Explanation of the causes of white spots on 3003 Aluminium Sheet
11-02
The 3003 Aluminium Sheet metal produced by the 3003 Aluminium Sheet manufacturer has strong mobility and is easily oxidized, but because it can form a fine aluminum oxide film (white) when it is oxidized, it should be normal to prevent continuous reaction with aluminum.
For 3003 Aluminium Sheet with strict appearance requirements, how to prevent white spots on the surface of 3003 Aluminium Sheet and make the product smooth and bright is not only related to the processing technology, but also closely related to the later surface treatment technology.
When processing large 3003 Aluminium Sheet alloy products anodizing, there will be white spots on the surface after the processing is completed, especially the oxidation of 3003 Aluminium Sheet is more obvious. Let's analyze the factors in this situation.
In fact, the main factor is very simple: after the 3003 Aluminium Sheet is oxidized, the washing is not complete, resulting in white spots on the surface after drying. The solution is to strengthen the washing after oxidation, and try to use a water gun to wash it completely. At the same time, in the future, you should pay attention to maintaining the appearance, try to keep the product from touching other products, and let it dry naturally.
That is to say, if you want to better control the vitiligo on the surface of 3003 Aluminium Sheet, you should not only pay attention to the appearance of the product during the product processing, but also pay attention to precautions in the surface processing and processing, so as to standardize the strict processing process and processing technology to prevent the formation of vitiligo. . It is OK to clean the vitiligo with acid washing and alkali washing, but control the concentration, or spray paint, to prevent the contact of aluminum and oxygen.
