Anto ray biodegradable ya plastic bag?
Saray biodegradable ya plastic bag et ag makaderal ed kaliberliber ya plastic bag ya naderal ed danum tan carbon dioxide panamegley na microbial action ed kondisyon na panag-compost, ya ag pansengegan na samal ed dalin odino segundaryon polusyon. Saray kaslakan ya uusaren ed panaggawa et kaiba so:
PBAT (polybutylene adipate/terephthalate), PLA (polylactic acid), PCL (polycaprolactone), PHA (polyhydroxyalkanoate), tan arum niran biodegradable ya polimer.
Antoy kondisyon ya nabubulok iray biodegradable bag? Anto ray kondisyon parad inkaderal?
Say inkabulok ed silong na kondisyon na panag-compost
Kondisyon na panag-compost: Say danum ya onsulok ed 95%, dalin, temperatura (28-58 degree), tan espisipikon mikroorganismo.
Anto ray semi-degradable ya plastic bag?
Saray materyales ya naderal labat ed melag iran piraso tan ag nayarin magmaliw ya danum tan carbon dioxide diad loob na aturon panaon. Saray materyales ya nabulok ed liwawa (singa say d2W tan P-Life) et mangaarum na 1-2% na photooxidative agent ed tradisyonal iran materyales na PE. Wala met iray nanlaok a materyales na PE tan starch, ya say parte na starch et nayarin naderal, balet say nakekeraan ya parte na PE et ag nayarin naderal.
Antoy proporsyon na biodegradable ya plastic bag?
Base ed EU tan saray estandarte na bansa, masulok ya 90% na saray kabiangan na resin et kaukolan ya na-biodegrade pian magmaliw ya danum tan carbon dioxide
Antoy pandumaan na biodegradable bag tan ordinaryon plastic bag? Panon ya nabidbir?
Nilikud ed panag-compost, wala ray onggendan ya paraan na maples ya pakabidbiran:
Infrared spectroscopy (panangikompara ed saray istruktura na molekula) pian maples ya nabirbir so komposisyon na saray plastic bag
Chemical pyrolysis (saray materyales ya nabulok et maples ya nabulok no ambetel so alkaline iran kondisyon, bangbalet saray ordinaryon plastic bag et ag)
Antoy karukey na bilay na saray biodegradable bag?
12 bulan ed selyadon kondisyon (protektado ed danum, dalin, liwawa, tan arum ni)
Anto so PLA tan anto so PBAT?
Say PLA et sakey a polymer ya ginawa diad panguman ed starch ya magmaliw ya lactic acid monomers panamegley na fermentation, ya insan na-polymerize ed polylactic acid.
Say PBAT et sakey a polimer ya ginawa panamegley na kemikal ya panag-polymerize na adipic acid, terephthalic acid, tan butanediol.
Parehon nayarin nabulok irayan materyales pian magmaliw ya danum tan carbon dioxide no man-compost.
Akin et iyarum so PBAT?
Say PBAT et walaan na ekselentin inka-flexible, processability, tan resistensya ed atagey tan abeban temperatura, ya makapenek ed saray pankaukolan na saray aplikasyon na pelikula. Niarum ni, say PBAT et malaknab ya naala, mainomay ya gawaen a dakel, tan abeba so gastos, kanian sakey itan ya ekselentin produkto ya isalet ed saray materyales ya polyolefin.
