Tsev neeg Aluminium Ntawv Nyiaj

Cov ntawv txhuas hauv tsev yog ib daim ntawv nyias, hloov tau los ntawm txhuas, feem ntau nrog lub thickness ntawm {{0}}.016 hli thiab 0.024 hli. Nws du, nws yog xim hlau nyiaj saum npoo muaj ib sab ci ntsa iab thiab sab matte. Cov ntawv ci ntawm cov txiv neej ua haujlwm yog vim yog ntim ntom ntom txhuas atoms hauv nws cov qauv, cia nws tau yooj yim khoov lossis puab yam tsis muaj kua muag. Cov qauv no tseem muaj txiaj ntsig rau nws cov khoom tiv thaiv siab, ua rau nws impermeable rau lub teeb, huab cua, thiab noo noo, uas pab khaws cov zaub mov tshiab los ntawm kev tiv thaiv oxidation thiab paug. Aluminium lub ntuj muaj peev xwm los tsim ib txheej nyias oxide muab nws zoo heev corrosion kuj, ntxiv rau nws durability. Nrog lub thermal conductivity ntawm li 235 W / m·K, txhuas ntawv ci zoo hloov hluav taws xob, ua rau nws zoo tagnrho rau kev ua noj. Nws qhov ceev yog kwv yees li 2.7 g / cm³, nrog lub zog tensile ntawm ib ncig ntawm 70 MPa, kom ntseeg tau tias lub teeb thiab lub zog hauv kev siv txhua hnub.

Siab Malleability
Nrog lub thickness xws li {{0}}.016 hli mus rau 0.024 hli, txhuas ntawv ci tuaj yeem khoov tau yooj yim, folded, los yog qhwv. Qhov no malleability yog vim lub metallic bonding nyob rau hauv aluminium atoms, uas tso cai rau kom yooj yim txav ntawm cov khaubncaws sab nraud povtseg yam tsis muaj tearing. Qhov kev hloov pauv no ua rau cov ntawv ci kom nruj los yog qhwv cov khoom noj khoom haus, muab lub foob snug kom tsis txhob muaj kab mob.

Barrier Properties
Cov ntawv ci lub teeb meem yog ntaus nqi rau nws cov qauv ntom thiab ib txwm muaj oxide txheej, feem ntau {{1} 0 0 {0 {{1} 0 {{{1} 0 {0 0 0 {}} {{1} {0 {{}} Nrog rau qhov dej vapor kis tau tus nqi (WVTR) tsawg dua 0.01 g / m² ib 24 teev, aluminium ntawv ci muab ib qho yuav luag impenetrable shield tiv thaiv ya raws. Nws kuj muaj cov pa oxygen kis tau tus nqi (OTR) kwv yees li 0.0001 cm³ / m² ib 24 teev, tiv thaiv huab cua los ntawm kev nkag mus thiab ua rau oxidation. Cov khoom no tshwj xeeb yog qhov tseem ceeb hauv kev ntim khoom noj, qhov uas lawv pab khaws cov freshness, tsw, thiab cov as-ham rau lub sijhawm ntev.

Corrosion Resistance
Aluminium foil tsim cov txheej txheem tiv thaiv oxide, feem ntau nyob ib ncig ntawm 2-4 nanometers tuab, thaum raug huab cua, tiv thaiv corrosion. Cov txheej txheej oxide no ua rau muaj kev thaiv, tiv thaiv cov hauv paus txhuas los ntawm oxidation ntxiv. Txawm hais tias thaum sib cuag nrog cov khoom noj acidic (pH tsawg dua 4) lossis qhov chaw ntsev (sodium chloride concentrations txog 3.5%), cov ntawv ci tuav nws txoj kev ncaj ncees, tsis zoo li lwm cov hlau xws li hlau lossis tooj liab, uas tuaj yeem corrode los yog leach teeb meem tshuaj mus rau hauv. zaub mov. Qhov kev tiv thaiv corrosion no tso cai rau cov ntawv txhuas kom ruaj ntseg qhwv cov khoom acidic xws li citrus txiv hmab txiv ntoo los yog lws suav sauce yam tsis muaj kev cuam tshuam cov zaub mov saj lossis kev nyab xeeb.
