PLA yog dab tsi? - Tshawb nrhiav Lub Hnub Qub Rising ntawm Biodegradable Plastics

2025-03-19

PLA, luv rau Polylactic Acid, yog ib hom yas uas lwj tau los ntawm cov nroj tsuag uas rov ua dua tshiab xws li pob kws thiab cassava. Nws raug hu ua lwm txoj hauv kev zoo rau ib puag ncig piv rau cov yas ib txwm muaj, muab kev cia siab tshiab rau kev daws teeb meem ntawm kev ua qias tuaj dawb.

Cov txheej txheem tsim khoom ntawm PLA feem ntau muaj ob kauj ruam: thawj zaug, hloov cov hmoov txhuv nplej siab hauv cov nroj tsuag mus rau hauv lactic acid los ntawm cov txheej txheem fermentation; tom qab ntawd, polymerizing cov lactic acid mus rau hauv cov khoom siv high-molecular-weight los ntawm kev tsim tshuaj lom neeg. Cov khoom siv no tsis yog tsuas yog los ntawm cov chaw rov ua dua tshiab xwb tab sis kuj tuaj yeem lwj tag nrho mus rau hauv dej thiab carbon dioxide nyob rau hauv cov xwm txheej tshwj xeeb, tsis ua rau muaj kev puas tsuaj rau ib puag ncig.

Tam sim no, PLA siv dav hauv kev ntim khoom, kev pabcuam zaub mov, 3D luam ntawv, thiab lwm yam. Piv txwv li, cov khoom siv pov tseg, cov thawv ntim khoom noj, thiab cov ntawv thov kho mob xws li cov xov thiab cov stents txhua tus siv cov ntaub ntawv PLA. Nws qhov kev sib raug zoo zoo heev thiab kev puas tsuaj ntawm cov khoom ua rau nws sawv cev rau cov ntaub ntawv ntsuab.

Txawm li cas los xij, kev txhawb nqa PLA tseem ntsib qee qhov teeb meem. Nws cov nqi tsim khoom kim heev, thiab nws qhov kev puas tsuaj yuav tsum muaj cov xwm txheej tshwj xeeb ntawm kev ua composting hauv kev lag luam, ua rau nws qhov kev puas tsuaj qeeb dua hauv cov chaw ib puag ncig ntuj. Tsis tas li ntawd, kev paub txog kev ua lag luam thiab kev txwv tsis pub siv cov khoom siv loj.

Txawm li cas los xij, ua ib yam khoom siv uas zoo rau ib puag ncig, PLA muaj lub neej yav tom ntej zoo. Nrog kev nce qib hauv thev naus laus zis thiab kev txhawb nqa txoj cai, PLA yuav tsum dhau los ua lwm txoj hauv kev rau cov yas ib txwm muaj, pab txhawb rau kev tsim kom muaj lub neej yav tom ntej ruaj khov.
