Puas yog PLA tiag tiag eco-phooj ywg?
Polylactic acid, los yog PLA, yog ib hom biodegradable yas uas nquag siv los ua cov khoom noj khoom haus pov tseg, khoom siv kho mob, thiab ntim khoom noj. Raws li kev tshawb fawb tsis ntev los no, PLA muaj kev nyab xeeb rau tib neeg thiab tsis muaj qhov tsis zoo rau lawv ncaj qha.
PLA muaj qee qhov txiaj ntsig ntawm kev txuag ib puag ncig vim tias nws yog tsim los ntawm ib txwm muaj lactic acid molecules uas yog polymerized thiab tuaj yeem tawg ua carbon dioxide thiab dej hauv ntiaj teb ntuj. Nyob rau hauv sib piv rau cov pa polymers, PLA tsis tsim teeb meem los yog mob qog noj ntshav los yog muaj kev phiv rau tib neeg noj qab haus huv. Artificial pob txha thiab sutures tsuas yog ob qho piv txwv ntawm cov khoom kho mob uas twb tau siv ntau ntawm PLA.
Nws yuav tsum tau hais, txawm li cas los xij, qee yam ntawm cov tshuaj siv los ua PLA tuaj yeem cuam tshuam rau ib puag ncig thiab tib neeg kev noj qab haus huv. Piv txwv li, benzoic acid thiab benzoic anhydride yog siv nyob rau hauv cov synthesis ntawm PLA thiab nyob rau hauv ntau npaum li cas yuav ua rau muaj kev phom sij rau tib neeg. Tsis tas li ntawd, ntau lub zog xav tau los tsim PLA, thiab kev siv lub zog ntau dhau yuav ua rau muaj ntau cov pa phem thiab cov pa phem hauv tsev cog khoom uas yuav ua rau ib puag ncig.
Raws li qhov tshwm sim, PLA yog qhov tsim nyog rau kev siv hauv kev npaj zaub mov thiab kev noj zaub mov ntev npaum li kev nyab xeeb thiab kev txhawj xeeb ntawm ib puag ncig raug coj los xav.
