Cov khoom kub stamping ua los ntawm cov hlau txhuas ncaj qha dov rau hauv cov ntawv nyias. 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. Txawm li cas los xij, aluminium ntawv ci nws tus kheej yog ib qho yooj yim rau oxidize thiab darken nyob rau hauv cov xim, thiab yuav ploj mus thaum rubbed los yog kov, yog li nws tsis haum rau kub stamping ntawm lub sij hawm ntev khaws cia ntawm phau ntawv npog, thiab lwm yam.
Classification ntawm aluminium ntawv ci:
los ntawm thickness
Aluminium ntawv ci tuaj yeem muab faib ua cov ntawv tuab, ib qho xoom ntawv thiab ob npaug xoom ntawv raws li qhov sib txawv thickness.
①Thick foil: ntawv ci nrog lub thickness ntawm {{0}}.1 ~ 0.2mm.
② Ib qho xoom ntawv ci: ntawv ci nrog lub thickness ntawm {{0}}.01mm thiab tsawg dua 0.1mm /.
③Double-zero foil: Lub npe hu ua ob-zero foil yog ntawv ci nrog ob xoom tom qab tus lej lej thaum nws qhov tuab yog ntsuas hauv mm. Nws feem ntau yog cov ntawv txhuas txhuas nrog lub thickness tsawg dua 0.01, uas yog, aluminium ntawv ci nrog lub thickness ntawm 0.005 ~ 0.009mm.
los ntawm lub cev
Aluminium ntawv ci tuaj yeem muab faib ua yob aluminium ntawv ci thiab ntawv txhuas ntawv ci raws li nws cov duab. Aluminium foil sib sib zog nqus ua ntaub plaub yog feem ntau nkag rau hauv daim ntawv yob, thiab daim ntawv txhuas ntawv ci tsuas yog siv nyob rau hauv ob peb lub hnab ntim khoom siv tes ua.
Aluminium ntawv ci tuaj yeem muab faib ua cov ntawv tawv tawv, semi-hard foil thiab cov ntawv ci muag raws li lub xeev.
① Cov ntawv tawv tawv: Aluminium ntawv ci uas tsis tau softened (annealed) tom qab dov thiab tsis muaj residue rau saum npoo yam tsis muaj degreasing. Yog li ntawd, cov ntawv ci nruj yuav tsum tau degreased ua ntej luam ntawv, lamination, thiab txheej. Yog tias nws yog siv los ua cov txheej txheem, nws tuaj yeem siv ncaj qha.
② Semi-hard foil: Aluminium ntawv ci uas nws qhov hardness (los yog lub zog) yog nruab nrab ntawm cov ntawv ci tawv thiab cov ntawv ci mos, feem ntau yog siv rau kev ua haujlwm.
③Soft foil: Aluminium ntawv ci uas tau muab tag nrho annealed thiab softened tom qab dov. Cov khoom yog mos thiab tsis muaj roj seem ntawm qhov chaw. Tam sim no, feem ntau daim ntawv thov teb, xws li ntim khoom, cov khoom sib xyaw, cov khoom siv hluav taws xob, thiab lwm yam, siv cov ntawv mos.
Raws li lub xeev nto
Aluminium ntawv ci tuaj yeem muab faib ua ib-sab du aluminium ntawv ci thiab ob-sided du aluminium ntawv ci raws li nws qhov chaw.
① Ib-sided du aluminium foil: Ob chav dov aluminium ntawv ci. Tom qab dov, ib sab yog ci thiab lwm sab yog tsaus. Xws li txhuas ntawv ci yog hu ua ib-sab du aluminium ntawv ci. Lub thickness ntawm ib sab ntawm cov ntawv txhuas dawb feem ntau tsis tshaj o. 025mm ua.
②Ob-sided aluminium ntawv nyiaj: Ib daim ntawv txhuas dov ib leeg, nrog ob daim ntawv sib cuag nrog cov chais. Ob sab ntawm aluminium ntawv ci yog muab faib ua daim iav ob sab aluminium ntawv ci thiab zoo tib yam ob sab aluminium ntawv ci vim qhov sib txawv ntawm qhov sib txawv ntawm cov chais. Lub thickness ntawm ob-sided aluminium ntawv yog feem ntau tsis tsawg tshaj li 0.01mm.
