High strength bolt manufacturer, will discriminate and dissect the surface treatment of imperial nuts. How to distinguish the quality? The main thing is to check whether the corrosion resistance of the nut has been reasonably enhanced, and if so, whether the frequency of its enhancement is in accordance with the estimated regulations. After the surface treatment of the inch nut, the appearance will be more beautiful and generous, and the corrosion resistance will be improved, thus improving the application and stability of the inch nut.
The nut handling is divided into three methods:
1. Electroplating process. The electroplating process is a method of laying a layer of metal on a conductive body using the principle of electrolysis. Electroplating is a surface processing method in which a salt solution containing pre-plated metal is plated with the plated base metal as the cathode, through electrolytic action, so that the cations of pre-plated metal in the plating solution are deposited on the surface of the base metal to form a plated layer.
The properties of the plated layer are different from those of the base metal and have new characteristics. Depending on the function of the coating, it is divided into protective, decorative and other functional coatings.
When plating, the plated metal or other insoluble material is used as the anode and the workpiece to be plated as the cathode, and the cations of the plated metal are reduced on the surface of the workpiece to be plated to form the plating. It enhances the corrosion resistance of the metal (the plated metal is mostly corrosion resistant), increases hardness, prevents wear, improves electrical conductivity, smoothness, heat resistance and surface aesthetics.
2. Hot-dip galvanising. As we know, some of the English nuts are made of carbon steel, which is then infiltrated into a molten zinc solution and subsequently heated to a higher temperature, which is the only way to benefit the surface treatment. The surface treatment of the nut is then completed, thus increasing the service life and corrosion resistance of the nut.
3. Machinery and equipment plating. Simply put, mechanical equipment plating is the choice of physical properties and physical properties of the two fused together, it is the use of electroplated metal powder to stimulate the nut has long been rusted surface, and then to the nut to carry out cold violence, after processing the surface of the British nut will occur plating, this type of plating to protect the nut, so that the British nut's service life and corrosion resistance have been enhanced. This type of coating is called plating and is mainly applied to screws and bolts.
