In normal times, hardware buttons are often used to decorate clothes, shoes and bags. However, after using it for a long time, we will find that metal buttons are more susceptible to environmental influence due to their metal quality, and rust occurs. The light ones affect the appearance, and the heavy ones may lead to unusability and reduce the use value of the clothes. Therefore, for metal products, we should pay more attention to rust prevention in our daily life.

      What causes the surface of metal buttons to rust:

1. The humidity in the atmosphere is high. When the atmospheric humidity reaches a certain amount, water and oxygen combine, and a series of chemical reactions such as oxidation of the metal surface begin, resulting in rust on the surface of the metal button.

2. Corrosive gases. When the air contains a large amount of corrosive gas, the impact on the surface of the metal fastener is extremely large, and the influence of sulfur dioxide is the greatest. The main source of sulfur dioxide is the combustion of coal.

3. Dust in the air, such as smoke, coal ash, chloride and other acids, alkalis, salt particles, etc., are also extremely corrosive. If exposed to air and combined with water, it will become the strongest corrosion factor for metal products.

If there are metal buttons in the items we use, how can we prevent them from rusting?

The root cause must be cured first, and rust can be fundamentally prevented by finding the factors that may cause rust. Since rust is caused by factors such as humidity, high temperature, oxygen, sulfur dioxide, chloride, dust, etc., rust prevention is to avoid contact with these factors as much as possible. At present, the corresponding anti-rust work has been done in advance in the production of buttons.
