wrought iron nails

③ The galvanized iron wire shall not be damaged when it is tightened.

1. Principle. Because zinc does not change easily in dry air, and in humid air, the surface can form a very dense film of zinc carbonate, which can effectively protect the interior from corrosion. And when the coating is damaged for some reason and the matrix is not too large, the zinc and steel matrix form a micro cell, so that the fastener matrix becomes the cathode and is protected. It is widely used in automobile transportation and other industries, but what is needed is the trivalent chromium passivation layer, zinc nickel alloy plating closed coating, reduce the harmful and toxic layer of hexavalent chromium passivation.

Plastic spraying is also we often talk about electrostatic powder spraying, it is the use of electrostatic generator to make plastic powder charged, adsorption on the surface of the iron plate, and then through 180~220 DEG C baking, so that the powder melting adhesion on the metal surface, plastic spraying products are used for indoor use of the box, paint film flat or matte effect. Spray powder mainly acrylic powder, polyester powder, etc.

First of all, we need to understand that the electrical conductivity of the wire depends on its material and size, and is not affected by the surface treatment method. Whether galvanized treatment or wire drawing treatment, they are the surface of the steel wire treatment, will not change the basic physical properties of the steel wire, electrical conductivity will not be affected. Therefore, in theory, the galvanized wire drawing treatment should not have any effect on the electrical conductivity of the steel wire.
