Both cold galvanizing paint and hot galvanizing are anti-corrosion methods with zinc as coating. Zinc is an active metal with very good cathodic protection characteristics. According to the electrochemical anti-corrosion mechanism, the zinc layer has excellent protection to steel. Cold galvanizing paint and hot galvanizing are common construction methods, but they still have great differences. Let's learn about them together.
Cold galvanizing paint and hot galvanizing are essentially different processes. Cold galvanizing paint is a paint spraying method, and hot galvanizing is a surface treatment process. With the increasingly widespread trend of environmental protection, the process of low pollution and low energy consumption is gradually favored. Compared with hot-dip galvanizing, cold galvanizing paint is an effective anti-corrosion method.
Hot dip galvanizing is to change zinc into liquid state by heating, immerse steel into solution pool, and zinc adheres to the steel surface to form galvanizing effect. This method will consume a lot of electric energy and heat energy, and cause serious environmental pollution. The improvement of industrial technology and the requirements of environmental protection make the application of hot-dip galvanizing process less and less.
