Aluminum Background:

In 2020, the consumption of aluminum profiles in China will exceed 18 million tons

In terms of consumption of aluminum profiles, according to the research results of SMM on key enterprises, China's domestic demand for aluminum profiles is large. The production and sales ratio of China's aluminum profiles industry in the past five years is about 90%. Based on this, it is estimated that the consumption of China's aluminum profiles in 2020 will be about 18.02 million tons. The domestic demand is large, which is mainly due to the large number of consumers in China and the rapid development of the end consumer markets such as real estate and automobile market.

In the future, the use scale of aluminum profiles will continue to grow

Aluminum profiles are widely used in many fields because of their corrosion resistance, light weight and easy processing. For example, in the aspect of home decoration aluminum profiles, they have the advantages of long service life, environmental protection and energy saving, strong plasticity, good sealing performance, excellent weather resistance and elegant decoration effect. In addition, the aerospace and national defense industries also prefer aluminum products because of its light weight and corrosion-free characteristics. According to the consumption growth rate of aluminum profiles in China, it is expected that the domestic demand for aluminum profiles in China will reach 21.11 million tons by 2026.

Oxidation Types:

1. Chemical oxidation

At a certain temperature, a thin oxide film is formed on the surface of aluminum alloy profile through chemical reaction, which is called chemical oxidation of aluminum. This method does not need to pass through current, and the process is simpler and cheaper than electrochemical oxidation. The oxide film is very thin, and the film thickness is 0.5~4 μ M or so, the film is soft and has low wear resistance, so it cannot be used alone. The film has good physical adsorption capacity and is a good primer. The protective layer obtained by chemical oxidation can greatly improve the protective ability of parts.

2. Anodic oxidation method

Anodizing of aluminum alloy profile is made by electrolysis in oxalic acid, sulfuric acid and chromic acid aqueous solution with aluminum or aluminum alloy as anode and lead, carbon or stainless steel as cathode. Electro anodic oxidation can obtain film-forming speed that is difficult to obtain by natural oxidation. In the process of oxidation film formation, two processes occur at the same time: one is the formation of Al2O3 oxide film on the surface of aluminum plate; Second, the formation process of oxide film is accompanied by the dissolution of oxide film. Only when the formation rate of the oxide film exceeds its dissolution rate can a certain thickness of the oxide film be obtained, and the thickness of the film is generally 5~15 um. The film is a double-layer structure consisting of a dense barrier layer and a porous layer with a columnar structure. Anodic oxidation films of aluminum alloy profiles can be divided into two categories: porous films formed in acid electrolyzers such as sulfuric acid and oxalic acid, forming micropores perpendicular to the surface; Barrier film is a porous and extremely thin film formed in electrolyte, such as ammonium borate, which is commonly used in electrolytic capacitors.

Aluminium Window Door Profiles:

The aluminum alloy doors and windows we often say refer to the doors and windows made of aluminum alloy extruded profiles, window frames, mullions, and sashes. They are called aluminum alloy doors and windows, and are now also referred to as aluminum doors and windows. Compared with doors and windows made of other materials, aluminum alloy doors and windows have natural advantages.

01. Aluminum alloy doors and windows have light deadweight and high strength:

Aluminum alloy materials are mostly hollow thin-walled composite sections, which are easy to use, reduce weight, have a density of only 1/3 of steel, and the section has high bending strength. The doors and windows made of aluminum alloy materials are durable and have little deformation.

02. Aluminum alloy doors and windows have strong corrosion resistance

The aluminum alloy oxide layer does not fade or fall off, does not need painting, and is easy to maintain. The service life of the door and window control system is extremely long.

03. Elegant decorative effect of aluminum alloy doors and windows

The surface of aluminum alloy doors and windows is covered with artificial oxide film and colored to form a composite film. This composite film is not only corrosion resistant, wear-resistant, has a certain fire resistance, but also has a very high gloss.
