Organic dyeing and electrolytic coloring difference in 1060 aluminum sheet dyeing process

News Details
1060 aluminum sheet is a very common method of processing. Especially the dyeing process of aluminum sheet is the most used in all kinds of aluminum sheet processing. It is the most widely used and used most and most in the past six months. Let's take a closer look at the dyeing of 1060 aluminum sheet. The difference between organic dyeing and electrolytic coloring in the process.Mingtai Aluminum can manufacture and supply high quality 1060 aluminum sheet with 18 years experience.

1060 aluminum sheet is a kind of light and soft non-ferrous metal, which is easily oxidized in the air, so people have come up with a solution, that is, the aluminum oxidation process, which grows a protective film on the outer layer to make it durable and dyeable. Colorful colors are pleasing to the eye.
1060Aluminum Sheet Features
♦ This series aluminum sheet, also called pure aluminum sheet, has the highest aluminum content among all the series produced. Its aluminum content can be more than 99.00%. the aluminum content of 1060 series aluminum sheet has to reach 99.6% or more.
1060 aluminum sheet characteristics
low density,
good conductivity and thermal performance
good corrosion resistance
good plastic processing performance
1060 aluminum sheet application
1060 aluminum sheet can be used in daily necessities, lighting appliance, baffle sheet, adornment, chemical industrial containers, heat sink, signs, electronics, lamps and lanterns, namesheet, electric equipment, stamping parts and other products.
The principle of aluminum anode treatment is a process of making decorative and protective films on articles made of aluminum and its alloys. The aluminum oxide film formed on aluminum is formed by passing a suitable sulfuric acid electrolyte at a sufficient voltage under direct current, wherein the aluminum of the object is an anode and the cathode is made of another material (lead or special graphite sheet). The industrial aluminum profile is energized for a certain period of time to gradually grow an oxide film of the desired thickness.
Organic dyeing and electrolytic coloring difference in 1060 aluminum sheet dyeing process
After the film is produced, in addition to some aluminum color does not need to be processed, the next step is to carry out coloring treatment. Generally, the coloring of aluminum is mainly divided into the following types:
1.1060 aluminum sheet organic dyeing
2.1060 aluminum sheet inorganic dyeing
3.1060 aluminum sheet electrolytic coloring
4.1060 aluminum sheet plating coloring
Below we mainly discuss the principles, advantages and disadvantages of commonly used organic dyeing and electrolytic coloring, and the product occasions used:
1. The electrolytically colored film is based on a transparent anodized film of primary electrolysis of sulfuric acid, and an oxide film (also called a secondary electrolytic film) which is electrolytically colored by alternating current in a solution containing a metal salt, and weather resistance, light resistance and use of the electrolytic colored film. The lifespan is much better than that of the dyed film, and its energy consumption and coloring cost are much lower than the overall colored film. Currently widely used in architectural aluminum profile coloring, but the electrolytic coloring tone is monotonous, usually only bronze, black, gold, and red. And the operation is not easy to control.
2. Organic dyeing, organic dyeing based on the theory of adsorption of matter, adsorption of physical adsorption and chemical adsorption, physical adsorption of industrial aluminum profiles is the adsorption of molecules or ions by electrostatic force; chemical adsorption, chemical adsorption, both Combined to produce organic dyeing, usually at a certain temperature. Due to the high porosity of the anodized film, the adsorption capacity is strong and easy to be organically dyed. This method is fast in color, bright in color, simple in operation, and sealed by dyeing after dyeing, and the dye can be firmly adhered to the pores of the membrane to improve the membrane layer. Anti-corrosion ability, anti-fouling ability, can maintain beautiful color, suitable for those large-scale aluminum daily necessities that do not need outdoor use, indoor aluminum industrial products and decorations, etc., the appearance is colorful and diverse. To meet the tastes of people in modern society to review and pursue beauty, and to improve the competitiveness of the product market. Organic dyeing has some characteristics and requirements for oxide film:
Organic dyeing and electrolytic coloring difference in 1060 aluminum sheet dyeing process
1. The oxide film layer should have sufficient porosity
2. The inner wall of the membrane pore maintains a certain activity
3. The anodized film of aluminum obtained in a sulfuric acid solution is colorless and porous, and thus is most suitable for dyeing.
4. The oxide film layer must have a certain thickness, and the thin film layer
