PLA yog dab tsi

Apr 26, 2023 Tso lus

Polylactic acid, feem ntau hu ua PLA, yog ib qho thermoplastic monomer ua los ntawm cov organic, regenerative kev pab xws li qab zib los yog pob kws starch. Tsis zoo li feem ntau ntawm cov yas, uas yog tsim los ntawm fossil fuels los ntawm distilling thiab polymerizing roj av, PLA yog tsim los ntawm biomass peev txheej.

 

Txawm hais tias muaj qhov sib txawv ntawm cov khoom siv raw, PLA yuav raug tsim los siv tib lub tshuab xws li petrochemical plastics, uas ua rau cov txheej txheem tsim khoom rau PLA tau txais txiaj ntsig zoo. Tom qab cov hmoov txhuv nplej siab thermoplastic, PLA yog bioplastic uas tau ua thib ob feem ntau. Nws cov khoom zoo ib yam li cov polypropylene (PP), polyethylene (PE), thiab polystyrene (PS), thiab nws kuj yog biodegradable.
