In order to produce a hard, corrosion-resistant surface on the surface of aluminum (Al) profiles, we will anodize certain aluminum workpieces. This process can not only improve the performance of aluminum workpieces, but also improve the aesthetics of the workpieces. Aluminum profiles make aluminum one of the most important non-ferrous metals. Due to its good performance (small density, good plasticity and formability) and easy recycling, pure aluminum and aluminum alloys have become important basic materials in household appliances. It is widely used in the renovation of hot parts and conductive parts of home appliances. Aluminum profile brand China's aluminum, aluminum profile processing industry and non-ferrous metal industry's comprehensive strength has been continuously improved, and it has become the world's non-ferrous metals and aluminum. Powerful nations are moving forward. However, after the oxidation treatment of aluminum, some precautions need to be taken. Otherwise, the effect on the aluminum workpiece is not good, and even the aluminum material may be damaged in advance.

1. Hot water flushing. After oxygenation (Oxygen), aluminum (Al) pieces need to be flushed with hot water in order to age the film. However, the water temperature and time must be strictly controlled. If the water temperature is too high, the film layer is thinned and the color becomes pale. Similar problems will occur if the processing time is too long. The appropriate temperature and time are: temperature 40 ~ 50 ℃, time 0.5 ~ 1MIN.

2. Drying, it is better to dry naturally. Hang the washed aluminum parts diagonally on the shelf, and let the free water on the working surface flow down in the vertical direction. Water droplets flowing from the aluminum profile to the lower corners are sucked off with a towel, and the color of the film layer dried in this way is not affected and appears natural.

3. Aging. The aging method can be determined according to the climatic conditions. In the summer when the sun is strong, it can be exposed to the sun. In the rainy or winter, it can be baked in the oven (explanation: baking things with fire). The process conditions are: ) 40 ~ 50 ℃ time 10 ~ 15min

4. For rework of unqualified parts, unqualified conductive oxygen (Oxygen) film parts should be selected before the drying and aging process of aluminum (Al) profile. The surface of the aluminum profile maker is oxidized to look very beautiful and resistant to dirt. Once oiled, it is easy to clean. When assembling products, different profiles are used according to different load-bearing materials, and matching aluminum profile accessories are used, and no welding is required. It is more environmentally friendly, easy to carry and move, and easy to install and remove. After drying and aging, the film layer is difficult to remove and will affect the surface roughness of aluminum parts. For unqualified workpieces, we can take the following simple measures (indicating the problem): First, clamp the unqualified workpiece on the aluminum anode (oxidation) fixture, and then press the aluminum into sulfuric acid (chemical formula: H2SO4) Anodize the solution in the solution for 2 to 3 minutes to make the film soft and peel off. Then, after slightly cleaning the alkaline solution and ammonia nitrogen water (nitric acid), you can conduct conductive anodization again. Off.
