Which industries are aluminum anodizing products mainly suitable for? There are three types of aluminum anodizing treatment methods, namely, high-temperature hydration reaction sealing, inorganic salt sealing and organic sealing. The birth of products has made human life more convenient. With the development of science and technology, continuous innovation and products are constantly being updated. Now products are used in all walks of life and are deeply loved by people.
What are the characteristics of the closed process of aluminum anodization?
(1) High temperature water sealing
This method uses the hydration reaction between aluminum oxide film and water to change the amorphous film into a hydrated crystalline film:
The hydration reaction can be carried out at room temperature and high temperature, but at high temperature, especially at the boiling point, the resulting hydrated crystal film is a very stable and irreversible crystal film. Therefore, the most commonly used aluminum oxide film sealing treatment is boiling water Method or steam method.
(2) Inorganic salt sealing
Inorganic salt method can improve the fastness of organic coloring dyes, so it is commonly used in chemical coloring methods.
①Acetate method
②Silicate method
(3) Organic sealing method
This is to immerse the aluminum oxide film with oil, paint or paint. Due to the high cost and increased process flow, it is not widely used. Most of the two methods mentioned above are used, and the first high temperature Water law is the mainstream.
