Puas yog Aluminium Ntawv Nyiaj Ua Los Ntawm Ntshiab Txhuas? Dab tsi yog Cov Khoom Siv Hauv Nruab Nrab?

Aluminium ntawv ci yog ntshiab txhuas.

Cov khoom kub kub stamping uas ncaj qha calendered rau hauv cov ntawv nyias nrog hlau aluminium. 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 nyiaj-dawb luster, yog tias daim ntawv dov yog ntsia rau ntawm daim ntawv offset nrog sodium silicate thiab lwm yam ntaub ntawv los ua cov ntawv txhuas, nws tuaj yeem luam tawm. Txawm li cas los xij, aluminium ntawv ci nws tus kheej yog ib qho yooj yim rau oxidize thiab xim yuav tsaus, thiab nws yuav ploj mus thaum rubbed los yog kov, yog li nws tsis haum rau kub stamping ntawm lub npog ntawm cov phau ntawv thiab lub sij hawm uas tau khaws cia rau lub sij hawm ntev.

Aluminium ntawv ci ntawv tsis yog ntshiab txhuas vim li hauv qab no:

1. Qhov saum npoo ntawm aluminium ntawv ci ntawv yog txheej ntawm aluminium oxide. Qhov saum npoo ntawm txhuas yog oxidized los ntawm huab cua los ua ib tug ntom aluminium oxide zaj duab xis. Qhov no ntom ntom aluminium oxide zaj duab xis tiv thaiv ntxiv oxidation ntawm txhuas.

2. Aluminium ntawv ci ntawv yog ib daim ntawv ua los ntawm aluminium foil backing paper thiab aluminium foil pasting thiab bonding. Aluminium foil thaub qab ntawv yog ua los ntawm cov ntawv sib xyaw thiab cov ntawv txhuas nrog cov nplaum, yog li cov khoom tseem ceeb yog ntawv, txhuas, thiab nplaum.

[Aluminium foil paper] yog ib daim ntawv nyias nrog lub thickness tsawg dua 0.2 hli ua tiav los ntawm aluminium ntawv ci dov zeb. Daim ntawv foil yog mos thiab yooj yim deformed, zoo li daim ntawv, thiab tsis thim rov qab tom qab deformation. Nws tuaj yeem ua tau zoo lav rau shading, yuav tsis poob, opaque, tsis muaj kuab paug, thiab pheej yig. Nws yog siv rau cov ntaub ntawv pov thawj noo noo thiab zoo nkauj ntim ntawm cov luam yeeb qib siab, khoom qab zib, thiab lwm yam khoom noj.
