3. Aging: The aging method can be determined according to the climatic conditions. In the summer when there is sunlight, it can be exposed to the sun. The aluminum oxide can be baked in the rainy or rainy days in winter.
4. Repair of unqualified parts: Unqualified conductive oxide film parts should be picked out before the drying and aging process, because the film layer is difficult to be removed after drying and aging and will affect the roughness of the workpiece surface. For unqualified workpieces, we can take the following simple measures to resolve them.
First, the unqualified workpiece is clamped on the aluminum anodizing fixture, and then anodized according to the method of anodizing aluminum in sulfuric acid solution for 2 to 3 minutes. After the light is emitted, the conductive anodization can be performed again.
The aluminum oxide pendulum cesium art requires that the workpiece must be cleaned with organic solvents before the heat treatment or welding process is removed to remove the oil on the surface, but this is generally not possible at present. Therefore, a layer of oily sintered coke is formed on the surface of the workpiece. This layer of coking It is difficult to remove substances in organic solvents. If immersed in lye, it will cause local corrosion, pitting or unevenness, which will seriously affect product quality.
Pay attention to these details after the oxidation treatment of aluminum ingot china, in order to better ensure the product quality and use effect. Because of improper handling, it will affect the aluminum ingot workpiece to some extent, which may cause poor post-use effect. It is not impossible for the aluminum ingot to be damaged early.
