Aluminium ntawv nyiaj (los yog txhuas ntawv ci hauv American English; qee zaum hu ua tinfoil) yog txhuas ua los ntawm cov ntawv ci nyias. Cov ntawv ci yog hloov tau yooj yim thiab tuaj yeem khoov los yog qhwv ib ncig ntawm cov khoom. Cov ntawv nyias nyias nyias nyias thiab qee zaum laminated nrog lwm cov ntaub ntawv xws li yas lossis ntawv kom nws muaj zog thiab siv tau ntau dua.
Kev tsim cov ntawv txhuas txhua xyoo hauv Tebchaws Europe yog kwv yees li 800,{1}} tons (880,000} tons) thiab hauv Tebchaws Meskas, cov ntawv txhuas txhua xyoo yog kwv yees li 600,{5}} tons (660 ,000 tons) hauv xyoo 2003. Kwv yees li 75% ntawm cov ntawv txhuas txhuas yog siv rau ntim khoom noj, tshuaj pleev ib ce thiab cov khoom siv tshuaj, thiab 25% yog siv hauv kev lag luam (xws li rwb thaiv tsev, cables thiab electronics). Nws tuaj yeem siv tau yooj yim dua.
Aluminium ntawv ci hloov tin ntawv ci nyob rau hauv nruab nrab -20th caug xyoo. Hauv UK thiab Asmeskas nws feem ntau hu ua "tinfoil", ib yam li cov kaus poom hlau feem ntau tseem hu ua "tin poom". Metalized zaj duab xis yog qee zaum yuam kev rau aluminium ntawv ci, tab sis qhov tseeb yog ib zaj duab xis polymer coated nrog nyias txheej ntawm txhuas.
Txoj kev nruam nruam yog ntau zog tsawg zog thiab tau dhau los ua cov txheej txheem ntawm kev xaiv. Thaum tsim cov thicknesses hauv qab no 0.025 hli, nws yog ib qho nyuaj rau tsim yob nrog ib tug nplua txaus qhov sib txawv los tiv thaiv cov ntawv ci specifications thiab zam qhov no, ntxiv rau txo tearing, nce productivity thiab tswj thickness rau qhov kawg pass (1 mil), Ob daim ntawv yog dov ib txhij, ob npaug ntawm cov tuab ntawm qhov nkag ntawm cov yob. Tom qab dhau los ntawm cov chais, ob daim ntawv sib cais, ua rau cov ntawv ci nrog ib sab ci ntsa iab thiab sab matte.
Cov sab uas kov ib leeg yog matte thiab sab nraud yog glossy. Matte aluminium foil muaj qhov cuam tshuam ntawm 80%, thaum glossy embossed ntawv ci muaj qhov cuam tshuam txog 88%. Yog tsis muaj instrumentation, qhov sib txawv ntawm thermal kev ua tau zoo ntawm ob sab yog imperceptible. Raws li Kirchhoff txoj cai lij choj hluav taws xob, qhov nce hauv qhov cuam tshuam txo qhov nqus thiab emission ntawm hluav taws xob.
Aluminium ntawv ci yog dav muag rau cov neeg siv khoom lag luam, feem ntau yog yob 500 hli (20 ntiv tes) dav thiab ob peb meters ntev.
Aluminium ntawv ci kuj tseem siv tau rau cov khoom noj uas muag muag.
Zoo li txhua yam khoom siv hlau, txhuas ntawv ci yuav hnov mob thaum muab tso rau hauv lub microwave. Qhov no yog vim hais tias electromagnetic teb ntawm lub microwave induces ib tug tam sim no nyob rau hauv cov ntawv ci thiab tsim ib tug muaj peev xwm ntawm lub ntse ntsiab lus ntawm cov ntawv ci; yog tias lub peev xwm siab txaus, ib qho arc yog tsim nyob rau hauv cov cheeb tsam uas qis dua los yog txawm nyob hauv huab cua nyob ib puag ncig ntawm daim ntawv. Niaj hnub nimno microwave ncu yog tsim los tiv thaiv kev puas tsuaj rau cov kab noj hniav magnetron los ntawm kev xav ntawm lub zog microwave, thiab tuaj yeem siv aluminium encapsulation tshwj xeeb tsim rau microwave cua sov.
