PLA yog ib qho ntawm cov khoom siv yas degradable. Polylactic acid yog ib qho polymerized los ntawm lactic acid ua cov khoom tseem ceeb. Tam sim no, nws yog cov laus tshaj plaws, qhov loj tshaj plaws thiab siv dav siv biodegradable yas hauv ntiaj teb.
Muaj ob txoj hauv kev rau PLA ntau lawm, uas yog lub nplhaib lactide-qhib polymerization thiab ncaj qha polycondensation, uas yog siv los ntawm lactide nplhaib-qhib polymerization. Nyob rau hauv lactide nplhaib-qhib polymerization, lub synthesis thiab purification ntawm intermediate lactide yog cov tub ntxhais technology thiab nyuaj rau cov txheej txheem. Cov tshuaj tiv thaiv tej yam kev mob hnyav, cov txheej txheem yog complex, cov kev xav tau siab, thiab cov nqi ntau lawm yog siab.
