Recyclable ib qho khoom siv tau nyob rau hauv tag nrho viav vias nyob rau hauv lub domestic ntim lag luam. Txawm li cas los xij, feem ntau cov ntawv thov tseem muaj nyob hauv qee thaj chaw qis thiab nruab nrab. Yuav ua li cas siv cov khoom siv rov ua dua tshiab hauv qhov chaw siab barrier lossis txawm tias qhov chaw muaj kev kub ntxhov ntawm kev ua noj ua haus kub? Tam sim no, qee qhov chaw lag luam ib txwm tsim cov khoom siv ib leeg, puas ua tau raws li qhov yuav tsum tau ua dua tshiab? Ua ntej, dab tsi yog recyclable ib leeg khoom qauv? Txawm hais tias cov khoom siv rov ua dua tshiab tau nrov heev hauv kev lag luam hauv tsev, tab sis qee lub tuam txhab tsim cov khoom siv ib leeg hauv cov ntawv pov thawj rov ua dua, yuav tsis muaj feem pua ntawm cov nqi rov qab. Daim duab 1 qhia cov ntaub ntawv ntsuam xyuas ntawm tus nqi rov qab ntawm cov khoom ntim sib xyaw muab los ntawm "Institute Cyclos-HTP Institute of Germany", uas yog ib lub tuam txhab kev soj ntsuam thiab cov ntawv pov thawj ywj pheej. Tam sim no, nws tau tshaj tawm ntau txhiab daim ntawv pov thawj rov ua dua tshiab thoob ntiaj teb. Hauv Suav teb, ntau lub tuam txhab xws li Huizhou Baoba thiab Daoco kuj tau txais daim ntawv pov thawj los ntawm lub koom haum no. Cov kev rov qab los no yog cov txiaj ntsig kev sim ntawm cov khoom ntim khoom sib xyaw uas nws cov qauv tag nrho ua raws li cov qauv ntawm ib qho khoom siv. Vim li cas thiaj muaj qhov sib txawv loj?
Raws li European CEFLEX cov lus qhia thiab cov ntaub ntawv ntawm lub koom haum Cyclos-HTP nyob rau hauv lub teb chaws Yelemees, tus nqi rov qab ntawm high purity cov ntaub ntawv yog raws li nram no: ib leeg polypropylene zaj duab xis (PP), ib leeg polyethylene zaj duab xis (PE) thiab ib tug polyester zaj duab xis (PET) nrog rau siab tshaj tus nqi rov qab: High rov qab polyolefin composite qauv zaj duab xis: recyclable thiab nyob rau hauv cov ntaub ntawv tso cai PV-foil DC qauv, yuav tsum tsis txhob muaj cov ntaub ntawv uas tsis yog PV. Cov khoom siv (xws li number case, kua nplaum, aluminium plating, EVOH, thiab lwm yam) tag nrho tsis ntau tshaj 5%. Tso cai kom muaj cov khoom xyaw, yog nws cov ntsiab lus tag nrho, tsis yog cov ntsiab lus sib cais, uas yog ntau ntawm cov tuam txhab tsim cov khoom lag luam uas ua rau muaj kev ua yuam kev, uas ua rau cov nqi rov qab qis thaum muaj ntawv pov thawj.
Nqus evaporation txheej txheem tuaj yeem txhim kho ob qhov thaiv kev ua haujlwm ntawm cov dej thiab cov pa oxygen, uas kuj yog ib txoj hauv kev los txhim kho qhov ua haujlwm siab tshaj plaws nyob rau tam sim no, thiab cov txheej txheem nrog tus nqi siab tshaj plaws ntawm kev ua haujlwm ntawm dej thiab oxygen. Nqus evaporation yog ib qho ntawm cov txheej txheem nrog qhov tsawg tshaj plaws ntawm cov khoom tsis yog cov khoom tseem ceeb hauv tag nrho cov txheej txheem lifting barrier. Lub thickness ntawm txhuas plating txheej tsuas yog 0.02 ~ 0.03u, uas muaj ib tug me me feem ntau thiab tsis cuam tshuam rau lub hauv paus ntsiab lus ntawm recyclable thiab recyclable. Ntawm qhov chaw ntawm kev rov ua dua tshiab, cov txheej txheem txheej txheej siv dav tshaj plaws yog PVA txheej, uas tuaj yeem txhim kho cov pa oxygen ua haujlwm. Lub thickness ntawm txheej txheej yog hais txog 1 ~ 3u, suav rau ib qho me me. Nyob rau hauv cov nqe lus ntawm oxygen kuj muaj nuj nqi, nws yog ib tug nqi-zoo txheej txheem, uas ua raws li lub hauv paus ntsiab lus ntawm recyclable thiab recyclable. Tab sis PVA muaj ob qhov tsis muaj zog uas pom tseeb: ua ntej, nws tsis muaj dab tsi txwv dej; Qhov thib ob, nws yog ib qho yooj yim kom poob oxygen tsis kam ua haujlwm tom qab nqus dej. Ntawm qhov chaw ntawm kev rov ua dua tshiab, cov txheej txheem siv ntau tshaj plaws co-extrusion yog EVOH co-extrusion tam sim no, thaum siv dav siv PA co-extrusion tsis ua raws li txoj cai recyclable. Raws li txoj cai recyclable, PA raug txwv, thiab qhov siab tshaj plaws ntawm EVOH tsis ntau tshaj 5%. EVOH co-extrusion thickness yog hais txog 4 ~ 9u, raws li lub thickness ntawm cov khoom tseem ceeb yog txawv, EVOH co-extrusion txheej txheem yog yooj yim tshaj 5% ntawm qhov kev faib ua feem, tshwj xeeb tshaj yog nyob rau hauv lub zuag qhia tag nrho thickness ntawm nyias qauv, thiab nws barrier kuj muaj ib tug ncaj kev sib raug zoo nrog lub thickness. Raws li lub hauv paus ntsiab lus ntawm kev rov ua dua tshiab, EVOH raug txwv los ntawm kev faib ua ke ntawm qhov sib ntxiv thiab muaj kev txhim kho tsawg ntawm kev thaiv. Zoo li PVA txheej, EVOH tsuas yog txhim kho cov pa oxygen thiab tsis pab dej tsis kam. Raws li kev siv thev naus laus zis tam sim no, BOPP thiab PET zaj duab xis tuaj yeem ua tiav qhov zoo tshaj plaws tiv thaiv dej thiab oxygen. Bolene zaj duab xis lub siab tshaj plaws barrier ntawm aluminized BOPP, ob chav barrier hauv qab 0.1; Tam sim no, muaj cov thev naus laus zis paub tab los siv peb lossis ob txheej txheej txheej txheem rau nyias cov yeeb yaj kiab tib lub sijhawm, nrog cov txiaj ntsig zoo sib xws, txhawm rau ua kom muaj kev cuam tshuam zoo dua. Raws li cov cuab yeej paub tab tam sim no, cov lus hauv qab no teev cov yam ntxwv ntawm cov teeb meem loj ntawm cov khoom siv rov ua dua tshiab, thiab cov txiaj ntsig tau rov qab tau zoo ntawm txhua tus qauv thiab daim ntawv thov scenario nrog qhov zoo tshaj plaws.
