Thaum soj ntsuam cov macro thiab micro kev lag luam loj hlob tsis tau ntawm cov rooj tog yas ua lag luam.Txoj kev tshawb no muab kev nkag siab zoo rau cov kev hloov pauv uas tuaj yeem cuam tshuam cov tswv yim ntawm cov neeg koom nrog kev lag luam hauv ob peb xyoos tom ntej.Cov kev tshawb fawb qhia tau hais tias kev txhim kho txuas ntxiv ntawm engineering plastics thiab kev mloog zoo rau cov khoom siv rov ua dua tshiab yuav txuas ntxiv los pab txhim kho lub neej yav tom ntej ntawm kev lag luam rooj tog yas.
Txoj kev tshawb no pom tias South Asia cov thawj coj ntawm cov rooj tog yas yog tam sim no ua haujlwm hauv cov khw muag khoom rooj tog ywj pheej thiab cov kev lag luam niaj hnub los txhim kho kev muag khoom hauv cheeb tsam.Txawm li cas los xij, nrog kev loj hlob ntawm kev lag luam e-lag luam thiab qhov tshwm sim ntawm kev xa tawm hauv online, cov neeg koom nrog kev lag luam yuav koom tes nrog cov neeg thib peb hauv online channels kom tau txais txiaj ntsig ntawm kev loj hlob ntawm e-commerce tiam sis nyob rau ob peb xyoos tom ntej no.
Tsis tas li ntawd, kev loj hlob ntawm kev lag luam yas hauv South Asian lub teb chaws xws li Is Nrias teb, Thaib teb thiab Indonesia yog tsim cov rooj tog yas ua lag luam hauv cheeb tsam.Kev loj hlob ntawm cov ntaub ntawv raw hauv zos ua rau cov tuam txhab rooj tog yas kom txo cov nqi tsim khoom thiab qhia cov qauv tsim tshiab ntawm tus nqi sib tw.
Cov neeg tsim khoom suav tias polypropylene yog ib qho tseem ceeb ntawm cov yas siv hauv tsev / sab nraum zoov kho kom zoo nkauj, vim nws muaj cov yam ntxwv ua tau zoo dua li lwm cov yas resins siv hauv cov rooj tog yas.
Polypropylene yog cov khoom siv rov ua dua tshiab, hloov tau yooj yim thiab ruaj khov.Nws qhov kub tsis kam yog siab dua li cov rooj tog yas dav dav, xws li high density polyethylene (HDPE) thiab polycarbonate (PC).Cov neeg tsim khoom tau cog lus los tsim cov polypropylene ua haujlwm siab nrog kev pab ntawm carbonate additives kom ua tiav kev txuag hluav taws xob ntau, txo cov nqi thiab txhim kho cov rooj tog zaum yas.
Nrog cov neeg siv khoom xav tau ntau ntxiv rau cov rooj tog yas zoo siv hauv thaj chaw nyob thiab kev lag luam, kev lag luam rooj tog yas kuj tseem txhim kho nrog kev tshawb pom ntawm thermoplastic.
Txhawm rau ua kom tiav, Nws ntseeg tau tias txawm hais tias muaj kev xav tau zoo rau polypropylene, polycarbonate, ABS (acrylonitrile butadiene styrene) thiab HDPE yuav dhau los ua cov khoom nrov hauv kev lag luam rooj tog yas hauv ob peb xyoos tom ntej no.Tsis tas li ntawd, cov tuam txhab yas resin tej zaum yuav ua kom muaj kev ua tau zoo ntawm cov resins kom tau raws li qhov xav tau ntawm cov rooj tog yas yas hauv ob peb xyoos tom ntej no.
