Sign dry corrosion2020-03-11
The flat oxidation sign is an aluminum plate polished by mechanical or electrochemical methods, and then anodized with sulfuric acid as an electrolyte to generate a colorless and transparent oxidation strand. The film has a capillary conical groove structure, and the sign is made of pores. The rate is large, and it has strong adsorption capacity. After using glue, exposure and development with a photographic plate, and then dyeing and drying with live dyes (or acid dyes, direct dyes), so that the dye molecules are fixed inside the micropores of the oxide film, and are closed for dyeing purposes to form the required Signage.
The effect of the production of the plate of the flat anodized sign is based on the effect of the treatment before the anodization. It can be bright (machine polishing-degreasing-electrolytic polishing-film removal), sandblasting (alkali degreasing-sandblasting-dipping board). ), Drawing type (machine polishing-reeling-Tunping-left film). It can be selected according to different surface decoration requirements. Planar oxidation sign. The production of the sign has high work efficiency, clear writing, convenient dyeing, and abrasion resistance, oil fastness, and light fastness. In particular, the color of the oxidation dyeing is bright, transparent, thin, uniform and delicate. The production of panels has been widely adopted.
