Idizayini, indlela yokuphila, kanye nokusebenza kuyisimo sokunquma esimaphakathi sokuthengwa kwezimpahla zemidlalo nezinsiza. Kule makethe echumayo, imikhiqizo eminingi ithunyelwa isuka e-Asia iye e-Europe, engasimeme emvelweni. Abacwaningi eFraunhofer Institute for Chemical Technology ICT benze enye indlela.
Idizayini yomkhiqizo wezigqoko zamabhayisikili ibeka ngokufanelekile ukusebenza phambili. Kodwa-ke, lokhu kuze kube manje kube ngezindleko zokujikeleza, okushiya indawo ebalulekile yemvelo-ikakhulukazi lapho izigqoko zekhanda zenziwa e-Asia kusukela kumapulasitiki asekelwe ngophethiloli akhiqizwa ngobuningi: igobolondo lesigqoko lenziwe nge-polycarbonate (PC), umgogodla wegwebu. ye-polystyrene foam (EPS), izingxenye ngokuvamile ze-polypropylene (PP), kanye nezintambo zenayiloni (PA). Ukwakhiwa okunjalo kuvame ukwenza ukugaywa kabusha kwezinto kukho kokubili ngokobuchwepheshe nangokwezomnotho kungenzeki ekupheleni kwempilo yomkhiqizo. Ngenxa yalokho, izigqoko zokuzivikela zivame ukushiswa ngemva kweminyaka emithathu kuya kwemihlanu yokusetshenziswa.
Imikhiqizo eyenziwe nge-mono-materials ivikela imvelo
Uma ubuza umgomo wokwenza ingxenye ngayinye kusuka kokuhloselwe yona ngokuqondile, izindlela ezintsha zokukhiqiza eziqhubekayo ziyavela. Enye indlela enjalo iboniswa iphrojekthi ye-PIMMS, exhaswe yiFraunhofer Future Foundation. Ngaphakathi kohlaka lwayo, kuye kwathuthukiswa izihloko zezemidlalo ezihlukahlukene, ezihlanganisa indaba eyodwa kuphela. Ngokusho kososayensi, i-PLA esekelwe ku-bio kanye neyindilinga ifaneleka ngokukhethekile. Ngenxa yezakhiwo zayo zobuchwepheshe kanye nentengo yokuncintisana, isungulwe emakethe iminyaka eminingana. Uma kuqhathaniswa nezinto ezisetshenziswayo kuze kube manje, i-PLA inonyawo olubonakalayo olufika ngokuphindwe kasishiyagalombili ukuncane.
Umakalabha webhayisikili uyaqhudelana
Isigqoko sokuzivikela sebhayisikili sisebenza njengesibonisi sezinto ezintsha kanye nomqondo wokuklama, njengoba kufanele siqinisekise ukusebenza okuphezulu, ikakhulukazi ukumunca amandla aphezulu ngesisindo esincane. Okunye okubalulekile empumelelweni yemakethe ukugqoka ukunethezeka, intengo, nokubukeka.
Njengengxenye yephrojekthi yonyaka owodwa nesigamu egxile ezimakethe, i-Fraunhofer ICT, ngokubambisana nezinkampani ezihlukene zezimboni (i-Comfil ApS, i-Elas A/S, i-WSVK, i-Polola SAS), ithuthukise amagwebu ayizinhlayiyana, amafilimu e-thermoforming, imicu. , kanye nezinhlanganisela ezenziwe ngokuphelele nge-PLA. Ukukhiqizwa nokucutshungulwa kwazo kudinga ukulawulwa kwenqubo okunembe futhi okufanelana nomuntu ngamunye. Ngenxa yokubambisana okubanzi, isigqoko sokuzivikela se-PLA singenziwa ngendlela efanayo nenamandla okukhiqiza ngobuningi njengesigqoko esivamile samabhayisikili esisekelwe ku-petroleum. Lokhu kubeka isisekelo sokwethulwa kwezimakethe ezincintisanayo zezigqoko zokuzivikela ezintsha.
Ukumelana kwezinto kumathonya avamile emvelo ngesikhathi sokusetshenziswa sekuhloliwe kakade kahle. Ukuhlola kwangaphandle okuthobelana okujwayelekile, okuhloselwe ukufakazela ukusebenziseka kwesigqoko, kusalindiwe. Ukuhlaziywa kwe-lifecycle (LCA) kuzophinda kulinganise i-CO2 footprint ethuthukisiwe yesigqoko sokuzivikela sebhayisikili ye-mono-material ekwazi ukugaywa kabusha ngokuqhathaniswa nomklamo osuselwe ku-petroleum kukho konke ukukhiqiza, ukusetshenziswa, kanye nokuphela kokuphila.
Isikhathi sokuthumela: Jan-10-2025
