Impahla ye-BBCA polylactic acid iimveliso ezintsha

I-Polylactic acid (i-PLA) luhlobo lwemathiriyeli entsha eveliswa yipolymerization eyongezelelweyo ye-lactic acid kwi-starch okanye iswekile fermentation. Ayisebenzisi i-petroleum njengento eluhlaza, kwaye ineempawu zokukhuselwa kwendalo, i-non-toxic, i-antibacterial, i-flame retardant, i-biocompatibility efanelekileyo kunye ne-biodegradability. Yeyona nto intsha ithembisayo ukushukuma indawo yemveli yeeplastiki ezisekwe kwipetroleum kunye nemicu yemichiza kwixesha elizayo.

I-Polylactic acid kunye neemveliso zayo zineempawu ezizinzileyo zomzimba phantsi kobushushu obuqhelekileyo kunye neemeko zomswakama. Yi-biomaterial eyonakele ngokupheleleyo, enokuthi iphinde isetyenziswe. Emva kokulahlwa, inokuthotywa ibe yi-carbon dioxide kunye namanzi. Emva kwephotosynthesis zizityalo, inokufunxwa zizityalo kwakhona kwaye ingene kwisangqa sendalo ngokungapheliyo. "Yimathiriyeli yokurisayikilisha kokusingqongileyo yenkulungwane yama-21".

Iimpawu eziphambili zezi zilandelayo

(1) imithombo ehlaziyekayo: ubukhulu becala ivela kumbona, iitapile kunye nezinye izityalo zesitatshi, kunye neendiza zezityalo, njl.njl;

(2) ukuwohloka ngokupheleleyo kwezinto eziphilayo: inokufunxwa ize yenziwe ngumzimba womntu; iimveliso zihlanjululwe ngokupheleleyo kwi-CO2 kunye ne-H2O kumhlaba okanye emanzini olwandle emva kokulahlwa kwi-landfill kunyaka omnye, ukuqonda umjikelezo wekhabhoni phezu komhlaba kunye nokutshintsha ngokufanelekileyo ukungcoliseka kokusingqongileyo okubangelwa izinto ezisekelwe kwi-petroleum;

(3) ubudlelwane bomzimba womntu kunye nokhuseleko: i-lactic acid ekrwada iqulethwe emzimbeni womntu, i-PLA inokuthi ifakwe i-metabolized kwaye ifunnwe ngumzimba womntu, i-PLA yi-FDA eqinisekisiweyo yezinto zokufakelwa komntu, eziye zasetyenziswa ngokubanzi kwintsimi yezonyango amashumi eminyaka;

(6) ukubuyiswa komlilo wendalo: ukunqanda amadangatye akhuselekile, umsi ophantsi, akukho msi mnyama kwaye akukho gesi inetyhefu;

(7) iglosi egqwesileyo, ukucaca, ukubamba, ukuxhathisa kwe-UV, ukuhanjiswa kokufuma, akukho kuphinda kufumaneke ukufuma, njl.

I-Polylactic acid inokwenziwa ibe yifayibha ye-polylactic acid, kwaye ukusebenza kwayo kuthelekiswa nekotoni. Ukongezelela, i-polylactic acid inokusebenza okufanayo kwizinto eziqhelekileyo zeekhemikhali ezifana ne-polypropylene (PP), i-polyethylene (PE), i-polyester fibers (i-PET, i-PTT, i-PBT). Inokucutshungulwa ngokubumba inaliti, i-extrusion, ijikelezisa kunye nezinye iinkqubo zokwenza imicu, iifilim, amashiti kunye neepleyiti, ngokuthe ngcembe ithathela indawo imicu yePetrochemical kunye neeplastiki zepetroleum, Isetyenziswa kakhulu kwimpahla, ukupakisha, ezolimo, ikhaya, iinxalenye zemoto, ukuprintwa kwe-3D. , biomedicine kunye nezinye iinkalo ezininzi.
