I-Polylactic acid (H--[OCHCH3CO]n-OH) inokusimama okuhle kwe-thermal, izinga lokushisa lokucubungula ngu-170～230℃, futhi inokumelana okuhle kwe-solvent.Ingacutshungulwa ngezindlela ezihlukahlukene, njenge-extrusion, ukuphotha, ukunwebeka kwe-biaxial, ukubunjwa kokushaywa komjovo.Ngaphezu kokuthi i-biodegradable, imikhiqizo eyenziwe nge-polylactic acid inokuvumelana okuhle kwe-biocompatibility, isicwebezelisi, obala, ukuzwa kwezandla kanye nokumelana nokushisa.I-polylactic acid (PLA) eyakhiwe ngu-Guanghua Weiye futhi inezindawo ezithile zokulwa namagciwane kanye ne-flame retardant.Futhi ukumelana kwe-UV, ngakho-ke inokusetshenziswa okubanzi.Ingasetshenziswa njengezinto zokupakisha, imicu kanye nama-nonwovens, njll. Isetshenziswa kakhulu kwezokugqoka (izingubo zangaphansi, izingubo zangaphandle), imboni (ezokwakha, ezolimo, ezamahlathi, ukwenza amaphepha), kanye nezinkambu zezokwelapha nempilo.
Izinzuzo eziyinhloko ze-polylactic acid zimi kanje:
I-Polylactic acid (PLA) iwuhlobo olusha lwezinto ezibolayo, ezenziwe ngesitashi sezinto ezingavuthiwe ezihlongozwe izinsiza zezitshalo ezivuselelekayo (njengommbila).Izinto ezisetshenziswayo zesitashi ziyahlanjululwa ukuze kutholwe i-glucose, ebisivutshelwa nge-glucose nezinye izinhlobo ukuze kukhiqizwe i-lactic acid ehlanzekile, bese kuthi i-polylactic acid yesisindo samangqamuzana ihlanganiswe ngokuhlangana kwamakhemikhali.Ine-biodegradability enhle.Ngemuva kokusetshenziswa, kungonakalisa ngokuphelele ama-microorganisms emvelweni, futhi ekugcineni i-carbon dioxide namanzi akhiqizwa ngaphandle kokungcolisa imvelo.Lokhu kuzuzisa kakhulu ekuvikelweni kwemvelo futhi kuqashelwa njengento ehambisana nemvelo.Amapulasitiki avamile asaphathwa ngokushiswa nokushiswa kwesidumbu, okwenza inani elikhulu lamagesi abamba ukushisa akhishelwe emoyeni, kuyilapho amapulasitiki e-polylactic acid egqitshwa enhlabathini ukuze ayonakalise, futhi isikhutha esikhiqizwayo singena ngqo enhlabathini yezinto eziphilayo noma simuncwe. ngezitshalo, futhi ngeke zikhishelwe emoyeni.Ngeke kubangele umphumela we-greenhouse.
