Aluminum workpiece rust how to do?

Aluminum alloys are widely used in industry, construction, and home furnishing due to their excellent performance and beautiful appearance. However, even under the best use and maintenance conditions, aluminum alloy workpieces may rust. This article will provide you with a full range of solutions to aluminum alloy workpiece rust, to help you easily deal with this problem.

I. Understand the causes of aluminum alloy rust

First of all, we need to understand the reasons for aluminum alloy rusting in order to prescribe the right medicine. Aluminum alloy rust is mainly due to the following reasons:

1. the surface of aluminum alloy is oxidized: aluminum alloy in aluminum alloy is easy to react with oxygen in the air to form aluminum oxide, i.e. aluminum rust.
2. environmental factors: high humidity, salt, pollution of the environment will accelerate the process of aluminum alloy rust.
3. Improper maintenance: In the process of using, if there is oil, dust and other dirt on the surface of aluminum alloy workpiece, it will also accelerate the speed of rusting.

Second, the prevention and control methods of aluminum alloy rust

In order to prevent aluminum alloy workpiece from rusting, we can take the following measures:

1. Select high quality aluminum alloy materials: Selecting aluminum alloy materials with high corrosion resistance can effectively reduce the risk of rusting.
2. Surface treatment: Appropriate surface treatment of aluminum alloy workpiece, such as anodic oxidation, electroplating, spraying, etc., can increase the corrosion resistance of its surface.
3. Keep the environment dry: try to store the aluminum alloy workpiece in a dry environment to avoid rusting caused by humid air.
4. Regular cleaning: Clean the aluminum alloy workpiece regularly to remove the dirt and oxidized layer on the surface and prevent bacteria from breeding.
5. Moisture-proof and rust-proof: In humid seasons or environments, moisture-proof and rust-proof agents can be used to protect aluminum alloy workpieces from moisture erosion.

III. Treatment of aluminum alloy after rusting

When aluminum alloy workpiece appears rust phenomenon, you can take the following methods to deal with it:

1. physical method: for aluminum alloy workpiece with slight rust, you can use physical methods such as sandpaper and steel wire ball to remove the rust on the surface.
2. chemical methods: the use of dilute hydrochloric acid, dilute sulfuric acid and other chemical reagents, soaking rusty aluminum alloy workpiece, so that the surface of the rust is dissolved.
3. professional treatment: for the more serious rust phenomenon, it is recommended to seek professional aluminum alloy rust treatment services to ensure the integrity of the workpiece and extend the service life.

Summing up: aluminum alloy workpiece rust is a common phenomenon, but as long as you understand its causes, take appropriate prevention and treatment measures, you can easily deal with it. Hope this article can provide effective protection and maintenance guidance for your aluminum alloy workpiece.
