Printing plant oxidation sign production technology and characteristics

Printing is introduced oxidation brands production technology and characteristics of aluminium oxide plate produced by oxidation method has the following kinds: 1. Ac oxidation coloring, soft oxide film is suitable for stamping the convex word processing; 2. Sulfuric acid oxidation at room temperature for dyed black; 3. Sulfuric acid at low temperature oxidation, - - - - - - - > printing introduce oxidation brands production technology and characteristics of aluminium oxide plate produced by oxidation method has the following kinds: 1. Ac oxidation coloring, soft oxide film is suitable for stamping the convex word processing; 2. Sulfuric acid oxidation at room temperature for dyed black; 3. Sulfuric acid at low temperature oxidation, the oxidation film is meticulous and hard, suitable for dyeing native element, golden dye, etc. ; 4. Sulfuric acid, oxalic acid mixed acid oxidation can be obtained under the condition of the hard oxide film; 5. Ceramic oxide with chromic acid and boric acid anodic oxidation, surface with enamel. Printing is introduced which several methods commonly used currently in production of aluminum oxide plates are: aluminum oxide sign producing method is varied, the commonly used method is secondary oxidation method and the combination process. Examples are as follows: secondary oxidation: slice to mechanical polishing, chemical or electrochemical polishing to anodic oxidation, coloring and sealing hole back to screen printing text, graphics, membrane ( Oxide film) To the second oxidation, coloring and sealing hole to mechanical polishing, cutting and stamping forming. Combination process method: slice - brush grain - oxidation - gold - spray varnish to matching color offset printing, spray paint is to stick protective film to cutting and stamping molding, braille highlights cutting. Can combination process method are many, and screen printing, offset printing, electrophoresis paint, highlights, etching, sandblasting, cutting brush lines, etc. Craft combination. Printing is introduced the main characteristics of aluminum oxide plates is durable, light and wear-resisting, corrosion resistant performance is good. Mainly used in machine tool brands, sports device plate, senior cosmetic box and so on. Many novel aluminum oxide plates, especially multicolor printing and etching sign is mainly by oxidation process can be made out.
