PLA yog cov lus Askiv luv ntawm polylactic acid. Lub npe lus Askiv yog Polylactic Acid lossis Polylactide. Nws yog cov khoom condensation ntawm -hydroxypropionic acid thiab belongs rau ib hom thermoplastic aliphatic polyester.
Lub monomer raw khoom ntawm PLA yog lactic acid, uas yog feem ntau tau los ntawm crushing plhaub cov qoob loo xws li pob kws, extracting starch los ntawm nws, thiab ces hloov cov hmoov txhuv nplej siab rau hauv unrefined qabzib. Cov piam thaj yog ces fermented nyob rau hauv ib tug zoo xws li kev tsim ntawm npias los yog cawv, thiab thaum kawg lub lactic acid monomer yog tau los ntawm ib tug purification txheej txheem.
Polylactic acid (PLA) yog ib hom tshiab ntawm biodegradable khoom, haum rau ntau yam kev ua xws li extrusion, txhaj molding, zaj duab xis, spinning, thiab lwm yam. Nws yog ib qho yooj yim rau txheej txheem, yog li nws yuav siv tau nyob rau hauv cov zaub mov ntim, ceev noj su. thawv, non-woven fabrics, Industrial thiab civilian fabrics, ua liaj ua teb fabrics, 3D printing thiab lwm yam teb.
Raws li cov ntaub ntawv tshawb fawb, kev siv cov ntaub ntawv PLA hauv cov ntim khoom noj thiab cov tais diav muaj ntau dua 66 feem pua, ua raws li kev kho mob thiab kev saib xyuas tus kheej, suav txog 28 feem pua.
