Iyini i-PLA?Konke Odinga Ukukwazi
Ingabe ubufuna enye indlela yamapulasitiki asekelwe ku-petroleum kanye nokupakisha?Imakethe yanamuhla iya ngokuya ibhekela emikhiqizweni ebolayo kanye ne-eco-friendly eyenziwe ngezinsiza ezivuselelekayo.
Ifilimu ye-PLAimikhiqizo isiphenduke enye yezinketho ezidume kakhulu ezibolayo nezihambisana nemvelo emakethe.Ucwaningo lwango-2017 lwathola ukuthi ukufaka amapulasitiki asekelwe ku-petroleum esikhundleni se-bio-based kunganciphisa ukukhishwa kwegesi ebamba ukushisa ezimbonini ngama-25%.
Iyini i-PLA?
I-PLA, noma i-polylactic acid, ikhiqizwa kunoma yimuphi ushukela ovutshelwayo.I-PLA eminingi yenziwe ngommbila ngoba ummbila ungowoshukela oshibhe kakhulu futhi otholakala kakhulu emhlabeni jikelele.Nokho, umoba, impande ye-tapioca, umdumbula, ne-sugar beet pulp ngezinye izindlela.
Njengezinto eziningi ezihlobene namakhemikhali, inqubo yokudala i-PLA kusuka kummbila iyinkimbinkimbi kakhulu.Nokho, ingachazwa ngezinyathelo ezimbalwa eziqondile.
Yenziwa kanjani imikhiqizo ye-PLA?
Izinyathelo eziyisisekelo zokwakha i-polylactic acid kusuka kummbila zimi kanje:
1. Isitashi sokuqala sombila kufanele siguqulwe sibe ushukela ngokusebenzisa inqubo yomshini ebizwa ngokuthi i-wet milling.Ukugaya okumanzi kwehlukanisa isitashi nezinhlamvu.I-Acid noma ama-enzyme ayengezwa uma lezi zingxenye sezihlukanisiwe.Khona-ke, ziyashiswa ukuguqula isitashi sibe yi-dextrose (aka ushukela).
2. Okulandelayo, i-dextrose iyavutshelwa.Enye yezindlela ezivame kakhulu zokuvutshelwa ihlanganisa ukufaka amagciwane e-Lactobacillus ku-dextrose.Lokhu, futhi, kudala i-lactic acid.
3. I-lactic acid ibe isiguqulwa ibe i-lactide, i-dimer ye-ring-form ye-lactic acid.Lawa ma-molecule e-lactide ahlangana ndawonye ukuze enze ama-polymer.
4. Umphumela we-polymerization izingcezu ezincane zepulasitiki ye-polylactic acid eluhlaza engaguqulwa ibe uxhaxha lwemikhiqizo yepulasitiki ye-PLA.
Yiziphi izinzuzo zemikhiqizo ye-PLA?
I-PLA idinga amandla angaphansi ngo-65% ukukhiqiza kunamapulasitiki endabuko, asekelwe ku-petroleum.Iphinde ikhiphe amagesi abamba ukushisa angaphansi kwama-68%.Futhi akugcini lapho:
Izinzuzo zemvelo:
Uma kuqhathaniswa namapulasitiki e-PET - Ngaphezu kuka-95% wamapulasitiki omhlaba enziwa ngegesi yemvelo noma uwoyela ongahluziwe.Amapulasitiki asekelwe kuphethiloli awagcini nje ngokuba yingozi;nazo ziyinsiza enomkhawulo.Imikhiqizo ye-PLA yethula ukushintshwa okusebenzayo, okuvuselelekayo, nokuqhathanisekayo.
Isisekelo se-bio– Izinto zomkhiqizo osuselwe ku-bio zitholakala kwezolimo ezivuselelekayo noma izitshalo.Ngenxa yokuthi yonke imikhiqizo ye-PLA ivela kusitashi sikashukela, i-polylactic acid ibhekwa njenge-bio-based.
I-Biodegradable- Imikhiqizo ye-PLA ifinyelela izindinganiso zamazwe ngamazwe zokuwohloka kwemvelo, okonakele ngokwemvelo esikhundleni sokunqwabelana ezindaweni zokulahla imfucumfucu.Idinga izimo ezithile ukuze zehlise isithunzi ngokushesha.Endaweni yokwenza umquba wezimboni, ingabhidlika ezinsukwini ezingama-45-90.
Ayikhiphi intuthu enobuthi - Ngokungafani namanye amapulasitiki, ama-bioplastic awakhiphi intuthu enobuthi lapho eshiswa.
I-Thermoplastic– I-PLA iyi-thermoplastic, ngakho iyabumbeka futhi ithambile uma ishiselwa ezingeni layo lokushisa elincibilikayo.Ingaqiniswa futhi ibunjwe ngomjovo ibe amafomu ahlukahlukene okwenza kube inketho enhle kakhulu yokupakishwa kokudla kanye nokuphrinta kwe-3D.
Oxhumana naye Wokudla uvunyelwe- I-Polylactic acid ivunyelwe njenge-polymer Eyaziwa Ngokujwayelekile Njengephephile (i-GRAS) futhi iphephile ukuthintana nokudla.
Izinzuzo zokupakishwa kokudla:
Azinawo amakhemikhali ayingozi afanayo nemikhiqizo esekwe ku-petroleum
Njengoba eqinile njengoba abaningi ezivamile plastic
Isiqandisi-siphephile
Izinkomishi zingakwazi ukumelana nezinga lokushisa elifinyelela ku-110°F (izitsha ze-PLA zingakwazi ukumelana nezinga lokushisa elifika ku-200°F)
Ayinabuthi, ayithathi hlangothi, futhi 100% ivuseleleka
Esikhathini esedlule, lapho opharetha besevisi yokudla befuna ukushintshela emaphaketheni e-eco-friendly, kungenzeka ukuthi bathole imikhiqizo ebizayo nephansi kuphela.Kodwa i-PLA iyasebenza, iyabiza, futhi iyasimama.Ukushintshela kule mikhiqizo kuyisinyathelo esibalulekile sokwehlisa izinga lekhabhoni lebhizinisi lakho lokudla.
Ngaphandle kokupakishwa kokudla, yiziphi ezinye izinto ezisetshenziselwa i-PLA?
Lapho ikhiqizwa okokuqala, i-PLA yabiza cishe u-$200 ukwenza iphawundi elilodwa.Ngenxa yezinqubo ezintsha zokukhiqiza, kubiza ngaphansi kuka-$1 ngephawundi ngalinye ukukhiqiza namuhla.Ngenxa yokuthi ayisabizi kakhulu, i-polylactic acid inamandla okutholwa okukhulu.
Ukusetshenziswa okuvame kakhulu kuhlanganisa:
I-3D printing material filament
Ukupakishwa kokudla
Ukupakisha izingubo
Ukupakisha
Kuzo zonke lezi zinhlelo zokusebenza, ezinye izindlela ze-PLA ziveza izinzuzo ezicacile kunezinto ezivamile.
Isibonelo, kumaphrinta e-3D, i-PLA filaments ingenye yezinketho ezidume kakhulu.Anendawo encibilikayo ephansi kunezinye izinketho zefilament, okwenza kube lula futhi kuphephe ukuzisebenzisa.I-PLA filament yokuphrinta ye-3D ikhipha i-lactide, ethathwa njengentuthu engenabuthi.Ngakho-ke, ngokungafani nezinye izindlela ze-filament, iphrinta ngaphandle kokukhipha ubuthi obuyingozi.
Ibuye iveze izinzuzo ezithile ezicacile emkhakheni wezokwelapha.Ithandwa ngenxa ye-biocompatibility yayo kanye nokuwohloka okuphephile njengoba imikhiqizo ye-PLA incipha ibe yi-lactic acid.Imizimba yethu ikhiqiza i-lactic acid ngokwemvelo, ngakho iyinhlanganisela ehambisanayo.Ngenxa yalokhu, i-PLA ivame ukusetshenziswa ezinhlelweni zokulethwa kwezidakamizwa, izimila zezokwelapha, kanye nobunjiniyela bezicubu.
Emhlabeni wefayibha nezindwangu, abameli bahlose ukufaka ama-polyester angavuseleleki nge-PLA fiber.Izindwangu nezindwangu ezenziwe nge-PLA fibre azisindi, ziyaphefumula, futhi ziyasebenziseka kabusha.
I-PLA isetshenziswa kakhulu embonini yokupakisha.Izinkampani ezinkulu ezifana ne-Walmart, i-Newman's Own Organics kanye ne-Wild Oats zonke seziqalile ukusebenzisa amaphakheji ahlanganiswe ne-compostable ngezizathu zemvelo.
Ingabe imikhiqizo yokupakisha ye-PLA ilungele ibhizinisi lami?
Uma amabhizinisi akho okwamanje esebenzisa noma iyiphi yalezi zinto ezilandelayo futhi unothando lokusimama nokunciphisa izinga lekhabhoni lebhizinisi lakho, khona-ke ukupakishwa kwe-PLA kuyindlela enhle kakhulu:
Izinkomishi (izinkomishi ezibandayo)
Izitsha zeDeli
Ukupakishwa kwamabhamuza
Izitsha zokudla
Utshani
Izikhwama zekhofi
Ukuze ufunde kabanzi mayelana nemikhiqizo ye-PLA ye-YITO Packaging ethengekayo futhi evumelana nemvelo, thintana!
