Tam sim no, muaj qee lub lag luam ntim khoom siv tau yooj yim sim siv cov khoom ntim yas degradable, cov teeb meem tseem ceeb yog:
1. ob peb ntau yam, me me tawm los, tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm pawg ntau lawm
Yog hais tias lub hauv paus rau degradation ntawm cov ntaub ntawv, fabrics, ntawm chav kawm, kuj yuav tsum tau tag nrho biodegradable cov ntaub ntawv, txwv tsis pub, lub hauv paus yuav degraded kiag li, peb tsis tuaj yeem siv roj av puag PET, NY, BOPP li ntaub kom phim cov khoom ntawm PLA composite. , yog li lub ntsiab lus yuav luag xoom, thiab zoo li yuav phem dua, txawm tias muaj peev xwm rov ua dua tshiab yuav ua tsis tiav. Tab sis tam sim no, muaj tsawg heev fabrics uas yuav siv tau rau composite saj zawg zog ntim, thiab cov khoom saw yog tsawg heev, thiab nws tsis yooj yim mus nrhiav tau, thiab lub peev xwm ntau lawm yog luv heev. Yog li ntawd, nws yog ib qho teeb meem nyuaj los nrhiav biodegradable fabrics uas tuaj yeem hloov mus rau cov pob muag muag.
2. Kev txhim kho kev ua haujlwm ntawm cov khoom siv degradable
Rau kev ntim khoom sib xyaw ua ke, cov khoom siv degradable uas tuaj yeem siv rau hauv qab yog qhov tseem ceeb tshwj xeeb, vim tias ntau lub ntim ntim tau tso siab rau cov khoom hauv qab kom ua tiav. Tab sis tam sim no tuaj yeem siv rau cov khoom ntim cov khoom sib xyaw hauv qab cov ntaub ntawv degradable, kev tsim khoom hauv tsev tuaj yeem muaj tsawg thiab deb ntawm. Thiab txawm tias qee qhov ntawm cov yeeb yaj kiab hauv qab tuaj yeem pom, qee qhov ntawm nws lub cev tseem ceeb xws li tensile, puncture resistance, transparency, heat sealing zog, thiab lwm yam, seb nws puas tuaj yeem ua tau raws li cov kev xav tau ntim uas twb muaj lawm tseem yog qhov tsis paub meej. Muaj cov cim qhia txog kev noj qab haus huv, teeb meem, tab sis kuj tseem yuav kawm seb puas yuav ua tau raws li qhov yuav tsum tau ntim khoom.
3. Txawm tias cov khoom siv pab cuam tuaj yeem degraded
Thaum pom cov ntaub thiab cov substrates, peb kuj yuav tsum xav txog cov khoom siv, xws li number case thiab kua nplaum, seb lawv puas tuaj yeem sib phim nrog substrate thiab seb lawv puas tuaj yeem degraded tag nrho. Muaj ntau qhov kev sib cav txog qhov no. Qee tus neeg xav tias tus cwj mem nws tus kheej yog ib qho me me, thiab qhov nyiaj tsawg heev, qhov feem ntawm cov kua nplaum kuj yog me me, tuaj yeem tsis quav ntsej. Txawm li cas los xij, raws li cov ntsiab lus saum toj no ntawm kev degradable kiag li, nruj me ntsis hais lus, tsuav yog cov khoom tsis tau raug decomposed tag nrho rau hauv yooj yim absorbed los ntawm cov xwm, thiab yuav tsum tau recycled nyob rau hauv cov xwm, nws tsis yog xam tau tias yog kiag li degradable.
4. Cov txheej txheem ntau lawm
Tam sim no, feem ntau manufacturers, kev siv cov ntaub ntawv degradable, muaj ntau yam teeb meem yuav daws tau. Txawm nyob rau hauv cov txheej txheem luam ntawv, los yog nyob rau hauv lub compounding los yog bagging, tiav lawm cov khoom cia txheej txheem, peb yuav tsum nrhiav kom paub seb qhov txawv no hom degradable ntim yog los ntawm cov uas twb muaj lawm roj av composite ntim, los yog dab tsi peb yuav tsum tau them sai sai rau. Tam sim no, tsis muaj kev tswj hwm zoo tshaj plaws lossis tus qauv tsim nyog rau kev siv nrov.
