Vim li cas PLA Biodegradable thiaj li nrov thiab nrov dua?

PLA yog dab tsi?

Polylactic acid (PLA) yog cov khoom siv biodegradable tshiab ua los ntawm cov hmoov txhuv nplej siab raw cov ntaub ntawv uas tau thov los ntawm cov khoom siv txuas ntxiv mus ntxiv xws li pob kws. Cov hmoov txhuv nplej siab raw khoom yog saccharified kom tau cov piam thaj, thiab tom qab ntawd fermented los ntawm cov piam thaj thiab qee hom los tsim cov purity lactic acid, thiab tom qab ntawd ua ke polylactic acid nrog qee qhov hnyav molecular los ntawm cov tshuaj synthesis. Nws muaj biodegradability zoo thiab tuaj yeem degraded tag nrho los ntawm cov kab mob hauv cov kab mob tom qab siv, nws thiaj li tsim cov pa roj carbon dioxide thiab dej tsis muaj kuab paug rau ib puag ncig, uas muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab tau lees paub tias yog cov khoom siv zoo ib puag ncig.
Qhov zoo ntawm PLA

1. Muaj peev txheej ntawm cov khoom siv raw

• Cov khoom siv raw rau kev tsim cov polylactic acid yog cov khoom siv txuas ntxiv dua tshiab xws li pob kws, tsis tas siv cov khoom muaj txiaj ntsig zoo xws li roj av thiab ntoo, yog li nws yuav ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv roj av ntau zuj zus.

2. Lub cev zoo tshaj plaws

• Polylactic acid yog tsim rau ntau yam kev ua xws li tshuab moulding thiab thermoplastic, thiab yog ib qho yooj yim rau txheej txheem thiab dav siv. Nws tuaj yeem siv los ua ntau yam khoom siv yas los ntawm kev lag luam mus rau kev siv pej xeem, ntim khoom noj, cov thawv ntim khoom noj ceev ceev, cov ntaub ntawv tsis-woven, cov khoom lag luam thiab cov ntaub ntawv pej xeem. Tom qab ntawd nws tuaj yeem ua tiav rau hauv cov ntaub ua liaj ua teb, cov ntaub ntawv kho mob, rags, cov khoom siv tu cev, sab nraum zoov los tiv thaiv ultraviolet fabrics, tsev pheeb suab ntaub, ntaub pua plag, thiab lwm yam.

3. Biocompatibility

• Polylactic acid 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 sutures thiab txhaj tshuaj capsules.

4. Zoo huab cua permeability

• Polylactic acid (PLA) zaj duab xis muaj huab cua zoo permeability, oxygen permeability thiab carbon dioxide permeability, thiab nws kuj muaj cov cuab yeej ntawm kev cais tawm tsw. Cov kab mob thiab cov pwm yog ib qho yooj yim mus txuas rau saum npoo ntawm biodegradable plastics, yog li muaj kev tsis ntseeg txog kev nyab xeeb thiab kev nyiam huv. Txawm li cas los xij, polylactic acid yog cov yas biodegradable nkaus xwb nrog cov tshuaj tua kab mob zoo heev thiab tiv thaiv kab mob mildew.

5. Biodegradability

• Polylactic acid (PLA) tuaj yeem rhuav tshem tag nrho los ntawm cov kab mob tom qab siv, thiab thaum kawg tsim cov pa roj carbon dioxide thiab dej tsis muaj kuab paug ib puag ncig. Qhov no muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig thiab raug lees paub tias yog cov khoom siv zoo ib puag ncig.

Txoj kev loj hlob ntawm PLA yog dab tsi?

PLA yog ib qho ntawm cov ntaub ntawv tshawb fawb biodegradable hauv tsev thiab txawv teb chaws. Cov ntim khoom noj, cov tais diav pov tseg thiab cov ntaub ntawv kho mob yog nws peb qhov chaw thov nrov. Raws li hom tshiab ntawm cov khoom siv ntshiab bio-raws li, nws muaj kev ua lag luam zoo rau kev thov. Nws cov khoom zoo ntawm lub cev thiab kev tiv thaiv ib puag ncig ntawm cov khoom nws tus kheej yuav ua rau PLA siv ntau dua yav tom ntej.
