Why do industrial aluminum equipment suffer frequent corrosion? Who is behind the scenes?

The insulating glass complete equipment manufacturer tells you: Industrial aluminum equipment is prone to corrosion and wear during use, which brings a lot of inconvenience to related operations. This article summarizes a variety of factors that can cause corrosion of aluminum equipment. Let’s take a detailed look at the reasons below.

1. Environmental factors

There are many environmental factors that affect the corrosiveness of industrial aluminum equipment. For example, ion species, ion concentration, and environmental ph value will all have a great impact.

After conducting experiments on the corrosion conditions of two aluminum alloys in different atmospheric environments, it was found that the ability to resist stress corrosion in different environments will be different, especially in marine environments, which are more sensitive because seawater contains a large amount of salt. Penetrating the surface of the aluminum alloy causes corrosion within it.

Why do industrial aluminum equipment suffer frequent corrosion? Who is behind the scenes?

Reliable data shows that when the concentration of nitrate solution reaches 30%, the corrosion of aluminum alloy will be accelerated, reaching the highest point when the concentration reaches 35%. However, in high-concentration nitrate solutions, the corrosion effect of aluminum alloys is not obvious. This is because the strong oxidizing property of concentrated nitric acid forms a dense oxide film on its surface, making it impossible for nitric acid to pass through the oxide film for reaction. .

2. Smelting factors

Smelting factors mainly include processing methods, heat treatment methods, and processing methods. If these are not sufficient and improperly handled, it will cause corrosion of industrial aluminum equipment. Therefore, in the processes of aluminum production, we need to strictly follow the regulations to process the steps to prevent stress corrosion of the equipment during future use.

3. Stress factors

Stress factors mainly include load size, loading direction, loading speed, etc. The loading direction needs to be perpendicular to the surface of the equipment to cause separation. If the direction of the force is not perpendicular to the surface, but is tilted at a certain angle, Stress corrosion will occur during long-term use.

4. Maintenance factors

No matter how good the performance and high-quality equipment is, it needs good maintenance measures, because industrial aluminum equipment is very easy to cause aging and wear during daily use, so we usually need to pay attention to its maintenance work, and wear is more important. Serious objects should be replaced in time to keep the equipment running efficiently.
