Ntau cov khoom siv raw
Cov khoom siv raw siv los tsim cov tshuaj polylactic acid (PLA) yog los ntawm cov khoom siv txuas ntxiv dua tshiab xws li pob kws, tsis tas yuav muaj cov peev txheej muaj txiaj ntsig zoo li roj av lossis ntoo, yog li pab tiv thaiv cov khoom siv roj dwindling.
Superior lub cev muaj zog
PLA yog tsim rau ntau yam txheej txheem xws li tshuab moulding thiab thermoplastics, ua rau nws yooj yim rau txheej txheem thiab siv tau rau ntau yam khoom yas, ntim khoom noj, thawv khoom noj ceev, tsis-woven fabrics, industrial thiab civilian fabrics, thiab muaj ib tug heev. kev cia siab ua lag luam outlook.
Biocompatibility
PLA kuj muaj biocompatibility zoo heev, thiab nws cov khoom degradation, L-lactic acid, tuaj yeem koom nrog hauv tib neeg cov metabolism.Nws tau raug pom zoo los ntawm US Food and Drug Administration (FDA) thiab tuaj yeem siv los ua kev kho mob phais suture, txhaj tshuaj ntsiav, microspheres, thiab cog qoob loo.
Zoo breathability
PLA zaj duab xis muaj kev ua pa zoo, oxygen permeability, thiab carbon dioxide permeability, thiab tseem muaj cov yam ntxwv ntawm kev cais tawm tsw.Cov kab mob thiab pwm yog ib qho yooj yim mus txuas rau saum npoo ntawm biodegradable plastics, yog li muaj kev txhawj xeeb txog kev nyab xeeb thiab kev nyiam huv.Txawm li cas los xij, PLA tsuas yog biodegradable yas nrog cov tshuaj tua kab mob zoo heev thiab tiv thaiv pwm.
Biodegradability
PLA yog ib qho ntawm cov ntaub ntawv tshawb fawb biodegradable tshaj plaws nyob rau hauv Suav teb thiab txawv teb chaws, thiab nws peb qhov chaw siv kub kub yog cov khoom ntim khoom noj, cov tais diav pov tseg, thiab cov ntaub ntawv kho mob.
PLA, uas yog tsim los ntawm ntuj lactic acid, muaj biodegradability zoo thiab biocompatibility, thiab nws lub neej voj voog muaj kev cuam tshuam ib puag ncig qis dua li cov khoom siv roj av.Nws suav hais tias yog cov khoom lag luam zoo tshaj plaws rau kev tsim kho.
Raws li hom tshiab ntawm cov khoom siv roj ntsha ntshiab, PLA muaj kev cia siab rau kev lag luam zoo.Nws lub cev zoo thiab kev phooj ywg ib puag ncig yuav ua rau PLA tau siv ntau dua yav tom ntej.
