  • 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.

When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.
