Aluminium ntawv nyiaj feem ntau yog hais txog cov ntaub ntawv txhuas uas muaj purity ntau dua 99.5% thiab thickness tsawg dua 0.2 hli. Lub thickness ntawm aluminium ntawv ci siv rau cov ntaub ntawv sib xyaw yuav thinner. Tau kawg, ntau lub teb chaws muaj cov kev cai sib txawv rau cov tuab thiab muaj pes tsawg leeg ntawm aluminium ntawv ci.
Txawm li cas los xij, hauv kev xyaum ntim khoom noj, txhuas ntawv ci tsis tshua siv ib leeg vim tias txhuas ntawv ci nws tus kheej muaj qee qhov tsis zoo. Piv txwv li, raws li txhuas ntawv ci yog ntxiv thinned, tus naj npawb ntawm pores yuav nce, uas yuav cuam tshuam rau cov khoom thaiv ntawm aluminium ntawv ci. Nyob rau tib lub sijhawm, nyias thiab hloov tau yooj yim aluminium ntawv ci muaj cov kev txwv hauv kev tiv thaiv kev ncab thiab shear, thiab feem ntau tsis tuaj yeem siv rau kev ntim khoom. Hmoov zoo, aluminium ntawv ci muaj qhov ua haujlwm zoo thib ob. Cov ntawv txhuas feem ntau tuaj yeem ua ke nrog lwm cov ntaub ntawv ntim khoom los ua cov khoom ntim khoom sib xyaw kom ua rau qhov tsis zoo ntawm cov ntawv ci txhuas, yog li txhim kho cov khoom ntim kev ua tau zoo ntawm cov khoom ntim khoom sib xyaw.
Peb feem ntau hu ua ib zaj duab xis uas muaj ob los yog ntau tshaj cov ntaub ntawv uas yog ib tug composite zaj duab xis, thiab ib lub hnab ntim los ntawm ib tug composite zaj duab xis yog hu ua ib tug composite film bag. Feem ntau, plastics, aluminium foil, ntawv thiab lwm yam ntaub ntawv tuaj yeem ua rau hauv cov yeeb yaj kiab sib xyaw los ntawm kev sib txuas los yog kev sib khi kom sov kom tau raws li qhov sib txawv ntawm cov khoom noj khoom haus. Hauv kev ntim khoom niaj hnub no, yuav luag tag nrho cov ntaub ntawv sib xyaw uas yuav tsum muaj opacity thiab siab barrier zog siv aluminium ntawv ci raws li txheej txheej thaiv. Qhov no yog vim hais tias txhuas ntawv nyiaj muaj cov hlau tuab tuab muaj cov qauv siv lead ua thiab muaj cov teeb meem zoo ntawm cov pa roj.
Hauv kev ntim khoom noj khoom haus hloov tau yooj yim, muaj cov khoom ntim khoom hu ua "nqus aluminized film". Puas yog nws zoo ib yam li aluminium foil composite ntim khoom? Txawm hais tias ob qho tib si muaj txheej nyias ntawm aluminium, lawv tsis yog tib yam khoom. Lub tshuab nqus tsev aluminium plating zaj duab xis siv txoj kev evaporation los txuas high-purity aluminium rau yas zaj duab xis nyob rau hauv lub tshuab nqus tsev, thaum aluminium foil composite cov ntaub ntawv ua ke aluminium ntawv ci nrog lwm cov ntaub ntawv los ntawm kev sib txuas los yog kub sealing.
Qhov sib txawv ntawm cov ntaub ntawv txhuas cov ntaub ntawv sib xyaw, cov txheej txheem aluminium-plated nyob rau hauv aluminium-plated zaj duab xis tsis muaj qhov thaiv cov nyhuv ntawm aluminium ntawv ci. Nws yog lub hauv paus zaj duab xis nws tus kheej uas ua lub luag haujlwm thaiv. Txij li thaum aluminium-plated txheej yog thinner dua aluminium ntawv ci, tus nqi ntawm aluminium-plated zaj duab xis yog qis dua li ntawm cov ntaub ntawv aluminium ntawv ci. Nws daim ntawv thov kev lag luam kuj yog dav heev, tab sis nws feem ntau tsis siv rau lub tshuab nqus tsev ntim khoom.
