Selection of aluminum oxidation equipment dye

[China Aluminum Industry Network] 1. Selection of Aluminum Oxidation Equipment Dyes

A wide variety of organic dyes, dyes need to be selected according to different uses and product grades. Soluble vat dyes are expensive and excellent in color fastness, so they are mostly used in the dyeing of high-grade aluminum products, gold pens, lighters, and hearing aids; alcohol-soluble dyes are used in aluminum foil dyeing; oil-soluble dyes are used in the printing of aluminum foil and are dissolved in nitrocellulose before use. In lacquer such as enamel, vinyl resin, or polyamide resin, or in melamine resin and epoxy resin in baking paint, a resin film with dye is formed on the surface of cleaned aluminum foil after printing. The dyes used for the dyeing of aluminum products include acid dyes, acid complex dyes, acid mordant dyes, direct dyes, weak acid dyes, disperse dyes, soluble vat dyes, reactive dyes, basic dyes, alcohol-soluble dyes, oil-soluble dyes, etc. .

2. Aluminium oxidation equipment organic dye coloring process and control

Monochrome dyeing: The anodized aluminum products washed with water, immersed in the dye bath at the specified temperature, the color of the time depends on the depth of the color, the amount of dye bath can be controlled with the product volume ratio of 10:1.

Multi-color dyeing: If two or more different colors, such as landscapes, flowers, birds, tasks, texts, etc., are dyed on aluminum parts, the printing process is usually used to complete the printing. The printing plate can be used in the type (zinc plate, paper plate) and Screen version, direct printing method, paint anti-staining method, foam plastics, etc. can be used. The general method is to stain the first color, the part of the need to leave the color with a floral print protective film, the remaining color off, the second, third and more colors and so on.
