<p>Corrosion-resistant aluminum alloy pipe sheet technology Although aluminum and aluminum alloy naturally form a layer of oxide film in the atmosphere, the film is thin and loose porous, non-crystalline, uneven or  Vinyl Flooring Around Pool     discontinuous film, which can not be used as a reliable protective decoration Sexual membrane layer. With the continuous development of the aluminum products processing industry, anodic oxidation or chemical oxidation is more and more widely used in industry to form an oxide film on the surface of aluminum and aluminum alloy parts in order to achieve the purpose of protection and decoration.</p> <p> Oxidation film obtained by chemical oxidation Du Li, the thickness is generally 0.3 ~ 4um, soft, wear resistance and corrosion resistance are lower than the anodic  deck out of pallets     oxide film. Therefore, except for special purposes, rarely used alone. But it has better adsorption capacity, and then painted on its surface, which can effectively improve the corrosion resistance and decorative aluminum products. Anodizing is generally used.</p> <p> The anodized oxide film, the thickness is generally 5-20v m, hard anodized film thickness up to 60-2500m. It has a high corrosion resistance. This is due to the higher  rebar stair railing ideas     chemical stability of the anodized film. Aluminum and aluminum alloy corrosion-resistant characteristics of the difference: After testing, pure aluminum anodic oxide film than the anodic oxide film corrosion resistance. This is due to the inclusion of the alloy composition or the formation of metal compounds can not be oxidized or dissolved, leaving the oxide film is not continuous or voids, so that  accessories for floating decks     the corrosion resistance of the oxide film is greatly reduced.</p>
