Anti-rust paint and ordinary paint are two different types of coatings, which differ in performance, composition, and applicable scope. The specific differences are as follows:
1. Anti-Rust Performance: Anti-rust paint has excellent anti-rust properties and can effectively prevent oxidation and corrosion of metal surfaces, thus extending the service life of metal products. Ordinary paint does not have specialized anti-rust functions.
2. Composition: Anti-rust paint usually contains special components such as anti-rust agents and preservatives, which can form a protective film to block contact with air and moisture, thereby reducing the oxidation reactions of metals. Ordinary paint is primarily composed of pigments, solvents, and resins.

3. Applicable Scope: Anti-rust paint is mainly used for the protection of metal surfaces, such as steel structures, wrought iron, ships, and bridges. Ordinary paint is suitable for surface decoration and protection of various materials, such as wood, stone, and plastic.
4. Usage Environment: Anti-rust paint is usually used in outdoor environments, as it can withstand erosion from harsh weather conditions such as sunlight, rain, and wind. Ordinary paint is generally suitable for indoor environments and does not usually face harsh climate conditions.

In summary, compared to ordinary paint, anti-rust paint has better anti-rust performance and weather resistance, making it suitable for the protection of metal surfaces, while ordinary paint is more suited for general decorative and protective needs. It is important to choose the appropriate type of paint based on actual conditions and construction requirements.

It should also be noted that there are some differences in the application methods and precautions for using anti-rust paint and ordinary paint. When using, one should select the appropriate type of paint based on the specific situation.
