Polylactic acid (PLA) muaj lub zog tensile zoo tshaj plaws thiab ductility. PLA kuj tseem tuaj yeem tsim los ntawm ntau txoj kev ua tiav, xws li melting extrusion molding, txhaj tshuaj molding, zaj duab xis tshuab molding, foaming molding thiab nqus tsev molding. Nws muaj cov xwm txheej zoo sib xws nrog cov polymers siv dav. Tsis tas li ntawd, nws kuj muaj kev ua tau zoo tib yam li cov yeeb yaj kiab ib txwm muaj. Ua li no, polylactic acid tuaj yeem ua rau ntau yam khoom siv raws li qhov xav tau ntawm ntau yam lag luam.
Zaj duab xis Lactic acid (PLA) muaj huab cua zoo permeability, oxygen permeability thiab carbon dioxide permeability. Nws kuj muaj cov yam ntxwv ntawm kev cais cov ntxhiab tsw. Cov kab mob thiab pwm yooj yim lo rau ntawm qhov chaw ntawm cov yas biodegradable, yog li muaj kev tsis ntseeg txog kev nyab xeeb thiab kev tu cev. Txawm li cas los xij, polylactic acid yog tib cov yas biodegradable nrog kev tiv thaiv kab mob zoo heev thiab mildew.
Thaum hlawv polylactic acid (PLA), nws cov calorific nqi combustion yog tib yam li cov ntawv hlawv, uas yog ib nrab ntawm cov incinerating ib txwm plastics (xws li polyethylene), thiab incineration ntawm PLA yuav tsis tso tawm cov pa phem xws li nitrides thiab sulfides. Tib neeg lub cev kuj muaj lactic acid nyob rau hauv daim ntawv ntawm monomer, uas qhia txog kev nyab xeeb ntawm cov khoom decomposition no.
