The maintenance and management of chemical reaction solution is very important on surface pretreatment, as well as the rinsing technique play an important role, because it may cause some problem in the product quality and production lines of surface pretreatment.
The inferior aluminum profiles is easy to deform when affecting by sunlight, air, rain, etc., which has great security risk in daily life. Let’s see what characteristics that inferior aluminum profiles have.
After the chemical or electrochemical polishing, then the anodizing treatment, the aluminum products will obtain a smooth and bright layer of oxide film, with a high transparency, at this time, the aluminum alloy surface is easy to obtain various colors by dyeing. In the field of industry, the anodizing treatment or chemical oxidation methods are becoming more and more widely used, it makes aluminum alloys to obtain a layer of oxide film, and to achieve a purpose of protection and decoration.
