YINTONI IFILM YEPLA?
Ifilimu ye-PLA yifilimu enokuchithwa kwezinto eziphilayo kunye nokusingqongileyo okwenziwe kwi-corn-based Polylactic Acid resin.organic sources ezifana ne-corn starch okanye iswekile.Ukusebenzisa izixhobo ze-biomass kwenza imveliso ye-PLA yahluke kwiiplastiki ezininzi, eziveliswa kusetyenziswa amafutha e-fossil ngokusebenzisa i-distillation kunye ne-polymerization ye-petroleum.
Ngaphandle kokwahluka kwempahla ekrwada, i-PLA inokuveliswa kusetyenziswa izixhobo ezifanayo neeplastiki zepetrochemical, nto leyo eyenza iinkqubo zokwenziwa kwe-PLA zibe neendleko ezifanelekileyo.I-PLA yeyesibini i-bioplastic eveliswa kakhulu (emva kwesitashi se-thermoplastic) kwaye ineempawu ezifanayo kwi-polypropylene (PP), i-polyethylene (PE), okanye i-polystyrene (PS), kunye nokuba yi-biodegradeable.
Ifilimu icace kakuhle,Amandla okuqina okuhle,kunye nokuqina okuhle kunye nokuqina.Imiboniso bhanyabhanya yethu ye-PLA iqinisekisiwe ukuba yenziwe umgquba ngokwesatifikethi se-EN 13432
Ifilimu ye-PLA ibonakalisa ukuba yenye yefilimu yokupakisha ephezulu kwimboni yokupakisha eguquguqukayo, kwaye ngoku isetyenziswe kwiiphakheji zeentyatyambo, isipho, ukutya okufana nesonka kunye nebhiskithi, iimbotyi zekofu.
IVEZWA NJANI IPLA?
I-PLA i-polyester (i-polymer equkethe iqela le-ester) eyenziwe ngee-monomers ezimbini ezinokwenzeka okanye iibhloko zokwakha: i-lactic acid, kunye ne-lactide.Iasidi yeLactic inokuveliswa ngokubiliswa kwebhaktheriya kumthombo wecarbohydrate phantsi kweemeko ezilawulwayo.Kwimveliso yemveliso ye-lactic acid, umthombo wekhabhohayidrethi okhethwayo unokuba sistatshi sombona, iingcambu zecassava, okanye ummoba, nto leyo eyenza ukuba inkqubo iqhubeke kwaye ihlaziywe.
I-ADVANTAGE YOKUSINGQONGILEYO YE-PLA
I-PLA i-biodegradable phantsi kweemeko zokurhweba komgquba kwaye iya kuphuka kwiiveki ezilishumi elinambini, iyenze ibe yinto ekhethiweyo yokusingqongileyo xa ifika kwiiplastiki ngokungafaniyo neeplastiki zendabuko ezinokuthatha iinkulungwane ukubola kwaye ekugqibeleni zenze i-microplastics.
Inkqubo yokwenziwa kwe-PLA ikwanobuhlobo ngakumbi nokusingqongileyo kuneeplastiki zemveli ezenziwe ngemithombo yefosili elinganiselweyo.Ngokophando, ukukhutshwa kwekhabhoni ehambelana nokuveliswa kwe-PLA yi-80% ephantsi kuneyeplastiki yendabuko (umthombo).
I-PLA inokuphinda isetyenziswe njengoko inokwaphulwa kwi-monomer yayo yokuqala ngenkqubo ye-thermal depolymerization okanye nge-hydrolysis.Isiphumo sisisombululo se-monomer esinokucocwa kwaye sisetyenziswe kwimveliso ye-PLA elandelayo ngaphandle kokulahlekelwa komgangatho.
