I-Polylactic acid (H- [OCHCH3CO]n-OH) inozinzo oluhle lwe-thermal, ubushushu bokusebenza yi-170～230℃, kwaye inokumelana nokunyibilikisa okulungileyo.Inokucutshungulwa ngeendlela ezahlukeneyo, ezifana ne-extrusion, i-spinning, i-biaxial stretching, i-Injection blow molding.Ukongeza kwi-biodegradable, iimveliso ezenziwe nge-polylactic acid zine-biocompatibility efanelekileyo, i-gloss, i-transparency, ukuvakalelwa kwesandla kunye nokumelana nobushushu.I-polylactic acid (PLA) ephuhliswe nguGuanghua Weiye nayo ineempawu ezithile ze-antibacterial kunye ne-flame retardant.Kwaye ukuxhathisa kwe-UV, ngoko inoluhlu olubanzi lokusetyenziswa.Ingasetyenziswa njengezinto zokupakisha, iifayibha kunye nee-nonwovens, njl njl. Isetyenziswa kakhulu kwimpahla (impahla yangaphantsi, impahla yangaphandle), ishishini (ukwakha, ezolimo, amahlathi, ukwenza iphepha), kunye nezonyango kunye nezempilo.
Iinzuzo eziphambili ze-polylactic acid zezi zilandelayo:
I-Polylactic acid (PLA) luhlobo olutsha lwezinto ezinokubola, ezenziwe kwi-starch ekrwada ecetywayo yimithombo yezityalo ezivuselelekayo (ezifana nombona).Isitashi izinto ekrwada zifakwa saccharified ukufumana iswekile, nto leyo ke ivundiswe iswekile kunye iintlobo ezithile ukuvelisa i-asidi lactic high-ubunyulu, kwaye ke imolekyuli ethile ubunzima polylactic acid idityaniswe nge synthesis imichiza.Inokonakala kwezinto eziphilayo.Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo yi-microorganisms kwindalo, kwaye ekugqibeleni i-carbon dioxide kunye namanzi ziveliswa ngaphandle kokungcolisa indalo.Oku kuluncedo kakhulu ekukhuselweni kwendalo kwaye kubonwa njengento ehambelana nokusingqongileyo.Iiplastiki eziqhelekileyo zisaphathwa ngokutshiswa kunye nokutshiswa, okubangela ukuba kukhutshwe igesi enkulu ye-greenhouse emoyeni, ngelixa iiplastiki ze-polylactic acid zingcwatyelwa emhlabeni ukuze zithobeke, kwaye i-carbon dioxide eveliswayo ingena ngokuthe ngqo kumhlaba we-organic matter okanye ifunxwe. ngezityalo, kwaye ayiyi kukhutshelwa emoyeni.Ayiyi kubangela impembelelo ye-greenhouse.
