The information of solar energy aluminum profile

solar energy aluminum profile
solar energy aluminum profile surface after the sand surface oxidation process is not easy to rust and corrosion of the aluminum oxide film in general is to 15u above. Other ordinary aluminum.
Aluminum is aluminum rod by hot melt extrusion, resulting in different cross section shapes of aluminum materials. The aluminum production process including casting, extrusion, and color of three processes. Among them, the color include: the process of oxidation, electrophoresis coating, fluorine carbon spraying, powder coating, wood grain transfer and so on.
Aluminum production process:
1, cast aluminum production process.
The main processes are:
Ingredients: (1) the need to produce a specific alloy grades to calculate the amount of the alloy composition, with a reasonable variety of raw materials.
(2) melting: with a good raw material according to process requirements to join smelting furnace melting, and through the degassing, deslagging refining means the melt miscellaneous residue, effectively remove gases.
(3) casting: melting a good liquid aluminum casting system, through the deep well in the casting process conditions, cooling the casting into a variety of circle casting rods.
2, extrusion: extrusion profiles forming the means. The first section design based on the profile products, manufacturing, mold, extruder heated to a good round casting rod extrusion from the mold. Commonly used grade 6063 alloy, extrusion also use an air-cooled quenching process and the subsequent artificial aging process, to complete the heat treatment to strengthen. Different grades of heat treatment to strengthen the alloy, its heat treatment system.
3 color (in this first talk about the process of oxidation)
Oxidation: squeezed a good aluminum extrusions, the surface corrosion resistance is not required by anodizing surface treatment to increase the degree of aluminum corrosion resistance, abrasion resistance and aesthetic appearance.
The main processes are:
(1) surface preparation: chemical or physical methods on the profile surface cleaning, exposed to the pure matrix, in order to facilitate a complete and dense artificial oxide film. You can also mirror or matt (matt) surface by mechanical means.
(2) anodic oxidation: surface preparation of the profile, under certain conditions, the surface of the substrate anodic oxidation layer of dense, porous, strong adsorption force AL203 film.
(3) sealing: the porous oxide film generated in the anodic oxidation film hole closed pores, pollution prevention, corrosion and wear resistance of the oxide film enhanced. The oxide film is colorless and transparent use of sealing the strong absorption of the oxide film, adsorption deposition of metal salts in the membrane pores, appearance can make profiles show true colors (silver white) other than in many colors, such as: black, bronze, gold and stainless steel color.
