Hardware buttons are very common on our clothing shoe bags. This material greatly enhances the texture of the clothing shoe bag. However, after a long time of use, we will find that the hardware buttons are more susceptible to environmental impact due to the metal quality. Rusty situation. Light affects the appearance of beauty, and severe cases may result in unusable clothing, reducing the value of clothing. Therefore, for metal buttons, we must pay more attention to rust prevention in daily life.
The main causes of metal button rust are these three points:
First, the atmospheric humidity is high. When the atmospheric humidity reaches a certain amount, water and oxygen are combined, and a series of chemical reactions such as oxidation begin to occur on the metal surface, which causes the surface of the metal button to rust.
Second, corrosive gases. When the air contains a large amount of corrosive gases, the impact on the surface of metal fasteners is extremely large, and the middle is the most affected by sulfur dioxide. The main source of sulfur dioxide is coal combustion.
Third, the dust in the air, such as smoke, coal ash, chloride and other acids, alkalis, salt particles, etc. are also extremely corrosive. If exposed to the air and combined with water, it will become the strongest corrosion factor of metal products.
If we use metal buttons in our articles, how can we prevent it from rusting?
The rule of thumb is to cure the root cause. Finding the factors that may cause rust can fundamentally prevent rust. Since rust is caused by factors such as moisture, high temperature, oxygen, sulfur dioxide, chloride, and dust, rust prevention is to avoid contact with these factors. At present, corresponding anti-rust work has been done in advance during the production of buttons. Such as: Add some elements in the metal smelting, improve the ability of the metal to resist the erosion of the external medium; Corrosion-resistant surface treatment of metal products, to form a surface conversion layer or add a surface coating; Cathodic protection, that is, the use of rust inhibitor Gas phase corrosion inhibitors, peelable plastics, and sealing methods temporarily isolate the metal surface from the external environment, and can also be successfully removed when the metal products are used. This method can be used for up to several years.
