Regarding cold-drawn zinc technology

I haven’t seen it being used widely; I only come across it occasionally – it’s a zinc-rich coating with a high content of zinc powder in it.

Speaking of cold galvanizing, I remember it was a concept introduced by the boss of my former company, with the aim of promoting the IC531 water-based inorganic zinc-rich coating. Later on, people began using this term everywhere. In my understanding, cold galvanizing is in contrast to hot galvanizing (such as dip coating or electroplating); the coating process does not require electricity or other thermal conditions, and the curing of the film takes place at room temperature. The zinc content in the cured paint film is very high (usually not less than 88%), meaning it is essentially pure zinc. Cold galvanizing and hot galvanizing each have their advantages. As we are all aware of hot galvanizing, let’s discuss the advantages of cold galvanizing over hot galvanizing: 1. It is environmentally friendly; water-based inorganic zinc-rich coatings contain no VOCs at all, making them eco-friendly and pollution-free ； 2 Energy-saving: no heat energy or electrical energy required; film formation at room temperature ； 3 Its corrosion resistance is better than that of hot-dip galvanizing (on this point, some people might not understand why a coating made of pure zinc isn’t the best option) This is because the role of zinc is mainly to protect steel through its own corrosion, that is, through cathodic protection. For this purpose, both hot-dip galvanizing and cold galvanizing are suitable. However, in hot-dip galvanizing, since it uses pure zinc, the current intensity is higher when zinc reacts, whereas in cold-dip galvanizing, which does not use pure zinc, the energy consumption is lower. ) Of course, I’m referring to water-based inorganic zinc-rich coatings. There are also products such as zinc-plus and high-strength zinc, which can all be considered cold-galvanized coatings; however, epoxy zinc-rich coatings don’t fall into this category, as their corrosion resistance is worse than that of the other types, and they cannot be used as standalone anti-corrosion coatings. The poster needs to specify the application scenarios, corrosion environment, and lifespan requirements for the steel structure that requires anti-corrosion treatment.

Under no circumstances agree. He will either apply a coating or electroplate a layer. And electroplating will **reduce protection
