There are many kinds of organic dyes processed by alumina materials, and the dyes must be selected according to different uses and product grades. According to the field of application of industrial aluminum, industrial
aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. Soluble vat dyes are expensive and have excellent color fastness, so they are mostly used for dyeing high-grade alumina profile products, gold pens, lighters, and hearing aids; alcohol-soluble dyes are used for dyeing alumina profile foil; oil-soluble dyes are used for aluminum door aluminum foil For printing, dissolve in nitrocellulose, vinyl or polyamide resin lacquer before use, or melamine resin and epoxy resin in baking varnish, and clean the aluminum door aluminum foil after printing. Nominally form a resin film with dye. The dyes used in the dyeing of alumina profile products include acid dyes, acid complex dyes, acid preface dyes, direct dyes, weak acid dyes, scatter dyes, soluble vat dyes, reactive dyes, basic dyes, alcohol-soluble dyes, and oil-soluble dyes. Dyes, etc. The organic dye coating process of aluminum oxide profiles. Monochrome dyeing: The aluminum door aluminum products that have been anodized and washed with clean water are immersed in a dye solution at a regular temperature. The dyeing time depends on the color depth and the amount of dyeing bath. It can be controlled at a ratio of 10:1 to the volume of the product. According to the field of application of
industrial aluminum profile, industrial aluminum profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures. Multi-color dyeing: If you dye two different colors on alumina profiles, such as landscapes, flowers and birds, missions, texts, etc., use printing techniques to finish them. The printing plate can choose the type (zinc plate, paper Version) and screen version, direct printing method, paint anti-dyeing method, foam blasting method, etc. can be used. The usual method is to dye the first color, and then use a pattern to print the maintenance paint film on the part that needs to be colored, and then remove the remaining color. The second, third and more colors can be deduced by analogy. According to the field of application of industrial aluminum profile, industrial aluminum profile profiles refer to all aluminum profiles except for architectural doors and windows, curtain walls, indoor and outdoor decoration and aluminum profiles for architectural structures.
