Ithini i-PLA eyonakalisayo ye-Pla Paper Cup Coffee Cup?
2022-01-22
Iyini impahla eluhlaza ye-PLA ewohlokayoI-Pla Paper Cup Coffee Cup?
I-PLA iwuhlobo olusha lwezinto eziphilayo ezisekelwe ku-bio futhi ezivuselelekayo ezibolayo, ezenziwe ngesitashi ezinsizeni zezitshalo ezivuselelekayo (njengommbila, umdumbula, njll.). Izinto ezingavuthiwe zesitashi ziyahlanjululwa ukuze kutholwe i-glucose, bese kuthi i-glucose nezinhlobo ezithile zivutshelwe ukuze kukhiqizwe i-lactic acid ephezulu, bese kuthi i-polylactic acid enesisindo esithile samangqamuzana ihlanganiswe ngendlela yokuhlanganisa amakhemikhali.

I-PLA inokubola okuhle kwe-biodegradability. Ngemuva kokusetshenziswa, kungonakalisa ngokuphelele ama-microorganisms emvelweni ngaphansi kwezimo ezithile, futhi ekugcineni kukhiqize i-carbon dioxide namanzi, engangcolisi imvelo. Kuzuzisa kakhulu ukuvikela imvelo futhi kuqashelwa njengento ehambisana nemveloIzitsha ze-Biodegradable.
Kuyisinqumo esihle ukwenza i-Kraft Yekhwalithi Ephezulu Isitsha se-Pla Paper Salad Esilahlwayo futhiI-Paper Cup Pla.
I-PLA inokuqina okuhle kwe-thermal, izinga lokushisa lokucubungula i-170 ~ 230 ℃, nokumelana okuhle kwe-solvent. Inkomishi yephepha eboshiwe nesembozo senkomishi eyenziwe nge-polylactic acid inokuvumelana okuhle kwe-biocompatibility, isicwebezelisi, obala, isibambo nokumelana nokushisa, kanye nokumelana okuthile namabhaktheriya, ukubambezeleka komlilo kanye nokumelana ne-UV.
