Hauv kev tshawb nrhiav kev hloov pauv mus rau cov khoom siv hluavtaws, cov nplaum biodegradable tau los ntawm cov qos yaj ywm hmoov txhuv nplej siab tau txais txiaj ntsig zoo. Kev lig kev cai, cov nplaum hluavtaws, feem ntau siv hauv cov ntawv ntim khoom, yog tsim los ntawm cov khoom siv polymers uas tsis ua rau lub cev tsis zoo, ua rau muaj kuab paug ib puag ncig. Qhov kev thov nce ntxiv rau cov khoom lag luam ruaj khov, nrog rau cov kev cai nruj dua ntawm kev siv cov yas, tau tsav kev lag luam los tshawb nrhiav cov kev xaiv ntawm cov nplaum nplaum.
Dab tsi ua rau cov kua nplaum Biodegradable?
Biodegradable adhesives yog cov uas ib txwm decompose dhau sij hawm mus rau hauv cov khoom tsis muaj teeb meem xws li carbon dioxide, dej, thiab biomass. Raws li Duynie Group, tus kws tshaj lij hauv thaj teb, qos yaj ywm hmoov txhuv nplej siab, nrog rau cov pob kws thiab cov hmoov nplej hmoov nplej, muaj lub hauv paus txuas ntxiv thiab biodegradable rau cov nplaum. Dab tsi teeb tsa cov qos yaj ywm starch sib nrug yog tias nws los ua cov khoom lag luam ntawm Fabkis kib thiab qos yaj ywm chips ntau lawm, ua rau nws muaj kev xaiv zoo dua los ntawm kev txo cov khoom pov tseg los ntawm kev lag luam zaub mov.
Txhawm rau tsim nyog raws li biodegradable, tsuas yog 20% ntawm cov khoom yuav tsum tau ua kom puas lawm, tab sis ntau biodegradable adhesives tsom rau ntau dua ntawm decomposition. Muaj plaub theem tseem ceeb ntawm biodegradability:
- Thawj biodegradation - Cov khoom siv hloov pauv los ntawm cov kab mob microorganisms, poob nws cov khoom ua haujlwm saum npoo av.
- Inherently biodegradable - Hais txog 20% txog 60% biodegradation, raws li ntsuas los ntawm OECD 301A-F cov qauv.
- Yooj yim biodegradable - Ntau tshaj 60% ntawm cov organic carbon tau hloov mus rau CO2 hauv 10-28 hnub.
- Qhov kawg biodegradation - Ua kom tiav biodegradation ntawm cov khoom, nrog tsawg kawg 60% tawg hauv 90 hnub, ua rau carbon dioxide, dej, thiab minerals.
Qhov zoo ntawm Biodegradable Adhesives
Kev siv cov kua nplaum biodegradable muaj ntau yam kev cuam tshuam zoo rau ob qho tib si ib puag ncig thiab kev lag luam. Piv txwv li, eco-friendly adhesives ua los ntawm tej yam ntuj tso khoom, xws li qos starch, tsis pab rau microplastic paug, ib qho teeb meem tseem ceeb nrog hluavtaws polymers. Thaum siv nyob rau hauv compostable ntim, cov nplaum enriches cov av es tsis txhob tso cov teeb meem residues tom qab.
Biodegradable adhesives kuj txo cov nqi pov tseg, raws li lawv tawg yam tsis tas yuav muaj tshuaj lom neeg, ua kom rov ua dua thiab pov tseg ntau dua. Lub teb chaws thoob ntiaj teb tab tom siv cov cai tswj hwm kom txo qis kev siv cov yas ntim khoom. Los ntawm kev hloov mus rau biodegradable kua nplaum, cov tuam txhab tsis tuaj yeem ua raws li cov qauv no xwb tab sis kuj txhim kho lawv ntsuab duab, txaus siab rau eco-conscious neeg siv.
Lub luag haujlwm ntawm Potato Starch hauv Adhesives
Qos yaj ywm hmoov txhuv nplej siab lub ntuj tsim ua rau nws tshwj xeeb zoo rau kev siv hauv biodegradable adhesives. Nrog lub siab viscosity thiab muaj zog nplaum nplaum, qos yaj ywm starch kua nplaum muaj kev ua tau zoo rau ntau yam kev siv. Nws yog tshwj xeeb tshaj yog pab tau nyob rau hauv daim ntawv ntim, xws li cov hnab ntim khoom noj ceev, cov hnab ntim hauv qab, thiab cov hnab nqa khoom, raws li nws dissolves yooj yim hauv dej thiab tsis xav tau cua sov ntxiv, ua rau kev txuag hluav taws xob.
Cov lag luam nyiam Novinexx tau tsim tshwj xeeb qos starch-raws li adhesives xws li P130 daim ntawv hnab kua nplaum thiab CPB daim ntawv sack kua nplaum. Cov nplaum no yog 94% biodegradable hauv 14 hnub, qhia txog lawv cov txiaj ntsig hauv kev txo cov kev cuam tshuam ib puag ncig. Los ntawm kev sib koom ua ke cov khoom no rau hauv lawv cov haujlwm, cov tuam txhab tuaj yeem ua cov kauj ruam tseem ceeb rau kev ua tiav lawv cov hom phiaj kev ruaj ntseg thaum pab txhawb rau kev lag luam ncig.
Biodegradable adhesives ua los ntawm cov qos yaj ywm starch sidestreams muab kev cog lus rau kev sib tw ib puag ncig los ntawm cov nplaum hluavtaws. Lawv lub peev xwm los decompose lawm, ua ke nrog lawv cov kev siv ntau yam hauv kev ntim khoom, ua rau lawv muaj txiaj ntsig zoo hauv kev hloov mus rau yav tom ntej. Rau kev lag luam nrhiav kom txo tau lawv ib puag ncig hneev taw, cov eco-friendly glues nthuav tawm lub cib fim kom muaj txiaj ntsig zoo rau ob lub ntiaj teb thiab lawv cov kab hauv qab.
