Izindwangu ezenziwe ngosilika-ezifana nokucwebezela nokuzwakala. , Ungasishukumisi isikhumba, sikhululekile empilweni yomuntu, sikhululekile ukugqoka, kulungele ikakhulukazi izingubo zangaphansi nezemidlalo
Eminyakeni yamuva nje ama-biomaterials afana ne-PLA angene embonini yokupakisha ngamandla amakhulu. Aba amafilimu anikeza izixazululo ezivumelana nemvelo. Amafilimu enziwe ngalezi zinhlobo zama-biomaterial abethuthukisa ukubonakala kwawo nokusebenza ngokumelene nezidingo zokupakishwa okujwayelekile.
Amafilimu azoguqulwa abe amaphakheji ngokuvamile kufanele afakwe i-laminated ukuze athole ukupakishwa okuvikeleke kakhulu nokuphakeme okuvimbayo ngaleyo ndlela kuvikelwe kangcono umkhiqizo ongaphakathi.
I-Polylactic acid (PLA EF UL) isetshenziselwa ukwakhiwa kwama-laminates azo zonke izinhlobo zezicelo: amafasitela ezikhwameni zesinkwa, amafasitela amabhokisi amakhadibhodi, ama-doypacks ekhofi, ama-pizza seasonings nge-Kraft paper noma ama-stickpacks emigoqo yamandla, phakathi kwabanye abaningi.
Izinto ezibonakalayo ze-PLA ziyenza ifaneleke ukwakhiwa kwefilimu yepulasitiki, amabhodlela kanye nemishini yezokwelapha engaboli, okuhlanganisa nezikulufu, izikhonkwane, amapuleti nezinduku eziklanyelwe ukuwohloka kwemvelo phakathi kwezinyanga eziyisi-6 kuya kweziyi-12). I-PLA ingasetshenziswa njengento yokugoqa njengoba ibopha ngaphansi kokushisa.
I-PLA ihlukaniswa njengepulasitiki engu-100% enemithombo yemvelo: yenziwe ngezinto ezivuselelekayo ezifana nommbila noma umoba. I-lactic acid, etholakala ngokuvubela ushukela noma isitashi, bese iguqulwa ibe i-monomer ebizwa ngokuthi i-lactide. Le lactide ibe seyenziwe i-polymerised ukuze ikhiqize i-PLA.I-PLA nayo iyakwazi ukubola ngoba ingafakwa umquba.
Ifilimu ye-Coextruding ye-PLA inezinzuzo eziningana. Ngomongo wohlobo lwe-PLA olumelana nokushisa okuphezulu kanye nesikhumba esiphansi lokushisa, ivumela iwindi lokucubungula elibanzi ezinhlelweni eziningi, kuyilapho igcina ubuqotho besakhiwo obuningi kakhulu ezimweni zokushisa okuphezulu. I-Coextruding iphinde ivumele izithasiselo ezincane, ezigcina ukucaca nokubukeka okungcono.
Ngenxa yenqubo yayo eyingqayizivele, amafilimu e-PLA amelana nokushisa ngendlela engavamile. Ngokushintsha kwe-dimensional okuncane noma okungenakho ngamazinga okushisa okucubungula angu-60°C (kanye noshintsho oluncane olungaphansi kuka-5% ngisho naku-100°C imizuzu emi-5).
Ngoba isebenzisa amandla amancane ukukhiqiza ama-pellets e-PLA. Kufika ku-65% ngaphansi kukaphethiloli wezinsalela kanye nokukhishwa kwegesi ebamba ukushisa ngo-65% kunalapho kwenziwa ipulasitiki yendabuko.
Ipulasitiki ye-PLA inikeza izinketho eziningi zokuphela kwempilo kunanoma iyiphi enye impahla. Ingagaywa kabusha ngokomzimba, ifakwe umquba ezimbonini, ishiswe, ifakwe endaweni yokulahla imfucumfucu futhi iphinde isetshenziswe kabusha ibuyiselwe esimweni sayo se-lactic acid.
Yebo. Ukuze ucele isampula, vakashela isigaba sethu esithi "Thintana nathi" futhi uhambise isicelo sakho nge-imeyili.
