Ithini ifilimu?
Ifilimu ye-plate yifilimu enokubekwa yi-biode kunye nendawo okusingqongileyo eyenziwe kwi-colllactic acid. Sebenzisa izixhobo ze-biomass kwenza ukuveliswa kweplani eyahlukileyo kwiiplasitiki ezininzi, eziveliswa usebenzisa ifossil fuels kwi-distillation kunye ne-polymerization yepetroleum.
Ngaphandle komehluko wezinto eziluhlaza okuphezulu, i-Plat inokuveliswa zisebenzisa izixhobo ezifanayo njengeplastiki zeplastiki, ukwenza iinkqubo zokwenza iinkqubo ze-plate zokwenza iindleko zisebenza ngokufanelekileyo. Iplagi yeyona biphastistik yesibini evelisiweyo (emva kwesitatshiistic) kwaye ineempawu ezifanayo kwiPolypropylene (PP), iPolythylene (PE), kunye nePolystrene (PS) kunye ne-biededdeed.
Ifilimu inolwazi oluhle,Amandla amahle,kunye nokuqina okufanelekileyo kunye nobunzima.Obles Plams uqinisekisiwe ukuba uqinisekisiwe ngokwesiqinisekiso se-13432 isiqinisekiso
Ifilimu ingqina ukuba yenye yefilimu ebalaseleyo kwishishini lokupakisha, kwaye ngoku isetyenzisiwe kwiipakethi zentyatyambo, isipho, ukutya, iimbotyi zekofu, iimbotyi zekofu, iimbotyi zekofu.
Iveliswa njani iplani?
Iplagi (ipolymer enamaqela e-Ester) eyenziwe nge-monomers ezimbini okanye iibhloko zokwakha: i-lactic acid, kunye ne-lactive. I-lactic acid inokuveliswa yintsholongwane yomthombo we-carbohydrate phantsi kweemeko ezilawulwayo. Kwimveliso yamanqanaba emizi-mveliso ye-lactic acid, umthombo wokhetho olwekhethwayo unokusitayela yengqolowa, iingcambu zecassava, okanye iswekile, eyenza ukuba inkqubo zizinzile kwaye ihlaziywe.
Inzuzo yendalo
I-Plais yi-biodegraded phantsi kwemeko yezorhwebo yentengiso kwaye iya kuqhekezwa kwiiveki ezilishumi elinambini, iyenza ukuba ibe yindawo ekhethwa kuyo kwiplastiki ngokwahlukileyo kwiiplasitiki zemveli ezinokuthatha iinkulungwane zokubola kwaye ziphelise imicroplastics.
Inkqubo yokwenziwa kweplathi inobuhlobo ngakumbi kunolo lweeplastiki zemveli ezenziwe ngemithombo yeefosili zefonili. Ngokutsho koPhando, ukuphuma kwekhabhoni ehambelana ne-plare ye-8 8% isezantsi kuneso seplastiki yemveli (umthombo).
Iplani inokuphinda isetyenziselwe ukuphinda isebenze njengoko inokutyhobozela kwi-monomer yayo yoqobo ngenkqubo ye-thermal depolyrization okanye yi-hydrolysis. Isiphumo sisisombululo esinemikhono esinokuhlanjululwa kwaye sisetyenziselwe ukuveliswa kwe-plas elandelayo ngaphandle kokuphulukana nomgangatho.
