Ingabe i-PLA Iyahambisana Nemvelo?

I-Poly Lactic Acid iyi-polymer etholakala ngokwenza i-polymerizing i-lactic acid njengento eluhlaza eyinhloko futhi iwuhlobo olusha lwe-biodegradable material.Ngakho-ke,Intambo ye-PLAiyintambo ehambisana nemvelo.

Kunesizathu esenza ukuthi impahla yokuphrinta ye-3D ethandwa kakhulu futhi esetshenziswa kabanzi yamaphrinta e-FDM kube yi-PLA.Uma iqhathaniswa nezinye izinto zokwakha, kulula kakhulu ukuyiphrinta, okuyenza ibe umcu okahle wezimfundamakhwela.Ngokufanayo, ngokuvamile kukholelwa ukuthiI-PLA filamentisimeme futhi iphephe kakhulu kunezinye izinto.Uvelaphi lo mcabango?Yini i ukusimamaI-PLA engu-100% ehambisana nemvelo?Okulandelayo sizogxila ezindabeni ezihlobene ne-PLA.

1. Ikhiqizwa kanjani i-PLA?

I-PLA, eyaziwa nangokuthi i-Poly Lactic Acid, itholakala ezintweni ezingavuthiwe zemvelo ezivuselelekayo njengommbila.Khipha isitashi (i-glucose) ezitshalweni bese uguqulela ku-glucose ngokungeza ama-enzyme.Ama-microorganisms ayibilisa ibe yi-lactic acid, bese iguqulwa ibe i-polylactide.I-Polymerization ikhiqiza amaketanga ama-molecular amaketanga amade anezici zawo ezifana nalawo ama-polymers asekelwe ku-petroleum.

2. Kusho ukuthini “i-PLA’s biodegradable and compostable”?

Amagama athi “i-biodegradable and compostable” kanye nokwehlukaniswa kwawo kubalulekile futhi ngokuvamile awaqondwa kahle.U-Jan-Peter Willie wachaza: “Abantu abaningi badida “i-biodegradable” nethi “compostable.”Uma sikhuluma nje, “i-biodegradable” isho ukuthi into ingabola, kanti “I-Compostable” ngokuvamile isho ukuthi le nqubo izoholela ekwenziweni komquba.

Ngaphansi kwezimo ezithile ze-anaerobic noma i-aerobic, izinto "ezibolayo" zingabola.Nokho, cishe zonke izinto zokwakha zizobola ngokuhamba kwesikhathi.Ngakho-ke, izimo zemvelo eziqondile ezingabolayo kufanele zichazwe ngokucacile.Ukwenza umquba kuyinqubo yokwenziwa.Ngokwe-EN 13432 ejwayelekile yase-Europe, uma ezinyangeni eziyisithupha embonini yokwenza umquba, okungenani u-90% we-polymer noma iphakheji iguqulelwa ekukhishweni kwekhabhoni ngama-microorganisms, futhi okuqukethwe okuphezulu kwesengezo kungu-1%, i-polymer noma ukupakishwa kubhekwa “njengemvundisi”.Ikhwalithi yasekuqaleni ayinabungozi.Noma singasho ngamafuphi: “Konke ukuvundisa kuhlale kubola, kodwa akusiyo yonke i-biodegradation eyenza umquba”.

3. Ingabe intambo ye-PLA ihambisana nemvelo ngempela?

Uma kukhuthazwa izinto ze-PLA, igama elithi "biodegradable" livame ukusetshenziswa, okubonisa ukuthi i-PLA, njengodoti wasekhishini, ingabola emqubeni wasendlini noma endaweni yemvelo.Nokho, akunjalo.I-PLA filament ingachazwa ngokuthii-PLA filament eyonakele ngokwemvelo, kodwa ngaphansi kwezimo ezithile zokwenziwa komquba wezimboni, kulokhu, kufaneleka kakhulu ukusho ukuthi i-polymer biodegradable.Izimo zokwenza umquba wezimboni, okungukuthi, lapho kukhona amagciwane, ukulawula izinga lokushisa kanye nomswakama kuyisimo esidingekayo ukuze i-PLA yonakale ngempela.”Kuchaza uFlorent Port.U-Jan-Peter Willie wengeze wathi: “I-PLA iyavundiselwa, kodwa ingasetshenziswa kuphela ezitshalweni zokwenza umquba wezimboni.”

Ngaphansi kwalezi zimo zokwenza umquba wezimboni, i-PLA ingenziwa i-biodegraded phakathi kwezinsuku ukuya ezinyangeni.Izinga lokushisa kufanele libe ngaphezu kuka-55-70ºC.U-Nicholas uphinde waqinisekisa: “I-PLA ingacekelwa phansi kuphela ngaphansi kwezimo zokwenziwa komquba ezimbonini.”

4. Ukuthi i-PLA ingagaywa kabusha yini?

Ngokusho kochwepheshe abathathu, i-PLA ngokwayo ingaphinda isetshenziswe.Nokho, uFlorent Port waveza: “Okwamanje alikho iqoqo lemfucuza le-PLA elisemthethweni lokunyathelisa nge-3D.Eqinisweni, ishaneli yamanje yemfucumfucu yepulasitiki kunzima ukuhlukanisa i-PLA kwamanye ama-polymer (njenge-PET (amabhodlela amanzi).” Ngakho-ke, ngokobuchwepheshe, i-PLA iyakwazi ukugaywa kabusha, inqobo nje uma uchungechunge lomkhiqizo luqukethe kuphela i-PLA futhi lungangcoliswanga amanye amapulasitiki. .”

5. Ingabe i-PLA corn filament iwumucu ohambisana kakhulu nemvelo?

U-Nicolas Roux ukholelwa ukuthi ayikho enye indlela esimeme ngempela esikhundleni somucu wommbila, ”Ngeshwa, angiwazi ummbila wangempela oluhlaza futhi ophephile, ukuthi uzokhipha izinhlayiya yini emhlabeni noma olwandle noma ukwazi ukuziwohloza ngokwawo.Ngicabanga ukuthi lapho ukhetha izinto zokwakha, abakhiqizi bakhetha ukusebenzisa imicu ngokuphepha okuhambisanayo ngendlela enomthwalo wemfanelo.

I-Jiayi's100% intambo ye-PLA engaboliuzuze ukunconywa ngazwi linye phakathi kwamakhasimende.uma ufuna intambo efanelekile ewohlokayo, ungasithinta
