Nplua nuj khoom siv khoom siv raw
Cov ntaub ntawv raw siv los tsim cov peev txheej polylacic (PLA) los ntawm cov khoom siv tau yooj yim xws li cov pob kws txuas ntxiv zoo li cov roj av lossis ntoo, yog li pab tiv thaiv cov khoom siv roj.
Lub cev zoo dua qub
PLA yog haum rau ntau txoj kev xws li tshuab moulding thiab thermopastics, tsis muaj cov khoom noj khoom haus, cov ntaub qhwv khoom noj, thiab muaj kev ua lag luam cov khoom lag luam thiab pej xeem muaj zog heev.
Biocompatibility
Pla kuj muaj biocompatibilibility zoo, thiab nws cov khoom lag luam tsis zoo, l-lactic acid, tuaj yeem koom nrog hauv tib neeg cov metabolism. Nws tau pom zoo los ntawm Asmeskas Cov Khoom Noj thiab Tshuaj Siv Tshuaj (FDA) thiab tuaj yeem siv ua kev phais cov tshuaj tiv thaiv kev kho mob, tsom iav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav, thiab kev cog hniav.
Ua pa zoo
Cov zaj duab xis muaj cov pa ua pa zoo, oxygen permeability, thiab carbon dioxide permeability, thiab kuj muaj cov yam ntxwv ntawm kev rho tawm cais. Cov kab mob thiab pwm tau yooj yim rau txuas rau saum npoo ntawm biodegradable plastics, yog li muaj kev nyab xeeb thiab kev txhawj xeeb txog kev nyab xeeb. Txawm li cas los xij, PLA yog tsuas yog cov yas biodegradable nrog cov tshuaj tua kab mob zoo heev thiab tiv thaiv pwm.
Biodegradity
PLA yog ib qho kev tshawb fawb tshaj plaws hauv Suav teb thiab txawv teb chaws, thiab nws peb qhov chaw kub muaj khoom ntim, cov khoom siv hluav taws xob, thiab khoom siv kho mob.
PLA, uas yog ua los ntawm ntuj lactic acid, muaj zoo biodegradability thiab biocompatibility, thiab nws lub neej kev cuam tshuam ntau dua li cov khoom siv roj av. Nws suav hais tias yog cov lus cog tseg tau ntim khoom ntsuab rau kev txhim kho.
Raws li hom tshiab ntawm cov ntshiab biological khoom, pla muaj kev lag luam lag luam zoo. Nws cov khoom zoo lub cev thiab ib puag ncig cov phooj ywg yuav undoubtedly ua rau cov pla siv ntau dua nyob rau yav tom ntej.
