Lub ntsiab lus luv luv ntawm Aluminium Ntawv Nyiaj

Cov khoom siv kub stamping ua los ntawm ncaj qha dov hlau txhuas rau hauv cov ntawv nyias, nrog cov kub stamping zoo ib yam li cov ntawv nyiaj ntshiab, yog li tseem hu ua fake silver foil. Vim lub mos mos thiab zoo ductility ntawm txhuas, nws muaj ib tug silver dawb luster. Yog tias daim ntawv nyias nyias yog ntsia rau ntawm daim ntawv nplaum nrog cov khoom xws li sodium silicate los ua aluminium ntawv ci, nws tuaj yeem luam tawm. Txawm li cas los xij, aluminium foil nws tus kheej yog nquag oxidation thiab darkening nyob rau hauv cov xim. Kev sib txhuam, kov, thiab lwm yam tuaj yeem ua rau xim fading, yog li nws tsis haum rau kub stamping ntawm phau ntawv npog uas tau khaws cia rau lub sijhawm ntev.
