1.After the nail is formed, it is polished. The equipment used is: polishing machine.First add sawdust and paraffin wax, and then the nail into the polishing machine. The polishing machine adopts the roller design, the nail and the sawdust, the paraffin wax under the function of friction, plays the role of removing rust and increasing brightness, and forms the protective layer on the surface of the nail, so that the nail is not only bright but also storable.The cost of polishing nails is low and it is one of the economical and practical methods.
2.Nail galvanizing. After the nails are formed, they are galvanized. After galvanized, the surface of the nail will form a protective layer, which not only improves the appearance quality of the nail, but also improves the high temperature resistance, corrosion resistance and other aspects.
Nail galvanizing can be done by galvanizing or hot galvanizing, using galvanizing equipment and a variety of chemicals to place the nails in an electroplating solution, or by running an electric current to hold them together. Or through the relevant physical and chemical methods to make it combined with the nail surface, resulting in a good coating. This kind of coating can improve the strength of the nail, so by a lot of manufacturers favor, nail galvanized equipment can be used not only for the nail galvanized, but also can be used for a variety of metal products galvanized.,For example: iron wire, thread nail, heat preservation nail, corrugated nail, bolt, etc. However, the nail galvanizing treatment equipment has some pollution, and is related to the output and site, the investment cost is greater than the polishing treatment equipment.
