How to Improve the Acid and Alkali Resistance of Aluminum Stage Trusses?

Because the aluminum alloy Stage Truss is welded with high-strength aluminum alloy material, and aluminum itself is a relatively active metal component, it is easy to chemically react with the external acid and alkali. If it is in the water for a long time, the aluminum component will also A chemical reaction takes place in the water. In order to provide the stability of the performance of the aluminum alloy stage truss, the technicians have improved the acid and alkali resistance, oxidized the aluminum alloy stage truss, and attached an oxide film on the surface to prevent the external matter from the Aluminum Truss. 

Stage Truss

In order to overcome the defects of aluminum alloy surface hardness and wear resistance, and extend the service life of Aluminum Stage Truss, surface treatment technology has become an indispensable part of aluminum alloy use. Metal oxide films alter surface conditions and properties such as surface coloration, improved corrosion resistance, enhanced wear resistance and hardness, and protection of metal surfaces. For example, aluminum is anodized, and the aluminum alloy is placed in a corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is performed under specific conditions and an applied current. The aluminum of the anode or its alloy is oxidized, and a thin layer of aluminum oxide is formed on the surface thereof, and the thickness thereof is 5 to 20 μm. The anodized aluminum or its alloy improves the hardness and wear resistance. Handling the surface of Aluminum Stage Truss is a great way to improve the acid and alkali resistance of stage trusses.
