Extended information:

When the iron is left for a long time, it will rust. Iron is easy to rust, in addition to its active chemical properties, it also has a lot to do with external conditions. Moisture is one of the substances that make iron easy to rust.

However, only water does not make iron rust. Only when the oxygen in the air is dissolved in the water, the oxygen reacts with iron in a watery environment to produce iron oxide, which is rust. Rust is a reddish-brown substance. It is not as hard as iron and is easy to fall off. After a piece of iron is completely rusted, its volume can expand 8 times. If the rust is not removed, this spongy rust is particularly easy to absorb water, and the iron will rust faster. Iron will be heavier when it rusts, about 3 to 5 times its original weight.

The following methods can be used to prevent the nails from rusting:

1. Form an alloy to change the internal structure of iron. For example, adding chromium and nickel to ordinary steel to make stainless steel greatly increases the rust resistance of steel products.

2. Covering a protective layer on the surface of iron products is a common and important method to prevent iron products from rusting. According to the composition of the protective layer, it can be divided into the following types:

a. Apply mineral oil, paint or burn enamel or spray on the surface of iron products. For example, cars and buckets are often painted with paint, and machines are often painted with mineral oil.

b. Use electroplating, hot-dipping and other methods to plate a layer of gold du, such as zinc, tin, chromium, nickel, etc., that is not easy to rust on the steel surface. A dense oxide film can be formed on the surface of these gold zhi, so as to prevent iron products from contacting with water, air and other substances to rust.

c. Use chemical methods to form a dense and stable oxide film on the surface of iron products to prevent iron products from rusting.

3. Keeping the surface of iron products clean and dry is also a good way to prevent iron products from rusting.
