Hyperbolic aluminum sheet surface has a certain degree of oxidation will produce oxidation spots. How to deal with the oxidation spot on the surface of hyperbolic aluminum sheet?
- When the surface of hyperbolic aluminum sheet is oxidized and dirty, it can be cleaned with alkaline solution to remove the oxide film adsorbing dirt. After removal, wash several times with distilled water. It is then boiled in distilled water to close the holes in the oxide film. In this way, the surface of the cleaned aluminum plate will not absorb dirt.
- The surface of hyperbolic aluminum sheet is oxidized to form alumina, which is a dense protective film and reacts with acid and base. However, aluminum also reacts with acids and bases. Soak in dilute acid or alkali. When there is gas, remove it immediately and wash it with water or sand it with sandpaper.
- Before oxidation treatment of hyperbolic aluminum sheet surface products, chemical and physical methods should be used to clean the surface of the product, exposing the pure metal matrix, which is conducive to the smooth progress of oxidation coloring, so as to achieve a firm combination with the matrix.
