Abstract

The present invention discloses a 3003 reflective foil aluminum alloy. The aluminum alloy comprises silicon, iron, copper, manganese, zinc, magnesium, titanium, and inevitable impurities, and the balance being aluminum. A processing technology includes preparing raw materials, smelting, smelting in a holding furnace, grain refinement, online degassing and deslagging, filteration deslagging, continuous casting and rolling, cold rolling, finish rolling, cutting and packing. Though configuration of the above-mentioned material composition and the processing technology arrangement, the processed aluminum foil is enabled to obtain a large amount of small, uniform, and dispersed two-phase compounds and worked structures with uniform deformation; by using the potential difference between the two-phase compounds and an Al matrix electrode, an appearance of uniform and intensive corrosion pits is achieved for increasing the specific surface area of the aluminum alloy foil through a chemical corrosion treatment; and by using worked structures with uniform deformation, that the surface of the aluminum alloy foil has a high surface quality with uniform color after the corrosion treatment is guaranteed.

Description

technical field [0001] The invention relates to a processing technology of an aluminum alloy material and an aluminum alloy plate, in particular to a 3003 reflective foil aluminum alloy and a processing technology thereof. Background technique [0002] Increasing the specific surface area of ​​aluminum alloy foil is the key technology to increase the heat absorption area of ​​the core material of solar flat collectors. Its main purpose is to form dense porous W, Mo / Al on the surface of aluminum foil. 2 o 3 Coating, so that the size of the discontinuous void on the surface is equivalent to the peak of the visible spectrum (the energy of solar radiation is mainly distributed in the spectral region with a wavelength λ of 0.25 to 3 μm), thereby trapping visible light and improving the absorption of solar energy Rate. [0003] In the prior art, there are two manufacturing methods for increasing the specific surface area of ​​aluminum alloy foil, physical method and chemical met...
