XOV XWM - Cov ntaub ntawv dab tsi yog cov txheej txheem sib xyaw ua los ntawm?

Cov ntaub ntawv twg yog cov txheej txheem sib xyaw ua los ntawm?

Nyob rau hauv lub wake ntawm ib puag ncig ib puag ncig, compstosable plastics tau tshwm sim raws li lub focal taw tes ntawm kev xaiv kom muaj kev xaiv. Tab sis dab tsi raws nraim yog compstable plastics ua los ntawm? Cia delve mus rau hauv cov lus nug intriguing.

1. Cov qauv ntawm Bio-based plastics

Bio-based plastics yog muab los ntawm biomass txuas ntxiv, feem ntau suav nrog cov roj av, pob kws ua pob kws, ntoo. Piv rau cov kev ua roj av ib txwm muaj, raws li cov plastics, bio raws plastics emit tsawg dua cov roj av roj av thaum tsim khoom thiab muaj peev txheej ib puag ncig zoo.

2. Cov yam ntxwv ntawm compstable plastics

Compstable plastics, ib subset ntawm bio-based plastics, yog qhov txawv los ntawm lawv lub peev xwm los decompose rau hauv cov organic teeb meem hauv cov chaw nplooj lwg. Qhov no txhais tau tias tsis zoo li cov khoom lag luam yas, compstosable plastics ib txwm muaj kev qias neeg tom qab pov tseg ib puag ncig kev qias neeg.

3. Cov ntaub ntawv siv hauv Compostable yas ntau lawm

Cov ntaub ntawv siv nyob rau hauv Compostable yas ntau lawm siv cov xyoob ntoo biodegradable xws li pob kws hmoov nplej, kab tsib, thiab ntoo ntoo. Cov khoom siv raw tau dhau los ua cov kauj ruam kev ua, suav nrog polymerization los tsim cov pellets yas, ua kom molding cov khoom lag luam, lossis lwm cov txheej txheem los tsim cov khoom lag luam yas.

4. Mechanism ntawm biodegradation

Lub biodegradation ntawm compstable plastics tshwm sim los ntawm kev nqis tes ua ntawm cov microrganisms. Nyob rau hauv cov nplooj lwg ib puag ncig, cov kab mob me me zom cov saw hlau polymer ntawm cov yas, hloov lawv mus rau hauv cov molecules me. Cov molecules organic no tuaj yeem decomposed los ntawm cov microorganisms hauv av, thaum kawg hloov mus rau hauv cov roj carbon dioxide thiab dej, sib xyaw ua ke rau hauv lub voj voog ntuj.

5. Kev thov thiab yav tom ntej saib ntawm compstable plastics

Compostable plastics tam sim no dav siv nyob rau hauvCov Khoom Uas Siv Khoom, ntim khoom, thiab lwm yam. Nrog kev txhim kho txuas ntxiv ntawm ib puag ncig ib puag ncig, kev ua lag luam xav tau rau cov pa hluav taws xob muaj kev nce ntxiv. Nyob rau yav tom ntej, raws li thev naus laus zis kev nce qib, kev ua tau zoo thiab tus nqi ntawm cov compstable plastics yuav tau ua kom zoo dua, ua rau kev txhawb zog ntxiv rau kev txhim kho kom ruaj khov.

Hauv kev xaus, compostable plastics, raws li cov khoom siv hauv eco-phooj ywg, feem ntau tsim ntawm biodegradable polymers. Los ntawm kev nqis tes ua ntawm cov microorganisms, lawv yauv yov beegegradation nyob rau hauv ib puag ncig nplooj lwg, muab kev daws cov lus cog tseg los txo cov kuab paug yas. Nrog lawv cov ntawv thov dav dav thiab kev cog lus cia thiab cuam tshuam cov kev cia siab yog cov lus ntuas kom tsim cov tshuaj ntxuav kom huv rau tib neeg.
