye izinto, kulula kakhulu ukuyiprinta, nto leyo eyenza ukuba ibe yeyona filament ifanelekileyo kubantu abangafundanga.Ngokufanayo, ngokuqhelekileyo kukholelwa ukubaI-PLA filamentlugcineke kwaye lukhuselekile kunezinye izixhobo.Ivela phi le ngcinga?Yintoni i uzinzo100% i-PLA exhasa indalo esingqongileyo?Okulandelayo siza kugxila kwimiba enxulumene ne-PLA.
1. Iveliswa njani iPLA?
I-PLA, ekwabizwa ngokuba yiPoly Lactic Acid, ifumaneka kwizinto ezihlaziyekayo zendalo ezifana nombona.Khipha isitashi (i-glucose) kwizityalo kwaye uyiguqule kwi-glucose ngokudibanisa i-enzymes.Iintsholongwane ziyibilisa ibe yi-lactic acid, ethi emva koko iguqulwe ibe yipolylactide.I-Polymerization ivelisa amatyathanga amade emolekyuli aneempawu ezifanayo nezo zepolymers ezisekelwe kwi-petroleum.
2. Ithetha ukuthini i-“PLA’s biodegradable and compostable”?
Amagama athi "i-biodegradable kunye ne-compostable" kunye nomahluko wabo ubalulekile kwaye uhlala ungaqondwa kakuhle.UJan-Peter Willie wacacisa: “Abantu abaninzi babhidanisa “i-biodegradable” kunye “necompostable.”Xa sithetha ngokubanzi, “i-biodegradable” ithetha ukuba into inokonakaliswa, ngelixa “I-Compostable” ngokuqhelekileyo ithetha ukuba le nkqubo iya kubangela ukuvundisa.
Phantsi kweemeko ezithile ze-anaerobic okanye i-aerobic, "i-biodegradable" imathiriyeli inokubola.Nangona kunjalo, phantse zonke izixhobo ziya kubola ngokuhamba kwexesha.Ke ngoko, ezona meko zichanekileyo zokusingqongileyo ezinokubola kufuneka zichazwe ngokucacileyo.Ukwenza umgquba yinkqubo eyenziweyo.Ngokomgangatho waseYurophu we-EN13432, ukuba kwiinyanga ezintandathu kwisityalo sokubumba umgquba, ubuncinane i-90% yepolymer okanye ukupakishwa iguqulwa ibe yi-carbon emissions yi-microorganisms, kwaye umxholo ophezulu we-additive yi-1%, i-polymer okanye ukupakishwa. ithathwa njenge "compostable".Umgangatho wokuqala awunabungozi.Okanye sinokuthi ngamafutshane: "Yonke i-composting isoloko i-biodegradable, kodwa akuyiyo yonke i-biodegradation i-composting".
3. Ngaba ngokwenene umsonto wePLA uhambelana nokusingqongileyo?
Xa kukhuthazwa izinto ze-PLA, igama elithi "i-biodegradable" lihlala lisetyenziswa, elibonisa ukuba i-PLA, njengenkunkuma yasekhitshini, inokubola kwi-compost yasekhaya okanye kwindawo yendalo.Nangona kunjalo, oku akunjalo.I-PLA filament inokuchazwa njengeiFilament yePLA eyonakele ngokwendalo, kodwa phantsi kweemeko ezithile ze-composting ye-industrial composting, kule meko, kulungele ngakumbi ukuthetha ukuba i-polymer biodegradable.Iimeko zokwenziwa komgquba kwimizi-mveliso, oko kukuthi, phambi kweentsholongwane, ukulawula ubushushu kunye nokufuma yimeko efunekayo ukuze iPLA yonakale ngokwenene.UFlorent Port wachaza.UJan-Peter Willie wongeze wathi: "I-PLA iyavundiswa, kodwa inokusetyenziswa kuphela kwizityalo zokuvundisa kwimizi-mveliso."
Phantsi kwezi meko zokwenziwa komgquba kwimizi-mveliso, iPLA inokonakaliswa kwisithuba seentsuku ukuya kwiinyanga.Ubushushu kufuneka bube ngaphezulu kwe 55-70ºC.UNicholas ukwaqinisekisile wathi: “I-PLA inokonakaliswa kuphela phantsi kweemeko zokwenziwa komgquba kwimizi-mveliso.”
4. Ingaba iPLA inokuphinda isetyenziswe?
Ngokutsho kweengcali ezintathu, i-PLA ngokwayo inokuphinda isetyenziswe.Nangona kunjalo, i-Florent Port yachaza: “Okwangoku akukho ngqokelela yenkunkuma esemthethweni yePLA yoshicilelo lwe-3D.Enyanisweni, i-channel yenkunkuma yeplastiki yangoku kunzima ukuhlukanisa i-PLA kwezinye iipolymers (ezifana ne-PET (iibhotile zamanzi) ". Ngoko ke, ngokobuchwephesha, i-PLA iphinda isetyenziswe, ngaphandle kokuba uluhlu lwemveliso lubandakanya kuphela i-PLA kwaye alungcoliswanga ngezinye iiplastiki. .”
5. Ingaba iPLA corn filament yeyona filament ihambelana nokusingqongileyo?
UNicolas Roux ukholelwa ukuba ayikho enye indlela ezinzileyo yombona, “Ngelishwa, andiwazi owona mbona wokwenyani oluhlaza kunye nokhuselekileyo, nokuba ziya kukhupha amasuntswana emhlabeni okanye elwandle okanye zikwazi ukuzimoshela ngokwazo.Ndicinga ukuba xa ukhetha izinto eziphathekayo, abavelisi bakhetha ukusebenzisa i-filaments kunye nokhuseleko oluhambelanayo ngendlela enoxanduva.
IJiayi'sI-100% yomsonto we-PLA onokubolaiphumelele indumiso ngamxhelo mnye phakathi kwabathengi.Ukuba ujonge umsonto owonakaliswayo, ungaqhagamshelana nathi
