The reason of yellow color zinc plating on hose clamp mainly involves two aspects: galvanizing process and color treatment. The following is a detailed explanation of this phenomenon:
1. Galvanizing process
Galvanizing is a process of coating zinc on metal materials such as steel, the main purpose is to prevent corrosion of these materials. In the galvanizing process, the surface of metal products such as the hose band will first be derusted and pre-treated to ensure a good combination of the galvanizing layer and the substrate. Then, the zinc layer is evenly coated on the throat band surface by electroplating or hot plating.
Second, color processing
Color zinc plating process: Color zinc plating is a special galvanizing process, which changes the color of the galvanized layer by forming a colored film or interference film on the galvanized layer. This colored film may be formed by chemical reaction, electrochemical method or dyeing process. When the metal and the surface of the film reflect light, the light waves will cancel each other, resulting in a variety of different colors. Yellow zinc is one of the common colors.
Reasons for color change:
Film thickness: When plating colored zinc, the thickness of the film will affect the final color. As the film thickness decreases, the tone changes. Yellow zinc is usually formed when the film thickness is in a certain range.
Chemical reaction: In the process of zinc plating, the micropores on the metal surface will strongly adsorb inorganic or organic dyes in the dyeing solution, and dye the dye evenly to the metal surface through chemical reaction. This chemical reaction not only determines the color of the coating, but also affects its durability and corrosion resistance.
3. Application and advantages
The yellow zinc plating on the hose hoop not only improves its beauty, but also enhances its wear resistance and corrosion resistance. This treatment method has a wide range of applications in electrical equipment, nuclear industry, hardware and motorcycle parts. By plating yellow zinc, the hose hoop can better adapt to various complex environments and prolong the service life.
To sum up, yellow zinc plating on hose hoops is achieved through the combination of galvanizing process and color treatment. This treatment not only improves the beauty and durability of the hose hoop, but also expands its application field.
