1. After the nail is formed, polish it. The equipment used is: the polishing machine first adds sawdust and paraffin wax, and then pours the nails in. The polishing machine adopts a drum design. The nails, sawdust and paraffin wax can be used to remove rust and increase brightness under the action of friction. A protective layer is formed on the surface to make the nails not only bright but also resistant to storage. The cost of nail polishing is low, which is one of the more economical and practical methods.
2. The nails are galvanized. After the nails are formed and formed, they are galvanized. After the galvanizing treatment, the surface of the nails will form a protective layer. Not only the appearance quality of the nails is improved, but also the high temperature resistance and corrosion resistance are also improved. The nail galvanizing methods include electroplating and hot-dip galvanizing. The equipment requires galvanizing equipment and various chemicals. The nails are placed in an electroplating solution or connected by electric current. Or it can be combined with the nail surface through related physical and chemical methods to produce a good coating. This kind of coating can improve the strength of nails, so it is favored by many manufacturers. Nail galvanizing equipment can not only be used for the galvanizing of nails, but also can be used for galvanizing of various metal products, such as: iron wire, threaded nails , Insulation nails, corrugated nails, bolts, etc., but the nail galvanizing treatment equipment has a certain degree of pollution, and it is related to the output and the site, and the investment cost is greater than the polishing treatment equipment.
