What to do if it gets rusty
Rust is a common phenomenon in metal products, especially in humid environments. If left untreated, rust can further damage items. This article will introduce the causes, treatment methods and preventive measures of rust to help you effectively deal with metal rust problems.
1. Causes of rust
Rust is mainly the result of the chemical reaction between metal (especially iron products) and oxygen and water vapor. The following are common causes of rust:
| Reason | Description |
|---|---|
| humid environment | After being exposed to humid air for a long time, a rust layer is easily formed on the metal surface. |
| Chemical corrosion | Contact with acids, alkalis or salts will accelerate corrosion. |
| lack of protective layer | Metal that is not coated with anti-rust paint or coating is more susceptible to rust. |
2. How to deal with rust
Depending on the degree of rust and the material of the item, you can choose the following treatment methods:
| method | Applicable scenarios | Operation steps |
|---|---|---|
| Physical polishing | slight rust | Use sandpaper or a wire brush to buff away the rust until the metal surface is exposed. |
| chemical rust removal | Moderate rust | Soak with white vinegar, citric acid or commercial rust remover, then rinse with water. |
| electrolytic rust removal | Severe rust | Connect the metal to the negative pole of the power supply and put it in the electrolyte to energize it to remove rust. |
3. Recommendations for popular anti-rust products
The following are the most popular anti-rust products on the Internet recently for your reference:
| Product name | Features | price range |
|---|---|---|
| WD-40 rust remover | Quick rust removal, anti-rust protection | 30-50 yuan |
| 3M anti-rust spray paint | Long-term protection, multiple colors available | 60-100 yuan |
| Rust-Oleum anti-rust primer | Professional grade protection, strong adhesion | 80-150 yuan |
4. Measures to prevent rust
In addition to treating existing rust, preventing rust is more important:
| measures | Specific practices |
|---|---|
| keep dry | Use a moisture repellent or dehumidifier when storing metal items. |
| Regular maintenance | Apply anti-rust oil or lubricant to areas prone to rust. |
| surface treatment | Galvanize, chrome plate or spray metal products with anti-rust paint. |
5. Differences in anti-rust methods for different materials
The anti-rust methods of different metal materials are different:
| Material | Rust prevention points |
|---|---|
| Iron products | It needs to be completely isolated from air and moisture, and it is recommended to use anti-rust paint. |
| stainless steel | Clean regularly to avoid chloride ion corrosion. |
| copper products | It can be wiped with special copper oil to form a protective film. |
6. Precautions for rust treatment
Here are some things to note when dealing with rust issues:
1. Safety protection: Wear gloves and goggles when using chemical rust removers.
2. Environmental ventilation: Avoid using volatile rust removal products in confined spaces.
3. Moderate processing: Do not over-sand to avoid damaging the metal substrate.
4. Oil in time: Apply anti-rust oil or paint immediately after rust removal.
Through the above methods, you can effectively deal with metal rust problems and extend the service life of items. Remember, prevention is better than cure, and regular maintenance is the best strategy to prevent rust.
