Dab tsi suav ua Foil
Cov ntawv ci yog txhais los ntawm kev ntsuas, tsis yog siv. Hauv kev coj ua lag luam aluminium foil yog dov hauv qab li 0.2 hli, nrog rau feem ntau ntawm cov ntsuas ntsuas ntawm 6 thiab 100 micrometers. Cov ntawv ci hauv tsev thiab cov khoom noj khoom haus feem ntau zaum ntawm 10 txog 20 micrometers, semi-cov ntawv ntim khoom noj tsis zoo ntawm 30 txog 90 micrometers, cov ntaub ntawv tshuaj blister ntawm 20 txog 30 micrometers, thiab tam sim no-cov ntawv sau rau lithium- ion cells ntawm 12 microres. EN 546-2 teeb tsa cov cuab yeej cuab yeej cuab tam rau cov ntawv ci, thaum ASTM B479 / B479M npog cov ntawv ci rau cov ntaub ntawv yooj yim barrier.
Alloy xaiv ua raws li lub luag haujlwm. Aluminium 8011 yog tus qauv Al-Fe-Si tsev neeg thiab zaub mov- kev pabcuam alloy, nrog kwv yees li 0.6 txog 1.0% hlau thiab 0.5 mus rau 0.9% silicon, uas txhawb nqa lub zog yam tsis muaj kev mob hnyav. Cov qib purity xws li 1235 yog siv nyob rau hauv qhov chaw conductivity los yog mos, tuag{11}}fold nto teeb meem. Alloy thiab temper ua ke txiav txim seb lub foil tuag-folds, springs rov qab, los yog kua muag huv si ntawm lub kua muag{14}}tab kab.
Lub Barrier Advantage
Qhov tsis xws luag -dawb txhuas txheej yog opaque thiab impermeable rau gases, dej vapour, lub teeb thiab tsw ntawm gauges ntsuas nyob rau hauv kaum micrometers. Qhov ntawd yog ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm cov yeeb yaj kiab polymer, uas xav tau ntau txheej txheej los ua kom zoo ib yam. Thaum cov ntawv ci tuab tshaj li 9 micrometers, pinholes ua tsawg txaus tias cov dej vapor kis tau tus nqi poob mus rau theem uas nyuaj rau ntsuas ntawm cov khoom siv niaj hnub.
| Khoom | Yam nqi | Tswv yim tsim nyog |
|---|---|---|
| Qhov ntom | 2.70 g / cm3 | Tsawg nyhav ib square meter ntawm barrier |
| Thermal conductivity | Txog 237 W / mK | Ceev ceev, txawm tias tshav kub hloov hauv qhov cub thiab cua sov sealers |
| Deg emissivity, ci tiav | 0.03-0.05 Nws | Reflective rwb thaiv tsev kev ua tau zoo |
| Lub teeb kis tau tus mob | xoom tshaj 6 mus rau 9 micrometers | Tiv thaiv cov rog, vitamins thiab tshuaj los ntawm cov duab - degradation |
| Ua haujlwm kub ntau | tob khov rau qhov cub siv | Ib lub substrate rau tag nrho cov saw txias thiab rau ci |
Thermal thiab hluav taws xob zoo
Cov ntawv ci kis cov cua sov tom qab es tsis txhob tsom rau nws, uas yog vim li cas nws muab txawm tias browning nyob rau hauv qhov cub, tiv thaiv cov npoo muag thaum lub sij hawm ci, thiab tso cai rau cov cua sov sealers kom ncav cuag qhov kub zoo sib xws thoob plaws lub vev xaib dav. Tib yam khoom siv hluav taws xob ua haujlwm: cov ntawv ci tiv thaiv kev cuam tshuam ntawm electromagnetic, sib npaug ntawm cov ntaub qhwv cable, thiab ua raws li lub dav hlau hauv av hauv laminated boards.
Reflective rwb thaiv tsev yog lwm sab ntawm tib lub npib. Nrog rau qhov emissivity nyob ze ntawm 0.04, cov ntawv ci ci ntsa iab thaiv cov hluav taws xob hloov hluav taws xob, uas yog vim li cas cov ntawv ci -fab lub ntsej muag thiab cov ntawv ci laminates yog siv tom qab lub tshuab hluav taws xob, hauv cov ntaub qhwv thiab hauv cov ru tsev. Kev ua tau zoo nyob ntawm qhov sib txawv ntawm huab cua; ntawv ci nyob rau hauv kev sib cuag ncaj qha nrog ob qhov chaw tau txais tsawg dua.
Kev tsim khoom thiab nqi zoo
Cov ntawv ci ua haujlwm siab - cov cuab yeej hloov pauv ceev. Nws tuaj yeem luam tawm, lacquered, embossed, laminated rau ntawv lossis polymer zaj duab xis, thiab tuag -folded yam tsis muaj kev sib sau ua ke, thiab nws hloov pauv ntawm cov txheej txheem unwinds thiab nro. Vim tias cov txheej txheem ua haujlwm tsuas yog ob peb micrometers tuab, cov khoom siv tus nqi ib square meter ntawm barrier yog tsawg piv nrog ntau - txheej txheej polymer ntawm vaj huam sib luag.
Cov ntawv ci kuj zam rau kev ua kom tsis muaj menyuam thiab kev nyiam huv ntawm kev kho mob thiab tshuaj ntim khoom. Nws txais cov cua sov- foob lacquer rau lub hau hlwv, muaj sia nyob hauv chav ua kom tsis muaj menyuam hauv daim ntawv laminated, thiab muab kev tiv thaiv lub teeb uas yuav tsum tau ua rau lub teeb pom kev zoo - rhiab heev.
Recycling thiab Life-Cycle Position
Aluminium yog recycled yam tsis poob ntawm kev ua haujlwm zoo, thiab lub zog remelt yog ib feem me me ntawm thawj lub zog tsim khoom. Huv si, ib zaug - alloy foil trim yog ib qho tseem ceeb ntawm cov khoom seem, thiab cov ntawv tshaj tawm -cov neeg siv khoom siv cov ntawv ci tuaj yeem rov ua dua txhua qhov chaw sau khoom txais. Qhov kev txwv tsis pub siv yog kev sib kis: ntawv ci laminated rau ntawv lossis yas yog qhov nyuaj rau kev sib cais, yog li mono- cov khoom tsim thiab kev sau huv si ua rau cov khoom siv rov ua dua tshiab dua li cov hlau nws tus kheej.
Ob daim ntawv tsim ua raws. Ua ntej, khaws cov ntawv ci ntsuas kom tsawg raws li lub luag haujlwm thaiv kev tso cai, vim qhov kev ua haujlwm ntawm pinhole thiab tuag -fold tus cwj pwm, tsis yog tuab, feem ntau yog tswj hwm kev xaiv. Qhov thib ob, qhia kom meej qhov chaw ua tiav ntawm kev txhob txwm tshaj tawm: ci ntsa iab qhov chaw muaj kev cuam tshuam zoo tshaj plaws thaum tshav kub kub, thaum matte lossis lacquered nto daim ntawv cog lus zoo dua hauv lamination thiab luam tawm ntau dua.
Cov lus nug nquag
Q:Puas yog aluminium foil ua tiav kev thaiv kev ya raws thiab roj?
A: Ntawm qhov ntsuas siab tshaj li 9 micrometers, ib txheej ntawv ci tau zoo impermeable, yog tias nws yog pinhole -dawb. Hauv qab qhov ntsuas, pinholes thiab flex cracking cia ntsuas kev sib kis, yog li siv cov qauv laminated.
Q:Vim li cas foil hnov kub sai sai hauv qhov cub?
A: Txhuas ua cua sov ntawm kwv yees li 237 W / mK, nrawm dua li cov yeeb yaj kiab polymer. Thaum tshav kub kub ncav cuag cov zaub mov sai sai thiab kis mus rau tom qab, txo qhov kub thiab ua kom lub sij hawm luv luv.
Q:Cov hlau twg yog siv rau tsev neeg thiab zaub mov- ntawv ci?
A: Aluminium 8011 yog tus qauv Al-Fe-Si xaiv, feem ntau nrog 0.6 txog 1.0% hlau thiab 0.5 mus rau 0.9% silicon, uas ua rau muaj txiaj ntsig zoo ntawm qhov ntsuas ntawm 10 txog 20 micrometers.
Q:Puas yog foil thickness cuam tshuam rau cov cua sov sealing?
A: Yog. Cov ntsuas hnyav xav tau ntau lub zog foob thiab nyob ntev dua kom ncav cuag qhov kub thiab txias. Cov kev sib khi yuav tsum tau rov ua dua- siv tau thaum twg cov ntawv ci ntsuas lossis cov txheej txheem lacquer hloov.
Q:Puas yog aluminium foil reusable?
A: Cov ntawv ci huv, tsis muaj tshuaj lom tuaj yeem rov siv tau ntau zaus rau kev qhwv lossis npog. Kev siv rov ua dua txo nws txoj kev tiaj tus, yog li kev cuam tshuam thiab kev sib khi ua haujlwm poob zoo ua ntej cov hlau nws tus kheej degrades.
Q:Cov ntawv ci tuaj yeem nqa cov ntawv luam tawm?
A: Yog. Ntawv nyiaj txais flexographic, gravure thiab digital print, tab sis lub substrate xav tau ib tug primer los yog lacquer rau number case adhesion, thiab ci ci hloov xim number case zoo li piv nrog dawb zaj duab xis.
