FILM NIKI?
Filime ya PLA ni firime ibora kandi yangiza ibidukikije ikozwe mu bigori bishingiye ku bigori bya Polylactic Acide resin.amasoko kama nka krahisi y'ibigori cyangwa ibisheke. Gukoresha umutungo wa biyomasi bituma umusaruro wa PLA utandukanye na plastiki nyinshi, zikorwa hifashishijwe ibicanwa biva mu bicanwa no kubitandukanya na peteroli.
Nubwo itandukaniro ryibikoresho fatizo, PLA irashobora kubyazwa umusaruro hakoreshejwe ibikoresho bimwe na plastiki ya peteroli, bigatuma ibikorwa bya PLA bikora neza. PLA niyakabiri ikorwa cyane na bioplastique (nyuma yubushyuhe bwa termoplastique) kandi ifite ibintu bisa na polypropilene (PP), polyethylene (PE), cyangwa polystirene (PS), kimwe no kubora ibinyabuzima.
Filime ifite ibisobanuro byiza、Imbaraga nziza、nibyiza Gukomera no gukomera. Filime zacu za PLA zemerewe gufumbira ukurikije icyemezo cya EN 13432
Filime ya PLA yerekana ko ari imwe muri firime isumba izindi mu gupakira ibintu byoroshye, kandi ubu yakoreshejwe mubipfunyika indabyo, impano, ibiryo nkumugati na biscuit, ibishyimbo bya kawa.
NI GUTE PLA YATANZWE?
PLA ni polyester (polymer irimo itsinda rya ester) ikozwe na monomer ebyiri zishoboka cyangwa kubaka inyubako: acide lactique, na lactide. Acide lactique irashobora gukorwa na fermentation ya bagiteri ya karubone ya hydrata mugihe cyagenwe. Mu nganda zingana na acide lactique, karubone ya hydrata yo guhitamo irashobora kuba ibinyamisogwe, imizi yimyumbati, cyangwa ibisheke, bigatuma inzira iramba kandi ikavugururwa.
INYUNGU ZIDUKIKIJE ZA PLA
PLA irashobora kwangirika mugihe cyifumbire mvaruganda kandi izasenyuka mugihe cyibyumweru cumi na bibiri, bigatuma ihitamo ibidukikije cyane mugihe cya plastiki bitandukanye na plastiki gakondo zishobora gufata ibinyejana kugirango zangirika bikarangira zikora microplastique.
Ibikorwa byo gukora PLA nabyo byangiza ibidukikije kuruta ibya plastiki gakondo bikozwe mubutunzi butagira ingano. Nk’uko ubushakashatsi bubyerekana, imyuka ya karubone ijyanye n’umusaruro wa PLA iri munsi ya 80% ugereranije n’iya plastiki gakondo (isoko).
PLA irashobora gusubirwamo kuko ishobora gucika kuri monomer yumwimerere hakoreshejwe uburyo bwa depolymerisation yumuriro cyangwa hydrolysis. Ibizavamo ni igisubizo cya monomer gishobora kwezwa no gukoreshwa mubikorwa bya PLA byakurikiyeho nta gutakaza ubuziranenge.
