China Stud Bolt Manufacturer Introduces The Surface Treatment P


    China Stud Bolt Manufacturer introduces how to treat the surface of the nut:

    1. Electroplating the nut. Everyone knows that the nut will rust after a long time of use. Electroplating is to soak the rusted part of the nut in an aqueous solution. This aqueous solution is specific, and this aqueous solution contains a metal compound. , The surface of the nut can be processed by adding current. Nut electroplating generally includes zinc, copper, nickel, chromium, copper-nickel alloy and so on.

    2. Heating the nut, that is, hot-dip galvanizing. We know that some nuts are made of carbon steel. The nuts made of carbon steel are immersed in the molten zinc liquid, and then heated. The temperature must be higher. Only in this way is it conducive to the surface treatment. Generally, the commonly used heating temperature is 510 degrees Celsius. The nut will also produce iron-zinc alloy when used for a long time. After heating, this substance will change and transform. For the purified zinc without iron, the surface treatment of the nut is completed, which increases the service life and corrosion resistance of the nut.

    3. The third method is to use mechanical plating to perform the surface treatment of the nut. Simply put, mechanical plating is completed by a combination of physical and chemical properties. It uses metal-plated powder to stimulate the nut to be rusted. The surface of the nut is then cold treated. After the treatment, a coating will appear on the surface of the nut. This coating protects the nut and improves the service life and corrosion resistance of the nut. This is called coating, and this method is mainly used for screws and nuts, etc.
