coil nails for fencing

Did not do the adhesion test of powder spraying or fluorocarbon spray on the packaging galvanized wire, but there are two points for reference: one, in the sealed or air circulation environment, non-metallic volatiles can corrosion zinc coating; Second, zinc above 230 degrees (c) will brittle the base metal. After powder spraying and fluorocarbon spraying, it is necessary to bake at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in decreased adhesion of coating, and even leading to brittle situation of steel wire.

The service condition and service life of galvanized iron wire or components are closely related to the thickness of the coating. The more strict the use conditions and the longer the service life, the thicker the required layer of galvanized iron wire should be. Different products, according to the specific environment (temperature, humidity, rainfall, atmospheric composition, etc.) to determine the expected service life of the coating thickness, blind thickening will cause all kinds of waste. But if the thickness is insufficient, it will not reach the expected service life requirements. Different manufacturers, according to their own equipment conditions, in the case of determining the plating, the first preparation of a more complete and reasonable process flow, clear plating parameters, control plating solution concentration, standard operation.

However, in the actual production process, the wire may be affected by other factors that may cause the wire to lose its conductive properties. For example, if the thickness of the galvanized layer is too thick or the surface is not uniform, the current density on the surface of the wire will be uneven, which will reduce the electrical conductivity of the wire. Similarly, if the wire is stretched too much during wire drawing, it may cause the wire to break or the surface to deform, thus affecting its electrical conductivity.

Steel wire mesh is finished by fine welding of active welding equipment. The material can be divided into cold wire drawing, hot dip galvanizing, cold galvanizing, dip plastic, etc. To be used for bridge reinforcement, bridge deck pavement, building reinforcement, etc.
