Technology and application of blackening handle on industrial equipment surface
In our daily life, we often see that the surface of some metal products presents a deep black color, which is not naturally formed, but the result of a series of special processes. Among them, "the handle with black surface of industrial equipment" is one of the typical representatives.
The process of "blackening the surface of industrial equipment" refers to the process of producing a dense and uniform oxide film on the surface of metal materials after chemical reactions such as oxidation. This oxide film has good antirust performance and decoration, which can effectively improve the service life and aesthetics of products. For the parts that need frequent contact, such as the handle, the wear resistance and corrosion resistance can be improved by using the method of "blackening the surface".
This technology originated in the military field. In order to improve the weather resistance and concealment of weapons and equipment during World War II, the United States invented this technology and quickly popularized it. Subsequently, with the development of science and technology and the continuous expansion of market demand, "surface blackening" has gradually been applied to the manufacture of civil products, and has been widely praised.
So how to achieve "blackening the surface of industrial equipment"? Generally speaking, there are two main methods: one is normal temperature impregnation; The second is high temperature heat treatment. Among them, the former is suitable for the production of small batch or complex shape parts; The latter is suitable for large-scale standardized processing requirements. No matter which method is adopted, the factors such as solution composition, temperature and time should be strictly controlled to ensure that the final effect meets the requirements.
In addition to the advantages mentioned above, "blackening the surface of industrial equipment" also has the following remarkable characteristics:
1. Simple and quick operation;
2. Low cost and environmental protection;
3. Wide application range, which can be widely used for surface treatment of metal parts with different materials;
4. It can be used in combination with other coatings to further enhance the corrosion resistance.
Of course, everything has two sides. "Black surface of industrial equipment" is no exception. For example, because the protective layer is formed by chemical reaction, it will be gradually eroded when it is immersed in a solution with strong acidity and alkalinity for a long time; In addition, improper operation will also cause environmental pollution and other problems. Therefore, in the practical application process, it is necessary to comprehensively consider and select the most appropriate method and technical scheme according to the specific situation to achieve the best effect.
In a word, the appearance of "handle with black surface of industrial equipment" not only greatly improved the problem that traditional metal products are easy to rust, but also brought more convenience to people's lives. In the future, with the emergence of new materials and technologies, it is believed that "blackening the surface of industrial equipment" will be more widely used!
