I-Polylactic acid (PLA) iyinoveli esekelwe ku-bio-based and renewable biodegradable material, eyenziwe ngezinto zesitashi ezihlongozwe izinsiza zezitshalo ezivuselelekayo (njengommbila nomdumbula). Izinto zokusetshenziswa zesitashi zakhishwa ukuze kutholwe ushukela, kwase kuthi ukuhlanzeka okuphezulu kwe-lactic acid kwenziwa ngokuvutshelwa kweglucose nezinhlobo ezithile, kwase kuthi i-Polylactic acid enesisindo esithile samangqamuzana yahlanganiswa ngokuhlangana kwamakhemikhali. Ine-biodegradability enhle. Ngemuva kokusetshenziswa, kungacekelwa phansi ngokuphelele ama-microorganisms emvelweni ngaphansi kwezimo ezithile, futhi ekugcineni kukhiqize i-carbon dioxide namanzi. Ayingcolisi imvelo, okuzuzisa kakhulu ekuvikelweni kwendawo ezungezile futhi yaziwa njengempahla evikela imvelo. I-China PP Intengo Yendwangu Engalukiwe
I-PLA,futhi efana nolunye uhloboI-PET spunbond,inokudonseka okuhle kakhulu, ukushelela, ukumunca umswakama kanye nokungena komoya, i-bacteriostasis yemvelo kanye nesikhumba eqinisekisa i-asidi ebuthakathaka, ukumelana nokushisa okuhle kanye nokumelana ne-UV.
I-PLA yonke ibhalwe njenge-:polylactic acid
I-Polylactic acid, eyaziwa nangokuthi i-polylactide, ingeyomndeni we-polyester. I-Polylactic acid (i-PLA) iyi-polymer etholakala ngokwenza i-polymerization ye-lactic acid njengento eyinhloko eluhlaza. Umthombo wempahla eluhlaza wanele futhi ungagaywa kabusha. Isebenzisa kakhulu ummbila kanye nomdumbula njengezinto ezingavuthiwe. Inqubo yokukhiqiza ye-PLA ayingcolisi, futhi umkhiqizo ungashintshwa ukuze ubone umjikelezo emvelweni, ngakho-ke iyinto efanelekile ye-polymer eluhlaza.
I-Polylactic acid inokuqina okuhle kokushisa, izinga lokushisa lokucubungula 170 ~ 230 ℃, ukumelana okuhle kwe-solvent, lingacutshungulwa ngezindlela ezihlukahlukene, njenge-extrusion, ukuphotha, ukunwebeka kwe-biaxial, ukubunjwa kokushaywa komjovo. Imikhiqizo eyenziwe nge-polylactic acid ayigcini nje ngokubola, kodwa futhi ine-biocompatibility enhle, i-gloss, obala, ukuzwa nokumelana nokushisa. Futhi banokuphikiswa okuthile kwamagciwane, i-flame retardant kanye nokumelana kwe-UV, ngakho-ke asetshenziswa kabanzi njengezinto zokupakisha, imicu kanye nama-nonwovens, njll. Okwamanje, isetshenziswa kakhulu ezingutsheni (zangaphansi, izingubo zangaphandle), imboni (ukwakha, ezolimo, amahlathi. , ukwenza amaphepha) kanye nezinkambu zezokwelapha nempilo.
