Umhlahlandlela we-PLA - Polylactic acid

Yini PLA? Konke odinga ukukwazi

Ubukade usesesha enye indlela yokufakelwa kwe-petroleum esuselwa ku-petroleum kanye nokupakishwa? Imakethe yanamuhla iya ngokuya iqhubekela emikhiqizweni engathandeki futhi e-eco-friendly eyenziwe ngemithombo evuselelekayo.

Ifilimu ye-PLAImikhiqizo isibe ngesinye isikhathi sibe ngenye yezinketho ezithandwa kakhulu ze-biodegradable nemvelo emakethe. Ucwaningo lwe-2017 lutholakele ukubuyisa amapulasitiki asuselwa ku-petroleum ngamapulasitiki asuselwa kwi-bio anganciphisa ukuphuma kwamagesi ezimbonini ngo-25%.

Yini PLA?

I-PLA, noma i-polylactic acid, ikhiqizwa kunoma yiluphi ushukela oluvuthayo. Iningi le-PLA lenziwe ngo-corn ngoba ummbila ungomunye woshukela oshibhile futhi otholakala emhlabeni jikelele. Kodwa-ke, umoba, impande ye-tapioca, i-cassava, kanye noshukela we-beet pulp ezinye izinketho.

Njengezinto eziningi ezihlobene ne-chemistry, inqubo yokwakha i-PLA e-Corn iyinkimbinkimbi impela. Kodwa-ke, ingachazwa ngezinyathelo ezimbalwa eziqondile.

Kwenziwa kanjani imikhiqizo ye-PLA?

Izinyathelo eziyisisekelo zokwakha i-polylactic acid kusuka kuMorn zimi ngokulandelayo:

1. Isitashi sokuqala sommbila kufanele siguqulwe sibe ushukela ngenqubo yokwenza imishini ebizwa ngokuthi i-Wet Milling. I-WET milling ihlukanisa isitashi esikhwameni. I-acid noma ama-enzyme angeziwe uma lezi zingxenye zihlukaniswe. Ngemuva kwalokho, bafudumele ukuguqula isitashi babe yi-dextrose (Aka ushukela).

2. Okulandelayo, i-dextrose ibilisiwe. Enye yezindlela ezivame kakhulu ukuvutshelwa zifaka ukungeza amagciwane e-lactobacillus kwi-dextrose. Lokhu, nakho, kwakha i-lactic acid.

3. I-lactic acid iguqulwe ibe yi-leactide, i-ring-form dimmer ye-lactic acid. Lawa ma-molecule we-lactide molecule ahlangana ndawonye ukudala ama-polymers.

4. Umphumela we-polymerization yingcezu emincane yepulasitiki eluhlaza ebonakalayo ye-polylactic acid engaguqulwa ibe yimikhiqizo yepulasitiki ye-PLA.

Yiziphi izinzuzo zemikhiqizo ye-PLA?

I-PLA idinga amandla amancane angama-65% ukukhiqiza kunamapulasithi endabuko, asuselwa ku-petroleum. Iphinde ikhiphe amagesi angama-68% ambalwa abamba ukushisa. Futhi akupheleli:

Izinzuzo zezemvelo:

Ngokuqhathaniswa nePet Plastics - Bangaphezu kwama-95% amapulasitiki emhlabeni adalwe kusuka kugesi yemvelo noma uwoyela ongahluziwe. Amapulasitiki asuselwa ku-fossil amafutha awayona ingozi kuphela; Futhi zingumthombo oqondile. Imikhiqizo ye-PLA iletha ukushintshwa okusebenzayo, okuvuselelekayo, nokuqhathaniswa.

I-Bio-based- Izinto zomkhiqizo ezenzelwe i-Bio zitholakala kwezolimo ezivuselelekayo noma ezitshalweni. Ngoba yonke imikhiqizo ye-PLA ivela ezinkingeni zikashukela, i-polylactic acid ibhekwa njenge-bio-based.

Biodegradable- Imikhiqizo ye-PLA ifinyelela amazinga aphesheya we-biodeGradation, okuwohloka ngokwemvelo kunokuba aqhamuke ekutholeni komhlaba. Kudinga ukuthi izimo ezithile zinciphise ngokushesha. Esikhungweni somquba wezimboni, kungahle kwehle ngezinsuku ezingama-45-90.

Ayikhiphi intuthu enobuthi - ngokungafani namanye amapulasitiki, ama-bioplastics awakhiphi noma yimuphi umucu onobuthi lapho efakiwe.

I-Thermoplastic- I-PLA yi-thermoplastic, ngakho-ke iyabumba futhi iyasebenziseka lapho ifudunyezwa ekushiseni kwayo kokuncibilika. Ingaqiniswa futhi ihlanganiswe - ibumbe ngezindlela ezahlukahlukene okwenza kube inketho enkulu yokupakishwa kokudla kanye nokuphrinta kwe-3D.

Ukudla okutholwayo - kuvunyelwe- I-Polylactic acid ivunyelwe njengokwamukelwa ngokuvamile njenge-polymer ephephile (gras) polymer futhi iphephile ngokuxhumana kokudla.

Izinzuzo Zokupakisha Zokudla:

Abanalo ukwakheka okufanayo kwamakhemikhali anengozi njengemikhiqizo esekwe ku-petroleum

Aqine amapulasitiki amaningi ajwayelekile

I-Freezer-Safe

Izindebe zingaphatha amazinga okushisa afinyelela ku-110 ° F (PLA UTESILS angaphatha amazinga okushisa aze afike ku-200 ° F)

Okungenzi okunobuthi, i-carbon-hlangothi, futhi kuvuseleleke ngo-100%

Esikhathini esedlule, lapho abasebenza ngokudla kwaservice babefuna ukushintshela ekupakisheni kahle kwe-eco-friendly, kungenzeka bathola kuphela imikhiqizo ebizayo neyababilayo. Kepha i-PLA iyasebenza, iyabiza kakhulu, futhi ihlala isikhathi eside. Ukwenza ukushintshwa kwale mikhiqizo kuyisinyathelo esibalulekile ekunciphiseni i-carbon yonyawo lwebhizinisi lakho lokudla.

Ngaphandle kokupakishwa kokudla, yini okunye ukusetshenziswa kwe-pla?

Lapho kukhiqizwa okokuqala, i-PLA ibiza cishe ama- $ 200 ukwenza iphawundi elilodwa. Ngenxa yokwakhiwa kwezinqubo zokukhiqiza, kubiza imali engaphansi kwe- $ 1 ngephawundi ngalinye ukwenza namuhla. Ngoba akusabizi kakhulu, i-polylactic acid inamandla okutholwa okukhulu.

Ukusetshenziswa okuvame kakhulu kufaka phakathi:

I-3D yokuphrinta yokuphrinta ingoma

Ukupakishwa kokudla

Ukupakishwa kwezingubo

Ukuwowapha

Kuzo zonke lezi zinhlelo zokusebenza, izindlela ze-PLA ezinye izindlela ziveza izinzuzo ezicacile ngaphezulu kwezinto zendabuko.

Isibonelo, kubaphrinta we-3D, ama-pla ficaments angenye yezinketho ezithandwa kakhulu. Banendawo ephansi yokuncibilika kunezinye izinketho ze-filament, okwenza kube lula futhi kuphephe ukukusebenzisa. I-3D yokuphrinta Pla Pla Filament ikhipha i-lactide, ebhekwa njengento engeyona enobuthi. Ngakho-ke, ngokungafani nezinye izindlela zokulindisa, kunyathelisa ngaphandle kokukhipha noma yiliphi ubuthi obulimazayo.

Iphinde iveze izinzuzo ezithile ezicacile emkhakheni wezokwelapha. Kuyathandeka ngenxa yokuncipha kwayo nokuwohloka okuphephile njengemikhiqizo ye-PLA ilulaza kwi-lactic acid. Imizimba yethu ngokwemvelo ikhiqiza i-lactic acid, ngakho-ke iyindawo ehambisanayo. Ngenxa yalokhu, i-PLA isetshenziswa kaningi ezinhlelweni zokulethwa kwezidakamizwa, izimilo zezokwelapha, kanye nobunjiniyela bezicubu.

Emhlabeni we-fiber kanye nendwangu, abameli bahlose ukufaka esikhundleni ama-polyester angabonakali nge-pla fiber. Izindwangu nezindwangu ezenziwe nge-pla fiber zingasindi, ziphefumula futhi ziphinde zisebenze.

I-PLA isetshenziswa kabanzi embonini yokufaka. Izinkampani ezinkulu ezinjenge-walmart, ama-organics aseNewman uqobo kanye nama-oats asendle aqalile ukusebenzisa ukufakwa okukhohlisayo kwezizathu zezemvelo.

Umhlahlandlela we-PLA

Ingabe imikhiqizo yokupakisha ye-PLA ilungele ibhizinisi lami?

Uma amabhizinisi akho njengamanje esebenzisa noma yiziphi izinto ezilandelayo futhi uthanda ukusimama futhi wehlisa i-Carbon Footprint ye-Carbon yakho, khona-ke ukupakishwa kwe-PLA kuyindlela enhle kakhulu:

Izinkomishi (izinkomishi ezibandayo)

Iziqukathi ze-Deli

Ukubekwa kwe-blister

Ukudla okukhona

Amatata

Izikhwama zekhofi

Ukuze ufunde kabanzi nge-Pla imikhiqizo ye-PLA efinyeleleka kalula ye-Yito evumelana nemvelo, thintana!
