Easy installation, labor-saving compressed air line

China's production of aluminum alloy building profile products in the level, type and foreign equivalent. Products can be divided into: anodic oxidation colored profiles, electrophoretic painted profiles, powder sprayed profiles, fluorocarbon paint sprayed profiles, broken bridge insulation profiles. Aluminum alloy building profile products with high strength, light weight, corrosion resistance, decorative good, long service life, rich color and other advantages, especially through the choice of different colors and patterns, for the family decoration environment add luster.

The anodic oxidation method of aluminum is to put aluminum as an anode in the electrolyte such as sulfuric acid, apply anode voltage for electrolysis, and form a dense Al2O3 film on the surface of aluminum, which is a double-layer structure composed of a dense barrier layer and a porous layer with columnar structure. Anodic oxidation film can be divided into two categories: porous type - in sulfuric acid, oxalic acid and other acid electrolytic bath and form a very small hole perpendicular to the surface of the film; Barrier type - an extremely thin film without holes formed in an electrolytic bath of ammonium borate and other neutral salts. This film is usually used in electrolytic capacitors, etc.

Super aluminum alloy compressed air pipeline said that the concentration of Sn salt in the electrolytic solution is too low, the coloring speed is slow, when the concentration is higher than 25 g/L coloring speed is fast, but not easy to grasp, often produce a large color difference. The coloring temperature has a great influence on the coloring. When the temperature is lower than 15℃, the coloring speed is slow, and if the temperature is too high, the coloring film will be fogged. Moreover, Sn salt is easy to hydrolyze reversely, resulting in the turbidity of the bath.

However, in recent years, with the development of domestic aluminum alloy cable, dalian compressed air piping parts manufacturers began to focus on propaganda called rare earth high iron aluminum alloy cable, and announced that treated with rare earth aluminum alloy conductor in many properties such as conductivity, flexibility, creep resistance is relatively pure aluminium has increased significantly, some even claim that many excellent performance than copper conductor, brings rare earth treatment can make a qualitative leap to aluminum performance of illusion.

In response, the Chinese wire and cable standards committee director Chen Kun in the face of the media, such evaluation is given directly: "a lot of domestic enterprises is actually in the suit, disorderly make concept, like high iron alloy, rare earth high iron alloy and so on, all kinds of propaganda is multifarious, make people confused about, this is China's cable industry one of the irrational competition tactic."
