1. Selection of dyes for aluminum oxidation equipment
There are many varieties of organic dyes, and dyes are selected according to different uses and product grades. For example, soluble vat dyes are expensive and have excellent color fastness. Therefore, they are mostly used for dyeing high-grade aluminum products such as gold pens, lighters and hearing aids; alcohol-soluble dyes are used for aluminum foil dyeing; oil-soluble dyes are used for printing aluminum foils, and are dissolved in nitrocellulose before use. In a lacquer such as a lacquer, a vinyl resin or a polyamide resin, or a melamine resin and an epoxy resin dissolved in a baking varnish, a resin film with a dye is formed on the surface of the cleaned aluminum foil after printing. The dyes used for dyeing aluminum products include acid dyes, acid complex dyes, acid medium dyes, direct dyes, weak acid dyes, disperse dyes, soluble vat dyes, reactive dyes, basic dyes, alcohol soluble dyes, oil soluble dyes, etc. .
2. Coloring process and control of organic dyes in aluminum oxidation equipment
(1) Monochrome dyeing: The aluminum product which has been anodized and washed with water is immersed in the dyeing solution at the specified temperature. The dyeing time is determined by the color depth, and the dyeing bath volume can be controlled to the volume ratio of the product: 1.
(2) Multi-color dyeing: If two kinds of different colors, such as landscapes, flowers and birds, tasks, texts, etc., are dyed on aluminum parts, the printing process is used to complete the printing plate (zinc plate, paper) Version) and screen version, direct printing method, paint anti-dyeing method, foam plastic dyeing method, etc. can be used. The general practice is to dye the first color, print the protective film on the part that needs to leave the color, and remove the remaining color. The second, third and more colors can be pushed in the same way.

Plastic Coated Composite Pipe
Plastic coated composite pipe is on the inner wall of the steel melts to dissolve a thickness of 0.5 ~ 1.0 mm layer of polyethylene (PE) resin, ethylene - acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or non-toxic polyvinyl chloride (PVC) and other organic matter and constitute a steel-plastic composite pipe material.
Advantage
Plastic coated composite steel pipe is protected by plastic coating both inside and outside. In the middle, it is used to strengthen the composite structure of welded steel pipe or seamless pressure steel pipe, which overcomes the defects of easy rust, corrosion, high pollution, low strength and deformation of plastic pipe, and integrates the common advantages of steel pipe and plastic products. it not only has steel tube high strength, easy connection, water resistance and other advantages, also overcomes the steel easy to corrosion, under the influence of water pollution, scale and strength of plastic pipe is not high, poor fire performance shortcomings, design life of 50 years.
