  • Because of the beauty, art, or in specific severe corrosion environment, galvanized layer can be applied to the above paint duplex system, as long as the paint system selection is correct, easy construction, its anticorrosion effect is 1.5~2.5 times better than the single paint and hot dip zinc life combined. With zinc layer to protect iron and steel, in addition to hot dip galvanizing method, there are several other methods, generally widely used, corrosion prevention effect is good and good economic benefits, hot dip galvanizing method.

  • The insulation layer of large rolls of galvanized wire and rigid thermal insulation products can be bound with double strands of galvanized iron wire, and the binding interval shall not exceed 400mm. The pipe or corresponding equipment with nominal diameter equal to or greater than 600mm shall stop reinforcement after binding, and the enclosed galvanized steel wire must be winched. The iron or wood rod should be tightened, but the tightening level should be moderate, not too tight or too loose, and not damage the wire. The consumption of wire and steel wire is generally used in drawing process and galvanized disposal.

  • 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.
