Yintoni i-PLA?Yonke into ekufuneka uyazi
Ngaba ukhe wakhangela enye indlela kwiiplastiki ezisekwe kwipetroleum kunye nokupakishwa?Imakethi yanamhlanje iya ngokuya isiya kwimveliso enokubola kunye ne-eco-friendly eyenziwe ngezixhobo ezivuselelekayo.
Ifilimu ye-PLAIimveliso ziye zakhawuleza ukuba zezinye zezona zithandwa kakhulu ezinokubola kunye nokukhethwa kokusingqongileyo kwimarike.Uphononongo luka-2017 lwafumanisa ukuba ukutshintshwa kweplastiki esekwe kwipetroleum kunye neeplastiki ezisekwe kwibhayoloji kunokunciphisa ukukhutshwa kwerhasi yobushushu bemizi-mveliso ngama-25%.
Yintoni i-PLA?
I-PLA, okanye i-polylactic acid, iveliswa kuyo nayiphi na iswekile evundileyo.Uninzi lwe-PLA lwenziwa ngombona kuba umbona yenye yezona swekile zingabizi kakhulu kwaye zifumaneka kwihlabathi jikelele.Noko ke, ummoba, ingcambu yetapioca, icassava, neswekile beet pulp zezinye iindlela.
Njengezinto ezininzi ezinxulumene ne-chemistry, inkqubo yokudala i-PLA kumbona inzima kakhulu.Nangona kunjalo, inokuchazwa ngamanyathelo ambalwa acacileyo.
Zenziwa njani iimveliso ze-PLA?
Amanyathelo asisiseko okudala i-polylactic acid evela kumbona zezi zilandelayo:
1. Isitatshi sokuqala sombona kufuneka sitshintshwe sibe yiswekile ngenkqubo yomatshini ebizwa ngokuba yi-wet milling.Ukusila okumanzi kwahlula isitatshi kwiinkozo.I-Acid okanye ii-enzymes zongezwa emva kokuba la malungu ahluliwe.Emva koko, bayafudumala ukuguqula isitashi kwi-dextrose (i-sugar sugar).
2. Emva koko, i-dextrose ivundisiwe.Enye yeendlela eziqhelekileyo zokuvutshelwa ziquka ukongeza ibhaktheriya yeLactobacillus kwi-dextrose.Oku, kwakhona, kudala i-lactic acid.
3. I-asidi ye-lactic emva koko iguqulwa ibe yi-lactide, i-ring-form dimer ye-lactic acid.Ezi molekyuli ze-lactide zidibana kunye ukuze zenze iipholima.
4. Isiphumo se-polymerization ngamaqhekeza amancinci eplastiki ye-polylactic acid ekrwada enokuthi iguqulwe ibe yimveliso yeplastiki ye-PLA.
Ziziphi iingenelo zeemveliso ze-PLA?
I-PLA idinga i-65% yamandla angaphantsi kwamandla ukuvelisa kuneeplastiki zemveli, ezisekelwe kwipetroleum.Ikwakhupha i-68% yeegesi ze-greenhouse ezimbalwa.Kwaye akuphelelanga apho:
Iinzuzo zokusingqongileyo:
Xa kuthelekiswa neeplastiki ze-PET - Ngaphezu kwe-95% yeeplastiki zehlabathi zenziwe ngegesi yendalo okanye i-oyile ekrwada.Iiplastiki zefosili azikho yingozi kuphela;zikwasisixhobo esinesiphelo.Iimveliso ze-PLA zibonakalisa ukutshintshwa okusebenzayo, okunokuhlaziywa, kunye nokuthelekiseka.
I-Bio-based– Izinto zemveliso esekwe kwibhayoloji zithathwe kulimo oluhlaziyekayo okanye kwizityalo.Ngenxa yokuba zonke iimveliso ze-PLA zivela kwi-starches yeswekile, i-polylactic acid ithathwa njenge-bio-based.
I-Biodegradable-Iimveliso ze-PLA zifikelela kwimigangatho yamazwe ngamazwe yokuthotywa kwebhayoloji, zithomalalisa ngokwendalo kunokuba zifumbe kwiindawo zokulahla inkunkuma.Ifuna iimeko ezithile ukuthotywa ngokukhawuleza.Kwindawo yokwenziwa komgquba kwimizi-mveliso, inokwaphuka kwiintsuku ezingama-45-90.
Ayikhuphi umsi oyityhefu – Ngokungafaniyo nezinye iiplastiki, iiplastiki zebhayoloji azikhuphi nawuphi na umsi oyityhefu xa zitshisiwe.
Thermoplastic-I-PLA yi-thermoplastic, ngoko ke iyabumbeka kwaye iyabunjwa xa ishushu kwiqondo lobushushu lokunyibilika kwayo.Inokuqiniswa kwaye ifakwe isitofu kwiifomu ezahlukeneyo iyenza ibe lukhetho olukhulu lokupakishwa kokutya kunye noshicilelo lwe-3D.
Ukutya Uqhagamshelwano-luvunyiwe-Iasidi yePolylactic yamkelwe njengePolymer Jikelele eyaziwa njengeKhuselekileyo (GRAS) kwaye ikhuselekile kuqhagamshelwano lokutya.
Iinzuzo zokupakishwa kokutya:
Abanayo imichiza eyingozi efanayo njengemveliso esekwe kwipetroleum
Zinamandla njengeeplastiki ezininzi eziqhelekileyo
Isikhenkcisi-sikhuselekile
Iikomityi ziyakwazi ukumelana namaqondo obushushu ukuya kuthi ga kwi-110°F (Iimpahla ze-PLA ziyakwazi ukumelana namaqondo obushushu ukuya kutsho kuma-200°F)
I-non-toxic, i-carbon-neutral, kunye ne-100% ehlaziyiweyo
Ngaphambili, xa abaqhubi benkonzo yokutya babefuna ukutshintshela kwi-eco-friendly packaging, basenokuba bafumana kuphela iimveliso ezibizayo kunye ne-subpar.Kodwa i-PLA iyasebenza, iyabiza, kwaye izinzileyo.Ukutshintshela kwezi mveliso linyathelo elibalulekileyo lokunciphisa icarbon footprint yeshishini lakho lokutya.
Ngaphandle kokupakishwa kokutya, zeziphi ezinye izinto ezisetyenziselwa iPLA?
Xa yaveliswa okokuqala, iPLA yaxabisa malunga nama-200 eerandi ukwenza iponti enye.Ngombulelo kwizinto ezintsha kwiinkqubo zokuvelisa, kubiza ngaphantsi kwe-1 yeedola ngeponti ukuvelisa namhlanje.Ngenxa yokuba ayisabizi ndleko, iasidi yepolylactic inokubanakho ukwamkelwa okukhulu.
Olona setyenziso luxhaphakileyo lubandakanya:
I-3D yoshicilelo lwefilament
Ukupakishwa kokutya
Ukupakishwa kwempahla
Ukupakishwa
Kuzo zonke ezi zicelo, iindlela ezizezinye ze-PLA zibonakalisa iingenelo ezicacileyo ngaphezu kwezinto zemveli.
Umzekelo, kwiiprinta ze-3D, i-PLA filaments yenye yezona zinto zikhethwa kakhulu.Banendawo esezantsi yokunyibilika kunezinye iinketho zefilament, ezenza kube lula kwaye kukhuseleke ukuzisebenzisa.I-3D yoshicilelo lwe-PLA filament ikhupha i-lactide, ethathwa ngokuba ngumsi ongeyotyhefu.Ke, ngokungafaniyo nezinye iindlela zefilament, iprinta ngaphandle kokukhupha nayiphi na ityhefu eyingozi.
Ikwabonisa iingenelo ezithile ezicacileyo kwinkalo yezonyango.Iyathandwa ngenxa ye-biocompatibility yayo kunye nokuthotywa okukhuselekileyo njengoko iimveliso ze-PLA zisihla zibe yi-lactic acid.Imizimba yethu ivelisa iasidi ye-lactic ngokwemvelo, ngoko yinto ehambelanayo.Ngenxa yoku, i-PLA isetyenziswa rhoqo kwiinkqubo zokuhanjiswa kweziyobisi, ukufakelwa kwezonyango, kunye nobunjineli bezicubu.
Kwilizwe lefayibha kunye nelaphu, abameli bajolise ekutshintsheni iipolyester ezingahlaziyekiyo nge-PLA fiber.Amalaphu kunye namalaphu enziwe ngePLA fiber alula, ayaphefumla, kwaye anokuphinda asetyenziswe.
I-PLA isetyenziswa kakhulu kwishishini lokupakisha.Iinkampani ezinkulu ezinje ngeWalmart, iNewman's Own Organics kunye neWild Oats zonke sele ziqalisile ukusebenzisa ukupakishwa okuvundisiweyo ngenxa yezizathu zokusingqongileyo.
Ngaba iimveliso zokupakisha ze-PLA zilungile kwishishini lam?
Ukuba amashishini akho ngoku asebenzisa nayiphi na kwezi zinto zilandelayo kwaye unomdla wozinzo kunye nokunciphisa indawo yekhabhoni yeshishini lakho, ke ukupakishwa kwe-PLA lolona khetho lubalaseleyo:
Iikomityi (iikomityi ezibandayo)
Izikhongozeli zeDeli
Ukupakishwa kwamadyungudyungu
Iziqulathi zokutya
Iindiza
Iibhegi zekofu
