Ua ntej txheeb xyuas qhov zoo thiab qhov tsis zoo ntawm biodegradable plastics, vim li cas peb thiaj li tsim cov yas biodegradable?
Txij li thaum yug los ntawm cov khoom yas, thaum coj kev yooj yim rau tib neeg lub neej, lawv tau ua rau muaj kuab paug ntau dua rau ib puag ncig vim lawv tsis muaj degradability, yog li nws yog qhov tsim nyog los tswj lawv thiab txhim kho cov khoom siv. Nws yog nyob rau hauv keeb kwm yav dhau no uas biodegradable plastics tshwm sim. Nws yog tsim los ntawm raw cov ntaub ntawv muab rho tawm los ntawm cov nroj tsuag, muaj peev xwm ua tau tej yam ntuj tso decomposition thiab tus phooj ywg rau ib puag ncig.
Ntawm no peb xav qhia txog qhov zoo thiab qhov tsis zoo ntawm cov khoom siv no, kom pom tias vim li cas cov khoom siv no tau dhau los ua qhov sib txawv loj.
Qhov zoo ntawm biodegradable plastics yog:
1. Txo cov pa roj carbon emissions.
Piv nrog cov khoom siv yas,biodegradable plastics xa ntawvyog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev txo cov txheej txheem tsim cov pa roj carbon emissions thiab tsim cov pa roj carbon tsawg tsawg hauv cov txheej txheem composting.
2. Tsawg zog siv.
Txog tam sim no, kev nqis peev ntawm cov khoom siv yas biodegradable yog me ntsis, tab sis nyob rau lub sijhawm ntev, cov yas zoo tib yam yuav tsum tau rov ua dua tshiab los ua cov polymer ntawm fossil fuels, thiab biodegradable plastics xav tau lub zog tsawg dua, uas tuaj yeem paub txog kev ua qias tuaj thiab ib puag ncig.
3. Cov yas zoo duantim cov kev daws teeb meem.
Siv cov khoom yas biodegradable tshwj xeeb tshaj yog rov ntim, twb tuaj yeem hloov cov khoom siv yas ntau tshaj plaws, thiab nws twb tau daws cov yam ntxwv thiab kev ua haujlwm tsis txaus. Nws tau dhau los ua thawj qhov kev xaiv rau cov npe loj.
Qhov tsis zoo ntawm biodegradable plastics yog:
1. Hnub tim.
Biodegradable yas xa ntawvmuaj lub neej txee, tom qab ntawd cov khoom ntawm lub cev yuav poob qis. Piv txwv li, lub sij hawm tas sij hawm ntawm biodegradable hnab uas tsim los ntawm Xim-P yog 1 xyoo, tom qab ntawd nws muaj peev xwm yellowish, ntug seal firmness poob, thiab yooj yim los tsim kua muag.
2. Kev cia khoom.
Biodegradable yas khoom yuav tsum tau muab cia rau hauv tej yam kev mob. Nws raug nquahu kom khaws cia rau hauv qhov chaw qhuav, kaw, thiab txias; Tsis txhob muaj av noo, kub kub thiab ncaj qha ultraviolet rays, txwv tsis pub lub hnab yuav deteriorate thiab ceev degradation.
Yog li ntawd, txawm tias qhov tsis zoo ntawm biodegradable plastics, qhov zoo ntawm biodegradable plastics tag nrho tshaj qhov tsis zoo thiab ua rau lawv xaiv zoo dua piv rau cov khoom yas zoo tib yam vim muaj kev paub txog kev nyab xeeb ntawm ib puag ncig.
