Aluminium ntawv ci yog hais txog nyias strips ntawm txhuas thiab txhuas alloys nrog ib tug tuab ntawm tsawg dua los yog sib npaug rau 0.2mm. Nws cov nyhuv kub stamping zoo ib yam li cov ntawv nyiaj ntshiab, yog li nws tseem hu ua fake silver foil. Vim tias txhuas muaj qhov muag zoo nkauj, zoo ductility, thiab cov xim dawb dawb, yog tias daim ntawv calendered tau teeb tsa rau ntawm daim ntawv offset nrog sodium silicate thiab lwm yam khoom los ua aluminium ntawv ci, nws kuj tuaj yeem luam tawm. Aluminium ntawv ci feem ntau yog cais raws li thickness, xwm txheej thiab siv.
Raws li thickness: Txhua daim ntawv txhuas ntau dua {{0}}}012mm yog hu ua ib daim ntawv, thiab cov ntawv txhuas txhuas tsawg dua lossis sib npaug rau 0.012mm yog hu ua a ob daim ntawv; lub thickness nrog ib tug 0 tom qab tus zauv point kuj hu ua ib leeg-zero foil, thiab lub thickness nrog ob 0s tom qab tus zauv point yog hu ua ib tug xwb-zero foil. Muab ob npaug rau ntawv.
According to the state: it can be divided into full hard foil, soft state foil, semi-hard foil, 3/4 hard foil, and 1/4 hard foil. Fully hard foil refers to foil that has not been annealed after rolling (completely annealed coil and >75% txias dov); soft state foil hais txog cov ntawv ci uas tau ua tiav tag nrho tom qab txias dov; tag nrho txhuas ntawv ci tensile lub zog yog nruab nrab ntawm tag nrho cov tawv Semi-hard foil yog hu ua semi-hard foil ntawm ib daim ntawv ci thiab ib daim ntawv mos; 3/4 tawv ntawv ci muaj lub zog tensile nruab nrab ntawm cov ntawv ci tag nrho thiab cov ntawv ci ib nrab; aluminium ntawv ci muaj lub zog tensile nruab nrab ntawm cov ntawv ci mos thiab semi-hard foil. Qhov nruab nrab ntawm cov ntawv ci yog hu ua 1/4 hard foil.
Raws li qhov xwm txheej saum npoo: nws tuaj yeem muab faib ua ib leeg-sab ntawv ci thiab ob-sided lub teeb ci. Aluminium foil dov yog muab faib ua ib daim ntawv dov thiab ob daim ntawv dov. Thaum lub sij hawm ib daim ntawv dov, ob sab ntawm cov ntawv ci yog nyob rau hauv kev sib cuag nrog cov menyuam nto, thiab ob sab muaj ib tug ci xim hlau luster, uas yog hu ua ob-sided lub teeb ci. Thaum muab ob npaug rau dov, tsuas yog ib sab ntawm txhua daim ntawv yog nyob rau hauv kev sib cuag nrog cov menyuam. Sab hauv kev sib cuag nrog cov menyuam yog ci, thiab ob sab hauv kev sib cuag nrog ib leeg yog tsaus. Hom ntawv ci no hu ua ib leeg-sab teeb ci. Qhov tsawg kawg nkaus thickness ntawm ob-sided aluminium ntawv ci feem ntau yog nyob ntawm txoj kab uas hla ntawm txoj haujlwm yob, uas feem ntau tsis tsawg dua 0.01mm. Lub thickness ntawm ib sab aluminium ntawv nyiaj feem ntau tsis ntau dua 0.03mm, thiab tam sim no qhov tsawg kawg nkaus thickness tuaj yeem ncav cuag 0.004mm.
Raws li kev siv cov ntawv txhuas txhuas: nws tuaj yeem muab faib ua cov ntim txhuas ntawv ci, cua txias aluminium ntawv ci, hluav taws xob aluminium ntawv ci thiab roj teeb txhuas ntawv ci, thiab lwm yam.
