Raws li cov ntaub ntawv txheeb cais, kev tsim khoom muaj peev xwm ntawm lub rooj sib tham hauv dej hauv Suav teb yog ze rau 2,000 tons hauv ib hlis xyoo 2023, uas yog qhov nce ntxiv piv rau 800 tons hauv ib hlis xyoo tas los.Txawm li cas los xij, lub peev xwm zoo li no tsuas yog suav tias yog ib feem me me hauv Tuam Tshoj txoj kev lag luam paperboard.Dej-raws li barrier board nyob rau hauv Tuam Tshoj yog tsuas yog rau ntim khoom noj, thiab tsuas yog muag rau txawv teb chaws lag luam.Txawm hais tias nws yuav txhawb nqa kev loj hlob zoo nyob rau yav tom ntej feem ntau nyob ntawm txoj cai xaiv hauv tsev thiab txawv teb chaws.
Los ntawm qhov chaw peb sawv, ntawm no yog cov qauv tseem ceeb ntawm cov dej-raws li barrier board.
Cov neeg siv khoom niaj hnub no tsis txaus siab rau qhov nruab nrab barrier zoo.Lawv tab tom nrhiav rau cov kev daws teeb meem kom ua tau zoo rau kev ntim khoom hauv ntau daim ntawv thov.Lub rooj tsavxwm yuav tsum yog cov kua thiab roj resistant nrog cov khoom tsim xws li qis qis vapor kis tus nqi (MVTR) lossis qis dua oxygen kis tus nqi (OTR), uas yuav tsum tau siv rau kev siv kawg.Piv txwv li, OTR, qis tshaj li 0.02 cm3 / m2 / hnub kom deb li deb, yog nyiam nyob rau hauv qhuav txiv hmab txiv ntoo ntim.Ib yam li ntawd, hmoov cov ntaub ntawv ntim yuav tsum muaj MVTR tsawg.Ib txwm siv acrylic dispersion tuaj yeem muab MVTR qhov tseem ceeb ntawm 100 mus rau 200g / m 2 / hnub, tab sis Kev Ua Haujlwm Zoo Tshaj Plaws (HPB) dispersion tuaj yeem muab MVTR tus nqi qis dua 50g / m 2 / hnub lossis txawm tias 10g / m 2 / hnub.
Kev maj mam hloov mus rau HPB los ntawm cov yas tau pom los ntawm kev siv HPB pawg thawj coj hauv qib kev lag luam.Tsis zoo li cov ntim khoom noj uas muaj kev nyab xeeb heev, kev ntim khoom lag luam qhia txog kev ua haujlwm tsis zoo thiab cov nqi tsim khoom.HPB ntim tuaj yeem muab faib ua cov ntim khoom lag luam thiab ntim cov khoom siv tshuaj txhua hnub.Kev ntim khoom ntau yog hais txog txhua yam ntawm lub hnab ntim khoom siv los tuav cov ntaub ntawv granular, xws li cov cement thiab tshuaj hmoov.Cov hnab ntim ntawv feem ntau muaj nyob ntawm qhov ntau thiab tsawg ntawm 25 kg lossis 50 kg.Water-based barrier, raws li lwm txoj hauv kev ruaj ntseg rau cov yas, tuaj yeem lav qhov kev sib khi ntawm cov cua sov thiab MVTR tus nqi kom zoo tshaj plaws kev txhawb nqa kev ua haujlwm ntawm cov ntawv ntim cov hnab ntim hauv cov khoom siv ceev ceev.Cov tuam txhab Pioneering uas txhawb kev tsim cov khoom HPB suav nrog Alou, BASF, thiab Covestro.HPB tuaj yeem muab qhov kev xav tau cuam tshuam kev ua haujlwm tab sis nws cov txiaj ntsig kuj muaj kev lag luam tawm.Tus nqi tsim khoom yog ib qho teeb meem ntawm nws txoj kev lag luam loj hlob.Cov khoom ntim tshuaj txhua hnub yog hais txog kev ntim cov khoom xws li tshuaj zawv plaub hau, tshuaj zawv plaub hau, thiab kev tu tawv nqaij, feem ntau yog cov hnab ntim ntawm ob peb puas grams mus rau ob kilograms.Kev ntim cov khoom siv tshuaj txhua hnub yog xav tau ntau dua nyob rau hauv cov nqe lus ntawm kev ua haujlwm tsis zoo tshaj li lub hnab ntim khoom.Nws xav tau cov khoom tseem ceeb xws li kev tswj cov av noo, airtightness thiab tiv thaiv lub teeb.
Muab qhov tseeb tias plastics tsis yog biodegradeable, cov khoom siv txuas ntxiv tau raug saib nrog kev pom zoo los ntawm cov neeg siv khoom zoo thiab cov khoom lag luam, cov neeg coob tshaj plaws yog cov teeb meem bio-based.Tau ntau tshaj ib xyoos, ob peb lub tuam txhab tau tshaj tawm lawv tus kheej cov khoom lag luam bio-based dispersion, txhawb kev thov hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog kev lag luam ntim khoom noj.Los ntawm kev cuam tshuam kev cuam tshuam rau kev luam ntawv inks, bio-based cov ntsiab lus ntawm cov khoom lag luam nyob nruab nrab ntawm 30% thiab 90%.Kev taw qhia ntawm cov ntaub ntawv nanocellulose ntxiv diversified lub portfolio ntawm bio-based barriers.Cov tuam txhab uas muab cov txheej txheem biodegradable muaj xws li Basf, Covestro, Siegwerk, Wanhua, Shengquan, Qihong, Tangju thiab lwm yam.Kev tshawb fawb tau tshwm sim nyob rau hauv ntau daim ntawv thov thiab kev lag luam, nrog rau kev ua ntawv, txheej txheej, tshuaj niaj hnub thiab roj teeb lub zog.Txawm li cas los xij, feem ntau cov kev tshawb fawb tau suav tias yog qhov tseem ceeb nyob rau theem no, kev tshawb fawb ntxiv thiab kev tshawb nrhiav pom tseeb yog xav tau.Kev tshawb fawb theoretical thiab kev siv tswv yim yuav tsum muaj kev sib raug zoo nrog ib leeg.Kev kawm thiab kev tshawb nrhiav yuav tsum dhau mus dhau Cellulose Nanofibrils (CNF) lossis Microfibrillated cellulose (MFC), txhawm rau muab ntau txoj kev xaiv rau cov neeg siv khoom xaiv ib qho uas tuaj yeem txhawb nqa lawv cov kev xav tau ntim.
80% ntawm qhov kev thov ntawm cov khoom lag luam ruaj khov yog los ntawm Tuam Tshoj txoj kev lag luam txawv teb chaws, xws li Europe, North America thiab Australia.Kev xav tau ntawm cov dej-raws li kev thaiv kev lag luam hauv Australian kev lag luam tau loj hlob ntau xyoo dhau los.Txoj cai txwv cov yas hauv Hong Kong kuj tau ua rau muaj kev loj hlob ntawm cov dej-raws li kev thaiv lub rooj tsavxwm.Nws qhov kev thov hauv tsev hauv Suav teb yog qhov tsis muaj zog tam sim no.Txoj kev loj hlob ntawm aqueous dispersion txheej tsis tsuas yog tso siab rau cov hom kev siv zog tab sis kuj yog kev lag luam txoj cai.Xyoo dhau los los yog li ntawd, cov tub ceev xwm hauv nroog hauv Suav teb tau hloov pauv los ntawm kev txhawb nqa cov yas biodegradable mus rau ntau yam khoom siv yas tsis muaj kev hloov, tshwj xeeb tshaj yog cov khoom siv rov ua dua tshiab thiab rov ua dua tshiab.
