The definition of anodic oxidation oxidation: aluminum and aluminum alloy in the corresponding lithium battery electrolyte and corresponding technical standards, because of the effect of additional current flow, aluminum profile manufacturers in metal aluminum (anodic oxidation) on the formation of a layer of oxide film process. If not specifically noted, series 100 aluminum profiles are usually referred to as hydrochloric acid anodized oxygen

1, the effect of anodic oxidation oxidation

☆ Defensive ability

☆ Art Deco

☆ Insulation performance

☆ Improve the bond with organic chemical coating.

☆ Enhance the combination with organic mulch

☆ Other functions in development and design

2, aluminum alloy chemical conversion film solution (chemical oxidation, passivation, chromium)

★ The chemical conversion film of aluminum alloy is obtained by chemical oxidation, which can refer to MIL-C-5541.

★ Why to develop chemical conversion membrane solution of aluminum alloy

☆ Strengthen the anti-rust processing capacity of aluminum alloy.

☆ Can play a smooth touch electric Yin effect. (Before processing and producing aluminum profiles, a customer commodity provides conductive oxidation, and its goal is to play a stable circuit resistance and conductivity effect)

☆ Conversion film is thin (about 0.5~4um), soft, conductive, porous structure, excellent absorption capacity, usually as paint or other building coatings at the bottom.

☆ Do not change the physical properties of the material.

☆ Simple machinery and equipment, convenient practical operation, low price.

☆ Does not harm the product specification.

★ Conversion film thickness

Aluminum alloy surface of the chemical conversion film is about 0.5~4um thin, conversion film is a kind of gel, it is difficult to immediately accurate measurement, usually only weighing the product before and after the chemical oxidation of the workpiece net weight, or surface color and salt spray test to distinguish the corrosion resistance of oxidation film.

Anti-rust effect after scratch

The chemical transformation film on the surface of aluminum alloy is a kind of gel. The colloid solution can move after the transformation film is scratched, and the suspected glue around the scar will move to the scratch surface, combined together, again, prevent the aluminum alloy from being etched, and still have corrosion resistance.

Taken the tone

The color of aluminum alloy chemical conversion film is dark gray, milky white, light green, orange yellow, rainbow color, the final color of conversion film, by the selection of conversion film liquid, the actual operation of processing conditions.
