How to improve the acid and alkali resistance

by:Shizhan     2020-05-17
First of all, this aluminum alloy truss is basically made of high-strength aluminum alloy materials by welding. The main reason is that aluminum is a relatively active metal component. It will easily react chemically with external acids and bases, so when If it is in water for a long time, then this aluminum component will also react chemically in water, so in order to provide stability of the performance of aluminum alloy truss, we need to improve its ability to resist acid and alkali, especially for aluminum alloy truss Oxidation treatment is carried out, so that an oxide film is attached to the surface to prevent the corrosion of the aluminum alloy truss by foreign substances. ????Among them, in order to overcome the problems of hardness and wear resistance of the aluminum alloy surface, we need to extend the use time, and the surface treatment technology has become an indispensable part of the use of aluminum alloys. In particular, the metal oxide film changes the surface state and performance, such as coloring on the surface, which can also improve corrosion resistance, enhance wear resistance and hardness, and thereby protect the metal surface. For example, aluminum anodizing, which can put aluminum alloy in the corresponding electrolyte as an anode, and still conduct electrolysis under specific conditions and applied current. For the anode aluminum or its alloy oxidation, a thin layer of alumina is formed on the surface to improve its hardness and wear resistance.
