IYINI Ifilimu ye-PLA?
Ifilimu ye-PLA iyifilimu ebolayo futhi evumelana nemvelo eyenziwe ngommbila we-Polylactic Acid resin.imithombo ephilayo efana nesitashi sombila noma umoba.Ukusebenzisa izinsiza ze-biomass kwenza ukukhiqizwa kwe-PLA kuhluke kumapulasitiki amaningi, akhiqizwa kusetshenziswa uphethiloli we-fossil ngokusebenzisa i-distillation kanye ne-polymerization ye-petroleum.
Ngaphandle komehluko wempahla eluhlaza, i-PLA ingakhiqizwa kusetshenziswa okokusebenza okufanayo namapulasitiki e-petrochemical, okwenza izinqubo zokukhiqiza ze-PLA zibe nezindleko eziphansi.I-PLA ingeyesibili i-bioplastic ekhiqizwa kakhulu (emva kwesitashi se-thermoplastic) futhi inezici ezifanayo ne-polypropylene (PP), i-polyethylene (PE), noma i-polystyrene (PS), kanye nokuba yi-biodegradeable.
Ifilimu inokucaca Okuhle,Amandla amahle okuqina,kanye nokuqina okuhle nokuqina.Amafilimu ethu e-PLA agunyazwe ukufakwa komquba ngokwesitifiketi se-EN 13432
Ifilimu ye-PLA ifakazela ukuthi ingenye yefilimu yokupakisha ephakeme kakhulu embonini yokupakisha eguquguqukayo, futhi manje isetshenziswe kumaphakheji wembali, isipho, ukudla okufana nesinkwa namabhisikidi, ubhontshisi wekhofi.
IKHISHWA KANJANI I-PLA?
I-PLA iyi-polyester (i-polymer equkethe iqembu le-ester) eyenziwe ngama-monomers amabili okungenzeka noma amabhlogo wokwakha: i-lactic acid, ne-lactide.I-lactic acid ingakhiqizwa ukuvutshelwa kwebhaktheriya komthombo wamacarbohydrate ngaphansi kwezimo ezilawulwayo.Ekukhiqizweni kwezimboni ze-lactic acid, umthombo wama-carbohydrate ongawukhetha kungaba isitashi sombila, izimpande zomdumbula, noma umoba, okwenza inqubo isimeme futhi ivuseleleke.
I-ADVANTAGE YEMVELO YE-PLA
I-PLA iyakwazi ukubola ngaphansi kwezimo ze-composting yezentengiselwano futhi izophuka emasontweni ayishumi nambili, okwenza kube ukukhetha okungokwemvelo uma kuziwa kumapulasitiki ngokungafani namapulasitiki endabuko angathatha amakhulu eminyaka ukubola futhi agcine edala ama-microplastics.
Inqubo yokukhiqiza ye-PLA ibuye ihambisane nemvelo kakhulu kunaleyo yamapulasitiki endabuko enziwe ngezinsalela zezinto ezimbiwa phansi ezinomkhawulo.Ngokocwaningo, ukukhishwa kwekhabhoni okuhlotshaniswa nokukhiqizwa kwe-PLA kuphansi ngo-80% kunepulasitiki yendabuko (umthombo).
I-PLA ingaphinda igaywe kabusha njengoba ingahlukaniswa ibe yi-monomer yayo yangempela ngenqubo ye-thermal depolymerization noma nge-hydrolysis.Umphumela uyisixazululo se-monomer esingahlanzwa futhi sisetshenziselwe ukukhiqizwa kwe-PLA okulandelayo ngaphandle kokulahlekelwa kwekhwalithi.
