Anodizing and chemical oxidation are commonly used in surface treatment of aluminum plate. The physical method is mechanical grinding, specifically sand blasting and wire drawing. Generally, this method is used for deep scratches.
If we just hope that the surface gloss is the same, the product and abrasive friction, polished the surface, for irregular products is feasible, the key is that the cost is low, generally there are external processing. Vibration polishing (with special
vibration polishing machine) can also be considered.
The lighter scratches can be completely eliminated after chemical polishing. The surface of the material is bright after chemical polishing. Put the product in, vibrate, rub the product with the
abrasive, polish the surface, and completely eliminate after chemical polishing. The surface of the material is bright and beautiful after chemical polishing.
Aluminum plate refers to the rectangular plate rolled from aluminum ingot, which is divided
into pure aluminum plate, alloy aluminum plate, thin aluminum plate, medium thick aluminum plate and patterned aluminum plate.
In the emerging application field, aluminum consumption should be gradually promoted through the concept change of color
coated plate manufacturers, technology maturity, policy guidance and support. It is understood that the current key areas of expanding aluminum applications include: transportation, building structures, and power fields. In addition, it also includes
aluminum alloy tray, aluminum alloy flood control facilities, aluminum alloy bridge, aluminum foil packaging and other products and fields.
Scope: expand the application of all aluminum trailer, aluminum alloy open top coal
truck, car high-precision aluminum alloy sheet.
Aluminum profiles used in the transportation field can effectively reduce the self weight, increase the payload and prolong the service life, which is of great significance to energy conservation and
emission reduction, improve the economic benefits of the transportation industry and highway transportation efficiency.
2. Field of building structure
Scope: expand the application of aluminum alloy building formwork and aluminum alloy enclosure
(1) expand the application of aluminum alloy building formwork
At present, the application proportion of aluminum alloy formwork in China is less than 1%. The requirements of large-scale construction enterprises for standardization,
industrialization and industrialization of construction, as well as the improvement of public requirements for housing quality, have greatly promoted the application of aluminum alloy formwork. In recent years, due to the rapid development of the real
estate industry, the production scale of China's construction formwork industry has maintained a growth rate of about 10-15%.
At the same time of the increasing consumption of domestic aluminum alloy templates, domestic enterprises also supply aluminum
alloy templates and aluminum profiles for templates to Brazil, India, Venezuela and Hong Kong and Macao, which will also promote the consumption of domestic aluminum.
(2) expand the application of aluminum alloy enclosure
In doestic civil
buildings, large-scale infrastructure projects, especially the projects with large span and complex shape, such as the roofs and walls of public buildings such as airport terminal, exhibition center, gymnasium, etc., have widely used aluminum alloy plates.
However, in industrial buildings, the proportion of steel structure system and metal plate enclosure system accounts for about 70% of the total construction, and aluminum alloy is rarely used.
With the increase of the demand for the overall, strategic
and public welfare engineering construction in the fields of agricultural infrastructure construction, indemnificatory housing project, reconstruction of rural dilapidated houses and so on, the demand for aluminum alloy enclosure board will be significantly
3. Power sector
China is short of copper resources and needs a lot of imports. The consumption of copper in the field of electric power accounts for more than 40% of the total consumption. Using aluminum resources, which has formed
a strong industrial foundation in China, instead of copper resources with insufficient guarantee, can reduce the external dependence of China's copper resources to a certain extent, and enhance the ability of resource guarantee.
(1) promote the
application of copper aluminum composite conductor
The copper-clad aluminum composite conductor is composed of aluminum core and copper cladding layer. Aluminum is used to replace the copper in the middle part of the conductor by using the "skin
effect" of current. By expanding the cross-sectional area of the conductor to compensate for the influence on the conductivity, the same conductivity of the color coated plate manufacturers can be achieved. Therefore, it is a kind of high-performance
composite conductor with the advantages of copper excellent conductivity, corrosion resistance, low cost and light weight of aluminum.
In addition, a series of steel (stainless steel) aluminum composite, titanium aluminum composite, aluminum aluminum
composite plates, strips, foils, and platoons have been developed in China, which are used in power, electronics, communication, heat dissipation, construction and other industries.
