Vim li cas Foil Classification Matters
Aluminium ntawv ci yog nkag rau hauv ntau qib, thiab kev faib tawm kom raug yog lub hauv paus ntawm txhua qhov tshwj xeeb. Cov neeg yuav khoom, converters thiab manufacturers cais cov ntawv ci los ntawm thickness, cov khoom daim ntawv, temper, deg mob thiab tom qab ua tiav los yog tiav. Cov kev faib tawm no pab xaiv cov ntawv ci tsim nyog rau kev ntim khoom, lamination, hluav taws xob, hluav taws xob, hluav taws xob- pauv, roj teeb thiab daim ntawv thov, thiab tiv thaiv cov nqi tsis sib xws ntawm cov khoom xaj thiab kev siv kawg.
Classification los ntawm Thickness
Cov ntawv tuab, lossis qhov ntsuas hnyav, npog kwv yees li 0.10-0.20 hli thiab yog siv rau cov thawv ntim khoom nruj, qhwv lub cable thiab lub ntsej muag rwb thaiv tsev. Ib leeg-zero foil npog 0.01 mus rau qis dua 0.10 mm thiab yog siv rau cov ntawv ci hauv tsev, ntim tshuaj thiab ntim khoom yooj yim. Ob chav-zero foil yog qis dua 0.01 hli, feem ntau 0.005-0.009 hli, thiab yog siv rau cov khoom qab zib qhwv, hau, ntim luam yeeb thiab xaiv cov ntawv thov hluav taws xob.
Tsis muaj ib tug universal ciam teb ntawm lub teeb -gauge thiab hnyav-gauge ntawv ci; qee qhov kev lag luam kev lag luam siv kwv yees li 40 micrometers ua qhov taw qhia siv. Cov neeg yuav khoom yuav tsum ua raws li cov qauv khoom siv thiab cov lus pom zoo, thiab paub meej tias cov tuab tuab tiv thaiv cov qauv xws li GB / T 3198, ASTM B479 lossis cov ntsiab lus ntawm EN.
Kev faib tawm los ntawm Daim Ntawv
Roll foil yog nkag rau hauv coils lossis yob thiab yog daim ntawv tseem ceeb rau kev tsim khoom, ua cov khoom noj rau kev luam ntawv, txheej, laminating, slitting thiab kev ua haujlwm. Daim ntawv foil yog muab los ua ua ntej- txiav cov ntawv rau cov ntawv thov uas tsis tas yuav tsum tau ua cov coil txuas ntxiv; qhov ntev thiab flatness yuav tsum tau teev raws li kev npaj siv.
Classification los ntawm Temper
Cov ntawv tawv tawv yog nyob rau hauv ib qho kev mob- tawv tawv, feem ntau tsis muaj qhov kawg tag nrho annealing, thiab muaj zog dua thiab nruj; nws yuav tsum tau ntxuav los yog degreasing ua ntej luam ntawv, txheej los yog laminating. Semi- cov ntawv tawv tawv yog ib feem muag muag, nrog cov khoom ntawm cov tawv tawv thiab cov ntawv ci tag nrho, thiab siv qhov sib npaug ntawm lub zog, hloov tau yooj yim thiab tsim kev ua tau zoo. Mos ntawv yog tag nrho los yog ntau yam annealed, muab siab yooj thiab formability rau tsev neeg ntawv ci, saj zawg zog ntim, lidding thiab tshuaj ntim.
Temper yuav tsum tsis txhob xaiv ntawm nws tus kheej ntawm tus txheej txheem kawg. Yuav tsum tau hardness, tensile zog, elongation, tsim kev ua tau zoo thiab deg huv si yuav tsum tau txiav txim siab ua ke.
Kev faib tawm los ntawm qhov chaw nyob
Ib - sab ci ci yog feem ntau tsim los ntawm dov ob txheej ua ke, muab ib sab ci ntsa iab thiab ib sab matte, thiab dav siv rau nyias tsev neeg thiab ntim ntawv. Ob-sab ci ntsa iab yog tsim los ntawm dov ib txheej tiv thaiv kev ua haujlwm yob kom ob tog tsim qhov ci ci. Lub ci-vim-matte sib txawv feem ntau yog tshwm sim los ntawm cov txheej txheem dov thiab tsis ib txwm qhia qhov txawv ntawm cov hlau nws tus kheej.
Classification los ntawm Finish
Cov ntawv ci dawb yog muab tsis tau luam tawm ntxiv, txheej, embossing lossis lamination thiab tseem hu ua zeb-cov ntawv ua tiav lossis tsis muaj coated. Embossed ntawv muaj ib tug mechanically textured nto uas ua rau kom qhov chaw nto thiab txhim kho cov tsos los yog nruj. Composite foil yog laminated nrog ntawv, yas zaj duab xis los yog lwm yam substrates rau saj zawg zog ntim thiab rwb thaiv tsev. Coated foil nqa lacquer, resin, xim los yog polymer rau kev tiv thaiv corrosion, kub sealing, adhesion los yog printability. Cov ntawv ci xim thiab cov ntawv luam tawm ntxiv cov xim tsis sib xws lossis cov duab kos duab rau kev kho kom zoo nkauj, cim npe lossis cim npe.
Alloy Selection Notes
1xxx-series alloys xws li 1235, 1050 thiab 1060 feem ntau yog siv rau kev dav dav -lub hom phiaj, tsev neeg thiab cov ntawv ntim khoom uas yuav tsum muaj siab purity thiab zoo formability yog yuav tsum tau . 8xxx-series alloys, tshwj xeeb tshaj yog 8011 thiab 8079, yog siv nyob rau hauv cov khoom noj khoom haus foil thiab 8079. ntawv ci{10}}xxx-series alloys xws li 3003 muab lub zog siab dua thiab siv rau cov cua sov-txheej txheem fin Tshuag thiab xaiv cov roj teeb lossis cov ntawv thov.
FAQ
Q: Ob npaug -zero aluminium foil yog dab tsi?
A: Ob npaug -zero foil yog qis dua 0.01 hli, feem ntau 0.005-0.009 hli, siv rau kev ntim khoom qab zib, hau, ntim luam yeeb thiab xaiv cov ntawv thov hluav taws xob.
Q: Qhov txawv ntawm ib- sab ci thiab ob- sab ci ci yog dab tsi?
A: Ib qho - sab ci ci yog dov ob txheej ua ke, muab ib sab ci thiab ib sab matte; ob- sab ci ci yog dov li ib txheej kom ob sab ci.
Q: Cov hlau twg yog qhov zoo tshaj plaws rau cov ntawv ntim zaub mov?
A: 8xxx-series alloys xws li 8011 thiab 8079 yog dav siv rau cov zaub mov thiab tshuaj ntawv ci; 1xxx alloys xws li 1235 kuj tseem muaj rau kev ntim khoom.
Q: Cov ntawv nplaum siv rau dab tsi?
A: Mos, tag nrho annealed ntawv ci yog siv rau cov ntawv ci hauv tsev, ntim tau yooj yim, lub hau thiab cov tshuaj ntim tshuaj uas xav tau kev hloov pauv siab thiab tsim tau.
Q: Dab tsi yuav tsum tau teev thaum xaj ntawv?
A: Qhia meej txog alloy, temper, thickness, dav, coil hnyav, deg mob, tiav, pinhole thiab roj-reidue yuav tsum, kam rau ua thiab tus qauv siv xws li GB/T 3198 los yog ASTM B479.
